ЦитатаNew Rocket, White Tails In ULA's Long-Term Strategy
Feb 17, 2015 Amy Butler (http://aviationweek.com/author/abutler) Aerospace Daily & Defense Report

WASHINGTON and ORLANDO, Florida - United Launch Alliance's (ULA) plan to field a new rocket engine with Blue Origin called the BE-4 is only step one of a larger strategic plan to take the company fr om a sole-source benefactor mentality to competing in a burgeoning commercial market.
With that plan, ULA's current launchers - the Atlas V (developed originally by Lockheed Martin (http://awin.aviationweek.com/OrganizationProfiles.aspx?orgId=27191)) and Delta IV (developed originally by Boeing (http://awin.aviationweek.com/OrganizationProfiles.aspx?orgId=12083)) - will likely be supplanted by a new, yet-to-be-named rocket design within the next decade. The Atlas V and Delta IV are the workhorse rockets for the Defense Department (http://awin.aviationweek.com/OrganizationProfiles.aspx?orgId=29172) and have been since the early 2000s. But both have a limited future. Last year, former ULA Chief Executive Officer Mike Gass said the per-unit cost of an Atlas V 401 mission was $164 million; a Delta IV heavy mission was priced at $350 million. These prices are averages for the 36-core deal signed between ULA and the Air Force.
Atlas V - the Pentagon's rocket of choice for price and performance - is stunted due to tensions between Washington and Moscow over the latter's ambitions in Ukraine. Russia supplies the RD180 engine for it and Congress has mandated that no Atlas engines to be purchased can be used for national security missions. Delta IV has a stellar launch record but is more expensive. Nonetheless, its heavy variant is one of a kind and is the driving reason why the family will remain active into the future.
That is until ULA or another company can build a replacement. ULA CEO Tory Bruno, who was named to that position last August, abruptly replacing Gass, says the company is also developing a new upper stage to take the place of the legacy RL-10 built by Aerojet (http://awin.aviationweek.com/OrganizationProfiles.aspx?orgId=2026112) Rocketdyne and Dynetics that now mates with the Atlas V and Delta IV.
He is also reducing the company's infrastructure from five launch pads - supporting both launch vehicles - to two. One will be on each coast and will support operations for the Next-Generation Launch System (NGLS) as well as support the last Atlas V and Delta IV missions, Bruno told Aviation Week during a Feb. 17 interview. The company announced in 2008 it would drop one of its Delta II pads, leaving five pads in its infrastructure. The company oversees so many pads because it inherited both launch fleets supporting the Air Force's policy of maintaining two launch vehicles for assured access to space. The company eventually plans to go to two pads "just a couple of years after we introduce the Next-Generation Launch System," which is slated to be flight tested in 2019, Bruno says. "We'll be ramping up the new rocket and we'll be ramping down the Atlas and Delta so it'll be just a couple of years ... before we can retire the other pads and be completely dependent on the new pads."
The assumption is that the national policy will be filled in the future with two competing launch companies - not a single company managing two different rocket fleets.
In September Bruno and Blue Origin, a secretive Seattle-based company funded by Amazon.com founder Jeff Bezos, announced a partnership to develop the BE-4, a liquefied natural gas engine designed to both replace the RD180 in the Atlas V and to support the NGLS design. The BE-4 was originally being designed for Blue Origin's New Shepard Launch Vehicle, and the companies are scaling it up to produce about 550,000 lb. of thrust for Atlas V and NGLS - up to 15% more thrust than the RD180, Bruno says. "It is not a major amount of work having to be done over again in order to scale," he said. Two of the engines would be needed for the boost required by the Air Force.
The NGLS will be capable - when coupled with the new upper stage - to take over heavy payload missions now handled exclusively by the Delta IV heavy, Bruno says. Air Force certification for the engine is expected to take about one or two flights to achieve, Bruno says, adding that up to one year is likely required to allow the Air Force to review and qualify its hardware.
The company expects to require less time than SpaceX (http://awin.aviationweek.com/OrganizationProfiles.aspx?orgId=130904) needed to certify its Falcon 9 v1.1, in part because it has already included the Air Force in its design review process and because the new system will rely on legacy processes already approved for the Atlas V and Delta IV programs. The Air Force and SpaceX signed the cooperative research and development agreement on its Falcon 9 certification in June 2013; Teague says certification is likely this summer.
The near-term priority for ULA is to field the BE-4. The team is now testing components for it and "they are right wh ere I expected them to be" in development, Bruno said. Full-scale engine firings are slated for around 2017.
Bruno said ULA has a cost target for NGLS, but he declined to provide it.
Meanwhile, the Air Force is scrambling to devise an acquisition strategy to take advantage of both advances in the commercial market - SpaceX is also pushing for an upgraded Merlin engine and Aerojet Rocketdyne is developing the AR-1 as an RD180 replacement - as well as funding provided by Congress. Lawmakers set aside $220 million in fiscal 2015 to begin a next-generation rocket engine program, but the Air Force did not include a procurement strategy in its fiscal 2016 budget request sent to Congress Feb. 2. Experts estimate a new engine will cost at least $1 billion to develop, and the Air Force's fiscal 2016 request includes only $514 million through fiscal 2020. This is in part because the fiscal 2015 appropriation arrived so late, said Maj. Gen. Roger Teague, director of space program procurement for the Air Force secretary. It gave the Air Force little time to plan to use the funding.
Air Force Space Command (http://awin.aviationweek.com/OrganizationProfiles.aspx?orgId=25981) chief Gen. John Hyten says the strategy should be out in the spring or summer. It ultimately will call on industry for a large portion of the investment, Hyten told Aviation Week during a Feb. 12 interview at the annual Air Force Association Air Warfare Symposium in Orlando. "It is clear the Congress wants a competition as soon as possible," he said, adding that the Air Force wants to continue to purchase launch services rather than develop its own engine to be handed to industry as government-furnished equipment. "There are some very interesting engine development programs going on right now, so the first thing we have to do is to explore the public-private partnerships that can take advantage of the work that is already going on in industry ... We want to use our investment dollars to continue to explore those engine technologies. If we can't work those things out we have to basically figure out how to build an engine that can be used by anybody and get off the RD180."
Bruno, meanwhile, says ULA's partnership with Aerojet Rocketdyne to develop the AR-1 is a "backup plan" to the BE-4. The AR-1 is a kerosene engine also being designed as an RD180 replacement by Dynetics and Aerojet Rocketdyne. NASA (http://awin.aviationweek.com/OrganizationProfiles.aspx?orgId=19991) has invested about $50 million in risk-reduction work for this engine and advocates are hoping the Air Force will carry on the work, according to an industry source. Thus far, the team is conducting risk reduction for main injector stability, the source says. The Air Force recently signed a memorandum of understanding with NASA (http://awin.aviationweek.com/OrganizationProfiles.aspx?orgId=19991)'s Marshall Space Flight Center (http://awin.aviationweek.com/OrganizationProfiles.aspx?orgId=12090) allowing for the risk reduction to continue with Air Force oversight and funding. AR-1 advocates are arguing that the Air Force should build an engine directly and not contract simply for the launch services. The Air Force could do this using NASA as its technical overseer, they say.
Meanwhile, ULA is also planning to buy long-lead parts for "white tail" rockets - i.e., vehicles not yet sold - beyond the 36-core deal funded as a bulk buy by the Air Force. This is in anticipation of the company breaking further into the NASA market as well as the commercial market.
"We intend to go aggressively now after NASA commercial activities - cargo and crew - as well as pursuing [the] commercial market place which is largely comsats in the GEO orbit," Bruno says. "Some of these customers don't order so far in advance that it would be earlier than the long-lead part requirement, so that forces us to act like a commercial company like we are and anticipate the need and place those long-lead orders having confidence that we will sell them later."
The concept of building white tails was anathema to ULA only a year or so ago as the company was in the luxurious position of being the monopoly launch services provider to the Pentagon for large national security missions. Now, however, Bruno notes that the market has changed substantially, driving ULA to change with it.

Given that Jim's thread on the new Blue Origin engine for ULA has a tough time discussing things like solids in relation to the new LV, I thought I'd start a general thread for the new ULA launch vehicle. In the opening post, I hope to put all of the materials we've gotten on the LV and its core engines together.

What we know so far is that Blue Origin will be supplying United Launch Alliance (ULA) two 500 tf Liquid natural gas/oxygen BE-4 engines to power an all-new, Delta IV-diameter (5.1 m) core. The engine's likely Isp is believed to be roughly 309 seconds at sea level and 342 seconds in a vacuum (estimate by R7). These engines will power a stage that will be about 28 meters tall. According to Dr. Sowers of ULA, this stage will likely be mated to an existing upper stage at first, with the Centaur stage of the Atlas V and the 5 meter Delta Cryogenic Second Stage seen as the most likely. There is also the possibility of an upgraded upper stage eventually being built. Possible engines for such a stage include the hydrolox RL-10C, the hydrolox BE-3U, and a hydrolox XCOR engine.

NSF's resident LV simulator, Dmitry Vorontsov, has generously taken his time to simulate the possible capabilities of this new LV with various upper stages. His first simulation was of a fully-upgraded LV with a large upper stage and a core stage with a mass-saving common bulkhead. He has also simulated the possible performance of this LV with the 3 existing ULA upper stages. The simulation numbers are listed below:

BE-3U version of Atlas VI/Delta V

Rocket   Atlas 6/Delta V
Total Gross Mass   430 mt
Payload to GTO   8.85 mt
Payload to LEO   20.2 mt (all figures below are for GTO launch)
SI Gross Mass   362.36 mt
SI Propellant Mass   340.30
SI Separation Mass   22.06 mt
SI Diameter   5.1 meters
SI Engine(s)   2xBE-4 LNG/oxygen engines
SI SL Thrust   500 tf
SI Vac Thrust   557 tf
SI Isp SL/Vac   307/342 seconds
SII Gross Mass   56.30 mt
SII Propellant Mass   49.87 mt
SII Separation Mass   6.43 mt
SII Engine   1xBE-3U hydrogen/oxygen engine
SII Thrust (Vacuum)   50 tf
SII Engine Isp   450 Seconds
PLF Mass   2.478 mt
PLF Diameter   5.1 meters
Separation time   220 seconds
LV with existing ULA upper stages:
Atlas VI/Delta V w/Centaur: 7.2 mt to GTO (SEC)
Atlas VI/Delta V w/4 m DCSS: 7.9 mt to GTO
Atlas VI/Delta V w/5 m DCSS: 7.4 mt to GTO

There have been all sorts of things mentioned in connection with this LV. Like what SRBs, if any, will ULA mount on it IF it is to replace even the Delta IV Heavy rocket? Will they use the Delta IV's GEM-60s, which are meant for use with this core size, or will they use the Atlas V's SRBs? Will ULA be able to shut down all but a handful of pads moving to this new LV? Will this be enough to drastically cut ULA's costs and get them back into the commercial launch market? Will there be a universal PLF for the family? Will it be man-rated and launch the CST-100? There are plenty more things to discuss with regards to this family, so feel free to bring up any you think relevant.

ЦитатаEverything We Know about ULA's Next Rocket
by Mike Gruss (http://spacenews.com/author/mike-gruss/) -- March 11, 2015

WASHINGTON - Tory Bruno, the president and chief executive officer of United Launch Alliance, the government's primary launch services provider, has been dribbling out details on the company's next-generation rocket for weeks.
A formal unveiling of the rocket concept that will eventually replace ULA's Atlas 5 and Delta 4 launchers is planned for mid-April at the annual Space Symposium in Colorado Springs, Colorado.
In the meantime, Bruno will be taking questions fr om Reddit users at 7:00 p.m. EDT Thursday as part of the website's Ask Me Anything series. SpaceX CEO Elon Musk did Ask Me Anything in January (http://spacenews.com/elon-musks-ask-me-anything-qa-just-the-space-parts/).
Below is a primer of what we already know about the new system

What will the new system be called?
Bruno refers to the new rocket as the Next Generation Launch System or NGLS, but the formal name of the rocket has not yet been decided. The company has received about 300 suggestions for names fr om ULA employees. That list will be winnowed down and users online will be able to vote for a winner, which will be announced at Space Symposium the week of April 13.

What engines will NGLS use?
Bruno has said ULA is planning on using the BE-4, which is being developed by Blue Origin of Kent, Washington, in partnership with ULA, as the main engine.
If that engine falls behind in development, ULA has a backup plan and could use the AR-1 proposed by Aerojet Rocketdyne. ULA expects to decide in 2016 or 2017 which of the two engines to continue to develop, Bruno has said.

What's the latest on the BE-4?
Blue Origin, founded by Jeff Bezos, is notoriously secretive. In January, Bruno tweeted that "Blue Origin just finished a very successful powerpack test series at subscale."

What's the latest on the upper stage?
This is one area Bruno has kept close to the vest. "We have very exciting plans for the upper stage," he said on Twitter. ULA has long worked with XCOR on a liquid-hydrogen concept (http://www.xcor.com/press/2014/14-11-20_XCOR_announces_ULA_milestone.html). ULA is also working with Aerojet on an upper stage engine, Bruno confirmed. But in a recent interview with SpaceNews he also said other companies are involved in upper stage work.

What about the rest of the rocket?
Bruno told spaceflightinsider.com (http://www.spaceflightinsider.com/organizations/ula/insider-interview-united-launch-alliances-tory-bruno-next-generation-launch-system/) that ULA is developing the first stage, followed by the upper stage and then other subystems. "We have just started wrapping up some of those trades," he said.

When will NGLS launch?
Bruno has said repeatedly the first flight is expected in 2019 if all goes as planned. The certification necessary to launch Air Force satellites would take several years.

Where will NGLS launch?
ULA's plan is to downsize from the five launch pads it maintains between Cape Canaveral Air Force Station in Florida and Vandenberg Air Force Base in California to just one pad at each location. Bruno said the company is still completing the trade studies on the infrastructure it would need, but has informed the Air Force of its long term plans.

Wh ere will ULA build NGLS?
Not clear. But Bruno told the Decatur Daily (http://www.decaturdaily.com/news/ula-s-ceo-talks-challenges-engine-plant-plans-for-decatur/article_8ba49046-af4a-11e4-97ef-ff58591d43fc.html) that "Blue Origin is off right now with our team doing studies ... on wh ere that facility should be, and I can tell you that Alabama and certainly the Decatur area is within the (area) that's being looked at right now. But I don't know what the answer will be."

Who is paying for NGLS-related development activities?
Bruno told SpaceNews that between Aerojet-Rocketdyne, Blue Origin and ULA, the three companies have "identified" $1 billion in private investment.

Will NGLS replace the company's current rockets, the Atlas 5 and Delta 4?
Eventually, yes. ULA hopes to phase out the Atlas 5, in large part, because of a Russian engine known as the RD-180 that powers the rocket's first stage.
The company also has told the Air Force it plans to phase out all but the heavy-lift version of its Delta 4  (http://spacenews.com/everything-we-know-about-ulas-next-rocket/%28http://spacenews.com/ula-targets-2018-for-delta-4-phase-out-seeks-relaxation-of-rd-180-ban/#sthash.d14vBpxv.dpuf)rocket as early as 2018 and will continue building the Delta 4 Heavy as long as its Air Force customer desires.

ЦитатаReusable rocket elements will likely be part of the Next Generation Launch System (NGLS) being unveiled by United Launch Alliance (ULA) at the 31st National Space Symposium in Colorado Springs April 13-16.



The NGLS will mark the first major challenge to SpaceX reusable Falcon rocket development and could involve the downrange recovery and reuse of engines alone, as opposed to the SpaceX design that uses 30 percent of its propellant load to flyback the entire first stage to the launch site.

The NGLS objective to completely replace the Atlas-V and Delta-IV designs in the coming years is driving the development of three new U.S. liquid rocket engines to serve all the missions envisioned "from LEO to Pluto", said Tory Bruno, ULA president and chief executive officer.


NGLS возможно будет частично многоразовой с повторным использованием двигателей. 

ЦитатаThe current cost of an Atlas-V launch is $164 million, while a Delta-IV Heavy costs $389 million.

Eagle? Freedom? GalaxyOne? United Launch Alliance wants public input in the naming of a next-generation launcher designed to replace the historic Atlas and Delta rocket lines in the 2020s.
The top three finalists were sel ected from more than 400 names submitted by ULA's 3,400 employees and space enthusiasts, the company said in a statement.
"ULA's new rocket represents the future of space -- innovative, affordable and reliable," said Tory Bruno, ULA's president and CEO. "More possibilities in space means more possibilities here on earth. This is such a critical time for space travel and exploration and we're excited to bring all of America with us on this journey into the future."
ULA's new rocket -- called the Next Generation Launch System for now -- is scheduled for its first flight in 2019. It will replace the Atlas 5 and Delta 4 rocket families in the early 2020s.
ULA has set up an online poll (https://www.polleverywhere.com/voteula) for voters to share their opinion on which name should be assigned to the new launcher.
Voters can also text 22333 to submit a vote for their favorite name. (Text and data rates may apply)
The following key can be used to text a vote:
• ULA1 for "Eagle"
 • ULA2 for "Freedom"
 • ULA3 for "GalaxyOne"
"Space launch affects everyone, every day, and our goal in letting America name its next rocket is to help all Americans imagine the future of endless possibilities created by affordable space launch," Bruno added.
Bruno says the company plans to retire the Delta 4's medium-lift version when it finishes its already-scheduled launches around 2019. Legislation passed last year prohibits ULA from using Atlas 5 rockets with Russian-made RD-180 engines to launch U.S. national security satellites beyond its current contractual commitments, which run until 2019.
ULA is lobbying for a change in the law to allow Atlas 5s to continue flying with Russian engines while the company's new launcher is being certified to carry expensive U.S. government payloads into space, ensuring competition in the national security launch market with newcomer SpaceX's Falcon 9 and Falcon Heavy rockets.
The Falcon 9 is months away from achieving certification for national security military satellite launches, giving SpaceX access to a large portion of the market. The Falcon Heavy would be needed to launch the military's heavier satellites, and the larger booster has not flown yet.
ULA is working with Blue Origin, a closely-held aerospace firm founded by Amazon.com's Jeff Bezos, to develop a new methane-fueled rocket engine to power the first stage of ULA's new rocket.
Two BE-4 engines designed by Blue Origin would fit on the bottom of the NGLS booster, each generating approximately 550,000 pounds of thrust. Such a larger methane-burning rocket engine has never flown before.
ULA says the BE-4 engine has been in development with commercial funding for three-and-a-half years, giving it a head start over other new propulsion systems. As a backup, ULA has an agreement with experienced propulsion provider Aerojet Rocketdyne for a new kerosene-fueled booster engine in the same class as the BE-4.
Formed in 2006 as a 50-50 joint venture between Boeing and Lockheed Martin, ULA is facing pressure fr om SpaceX to cut costs and stay competitive for lucrative launch contracts with the U.S. military and NASA. ULA says the NGLS design will cost less than the existing Atlas and Delta rockets, and Bruno has hinted that some components could be reusable.
More details on the next-generation launcher, including its design, name, and upper stage engine, will be revealed April 13 at the Space Symposium, an annual space industry convention in Colorado Springs, Colorado.

ЦитатаULA's Next Rocket To Be Named Vulcan
by Mike Gruss (http://spacenews.com/author/mike-gruss/) -- April 13, 2015
 
 
COLORADO SPRINGS , Colorado -- United Launch Alliance's next rocket will be named Vulcan. The name was sel ected from an online vote that ULA said  received more than a million ballots.
"As the company currently responsible for more than 70 percent of the nation's space launches, it is only fitting that America got to name the country's rocket of the future," Tory Bruno, ULA's president and chief executive, said April 13 during a press conference coinciding with the start of the 31st Space Symposium.
ULA employees fr om across the United States submitted more than 400 names. ULA opened voting on the vehicle, currently known as the Next Generation Launch System, March 23 and received more than one million votes online through April 6.
"I was astonished at what happened," Bruno said of the number of votes.
The three finalists were apparent before the press conference started. Blue baseball caps embroidered with the names Vulcan, Zeus and Galaxy One made clear that Eagle and Freedom hadn't made the cut.

ULA is developing the Vulcan rocket  to replace the Atlas 5 and the Delta 4 launch vehicles around the end of the decade.
ULA is working with Blue Origin, Amazon.com (http://amazon.com/) founder Jeff Bezos' secretive space company, on the methane-fueled BE-4 engine to replace the reliable-but-Russian RD-180 engines that have successfully powered 52 Atlas 5 launches for the U.S. government and a small handful of commercial customers since 2002. Congress, however, has enacted a ban on using RD-180 engines for national security missions that is set to take effect in 2019 barring legislative relief.

United Launch Alliance is expected to reveal its design for a next generation satellite launcher Monday, outlining a 20-year roadmap to develop a new methane-powered first stage booster, an advanced space tug and a reusable rocket engine.
The launch company, formed in 2006 by merging the rocket divisions of Boeing and Lockheed Martin, will make the announcement at the Space Symposium, an annual space industry conference in Colorado Springs, Colorado.
ULA plans to retire its basic Boeing-developed Delta 4 rocket by the end of the decade, and then stop flying the Lockheed Martin-designed Atlas 5 booster some time in the 2020s. The shakeup of ULA's rocket line comes with competitive pressure ratcheting up from SpaceX, which says it can launch the U.S. military's satellites at less cost than ULA.
Changes in the geopolitical landscape also forced ULA's hand. The Atlas 5's Russian-made RD-180 main engine became part of a war of words between Russia and the United States last year, when the U.S. government instituted sanctions against Russia following its annexation of Crimea.
Dmitry Rogozin, Russia's deputy prime minister, responded by saying that RD-180 engine exports to the United States could be cut off, but the threat has been empty so far. RD-180 engines are still being delivered to the ULA, officials said.
But the diplomatic spat triggered legislation passed by Congress in December that outlawed buying new Russian rocket engines to launch the Pentagon's most critical space missions, putting the Atlas 5's future in jeopardy and leading ULA to fast-track the design of a replacement U.S. launcher.
The company's Next Generation Launch System will also get a new name Monday after employees and space enthusiasts cast more than a million votes in an online poll.
Tory Bruno, ULA's president and chief executive, said in an interview last week that Monday's announcement will set out the firm's technology roadmap through 2035. Other details, such as which launch pads the new rocket will use, are expected to be announced at a later date.
The design of the new rocket's first stage booster is progressing on pace for a first launch as soon as 2019, he said. It will likely be powered by two BE-4 rocket engines under development by Blue Origin, a start-up space company established by Amazon.com founder Jeff Bezos.
The BE-4 engine will burn a mixture of methane and liquid oxygen, and two of the engines will generate 1.1 million pounds of thrust at full throttle, according to Blue Origin.
ULA has a contract with Aerojet Rocketdyne, builder of a line of rocket engines dating to the dawn of the Space Age, to continue designing its own U.S-built kerosene-fueled engine in case Blue Origin runs into trouble.
Bruno said the first launch of the next generation rocket will use the new first stage booster topped with one of ULA's existing upper stages using a hydrogen-burning RL10 engine. A cluster of strap-on boosters could be added to haul more cargo into space, similar to the adjustable configurations used by the existing Atlas 5 and Delta 4 rocket lines.
"We're doing these things kind of one at a time," Bruno said. "I only have enough resources and enough funding, if you will, because we're sort of a traditional business. We have to earn a profit, and then we take money out of the profits to invest. So I can do the new engine and the first stage first, and then I'll do the upper stage second."
The new upper stage will fly with a piston engine designed in partnership between ULA and Roush Fenway Racing, a motorsports enterprise that competes in NASCAR events. The system will generate electricity and pressurize the rocket's fuel tanks, transforming the upper stage into a long-lived space tug that can maneuver in space for several days.

Engineers plan to also phase in the capability to reuse parts of the coming rocket in a bid to cut the cost of launches, but Bruno cautioned ULA is still wary of taking the same approach to reusability as SpaceX, which aims to recover its Falcon 9 rocket boosters intact, refurbish them, and fly them again.
ULA's rocket unveiling in Colorado is scheduled for 4 p.m. EDT (2000 GMT) Monday, a half-hour before SpaceX plans to launch a Falcon 9 rocket from Cape Canaveral with fresh supplies for the International Space Station. Observers may be more interested in the Falcon 9's first stage maneuvers after the liftoff, which will target a vertical descent and landing on a platform stationed in the Atlantic Ocean.
If successful, SpaceX says the landing experiment is just the next step in the road to making the Falcon 9 first stage reusable. Next will come lengthy inspections, ground testing, refurbishment and convincing risk-averse customers the used rocket booster is capable of another launch.
According to Bruno, ULA's internal studies indicate a reused rocket stage must fly up to 15 times to be more economically attractive than flying single-use throwaway rockets.
"When you talk about conventional technologies on a booster like you see other people doing, and being able to recover and reuse that booster 15 times with relatively minimial refurbishmoent costs, that's pretty darn challenging, and maybe not the right place, in our view, to start on that problem," Bruno said.
ULA has a concept to start recycling components of its new rocket, a strategy Bruno terms "smart reuse."
"Our concept for reusability is inside that mathematics and realizes that maybe reusability does not start with entire stages -- that there are things on it that are expensive and not that hard to get back -- and a lot easier to reuse a number of times," Bruno said. "Maybe that's the right way to start approaching reusability."
Bruno hinted in a speech in February at Stanford University that one starting point for ULA's reusability plan could be in the next generation rocket's engines, which could detach from their fuel tanks and descend back to Earth. Blue Origin says its BE-4 engine can be flown multiple times.
The ability to retrieve and refurbish rocket components "does not appear on the first flight of that new NGLS booster," Bruno said. "We add it later, and it's for the same reason I talked about before. We're doing our whole new rocket in a series of serial steps so that we can afford that development cost."
Bruno declined to disclose how much ULA is spending on the new rocket, which is currently an entirely commercial endeavor. ULA, Blue Origin and Aerojet Rocketdyne are spending internal research and development funds on the rocket.
The Defense Department has funding in this year's federal budget to support the new launcher's development, but the Pentagon has not awarded contracts.
Bruno did provide ballpack figures, saying new rocket engines typically cost at least $1 billion to design, test and fly. An all-new launch vehicle may cost $2 billion, he said.
"Our numbers are going to be be different, and I can't talk about how we divide them between ourselves and Blue Origin and ourselves and Aerojet Rocketdyne," Bruno said.
The target price point for the new ULA rocket is about $100 million per "launch service," Bruno said. He said that is about half of the average price of a ULA booster today.
SpaceX advertises its Falcon 9 rocket for $61 million, but Bruno said the base version of ULA's NGLS will lift more cargo into orbit than the Falcon 9. The much larger Falcon Heavy rocket, formed of three Falcon 9 booster cores strapped together, is priced at $90 million, according to SpaceX.
SpaceX president Gwynne Shotwell told a House subcommittee last month that launch prices for U.S. Defense Department missions would be higher due to special technical and mission assurance requirements levied by the Air Force.
Shotwell said a Falcon 9 launch for a U.S. national security payload would likely be priced between $80 million and $90 million, and an Air Force-purchased Falcon Heavy would go for more than $150 million.

В целом при таком консерватизме и может быть даже костности мышления они отстали от SpaceX навсегда. Лично я ожидал от Тони большего, но очевидно зря. Понятно, что на него давит ответственность, а Маску легко обещать. Но тем не менее.

Подписываюсь, как грится, под каждым словом. 

несколько вопросов:

1. Тори упомянул, что возврат двигателей обеспечит "up to 90% first stage cost recovery".  Я так понимаю, это в случае без ТТУ?  ;)   (и вообще, сколько каждая из ТТУшек будет стоить?)

2. Использование такой громоздкой схемы с "hypersonic deceleration shield" опять-таки нужно из-за ТТУ, да? Т.е., они добавляют  delta-v ступени с БЕ-4 настолько, что Спейсовская схема никак не прокатит? (тогда как же центральная core FH обходится без этого?)

3. Нужен ли этот deceleration shield в пусках без ТТУ, (и наоборот - будет ли сделана самая тяжелая версия без всех этих заморочек с возвратом БЕ-4)?

Ага.. Но все равно как-то слишком сложно получается - нужно отстыковать движки от ступени, перевернуться, чтобы щит был внизу, надуть его, затормозить, сдуть щит, потом открыть парашют, и потом надеяться, что вертолет этот блок подхватит как надо...

Такое ощущение, что ЮЛА идею reuseability просто ненавидит, и выбрала такую схему, чтобы наглядно это доказать.   "Ну? Все видели? Фигня какая-то получается, и мы сразу ведь предупреждали!" 

P.S. А ведь еще, получается, им тоже морское судно понадобится, да еще с вертолетной площадкой и палубой, куда можно аккуратно с вертолета блок опустить.  И, в отличии от Маска, который уже начиная с Jason-3 хочет на землю сажать, такая морока будет у ЮЛА всегда, поскольку блок этот к земле никак не подогнать.

ЦитатаULA's Vulcan Rocket To be Rolled out in Stages
by Mike Gruss (http://spacenews.com/author/mike-gruss/) -- April 13, 2015

ULA CEO Tory Bruno unveils the company's proposed Vulcan rocket during an April 13 press conference at the Space Symposium in Colorado Springs. Credit: Tom Kimmell for Space Foundation.
 
COLORADO SPRINGS, Colo. -- United Launch Alliance unveiled an incremental approach to replace its workhorse Atlas 5 rocket, an ambitious path forward that ultimately would include a new second stage and, later, reusable first-stage engines that would be captured midair by helicopter after each mission.
The plan would provide a competitive alternative to SpaceX's low-cost Falcon 9 rocket but entails risk for ULA as it funds a significant development program for as many as nine years as its competition gains momentum.
Tory Bruno, ULA's president and chief executive, declined to detail the company's exact investment in the project but suggested that new rockets typically cost about $2 billion to develop, including the main engine. During an April 13 press conference on the eve the 31st Space Symposium here, he said that cost would be borne by ULA and its strategic partners, but that the company would not turn down government money if that becomes available.
The first step in the developing the newly named Vulcan rocket is developing a new first stage featuring the methane-fueled BE-4 engine by Blue Origin of Kent, Washington. ULA is also working with Aerojet Rocketdyne on the AR-1 engine, in case the BE-4 runs into delays.
The program is driven by the requirement to replace the Russian-built RD-180 engine that serves as the main powerplant for ULA's Atlas 5. Congress imposed a ban on future use of Russian engines in U.S. national security missions following Russia's annexation of Crimea from Ukraine last year.
In addition to the new engine, the Vulcan's first stage would feature a stretch version of the tank used on ULA's Delta 4 rocket, which the company is phasing out in 2018 because it is too expensive. The second stage of the initial Vulcan version, slated to debut around 2019, would feature the same Centaur upper stage and fairing now used on the Atlas 5, Bruno said.
The Vulcan could be augmented by up to six solid rocket boosters, giving it greater lift capability than the largest version of the Atlas 5 but not as much as the Delta 4 Heavy, which features three core stages in a side-by-side configuration. Bruno said he plans to issue a request for proposals within the next 12 months for the large boosters, which would likely be built by either Orbital ATK or Aerojet Rocketdyne.
ULA told the Air Force in February it plans to start two separate U.S. Air Force certification processes for the rocket later this year, one with the BE-4 and one with the AR-1. Certification is required for the Vulcan to carry U.S. national security payloads.
Bruno said ULA's first choice is the BE-4 but that it continues to fund the AR-1 work as a backup option, and that ULA will make a final decision on in 2016.
The next step in Vulcan's evolution is a new upper stage known as the Advanced Cryogenic Evolved Stage, or ACES, which could be able to operate in space for weeks at a time, ULA officials said. This would open up a whole new range of missions to the Vulcan, ULA officials said.
The ACES stage would have anywhere from one to four cryogenic engines, depending on the mission. The candidate engines are: a new variant of the RL10 produced by Aerojet Rocketdyne and currently used on both the Atlas 5 and Delta 4; Blue Origin's BE-3; and an engine being jointly developed with XCOR aerospace.
ULA will sel ect the engine for the ACES stage in the next few years, Bruno said.
ACES, ULA officials said, would have "almost unlimited burns" and extend on-orbit operating time from hours to weeks.  The liquid-oxygen/liquid hydrogen-fueled stage would recycle excess fuel for attitude control and other purposes, ULA officials said.

Aerial Recovery
Ultimately, ULA plans to reuse the Vulcan's first stage engines through a process called Sensible Modular Autonomous Return Technology. After first-stage burnout, the two engines would be severed fr om the tank and deploy an inflatable heat shield to slow their re-entry. They then would deploy steerable parachutes, which would slow their descent enough so they could be recovered in mid-air by a helicopter.
Once recovered, the engines would be re-certified and used again. The reusability feature is especially important as engines make up about two-thirds of the rocket's cost, ULA officials said. Bruno has said he hopes to drive the cost of the standard Vulcan rocket down to about $100 million.
ULA hopes to introduce the ACES upper stage in 2023 and the reusable first stage in 2024, Bruno said.

Коротко:
Первая ступень - до шести ТТУ от Орбитал АТК, или Аэроджет с увеличенной тягой.

Вторая ступень - удлинённые баки от Дельты-4 с двумя BE-4, или в случае неудачи с двумя AR-1 общей тягой 500 тс. Впоследствии двигатели будут спасать в баллистической капсуле с вертолётным подхватом.

Третья ступень - на начальном этапе новая версия Центавра, а в последствии новая ступень ACES с одним-четырьмя RL10, BE-3 или XCOR. Кроме того поршневая помпа, использующая испаряющееся топливо для производства электроэнергии и наддува баков. Это позволит ACES работать до недели на орбите.

ЦитатаNext Generation Launch System


With the introduction of the Vulcan, ULA's next generation launch system (NGLS), ULA is transforming the future of space launch -- making it more affordable, accessible, and commercialized -- and innovating to develop solutions to the nation's most critical need: reliable access to space.

Unleashing Mankind's Potential in Space
More capabilities in space mean more capabilities here on Earth. By making it more affordable
to conduct launches, Vulcan will open up brand new opportunities for the nation's use of space.

Simple and Affordable
The NGLS offers our customers unprecedented flexibility in a single system. From low Earth orbit (LEO) to Pluto, the single-core NGLS does it all. This simple design is more cost-efficient for all customers, whether defense and national security, NASA science and human spaceflight, or commercial.

American Power
The NGLS will have an American engine, will offer the best value and with the introduction of the Advanced Cryogenic Evolved Stage (ACES) it will have greater capability than any other rocket on the market.

In step one, with a planned initial launch capability in 2019, Vulcan will exceed the capability of
Atlas V, serving the vast majority of our customers' mission needs. Step one of the NGLS consists of single booster stage, the high-energy Centaur second stage and either a 4-meter or 5-meter-diameter payload fairing. Up to four solid rocket boosters (SRBs) augment the lift off power of the 4-meter configuration, while up to six SRBs can be added to the 5-meter.

In step two, the Centaur second stage will be replaced by the more powerful ACES in 2023. With the addition of ACES, Vulcan will achieve the current capability of the Delta IV Heavy, which carries the largest payloads for our most critical customers.

Как я понял, речь идет о "booster and propulsion cost", т.е., ступени и ДУ. Если вы для себя перевели это как-то иначе, то поясните, а то фразу "снижение на 90% стоимости ДУ" можно понимать как угодно, вплоть до того, что после первого использования ценность выловленного блока снижается на 90 процентов.

Интересно получается, учитывая что будут использоваться баки от Дельты мне казалось что под вулкан переделают стартовые площадки от Дельты 4, но  если Вулкан не сможет заменить Дельту Хеви, то какое-то время они должны будут существовать вместе, ну и об отказе от Атласа до полноценной эксплуатации Вулкана речи тоже не идет. Это что же получается, они новую площадку строить под Вулкан делать будут?
И получается, что ULA урезает себе возможности по выводу, ведь с окончанием запусков Дельты 2, легкой ракеты у ULA не будет, да и возможности Дельты хеви (кстати неизвестно какой версии) Вулкан закроет лишь на 2-м этапе, а ведь были в заначке и варианты Атлас Хеви и Дельты Хеви с ускорителями. Получается ULA смирилась с тем, что легкий класс отойдет Орбитал, а сверхтяжелый SpaceX.

И еще один непонятный момент, зачем нужен 4-х двигательный ACES, ведь Centaur-5-DEC не летал ни разу, а у DCSS 2-х двигательной опции вообще нет. Разве что для того чтобы NASA предложить в качестве EUS.

DCSS как я понимаю ULA хоронит, хотя и впарили его NASA.
Вот интересно, а обтекатели от Дельты останутся или только от Атласа будут?

CAPE CANAVERAL -- The heavy-lift version of the United Launch Alliance's new Vulcan rocket will sell for half the price of today's Delta 4-Heavy and a third of the price tag for the previous Titan 4, while offering a substantial increase in performance for the nation's largest defense spacecraft.
"Well below $200 million. Value is unlimited on-orbit operations," George Sowers, ULA's vice president of strategic architecture and advanced programs, told a reddit.com chat Wednesday.
The Delta 4-Heavy has flown eight times, most recently with NASA's Orion capsule last December. But the bread and butter for the launcher is classified National Reconnaissance Office payloads -- massive eavesdropping platforms placed directly into geosynchronous orbit and optical spy satellites launched from the West Coast.
ULA boss Tory Bruno announced the company plans to retire the medium-class, single-core Delta 4-Medium and -Medium+ configurations in 2019. The Delta 4-Heavy will live on as long as the Air Force and NRO need it.
"I have personally communicated to the Air Force and NRO that we will keep the Delta 4-Heavy available until they are able to gracefully transition to the Vulcan. I expect that to be out in the 2023-24 timeframe. But it'll be up to them," Bruno says.
By that time, the new Vulcan rocket's first stage will be four-to-five years old and certified by the Air Force to launch the country's security spacecraft.
"Yes, we've already started. You begin the certification process by writing a letter to the Air Force and telling them 'I'm going to have a new rocket,'" Bruno said of certification.
"The fundamental difference in our approach to certification is we intend to continue our policy of transparency with the government. We've invited them now, literally when we first began this path, to engage with us, to attend design reviews, to participate and have that visibility as we move through the development process.
"Instead of having finished all our work without letting the government participate and backing up the semi-truck and dumping all the qual testing on 'em and all the drawings and all the processes and plans, we're going to bring them along all the way."
Certification will allow the initial Vulcan configurations to launch Air Force and NRO satellites in the medium-class market. The Vulcan's new first stage will be outfitted with a Blue Origin BE-4 main engine and up to six solid-propellant boosters for added lift. The existing Centaur will be the upper stage.
Step No. 2 in the development process of the new rocket will introduce the new Advanced Cryogenic Evolved Stage, or ACES, to the Vulcan first stage in 2023. It will increase performance to Delta 4-Heavy levels and beyond. A subsequent certification of the new upper stage will be required, too.
The third development step will bring reusability in the form of mid-air recovery of the discarded main engines. The powerplants will be brought back to land, refurbished, certified for reflight and plugged into the next booster in the factory, Bruno said.
"I don't think the business case closes for full-stage re-use," Sowers told his reddit.com audience."I don't think the business case closes for anyone."
ULA officials are confident they can compete in the marketplace with the reduced costs of Vulcan, which has an entry-level price of $100 million before reusability kicks in. And the ACES and Integrated Vehicle Fluid engine aboard the new upper stage will allow it to operate for weeks instead of mere hours for value added capabilities.
It'll all be accomplished using single-core Vulcans, unlike the triple-barreled Delta 4-Heavy.
 "Yes. LEO to Pluto with a single stick," Sowers said.

CAPE CANAVERAL -- United Launch Alliance revealed its visionary approach to space exploration in the next decade courtesy of the Vulcan rocket's new, long-duration upper stage that can be fitted with as many as four engines to perform cargo resupply and astronaut transportation to far-flung destinations.
"This is the real game-changer," Tory Bruno, the CEO and president of ULA, said in unveiling the company's next-generation rocket on Monday.
It all starts with what Bruno calls "distributed lift" to split the launches of supplies and people into two flights without needing a large rocket. That's when the Advanced Cryogenic Evolved Upper Stage, or ACES, takes over.
"Today, the concept for launching objects, for satellites, for missions into space is highly constrained. It's trapped into the notion that the spacecraft has to be completely self-contained, physically. If it's a satellite, it has to fit in the nose fairing. If it's a capsule, it has to fit inside that capsule envelope. And once it goes up, there's no opportunity to meaningfully, physically interact with it. That upper stage shatters that limitation and opens up this possibility of distributed lift.
"We can take our first launch, big fuel tanks, supplies, food, water, if it's a manned mission. And the next mission will bring up the spacecraft or the astronauts in their capsule. With this advanced upper stage, which can fly around for weeks, it's up there waiting, we can put these pieces together, and outside the deep part of Earth's gravity well with that much impulse and propellant, we can do anything.
"We can go out and tap the resources that are in space. We can asteroid mine, we can build the infrastructure required for a real and permanent human presence. Fuel depots, water depots, commercial human habitats. This is truly a game-changer and I couldn't be more excited about what this will do for the future of space, all enabled by that advanced, high-performance, ultralong-duration upper stage," Bruno said.
(http://spaceflightnow.com/wp-content/uploads/2015/04/NC4_DistributedLift413201561450PM63.jpg)
The ACES stage is scheduled to debut in 2023, a year before distributed lift, which is the fourth and final development step to bring the full potential of the Vulcan rocket system.
"We can do anything you might imagine a permanent presence, a true commercial exploitation of space would require. All of that infrastructure that's truly required to see the potential of space can now be put together," Bruno said.
The existing high-energy Centaur upper stage will fly on Vulcan in the earliest years starting in 2019. The new upper stage will allow the new rocket to surpass the capability of the Delta 4-Heavy for U.S. National Reconnaissance Office spy satellites.
The engines will be manufactured by either Aerojet Rocketdyne, Blue Origin or XCOR. A decision on which supplier to use will come later. The stage can use between one and four powerplants, carry three times more propellant than Centaur, burning liquid hydrogen and liquid oxygen, and operate in space for weeks instead of mere hours.
"The ACES is a concept we've been working on for quite a few years," said George Sowers, ULA's vice president of strategic architecture and advanced programs.
"It is a LOX/hydrogen upper stage, high-energy, a balloon-tank, pressurize-stabilized tank, thin-walled stainless steel, a very efficient design. The Integrated Vehicle Fluids is really the key to expanding the capabilities of the stage."
ULA is building the IVF with Roush, the NASCAR team. The internal combustion engine will take waste propellants and recycle them to repressurize the tanks, to generate electrical power and to provide attitude control thrust. It eliminated the need for helium and hydrazine to be carried on the stage versus today's stages.
Cost to develop the Vulcan rocket, though, is being kept a secret. "We are not talking about how much it costs. We are paying for it, ourselves, ULA," Bruno added.

ЦитатаULA sees clean handover of Boeing crew launches to Vulcan rocket       
Posted on April 18, 2015 by Justin Ray (http://spaceflightnow.com/author/justin-sfn-ray/)
(http://spaceflightnow.com/wp-content/uploads/2015/04/CciCap-Render-2.jpg)

CAPE CANAVERAL -- United Launch Alliance vows a "seamless" switch from the Atlas 5 to the new Vulcan rocket in launches of Boeing's astronaut taxis.
ULA is the launch provider of Boeing's CST-100 capsule under NASA's commercial crew program that will start ferrying astronauts to the International Space Station from U.S. soil in 2017.
On Monday, ULA unveiled its lower-cost, reusable Vulcan rocket family that will begin flying in 2019. Due to budget constraints, the company will develop the rocket in steps, with the first stage coming initially.
The Vulcan to fly for the first four years will be powered by a pair of Blue Origin BE-4 methane main engines and up to six strap-on solid rocket boosters. The existing Centaur upper stage will be used until a new, advanced upper stage can be fielded starting in 2023, which is Step 2 of development.
"Because the front end of the rocket, the top half of it is the same as today's Atlas, at least in Step 1 (of development), all of the interfaces for the CST-100 at the launch pad and on the rocket are identical for what they are on Atlas," said George Sowers, ULA's vice president of strategic architecture and advanced programs.
"Any of the crew providers that are currently integrated to Atlas would have a seamless transition to this vehicle at a lower cost," he added.
The Vulcan-Centaur, like the Atlas 5, will require a 422 vehicle variant, with two strap-on solid rocket boosters and a dual-engine Centaur upper stage to put the CST-100 capsule into low-Earth orbit.
But the addition of the new, high-performance Advanced Cryogenic Evolved Stage replacing Centaur will eliminate the need for solid rockets, allowing CST-100 to fly on the entry-level Vulcan-ACES vehicle.
Atlas 5 is being human-rated and Vulcan will be from the start.
"While our baseline launch vehicle design for the CST-100 is for the Atlas 5, from the onset we've designed our CST-100 to be launch vehicle agnostic, which means we can launch on any vehicle after some modifications. We will continue to work closely with ULA on their plans for future launch vehicles," said Boeing spokesman Adam Morgan.
ULA chief Tory Bruno says it will be up to Boeing when the transition from Atlas to Vulcan occurs.
At ULA's production factory in Decatur, Alabama, work has begun producing the first two Atlas rockets that will carry the Boeing capsules on test flights in 2017.
"There's two significant changes to the rocket that we're talking about. We'll go to a two RL10 engine version of the Centaur and we're doing some structural interfaces for the capsule," Bruno said.
"Everything else on Atlas is essentially identical. It's really a matter of going through the process of human-rating all of that existing rocketry to make sure it has the margins and pedigree and everything that goes along with that to be certified for human spaceflight."
The CST-100's first two space missions will see an unpiloted test flight in April 2017 and a demo mission with a two-person crew in July 2017, leading to NASA astronaut taxi missions to the International Space Station beginning at the end of 2017.
Those first two launches aboard Atlas 5 carry the tailnumbers AV-073 and AV-080.
"The last time we were at this stage of development for a human spacecraft was in the 1970s when we were building the shuttle," said former astronaut Chris Ferguson, now Boeing's director of Crew and Mission Systems for the company's commercial crew division.
"I have Apollo manuals on my desk -- not to copy designs but to understand how they did it and to validate the decisions we've made with regard to provisions for the crew, what kind of spacesuits they wear, what kind of seats they sit in, and why they sit that way. Engineers put an enormous amount of thought into many low-level designs decades ago, but now we're trying to recreate the "why" behind all that. It's a little intimidating, but it's fun. You learn why the space program took the shape it is today over five decades ago."

Before decade is out all US military satellites may be grounded  
 
By Mark Albrecht, PhD and USAF Maj. Gen. Howard Mitchell (ret.)
 
Today, the launch infrastructure of the United States National Security Space (NSS) -- comprised of the Department of Defense (DoD), the Services and the Intelligence Community (IC) -- is teetering on the edge of a gap in capability which, in less than five years, could mean no capacity to launch the bulk of critical national security missions for as long as ten years. 
We are close to retiring our existing fleet of launch vehicles without new ones to assure our access to space. Since 1999 we have had an unprecedented string of successful NSS launches, over 90 as of this writing, hoisting payloads fr om GPS satellites that provide critical position, navigation and timing capability to U.S. forces worldwide, to military communications satellites that provide high capacity global military communications for command and control of air, land and naval forces, as well as for command and control of Unmanned Aerial Vehicles (UAVs) and drones around the world, to critical intelligence, surveillance and reconnaissance satellites that provide the national command authority eyes and ears in the sky.  America's enemies operate with the certain knowledge that they have nowhere to run, nowhere to hide fr om American reach.  And assured access to space is the key.
We have accomplished these successes and this remarkable record primarily utilizing two launch vehicles, the Atlas V and the Delta IV.   Both were designed in the 1990's and have been operational since the end of the century.  Both are in their prime of service, yet we are abandoning them in as few as five years and have no high probability plan for their replacement. The simple fact is, we have done this to ourselves.
The Atlas V is planned for retirement as early as 2017 because the Congress has mandated that, as punishment for Russian bellicosity in the Ukraine and Crimea, the Department of Defense no longer use Russian rocket engines for the launch of national security missions.
The Delta IV is planned for retirement in 2017 because it is simply too expensive to compete in the commercial marketplace, or even to compete with new entrants to the government launch market.  Only the 'heavy' version of the Delta IV remains in service because this behemoth alone can lift the one or two largest and bulkiest payloads for the National Reconnaissance Office.
Which brings us to SpaceX.  Its Falcon 9 launcher was developed by a combination of private and unencumbered government funds primarily for the commercial marketplace and resupply and human spaceflight to and from the space station. The problem is, the DoD has yet to certify the Falcon 9 ready to launch NSS payloads.
So what is the plan for NSS launches in just five years?  Seems like everyone has a different answer and none of them are sure bets. 
United Launch Alliance, the joint venture that currently offers Atlas V and Delta IV says it is going to build a new launch vehicle powered by a completely new rocket engine.  It will cost between $1.5B and $2.5B.  Problem is, no one has come forward and explained wh ere the money will come from and the joint venture has little or no resources of its own to commit to the program.
SpaceX believes that it's Falcon 9 and derivatives of its current design and a new 'heavy version' of the vehicle will fill the bill by 2018.  Problem is, not even the basic Falcon 9 has been certified as ready to launch NSS payloads and the critical new 'heavy' version doesn't even exist yet.  Certification of the Falcon 9 has taken almost two years and isn't to the finish line yet.
Congress has appropriated funds for the Air Force to develop a high performance liquid oxygen and kerosene engine that could be used on the Atlas V.  Problem is, the Air Force isn't sure how to get this work done in time and isn't sure enough funds are available to accomplish the goal even if it could acquire a suitable substitute.
Some hope this looming gap in the national security launch capability will cause the DoD and the Congress to release constraints on Russian engines, or spend money on a crash program to develop a new launch capability.  Problem is, Congress is skeptical that schedule relief will solve the problem and the Department of Defense doesn't have any money earmarked for a new launch acquisition.
We have been on several important government chartered panels in the past nine months regarding NSS launch.  Each has looked at different aspects of the launch dilemma, all have confirmed the complex and risky situation we have described and sounded the warning horn to all who will listen.
The government needs to take ownership and face this problem head on.  It needs to define the end state and show commitment to a credible, achievable and affordable solution for NSS launch in the 2020s and it needs to commit the necessary resources to achieve the desired outcome.  It has been said that today's American military is 'space based.'  It is our duty to make sure we can support our forces in the next decade with assured access to space. 

Albrecht was executive secretary of the National Space Council wh ere he served as President George H.W. Bush's principal adviser on the U.S. Space Program. He was also president of Lockheed Martin's International Launch Services company.  Mitchell was director of Operations at Air Force Space Command and director of the Office of Space Launch for the  National Reconnaissance Office.

ЦитатаDeveloped for Blue Origin's planned Orbital Vehicle, the BE-4 (designating the fourth Blue engine) is an oxygen-rich, staged combustion, single-shaft rocket engine designed to burn liquefied natural gas (LNG).
"Liquefied natural gas is almost 100% methane; it has a few other hydrocarbons in it," says Bezos, who appeared with Bruno at a Washington press conference to announce the deal. "We're designing the engine to run on liquefied natural gas or methane. They're both roughly the same density, but methane is considerably more expensive because to remove the last little bit of other kinds of hydrocarbons is costly. Cost/operability is what drives us designing the engine."

 [url=http://www.ulalaunch.com/]United Launch Alliance[/url] (ULA), the company that makes rockets for NASA and the U.S. Air Force, plans to 3D print more than 100 flight-ready components for its next-gen model of rocket.
 That rocket, the Vulcan, was announced just last week and will combine the best attributes of the company's current Atlas- and Delta-model rockets. The Vulcan also offers a unique opportunity to infuse 3D printing of parts from the very beginning of the design concept, according to Greg Arend, program manager for additive manufacturing at ULA.
 "We have a long list of [parts] candidates to evaluate -- over 100 polymer parts we're considering and another 50 or so metal parts we're considering," Arend said. The Vulcan is expected to launch sometime in 2019.
 ULA is a leading rocket launch services company in the U.S. and it has supported America's presence in space for more than 50 years.
 On the lower-end, ULA's rockets cost $165 million, and they must propel into space billion-dollar satellites weighing more than 60,000 pounds.
 Arend said the 3D printers could save his company as much as $1 million per year in parts manufacturing costs.

ULA

 ULA has printed a new Environmental Control System for its Atlas V rocket. The ECS assembly had previously contained 140 parts that were made by third party suppliers, but ULA was able to reduce the parts to just 16, resulting in a 57% part-cost reduction.
 Flight-ready parts are expensive to make, both in terms of lead-time and manufacturing. With traditional manufacturing, a contract must be hammered out for a third-party supplier to create a part to ULA's specifications. If there's a problem with the part, it must be sent back to the supplier and retooled. Third-party suppliers must also meet deadlines; sometimes they do, sometimes they don't.
 With 3D printing, ULA maintains internal quality control that  doesn't have to be "held hostage by other companies who have other priorities," Arend said. "We can control our destiny better by bringing that work in house."
 ULA has used fused deposition modeling (FDM) 3D printing for making tools in the past, including clearance gauges, printed drill-hole guides and molds that shape liquid insulation as it expands and hardens.
 With two new 3D printers, the company, which launches 12 rockets each year, is also hoping to use 3D printing for a more traditional role -- rapid prototyping of parts. Rapid prototyping allows an engineer to actually hold a part and test its fit and functionality prior to making the production part or ordering it from a supplier.
 ULA purchased two new Fortus 900mc 3D Production Systems from Stratasys. The machines will initially be used to make a new Environmental Control System (ECS) duct on the current the Atlas V rocket (http://www.ulalaunch.com/products_atlasv.aspx), which will launch with the new 3D component in 2016.
 The ECS duct is used pre-launch to deliver nitrogen cooling to sensitive electronic components within the rocket booster.

 The previous design for the ECS duct assembly contained 140 parts. But by modifying the design using FDM 3D Printing technology, ULA consolidated the number of parts to only 16. This significantly reduces installation time and results in a 57% part-cost reduction.
 "It's about as demanding an application as you can get," Rich Garrity, general manager of Stratasys' Vertical Solutions Unit, said in a statement. "Rockets must endure pressure, G-force, speed, vibration, heat and extreme cold."
 ULA sel ected Stratasys' ULTEM 9085 FDM thermoplastic material to produce the high-performance parts.
 The Stratasys Fortus 900mc 3D printers do not print with metal. ULA is evaluating other 3D printers for those parts, Arend said.
 "ULTEM 9085 has great strength properties over a wide temperature range," Arend said. "We have done testing to show that it is very capable of withstanding temperatures fr om cryogenic all the way up to extreme heat. And it's tough enough to handle the vibration and stress of lift off and flight. We're very satisfied with its performance."

ЦитатаEvolution of a Plan | ULA Execs Spell Out Logic Behind Vulcan Design Choices
by Mike Gruss (http://spacenews.com/author/mike-gruss/) -- April 24, 2015

On his first day as United Launch Alliance's president and chief executive, Tory Bruno (above) had a stark message for his new board of directors, composed of senior Boeing and Lockheed Martin executives: ULA needed a new engine, and needed it quickly. Credit: SpaceNews/Tom Kimmell  
 
COLORADO SPRINGS, Colo. -- By the time United Launch Alliance's corporate parents, Boeing and Lockheed Martin, tapped Tory Bruno to take over the government launch services provider last July, the handwriting was on the wall: ULA was going to need a new rocket if it hoped to remain in business for the long haul.
Congress by that time had drafted legislation banning future use of the Russian-built RD-180 main engine that powers ULA's main workhorse, the Atlas 5. The measure, prompted by Russia's annexation of Crimea from Ukraine, would become law by the end of the year.
Moreover, ULA soon would be facing stiff competition in its core national security market from Hawthorne, California-based SpaceX, the hard-charging rocket-making venture founded by tech billionaire Elon Musk.
By the time he officially replaced Michael Gass as ULA's president and chief executive on Aug. 12, Bruno had done his homework. On his first day, he had a stark message for his new board of directors, composed of senior Boeing and Lockheed Martin executives: ULA needed a new engine, and needed it quickly.

It was not exactly a revelation. ULA in June announced it had put several companies under contract to study new engine concepts. Those companies, not named at the time, included Blue Origin, the secretive rocket venture owned by Amazon.com founder Jeff Bezos, and U.S. propulsion stalwart Aerojet Rocketdyne, which had been developing a kerosene-fueled, 500,000-pound-thrust concept known as AR-1.
But that meeting set into motion the sequence of events that culminated in ULA's April 13 announcement (http://spacenews.com/ulas-vulcan-rocket-to-be-rolled-out-in-stages/) that it would develop a rocket dubbed Vulcan using an incremental approach whose first iteration essentially is an Atlas 5 outfitted with a new first stage. The rocket, which has yet to be approved by ULA's board, is slated to debut in 2019.
During the meeting, Bruno walked through the alternatives Denver-based ULA had studied to date, including the AR-1 and Blue Origin's BE-4, the latter already being the favorite of one of his key deputies, George Sowers, ULA vice president for advanced concepts and technologies.
The board, which is chaired in turns by Rick Ambrose, executive vice president of Denver-based Lockheed Martin Space Systems, and Craig Cooning, president of Boeing Network and Space Systems of Arlington, Virginia, responded by telling Bruno to thoroughly examine every possible alternative.
In the following weeks, ULA executives examined about a dozen such concepts, including solid boosters, a Ukrainian option that was deemed too risky because of the proximity of its manufacturer to Russia's border, and ideas from companies that Bruno said he had never heard of. ULA also considered a domestically produced RD-180, the possibility of which helped convince Pentagon skeptics in the 1990s that it was acceptable to have a mainstay military satellite launcher powered by a Russian-heritage engine.

Then there was the question of whether ULA's other rocket, the Delta 4, could be transformed into a viable competitor to SpaceX's Falcon 9 rocket. The Delta 4 is powered by an Aerojet Rocketdyne-built main engine and is the only launcher in the U.S. fleet with a certified heavy-lift version, needed to launch some of the Defense Department's most critical and expensive satellites.
"We wanted to cast a wide net because picking that engine path was just extremely important to the future of the company," Bruno said in an April 15 interview.
About one month after the meeting, on Sept. 16, ULA unveiled its choice: Blue Origin's BE-4. The selection, announced by Bruno and Bezos in a Washington press conference, was a stunner, especially for Sacramento, California-based Aerojet Rocketdyne, which had billed the AR-1 as a relatively straightforward replacement for the kerosene-fueled RD-180.
ULA executives liked the AR-1, but "it wasn't clear how that engine could be funded," Bruno said, notwithstanding the fact that Congress by that time appeared ready to appropriate substantial money for work on an RD-180 replacement. "Even though it was a kerosene and a closer match to the RD-180 -- it didn't appear to have a timely availability because it hadn't yet started and it had no funding," he said.
Aerojet disputes that assertion, saying key AR-1 components and technologies have been in development for some time with a combination of government and corporate funding.
ULA officials nonetheless viewed the BE-4 as well ahead of the AR-1 in development, and the combination of that and the fact that it was funded by Blue Origin made it the clear choice. "We said it's Blue. It's clearly Blue. By a far margin," Bruno said.
  (http://spacenews.com/wp-content/uploads/2015/04/BE4_testing-ULA.jpg)
On Sept. 16, United Launch Alliance unveiled its engine choice: Blue Origin's BE-4 (above). "We said it's Blue. It's clearly Blue. By a far margin," ULA Chief Executive Tory Bruno said.
The decision still puzzles some industry observers, who note that BE-4 is powered by a different fuel than the RD-180 and thus will require developing a new first stage.
"We did enough work to know if you pick a Blue engine it's a liquid-natural-gas fuel," Sowers said. "The basic architecture was part of the trade."
In the wake of the decision, Aerojet stepped up its internal investment in the AR-1, although company officials concede that U.S. government funding -- Congress has allocated $220 million this year for engine development work -- will be necessary to complete the project. Aerojet Rocketdyne also made an announcement of its own, saying it was working with ULA on AR-1 development.
  (http://spacenews.com/wp-content/uploads/2015/04/AR1_twin_configuration-Aerojet_Rocketdyne-e1429725929975.jpg)

ULA says it is keeping the AR-1 option alive in case the BE-4 runs into developmental difficulty.
ULA's board, meanwhile, informed of the BE-4 selection, approved three months' worth of investment funding and laid out a series of near-term milestones for ULA to reach.
"When Tory was named CEO, the board was aware of -- and continues to support -- the government's goal of fielding an American-made engine as quickly and affordably as possible," said Robert Sterling, a Boeing spokesman who responded on the board's behalf to SpaceNews questions. "Tory has moved decisively to determine a strategy for supporting that goal and for meeting the government's needs for assured access to space."
Fast forward to ULA's April 13 announcement, in which the company disclosed details about the Vulcan beyond the BE-4-powered first stage. The major elements of this evolution are a new upper stage, to be phased in in 2023, and first-stage engine reusability, to follow in 2024.
Plans for the Advanced Cryogenic Evolved Stage, or ACES, actually predate ULA's 2006 creation -- officials with Atlas 5 developer Lockheed Martin viewed it as the next step in that vehicle's evolution. But with Russia's incursion into Ukraine, "we had to do the [main] booster" first, Sowers said.
Initially, ACES was considered for both the Atlas 5 and Delta 4, but with the emergence of SpaceX as a legitimate rival ULA had to rethink the viability of maintaining two different launchers over the long-term. "You can't carry two systems into a competitive environment," Sowers said.
After internal debate, Atlas won out because of its lower cost.
Unlike the Delta 4, however, there is no Atlas 5 heavy-lift variant. "The solution was to put the bigger upper stage on the Atlas so that gave us the heavy capability," Sowers said.
The ACES-equipped Vulcan, augmented by strap-on boosters, would have 30 percent more lift capacity than the Delta 4 Heavy, currently the largest vehicle in the U.S. fleet, Bruno said.

The Road to Reusability
 The final piece of the publicly announced Vulcan architecture is partial reusability.
ULA had long studied reusability -- in 2008, the company presented a paper at a conference in San Diego called "Partial Rocket Reuse Using Mid-Air Recovery" that appears to be the foundation for the current Vulcan concept. "Using helicopter mid-air recovery as the engine module descends under a parafoil is a low-development-cost approach which brings back the booster engine with exposure to only benign environments," the paper said.
ULA refers to its engine reusability concept as Sensible Modular Autonomous Return Technology. After first-stage burnout, the two BE-4 engines would be severed from the fuel tank and deploy an inflatable heat shield to slow their descent. They then would deploy steerable parachutes, which would further slow their descent so they could be plucked out of midair by helicopter.
The reusability feature is especially important as engines make up about two-thirds of the rocket's cost, ULA officials said.

"I felt it was going to take people a certain amount of time to understand the approach," Bruno said. "We took a radically approach than the other guys."
SpaceX also plans to reuse the first stage of its operational Falcon 9 and planned Falcon Heavy rocket, but its concept has the stages coming in for a powered vertical landing on a platform after launch.
During the interview, Bruno said the Vulcan roadmap actually runs through 2035 and includes several more iterations. Those steps, he said, are less firm than the new engines and reusability concept.
Of course, ULA still must convince skeptics that the Vulcan architecture as outlined April 13 is more than just a paper rocket. The push by ULA and its corporate parents for a relaxation of the RD-180 ban so that the company can continue to use the Atlas 5 -- the Delta 4 is now designated for retirement -- until the Vulcan is ready has only fueled that skepticism.
During Vulcan's unveiling, Bruno said ULA is counting in part on the willingness of Boeing and Lockheed Martin to allow the company to use some of its profits, which currently go to the bottom lines of the corporate parents, to fund the rocket's development.
So far, ULA's board has limited its approval of Vulcan-related investments to quarterly increments. "We have made no long-term commitments on the funding of a new rocket, and are currently assessing all options," said Sterling, the Boeing spokesman. "The board is actively evaluating continued investment in the new rocket engine program and will continue to do so."

ЦитатаFrom Atlas to Vulcan: 34 Years of Rocket Evolution in 1 Image

Tory Bruno, the president and chief executive of United Launch Alliance, tweeted this infographic July 29 depicting the Vulcan rocket's Atlas heritage. Credit: ULA.  
 
Tory Bruno, the president and chief executive of United Launch Alliance, took to Twitter July 29 to discuss the heritage of his company's new rocket, known as Vulcan, and unveil the infographic above.
"An effective way to manage risk is to incrementally add new technologies to an existing platform," Bruno said in a follow-up tweet. "Transforming the rocket in steps."
With a new infographic, Bruno showed how Vulcan's heritage dates back to 1990 and draws from Lockheed Martin's Atlas 1, 2 and 2A. The chart also depicts how ULA envisions Vulcan evolving through 2024, when it will take advantage of reusable rocket engines.
This evolution includes the addition of ACES, a new upper stage known as the Advanced Cryogenic Evolved Stage, as well as a new first stage featuring the methane-fueled BE-4 engine, which is being developed by Blue Origin of Kent, Washington. ULA is also working with Aerojet Rocketdyne on the AR-1 engine, in case the Blue Origin-funded BE-4 runs into developmental issues.
Bruno unveiled the first details about Vulcan in a series of interviews earlier this year and then announced additional details during a grand unveiling in April at the Space Symposium in Colorado Springs, Colorado. Vulcan is expected to pick up much of ULA's medium-class launch market beginning around 2021, but the move means the end of ULA's current workhorse rocket, the Atlas 5.

Boeing said Wednesday it has turned down an offer from Aerojet Rocketdyne to buy United Launch Alliance, a Boeing-Lockheed Martin joint venture that operates the Atlas and Delta rocket fleets.
The decision keeps ULA's plan to sel ect a new engine for the company's next-generation Vulcan rocket some time next year. Aerojet Rocketdyne and Blue Origin are in the running to be the engine supplier.
The unsolicited offer, reportedly worth $2 billion, was made by the company that builds rocket engines for ULA's Delta 4 launcher and Atlas 5 upper stage.
"With regard to reports of an unsolicited proposal for ULA, it is not something we seriously entertained for a number of reasons," said Todd Blecher, a spokesperson for Boeing's defense and space division, in an email to Spaceflight Now. "Boeing is committed to ULA and its business, and to continued leadership in all aspects of space, as evidenced by the agreement announcement last week with Blue Origin."
ULA says it prefers an engine made by Blue Origin, a company founded by Amazon.com chief Jeff Bezos, to power the company's next-generation Vulcan rocket. Aerojet Rocketdyne is working on its own engine called the AR1, but ULA officials say its development is two years behind Blue Origin's.
Officials announced an agreement Sept. 10 to expand Blue Origin's engine production capability to ramp up for the Vulcan program.
"Under the agreement, Blue Origin will expand its existing BE-4 production capability already established at its Kent, Washington, development facility to accommodate the initial production rate needed for the Vulcan launch vehicle," said Jessica Rye, a ULA spokesperson.
The BE-4 engine in development by Blue Origin is nearing its critical design review, a milestone in which the powerplant's design will be frozen and managers will deem it ready for hardware production.
The AR-1 engine by Aerojet Rocketdyne is closing in on its preliminary design review, Bruno wrote in a post to his Twitter account.
Both use staged-combustion designs, a more efficient class of rocket engines not currently manufactured in the United States.
United Launch Alliance's corporate parents are approving quarterly tranches of funding for the Vulcan rocket, eyeing concerns about the future supply of Russian-made RD-180 engines for the Atlas 5 rocket's first stage booster.
Under pressure from newcomer SpaceX, ULA is aiming for launch costs of less than $100 million per Vulcan flight, and the company plans to roll out a scheme in the 2020s to capture booster engines after launch for refurbishment and reuse. An upgraded upper stage to replace the Centaur rocket is also in ULA's long-term plans.
First will come a basic Vulcan configuration relying on the same Centaur stage, and similar solid rocket boosters and payload shrouds from the Atlas 5. The new item will be a redesigned first stage core with an American-made engine.
ULA's designers are working on two versions of the company's Atlas 5 replacement rocket: One with at least a 5.1-meter (16.7-foot) diameter core stage with two BE-4 main engines, and another with a slimmer 3.8-meter (12.5-foot) wide first stage with a pair of AR1 powerplants.

The wider stage, based on tanks flown on ULA's Delta 4 rocket, is needed to accommodate methane fuel for the BE-4 engines, which each generate about 550,000 pounds of thrust at full throttle. The AR1 burns rocket-grade kerosene fuel, with higher density than methane, and can be flown with a booster stage the same diameter as the Atlas 5, Bruno said.
But the version with AR1 engines would feature a lengthened core stage from the tanks flying on the Atlas 5, and a feed line for liquid oxygen coursing down the center of the rocket. The Atlas 5's liquid oxygen fuel plumbing runs outside the first stage to reach the rocket's RD-180 engine.
ULA has only released artists concepts and promotional materials for the Vulcan configuration with BE-4 engines.
Blue Origin founder Bezos told reporters this week his company's engineers have worked on the BE-4 engine for more than three years. It is an evolution of Blue Origin's BE-3 engine, which powers the company's suborbital New Shepard launcher designed for space tourism.
"The BE-4 engine has a lot of unique characteristics, technically, but I think the most unique feature of the BE-4 engine is that it's fully funded," Bezos said. "It's not something you see with rocket engine programs very often."
With a net worth of nearly $50 billion, according to Forbes, Bezos established Blue Origin in 2000 and has personally funded the bulk of the company's development projects.
"Our approach on this is very simple, which is we stay heads down focused on the technology," Bezos said Tuesday. "We're going to build the best 21st century engine that we can for ULA. Ultimately, they'll make the decision about what they want to do, but we're going to work our butts off to give them a great engine."
Blue Origin President Rob Meyerson said in April the BE-4 engine's development will finish in 2017 after full-scale testing in late 2016 at the company's West Texas test facility. That schedule is in line with ULA's plans to conduct the first test launch of the Vulcan rocket in 2019.
Tests of the engine's powerpack and propellant injectors are ongoing, Meyerson said.
More than 60 staged-combustion tests of the BE-4 engine are already in the books, Bezos said in a statement in the Sept. 10 announcement on BE-4 engine production in Washington.
Bezos visited Cape Canaveral on Tuesday to announce plans to set up a commercial rocket factory and launch pad for Blue Origin's own orbital launch vehicle, which will fly with BE-4 engines and could eventually be a competitor for ULA's Vulcan.
He did not disclose details on Blue Origin's launcher.
"If you look at the reliability track record that (ULA) has had, it's truly extraordinary, and when you look at some of the national security payloads, that is the No. 1 factor," Bezos said. "Space is pretty big. There are a lot of opportunities, and there's room for multiple winners. We're going to work our butts off to make sure that the BE-4 engine is the best possible engine for United Launch Alliance."

Aerojet Rocketdyne's AR1 engine is two years behind Blue Origin's current schedule.
Julie Van Kleeck, the company's vice president of space programs, told Spaceflight Now in an interview that ULA and Aerojet Rocketdyne submitted a joint proposal to the U.S. Air Force, which plans to dole out a combined $160 million to multiple contractor teams to advance work on new U.S. rocket engines.
The Air Force is expected in the coming weeks to sel ect up to four winners fr om the companies that submitted bids, a list industry officials expect to include Blue Origin, Orbital ATK, and perhaps SpaceX, which is working on its own methane-fed Raptor rocket engine for a new series of rockets bigger than the existing Falcon family.
Congress wants the Air Force to cease use of the RD-180 engine by 2019, but military leaders say that schedule is tight. There is disagreement between the House and the Senate on how many RD-180 engines can be used for future military launches, with the Senate holding to a lower number.
The disparity has raised complaints fr om the Air Force and ULA that limiting RD-180 engine use would give SpaceX control of the military launch market, which has been dominated by ULA since the merger of the Atlas and Delta rocket programs in 2006. The Air Force policy's is to have two independent rockets to loft the military's most critical satellite payloads, and ULA has announced it plans to retire the single core "medium" version of its Delta 4 launcher -- which has all U.S. propulsion -- in 2018 or 2019 because it is not cost-competitive with the Falcon 9 or Atlas 5.
"We'll be providing an offering in conjunction with ULA," Van Kleeck said in August. "We're on schedule. We're investing pretty heavily in the engine right now, and we're on schedule to get to a preliminary design review."
Van Kleeck said testing of sub-scale engine hardware is going well, with some components set to undergo a full mission duty cycle test this winter. Aerojet Rocketdyne is working on the AR1 engine with internal company funds, but the engine's planned readiness date in 2019 hinges on outside support.
"We're still looking to qualify the engine and certify it in 2019," she said.

United Launch Alliance Selects Orbital ATK to Provide Solid Boosters for Atlas V and Vulcan Launch Vehicles
http://www.orbitalatk.com/news-room/release.asp?prid=74

ЦитатаCentennial, Colorado and Dulles, Virginia 22 September 2015 - Today United Launch Alliance (ULA) and Orbital ATK, Inc. (NYSE: OA) announced a long-term strategic partnership in which Orbital ATK will become the sole provider of solid rocket boosters for ULA's Atlas V and Vulcan launch vehicles, effective in 2019 when the new motors are ready for launch.

"As ULA transforms the space lift industry, strong partners such as Orbital ATK are critical to reducing cost, introducing cutting-edge innovation and continuing our focus on mission success," said Tory Bruno, ULA's president and CEO. "We have relied for decades on Orbital ATK's industry leading rocket motor technology, which is ideally suited to support our future rocket launch plans."

Under this partnership, Orbital ATK is investing in the design, development and qualification of two new rocket motors with design similarities to each other that leverage the company's proven solid motor technology. These motors will significantly lower the price to ULA and to the U.S. government. They will be used to support launches of ULA's Atlas V and Vulcan vehicles and will also be commercially available to support other customers.

"With this strategic partnership, ULA and Orbital ATK will offer customers better value and reliable access to space," said David W. Thompson, president and CEO of Orbital ATK. "The capabilities and technology of the newly-merged Orbital ATK enabled us to expand the partnership with ULA to help lower costs and maintain the highest standards of mission assurance."

Development of the new solid rocket boosters will commence immediately to support their introduction on ULA's Atlas V vehicle in late 2018 and on ULA's Vulcan vehicle in mid-2019. Vulcan, ULA's next generation launch vehicle, is anticipated to transform the future of space launch for the government and commercial market, making it more affordable, accessible and commercially available.

"Our ability to deliver critical national security, scientific and commercial satellites into the correct orbit for each mission is filled with risks and challenges, and ULA has delivered every time," said Bruno. "This reliability will continue as we develop the right vehicle with the right team."

The new solid motor booster agreement expands the long-term relationship between ULA and Orbital ATK that already includes the supply of composite structures, nozzles, propellant tanks and booster separation motors for the current versions of Delta IV and Atlas V rockets. In addition, ULA will supply two Atlas rockets to provide launch services for Orbital ATK's Cygnus spacecraft on cargo delivery missions to the International Space Station for NASA in late 2015 and early 2016. Orbital ATK is also developing a fully integrated third stage to launch NASA's Solar Probe Plus mission on ULA's Delta IV Heavy rocket in 2018.

ULA has a strong heritage in providing reliable space access for government and commercial entitles under the Evolved Expendable Launch Vehicle (EELV) program. The EELV program was established by the United States Air Force to provide assured access to space for Department of Defense and other government payloads. The company recently marked the 99th successful one-at-a-time launch since the company was formed in December 2006.

ЦитатаULA selects launch pads for new Vulcan rocket

United Launch Alliance's next-generation Vulcan rocket will lift off from the company's existing Atlas 5 launch facilities in Florida and California, according to the company's Vulcan program manager.
The launch pads at Cape Canaveral and Vandenberg Air Force Base will require modifications to accommodate the Vulcan booster, which is wider than the Atlas 5 rocket's existing first stage, said Mark Peller, ULA's Vulcan program manager, at the International Symposium for Personal and Commercial Spaceflight in Las Cruces, New Mexico.
Peller confirmed Thursday widely-held suspicions that the Vulcan will be based at the Atlas 5's launch pads. ULA chief executive Tory Bruno declined to identify the Vulcan's launch pads in an Oct. 2 meeting with reporters.
"Vulcan will fly out of our heritage Atlas launch pads, so SLC-41 on the East Coast and SLC-3E on the West Coast," Peller said. "They do require a moderate amount of modification to accommodate both the larger Vulcan vehicle and the addition of liquified natural gas propellant distribution capability."
The BE-4 engines tagged to power the Vulcan first stage burn liquified natural gas, similar to methane.
ULA officials say they plan for the Atlas 5 and Vulcan launchers to fly concurrently for several years, with the maiden Vulcan launch expected in 2019 and retirement of the Atlas 5 in the early 2020s.
Launch pads in Florida and California designed for the Delta 4 rocket will remain operational until an upgraded upper stage is ready to fly around 2023, Peller said, allowing ULA to retire the triple-core Delta 4-Heavy rocket. The Delta 4's single-core medium-lift variant will make its final flight around 2019, ULA officials said.
With the final launch of the Delta 2 rocket expected in late 2017 or early 2018, and the phase-out of the Delta 4 family in the early 2020s, ULA will downsize from five active launch pads to two, keeping one facility on each coast for equatorial and polar orbit missions.
Construction crews are building a crew access tower at the Atlas 5's East Coast pad at pad 41, allowing astronauts to board Boeing's commercial CST-100 Starliner spaceship for flights to the International Space Station. Boeing has picked the Atlas 5 as the crew capsule's launcher.

At Vandenberg on California's Central Coast, Space Launch Complex 3-East is set up for on-site assembly of the Atlas 5 inside a moveable service gantry. Atlas 5s at Cape Canaveral are stacked inside a nearby fixed vertical hangar, then rolled to the launch pad before liftoff.
ULA executives have stressed the importance of reducing ULA's footprint. Bruno said launch pads are the single biggest element of the company's fixed costs and facility costs.
The Vulcan rocket is ULA's answer to market forces brought on by newcomer SpaceX, which sells Falcon rockets at a lower price than Atlas and Delta launchers, and political pressure to end reliance on the Atlas 5's Russian-built RD-180 engines for U.S. national security missions.
The Boeing-Lockheed Martin joint venture is working on two designs for the next-generation booster: One with at least a 5.1-meter (16.7-foot) diameter core stage with two BE-4 main engines, and another with a slimmer 3.8-meter (12.5-foot) wide first stage with a pair of AR1 powerplants.
The BE-4 engine being developed by Blue Origin, a space established by Amazon.com founder Jeff Bezos, is the "primary option" for the Vulcan's main propulsion system, Peller said.
But the company is funding work on Aerojet Rocketdyne's AR1 engine as a backup option.
Both engines use oxygen-rich staged combustion technology, a technique that minimizes propellant waste during launch. The BE-4 will burn a combination of super-cold liquified natural gas and liquid oxygen, while the AR1 consumes kerosene fuel at room temperature.

Either way, the new rocket would use two engines to provide more than a million pounds of total thrust. Ground crews could add up to six strap-on solid rocket boosters from Orbital ATK to lift heavier payloads into space.
"The BE-4 from Blue Origin is our primary option," Peller said. "That's wh ere the majority of our focus is right now going forward. We realize that engine development is very difficult and fraught with risk. We are a very important provider of launch services to our country, and we want to make sure that we continue to provide assured access to our government customers, so we felt it's a prudent step to take to maintain a backup option, and that is the AR1."
ULA officials have said the AR1 engine, which generates 500,000 pounds of thrust at sea level, could be incorporated into a new booster stage based on the Atlas 5 design. The AR1 consumes the same propellant mix -- liquid oxygen and refined rocket-grade kerosene -- as the RD-180 engine currently affixed to the bottom of Atlas 5s.
"It is not a drop-in replacement but could be accommodated into an AR1 variant of the Vulcan vehicle on the drawing board as well -- a little more similar to Atlas than what were doing with the BE-4 Vulcan vehicle," Peller said. "The AR1 engine is going through development, and that team is on track to have their preliminary design review for that engine later this year."
Aerojet Rocketdyne, ULA's current primary engine provider, attempted a $2 billion takeover of ULA in September. Weeks later, ULA sel ected Orbital ATK over Aerojet Rocketdyne as the company's sole supplier of solid rocket boosters.
Once the all-American booster engine is introduced on Vulcan, ULA eyes an upgraded Advanced Common Evolved Stage, or ACES, to replace the Centaur upper stage that has been flying since the 1960s. Engineers plan to begin recovering engine pods fr om the Vulcan rocket for refurbishment and reuse in the 2020s.
Rob Meyerson, president of Blue Origin, said the BE-4 engine is approaching its critical design review, a key development milestone that is often a gate to begin production. Officials have said the BE-4, which Blue Origin started working on in 2011, is on track to be certified for flight by 2017.
Blue Origin announced Sept. 30 the completion of more than 100 staged combustion tests of the BE-4 engine. The firings at Blue Origin's West Texas test site included a representative BE-4 preburner and a regeneratively-cooled thrust chamber using multiple full-scale injector elements, the company said in a statement.
The engine on the test stand us a sub-scale BE-4 generating about 20,000 pounds of thrust, Meyerson said.
"It demonstrates all of the injector elements," he said. "We're demonstrating performance, we're demonstrating combustion stability, we're demonstrating the manufacturing techniques we need to build those injectors and those chambers.
"The powerpack itself is the other part of the testing," Meyerson said. "The powerpack includes the main pump, the boost pump, the preburner, and all the main valves on the engine, and we've been testing that extensively as well."
Meyerson said the BE-4 engine is also intended to power Blue Origin's own unnamed orbital launch vehicle scheduled to fly by the end of the decade. Blue Origin's suborbital New Shepard booster, designed for space tourist and research flights, uses a smaller hydrogen-fueled BE-3 engine.
"We didn't go into this 10 years ago with the idea that we want to build engines for the community," Meyerson said. "We went into this going to build technologies to support New Shepard, and those engines happen to be very unique in the industry, and one-of-a-kind capabilities that can support multuple launch companies."
The most unique trait of the BE-4 engine is its funding pipeline, according to Meyerson.
"I emphasize that the BE-4 is fully funded because a rocket engine that's available for others to buy, that's a new trajectory," Meyerson said. "Jeff Bezos has stepped in and invested in the BE-4. ULA has come in and made an investment as well for application on the Vulcan, and I think that's unprecedented."
ULA chief executive Tory Bruno said the AR1 engine is about two years behind the BE-4, and managers will decide on an engine by the end of 2016.
"We see that (decision) as some time next year, probably late next year," Peller said. "We're monitoring the risk burn down with our primary option, and with more progress both on our side with the booster and with Blue Origin, we'll make that decision."

ЦитатаBlue Origin vs. SpaceX engines

Blue Origin has not yet flown its BE-4 engines (shown below). However, it recently completed its 100th ground test, calling the test series "a key milestone (https://www.blueorigin.com/news/news/blue-origin-completes-more-than-100-staged-combustion-tests-in-development)" in the engine's development. And it plans to have the engine ready for flight by 2017. 
Blue Origin (https://www.blueorigin.com/technology)
While the BE-4 engine is of a different design than the less powerful BE-3 engine that flew on Nov. 24, the flight's success is a testament to Blue Origin's spaceflight abilities.
In addition, the BE-4 engines will each generate 550,000 pounds of thrust (https://www.blueorigin.com/technology) -- the propulsive force a rocket uses to get to space. In comparison, each of SpaceX's latest, upgraded Merlin engines, which power the Falcon 9 rocket (and are shown below) generate 170,000 pounds of thrust (http://spaceflightnow.com/2015/09/25/first-static-fire-completed-on-upgraded-falcon-9/).
Uploaded by Craigboy on Wikipedia (https://en.wikipedia.org/wiki/Merlin_%28rocket_engine_family%29#/media/File:Merlin_1D_engines_and_octaweb_harness.jpg)
The ULA Vulcan rocket will be what is called a heavy-launch vehicle, capable of ferrying extremely heavy loads into space -- a task that requires an enormous amount of rocket engine power.
Strapped with two BE-4 engines, it will launch with 1.1 million pounds of thrust and carry payloads of up to 17.3 metric tons (http://www.spacelaunchreport.com/vulcan.html) (38,000 pounds) to low-earth orbit -- where rockets go to transport payloads to the International Space Station.
By comparison, SpaceX's next-generation heavy-launch vehicle, the Falcon Heavy, will use essentially three Falcon 9 rockets strapped together. Each Falcon 9 contains 9 Merlin engines.
The Falcon Heavy is currently under construction at SpaceX and will generate 3.96 million pounds of thrust and lift up to 117,000 pounds into low-earth orbit. Its first demo flight, which was supposed to take place this year, was re-scheduled for spring 2016 (http://spacenews.com/first-falcon-heavy-launch-scheduled-for-spring/).

"Blue Origin is a super-rich girl, and then there is this poor girl over here, Aerojet Rocketdyne. But we have to continue to go to planned rehearsal dinners, buy cakes and all the rest with both."
 
ULA is now working with Kent, Washington-based Blue Origin, owned by Amazon founder Jeff Bezos; and Aerojet Rocketdyne of Rancho Cordova, California, on RD-180 replacements.
Aerojet Rocketdyne's AR1 engine uses liquid oxygen and kerosene. Blue Origin's BE-4 uses liquid oxygen and methane.
Tobey said Bezos has invested $500 million of his own money in Blue Origin and, as demonstrated during the explosion of a Blue Origin engine on a test stand, is willing to "open his checkbook" to pursue what for Bezos is more a passion than a quest for business profit.
Compared to Bezos, Aerojet Rocketdyne's AR1 is working off a relatively small government budget, Tobey said. He did not reference a recent U.S. Defense Department announcement that substantially more funds would be arriving to develop the AR1.
Comparing the two engine developments - Aerojet Rocketdyne pursuing the classic government funding route, while Blue Origin has a billionaire owner who can act lightning-fast - the two companies' situations do not favor Aerojet Rocketdyne.
"Compare it to having two fiancées, two possible brides," Tobey said of ULA's approach to the two. "Blue Origin is a super-rich girl, and then there is this poor girl over here, Aerojet Rocketdyne. But we have to continue to go to planned rehearsal dinners, buy cakes and all the rest with both.
"We're doing all the work on both, and the chance of Aerojet Rocketdyne beating the billionaire is pretty low. Basically we're putting a whole lot more energy into BE-4 for Blue Origin."
Using methane would be new for the U.S. space sector, imposing risks, but Tobey said the BE-4 engine is only 60 percent of the cost of the AR1, a clear advantage in today's cost-driven market.
Of both engines, he said: "They are never going to outperform the RD-180."

United Launch Alliance Completes Preliminary Design Review for Next-Generation Vulcan Centaur Rocket (http://www.ulalaunch.com/ula-completes-Vulcan-Centaur-PDR.aspx)

ЦитатаCentennial, Colo., (March 24, 2016) - United Launch Alliance (ULA) successfully completed the Preliminary Design Review (PDR) for the Vulcan Centaur launch vehicle with dual Blue Origin BE-4 engines. The PDR, a major milestone in development of the Vulcan launch vehicle, confirms that the design meets the requirements for the diverse set of missions it will support. The ULA team will build upon this milestone to refine and test key elements of the design while executing a busy manifest of 14 launches in 2016.  

"The completion of the Vulcan Centaur rocket's PDR is the first of several major and very exciting milestones in the launch vehicle's development," said Tory Bruno, ULA president and chief executive officer. "We have a strong path to get to a 2019 flight test of this new, highly-capable American launch vehicle."

The Vulcan Centaur rocket design leverages the proven success of the Delta IV and Atlas V launch vehicles while introducing new technologies and innovative features which will ensure a reliable and affordable space launch service along with engines developed and manufactured in the United States. The Vulcan Centaur provides a path to replacement of the current fleet of Delta IV and Atlas V vehicles and will service a diverse range of markets including commercial, civil and national security space customers.

"Vulcan Centaur will revolutionize spaceflight and provide affordable, reliable access to space with an American main engine," said Mark Peller, ULA's program manager for major development.

In addition to the Blue Origin BE-4 engine, Aerojet Rocketdyne is developing the AR1 engine which could power the Vulcan Centaur. Such strategic partnerships for American main engines, Orbital ATK for the solid rocket boosters and RUAG Space for domestically-produced composite structures enable collaborative development of Vulcan maximizing the value of this new launch capability.

With more than a century of combined heritage, United Launch Alliance is the nation's most experienced and reliable launch service provider. ULA has successfully delivered more than 100 satellites to orbit that provide critical capabilities for troops in the field, aid meteorologists in tracking severe weather, enable personal device-based GPS navigation and unlock the mysteries of our solar system.

ЦитатаULA and SpaceX on different paths toward rocket reuse
13 April, 2016[/li][li]BY: James Drew
Washington DC
 
When it comes to dramatically lowering the cost of access to space, industry titans agree that reusability is key. But that's where the unity ends, as industry upstart SpaceX and long-time launch provider //United Launch Alliance (ULA) take two very different approaches to reusability.
Speaking at the 32nd Space Symposium in //Colorado Springs, Colorado this week, ULA president and chief executive Tory Bruno said it would take a series of 10 launches just to recoup the manufacturing and logistical costs associated with building and recovering a returned booster.
SpaceX's successful Falcon 9 vertical landing on an ocean landing pad last week was undoubtedly a historic accomplishment, but ULA maintains that its engine recovery concept makes more sense from a business perspective.
Last month, the company completed a preliminary design review of its Vulcan Centaur next-generation launch vehicle, powered by dual Blue Origin BE-4 liquefied natural gas/liquid oxygen engines. It's also considering the //Aerojet Rocketdyne AR-1 oxygen-rich staged combustion kerosene engine.
Eventually, the Vulcan design will be updated to jettison those engines. The engine module will be protected on its high-speed fall back to Earth by a hypercone heatshield before deploying a parachute and being caught mid-air by an awaiting helicopter.
Bruno says reusable rockets might someday be economically viable, but it's a difficult place to start and the costs quickly snowball.
"If you could reuse your first-stage booster and it didn't cost you anything to do that, you might be able to knock 25-30% off the price of going to space," he said. "That's worth doing; those are real dollars. Unfortunately, it's not free.
"When we looked at that math, we figure you've got to do about 10 reuses to break even, which is pointless because you're doing this to save money, so you've got to do this about 15 times."
Bruno contends that the rocket engines are the most complex and expensive part of the rocket, whereas most of the weight is in the less expensive fuel tanks.
A typical Atlas V mission costs upwards of $160 million, whereas the Vulcan's target is around $100 million per launch. Vulcan won't be introduced with the reusable engine stage, but that capability will come later as the third step in ULA's step transition to a next-generation space launch system, which starts between the Vulcan first flight in 2019 and introduces a reusable thrust stage around 2024. ULA nearer-term priority is transitioning from the Centaur upper stage to a new Advanced Cryogenic Evolved Stage (ACES).
"Rocket engines are complicated and arguably more complicated than the whole rest of the rocket that you put together," Bruno says. "But all the weight is in the fuel tanks - two-thirds of the weight, the cheapest thing on the rocket. What if you just bring the engines back? You don't have all these extra systems; you can do it every time.
"The economic hurdle to break even is only two reuses and it's five times easier. Our approach is to start there."

ЦитатаDecision on Vulcan engine could slip to 2017
by Jeff Foust (http://spacenews.com/author/jeff-foust/) -- September 12, 2016
ULA CEO Tory Bruno said the company will wait until the BE-4 perform a full-scale static-fire test before making a decision on using that engine in its Vulcan rocket. Credit: ULA  
 
KENNEDY SPACE CENTER, Fla. -- A decision on what engine will power United Launch Alliance's next-generation Vulcan rocket could be pushed back until next spring depending on the timing of a key engine test, ULA's chief executive said Sept. 8.
In an interview here shortly before the successful Atlas 5 launch of NASA's OSIRIS-REx asteroid sample return mission, Tory Bruno said a decision on whether to use the BE-4 engine under development by Blue Origin was pending a full-scale engine test that had been expected by late this year.
"It's really tied not so much to the calendar but to a technical event," Bruno said of the schedule for an engine decision. "We want to have a full-scale static firing of the BE-4, so that we understand that it's going to hit its performance and it's going to be stable."
"That may occur by the end of the year, but I could see it moving into the spring a little bit, to make sure we have enough test data and we feel confident about where we're at," he added.
He emphasized that the BE-4 remained the "primary path" to be used on the first stage of the Vulcan, ahead of the AR1 engine under development by Aerojet Rocketdyne. "They're out in front," Bruno said of the BE-4.
Bruno also confirmed that development of Vulcan is still being approved on a quarterly basis by ULA's board of directors, comprised of executives from its corporate parents, Boeing and Lockheed Martin. Those regular reviews, he said, have not posed a problem for work on Vulcan.
"They've been very supportive, they've been terrific," he said of ULA's board. "It helps that we're performing well."
Key to Vulcan's development is ULA's ability to continue to win contracts for its existing Atlas and Delta vehicles. ULA did win in August two sole-source awards for Delta 4 Heavy launches for the National Reconnaissance Office in 2020 and 2023, a deal with an estimated value of $700 million. However, Bruno said that upcoming head-to-head competitions with SpaceX were also critical to ULA.
"They're important to the business because the investment dollars for Vulcan come from ongoing operations," he said. "Our investment comes from the money we make by continuing to sell space launch services, so we have to keep maintaining a viable business on those launches in order to generate those funds."
ULA declined last year to bid on the first EELV competition, for a GPS 3 satellite. Bruno said that two of the issues that kept ULA from bidding, a lack of available RD-180 engines and what he called "very strange" accounting requirements, have both been resolved.
A third obstacle to bidding, and one that remains today, is the use of selection criteria based only on price. "I don't personally have any experience with that applying to space or space launch, which is a complex, high-risk kind of endeavor. The events of last week, I think, highlight that," he said, a reference to the destruction of a SpaceX Falcon 9 on the pad Sept. 1 prior to a static-fire test.
That emphasis on price, he argued, ignores the other attributes of the Atlas 5 that he believes offers a greater value, including its reliability and performance. "When all of that is considered, Atlas is absolutely very competitive and, in my view, more often than not, hands-down the best value," he said. "On a pure price competition, none of that plays, and we are less competitive because it takes all of our strengths off the table."
That emphasis on price remains in the request for proposals issued by the Air Force in August for a second GPS 3 satellite launch, but Bruno suggested ULA will still submit a bid by the Sept. 19 deadline. "It's my strong desire to participate in every competition that I can and I'm qualified for," he said, declining to go into more details because of the ongoing competition.
Bruno also said he is working to make more inroads into the commercial launch market with the Atlas 5, particularly since the recent Falcon 9 failure and delays in the Proton launch vehicle caused by a June launch anomaly have constricted the supply of launch vehicles available for commercial missions. Two commercial Atlas 5 missions are scheduled through the end of the year, including the Sept. 16 launch of DigitalGlobe's WorldView-4 satellite and an EchoStar satellite planned for launch in December.
Bruno said there is room for more commercial launches in the near future. "I think there was a perception in the commercial marketplace that ULA was really focused on NASA and the Air Force and there was not availability in our manifest," he said. "I have slots reserved and available for people next year and the year after."

Как-то СТ-100 надо же пускать. Или Боинг что-то не договаривает или в Боинге сидят дураки. Либо Атласы будут продолжать летать либо переход на пилотируемый Вулкан. Одно из 4-х.

ЦитатаSMC, ULA Enter into CRADA to Certify Vulcan Launch Vehicle
 Press Release From: Los Angeles Air Force Base (http://www.losangeles.af.mil)
 Posted: Tuesday, September 27, 2016
 
The Space and Missile Systems Center signed a Cooperative Research and Development Agreement (CRADA) with United Launch Alliance (ULA) as part of the company's effort to certify its new Vulcan launch vehicle for National Security Space (NSS) missions. This cooperative, jointly-written agreement facilitates data exchanges and protects proprietary and export-controlled data. The CRADA will be in effect until all non-recurring design validation activities for Vulcan are complete.
 
This CRADA enables the Air Force to evaluate the Vulcan launch system according to the Air Force's New Entrant Certification Guide (NECG), and contains a detailed Certification Plan that specifies all of the non-recurring activities. As part of the evaluation, SMC and ULA will look at flight history, vehicle design, reliability, process maturity, safety systems, manufacturing and operations, systems engineering, risk management and launch facilities. SMC will monitor at least two certification flights to meet the flight history requirements outlined in the NECG. ULA will give the US Government specific levels of insight into the design and testing of the vehicle during its development; the breadth and depth of this insight allows for the number of certification flights to be two. Once portions of the non-recurring validation are complete, the SMC commander may make a determination to grant certification. This approach is consistent with other CRADAs.
 
"The certification process provides a path for launch-service providers to demonstrate the capability to design, produce, qualify, and deliver a new launch system and provide the mission assurance support required to deliver NSS satellites to orbit," said Lt. Gen. Samuel Greaves, Air Force program executive officer for Space and Space and Missile Systems Center commander. "This process ensures that we continue to have assured access to space."
 
While certification does not guarantee a contract award, it does enable a company to be awarded competitive launch services contracts.
 
In addition to the Vulcan CRADA, SMC anticipates entering into additional CRADAs with SpaceX for their Falcon Heavy rocket and with Orbital-ATK for their Next Generation Launcher.
 
Currently, ULA's Delta IV and Atlas V, and SpaceX's Falcon 9 Upgrade are the only certified launch vehicles for sending NSS payloads into orbit. Having multiple certified launch vehicle providers and multiple families of launch systems bolsters U.S. assured access to space.
 
The Space and Missile Systems Center, located at Los Angeles Air Force Base, Calif., is the U.S. Air Force's center for acquiring and developing military space systems. Its portfolio includes the Global Positioning System, military satellite communications, defense meteorological satellites, space launch and range systems, satellite control networks, space based infrared systems and space situational awareness capabilities.

@torybruno Ah. since AR-1 produces significantly less thrust than RD-180 would a solution be dual engine or more SRBs?
Both Vulcan/BE4 and Vulcan/AR1 configurations call for 2 engines, which is about 30% more thrust than AtlasV. Removes at least one SRB

ЦитатаBruno: Vulcan engine downselect is Blue's to lose
by Jeff Foust (http://spacenews.com/author/jeff-foust/) -- April 5, 2017

Blue Origin founder Jeff Bezos speaks in front of his company's New Shepard suborbital vehicle on display at the 33rd Space Symposium in Colorado Springs April 5. Bezos said the company still plans to start flying people on suborbital space tourism flights by the end of 2018, although the company has yet to start selling tickets or even setting a ticket price. Development of New Shepard, he said, is informing the company's plans for an orbital launch vehicle, New Glenn, that will use the same BE-4 engines that United Launch Alliance is considering for its Vulcan rocket.

COLORADO SPRINGS -- United Launch Alliance is prepared to sel ect Blue Origin's BE-4 engine for its Vulcan launch vehicle this year if the engine passes an upcoming series of tests, the company's chief executive said April 5.

In an interview during the 33rd Space Symposium here, Tory Bruno said that tests of the BE-4 engine, scheduled to begin "very soon" at Blue Origin's test site in West Texas, are the last major hurdle the engine must clear before ULA decides to use it on Vulcan.

"The economic factors are largely in place now and the thing that is outstanding is the technical risk," Bruno said. "That's why we keep talking about the engine firing."
A major aspect of the engine tests, he said, is to determine the degree of combustion instability the BE-4 has when the engine starts. "Any time when you are developing a new rocket engine, any time you change the scale or the fuel, you are at risk of this phenomenon," he said. The BE-4 engine is the largest engine developed to date that uses methane as fuel, rather than more common alternatives like kerosene or liquid hydrogen.

"We look first to the combustion instability as the chief technical risk that must be retired before we'd be able to pick an engine," Bruno said. He anticipated a series of tests, lasting for several weeks, where the engine's thrust is gradually increased to measure its performance and determine if it suffers from combustion instability.

Bruno said he was encouraged by tests of some key engine components, including the preburner, a smaller version of the main engine that powers the engine's turbomachinery. "The good news is the preburner is running like a top," he said. "We're starting to get more and more confidence that we're going to have a good experience when we run a full-scale engine."

If the tests all go as planned, Bruno said ULA could be ready to formally sel ect the BE-4 in as soon as 60 to 90 days. "But it could take longer," he added. "It's not on the calendar."

Rob Meyerson, president of Blue Origin, confirmed in an April 5 interview that test of the BE-4 will start in the next several weeks. One engine is already at the company's test site, with two more shipping there soon.

"We wanted to go into the test program hardware-rich," he said. With those engines and other equipment at the test site, "we can move through the test program quite rapidly." He said that testing would continue after ULA made its decision, with final certification of the BE-4 planned for late 2018 or early 2019.

While Bruno will make the decision about the engine, he will get plenty of advice. He said he recently established an independent non-advocate review (INR) team of outside experts to review the overall engine evaluation process. That team includes former Secretary of the Air Force Sheila Widnall; retired Air Force Maj. Gen. Susan Mashiko, former deputy director of the National Reconnaissance Office; and Ray Johnson, former vice president for space launch operations at the Aerospace Corp.

Bruno said Congress also established a separate INR team, comprised of engineers fr om NASA's Marshall Space Flight Center, to review the engine selection process. "I was actually happy to hear that they did that," Bruno said, adding that this team had access to the same data as ULA's own review team.

Bruno added that he expected the Air Force would also seek access to the test data and provide ULA with its own opinion about the engine. "I will hear all of those opinions and it will be super easy if everybody says the same thing," he said. "If they do not, then we will resolve that. And then we will make a choice."

Aerojet Rocketdyne's AR1 engine remains the alternative for Vulcan should the BE-4 run into technical problems. Development of the AR1 is 18 to 24 months behind the BE-1, he said, because it started later. "I have confidence they can get their engine to work" because of its use of a more conventional fuel, kerosene.

Blue Origin, though, has the financial edge. Bruno said ULA already haa a firm fixed-price deal with Blue Origin for "a large enough quantity" of engines that covers initial Vulcan missions. Those engines will be produced initially at Blue Origin's factory in Kent, Washington.

"Their production capability actually looks quite good," Bruno said of those initial BE-4 engine plans. "My INR heads came back to me and said they are very comfortable with that production capability already."

Later engines will be built at a separate facility Blue Origin plans to develop in the next few years that will be designed to produce dozens of engines a year. "We're in the process of site selection for a full production site," Meyerson said. He declined to identify the locations being considered, but said a decision should be made in the next six months.

Bruno said that he expected to decide on the Vulcan engine this year, but wouldn't be rushed into one. "I get to make this decision, like, once. This is a big decision and if you don't get it right, it's very hard to come back fr om that," he said. "So I'm going to take my time and listen to all these experts and stakeholders and then do it."

A full-scale BE-4 engine developed by Blue Origin, the space company founded by Amazon.com's Jeff Bezos, is installed on a test stand in West Texas for a series of hotfire tests that United Launch Alliance will closely examine before settling on the reusable methane-fueled engine for its new-generation Vulcan rocket.

If the engine firings are successful, ULA will likely sel ect the BE-4 engine for the first stage of the Vulcan booster set to begin launching by the end of 2019, according to Tory Bruno, ULA's president and chief executive.

ULA will decide between Blue Origin's BE-4 engine and the kerosene-fueled AR1 powerplant fr om Aerojet Rocketdyne, a more traditional aerospace supplier.

But the BE-4 is ahead of the AR1 in development, and Bruno said ULA will go with the Blue Origin-built engine as soon as the first series of test-firings are successfully accomplished.

"When that engine begins its testing and we collect enough data, we'll be able to decide if the engine is going to work and meet the performance requirements," Bruno said April 4 at the 33rd Space Symposium in Colorado Springs. "When that data is in hand, then we'll make the down-selection. I expect that to be this year."
Blue Origin kicked off development of the BE-4 engine for its own launcher several years before ULA approached Bezos's company. Bruno and Bezos announced the engine partnership in September 2015, a few months before ULA unveiled the name and basic design of the Vulcan launch vehicle.

At the time, full-scale testing of the BE-4 engine was expected to begin before the end of 2016. A timetable for the first full-scale BE-4 hotfire test has not been released, but officials fr om ULA and Blue Origin said the first test engine has been installed on a firing stand at Bezos's West Texas test facility for final checks.

Rob Meyerson, president of Blue Origin, said April 5 that the first firing of the test engine would occur "very soon."

According to Bruno, the hotfire tests will eliminate sufficient risk in the engine's development to permit ULA to settle on the BE-4 as the main propulsion system for the Vulcan booster stage.

Despite a delay of several months in the start of full-scale BE-4 testing, Bruno said the Vulcan rocket is still on track for a maiden flight by the end of 2019 if Blue Origin ends up the winner in ULA's engine test-off.

"Assuming we can make this decision in a reasonable span of time, yes," Bruno told reporters on the sidelines of the Space Symposium. "If we're on the BE-4, it's a pretty clear schedule. If the BE-4 is not going to work out and we sel ect AR1, they're further behind, so that puts a little more pressure on that schedule ... If we had to sel ect the AR1, I cannot fly it by 2019."

ULA will introduce the Vulcan launcher in phases, eventually replacing the company's Atlas 5 and Delta 4 rocket fleets in the 2020s.

The first step is developing a new high-power engine to replace the Russian-made RD-180 engine currently flying on the Atlas 5's first stage, followed by work on a new upper stage to replace the Centaur second stage, which is based on a 1960s-era design.

The advanced upper stage will be capable of refueling in space and can generate its own electricity with an on-board fuel cell, allowing it to loiter in orbit for weeks or months to conduct multiple missions as a space tug.

If ULA decides on the BE-4 as the RD-180's replacement, the Vulcan's first stage will be powered by two of the commercially-developed and privately-funded engines, each generating about 550,000 pounds of thrust at full throttle.

The U.S. Air Force last year committed more than $46 million of government funding to partially pay for the cost of accommodating the BE-4 engines on the Vulcan's first stage.

Development of the BE-4 engine itself is a commercial effort, primarily funded by Blue Origin, with additional investment by ULA. Officials have not disclosed the BE-4's development cost, but Bruno said new rocket engines of its scale have typically cost about $1 billion to design, test, and certify.

The Air Force has obligated at least $115 million to the AR1 engine project in a cost-sharing arrangement with ULA and Aerojet Rocketdyne.

ULA engineers are designing two versions of the Vulcan first stage in case company managers pick either of the candidate engines.

Both engines use oxygen-rich staged combustion technology, a technique that minimizes propellant waste during launch. The BE-4 will burn a combination of super-cold liquified natural gas and liquid oxygen, while the AR1 consumes kerosene fuel at room temperature.

In the case of the BE-4, the Vulcan first stage will measure around 16.7 feet (5.1 meters) in diameter. The wider propellant tanks are needed to hold the BE-4's methane fuel, which is less dense than the RP-1 kerosene fuel used by the RD-180 and AR1.

The AR1 variant of the Vulcan launcher would have a first stage closer in design to the Atlas 5, which has a diameter of about 12.5 feet (3.8 meters). The AR1 engine will produce more than 500,000 pounds of thrust at sea level.

Aerojet Rocketdyne says the AR1 is the lowest-risk engine option for the Vulcan and offers the fastest path to end ULA's reliance on Russian engines to send U.S. military payloads into orbit.

Both engine candidates are designed to cost less than similarly-sized U.S.-made rocket engines, such as the RS-68 engine on the Delta 4 rocket and the reusable RS-25 engine built for the space shuttle and now being modified for NASA's huge Space Launch System.

ULA launches the lion's share of U.S. national security satellites, but its hold on the military launch market has loosened with SpaceX now allowed to compete for Pentagon launch contracts.

Bruno said the both versions of the Vulcan will have a lengthened first stage to hold more propellant, taking full advantage of the power of the twin BE-4 or AR1 engines, which will deliver over a million pounds of combined thrust, higher than the 860,000 pounds of thrust fr om the RD-180 engine.

Blue Origin kicked off the design of the BE-4 engine in 2011, and ULA officials previously said the BE-4 development schedule was about two years ahead of the AR1's timeline.

Bruno said Blue Origin originally intended the BE-4 to produce about 400,000 pounds of thrust. The engine was initially conceived for Blue Origin's own orbital launcher, now named New Glenn.

Blue Origin agreed to increase the power of the BE-4 for ULA, Bruno said.

The head start and steady funding stream fr om Bezos, who is now ranked as the second-richest person in the world, give the BE-4 an advantage in the competition with the AR1, Bruno said.

"Normally, when you're developing an engine, you start testing at a relatively low-scale -- 10, 20 sometimes 25 percent -- and you test components, then you jump to full-scale," Bruno said. "Blue was already developing this engine for their New Glenn vehicle when we entered our partnership.

"They were at 400,000 pounds of thrust. We asked them to increase it to 550, which they've done," he said. "But that meant that when we started working together, they already had hardware at 80 percent scale. They finished testing that hardware, and now they're at 100 percent scale."

The AR1 engine's development got a "cold start" when ULA started working with Aerojet Rocketdyne, Bruno said.

"They're still at the sub-scale component level," Bruno said. "They've been testing their preburner, which is like a miniature version of their main engine's combustion chamber that powers the powerpack, so they've been testing that and other components.

"Both of them are doing fine, but they just happen to be in different places on those development timelines," he said.

Meyerson said the BE-4 engine can be recovered and reused up to 100 times. Seven BE-4 engines will propel the company's heavy-lift New Glenn rocket into space.

Engineers contend the methane fuel used on the BE-4 makes it easier to reuse than kerosene-fueled engines like the AR1 and SpaceX's Merlin powerplant, leaving less soot and other contaminants that might need to be cleaned out between flights.

In an update emailed to news media last month, Bezos said Blue Origin's engineers installed new hydrostatic bearings inside the BE-4 turbopump to replace traditional ball and roller bearings, reducing contact between engine parts between startup and shutdown as the the pump produces 70,000 horsepower fr om a turbine spinning at 19,000 rpm.

"Why do we go to all this trouble instead of just using traditional bearings? Engine life," Bezos wrote. "We're relentlessly focused on reusability, and properly designed hydrostatic bearings offer the potential for longer engine life without refurbishment. This is one of the many engineering decisions we've made that we hope will lead to reusability - not just in principle - but to practical, operational reusability."

ULA plans to begin recovering the Vulcan's BE-4 engines, if they are selected, around 2024 using a giant parafoil that can be plucked out of the sky with a helicopter. The first stage structure will crash into the ocean and be discarded.

ULA officials say their approach salvages the engines, which represent about 70 percent of the cost of the first stage, without reserving fuel and adding steering and landing mechanisms for flyback maneuvers like SpaceX's Falcon 9 rocket.

Bruno called SpaceX's reflight of a previously-used Falcon 9 rocket stage March 30 a "tremendous engineering accomplishment."

"The notion of booster recovery has been around for a long time, as well as things like single stage to oribt, which implies recovery, so I think it was a great accomplishment, and I had total confidence that they would get it done," Bruno said.

"The reason you do it is an economic reason," he said. "It's in order to lower the cost of what would otherwise be a fully expendable launch service. The jury is still out on what is the best way to do that. They have a full booster recovey concept. We're working on a concept wh ere we recover just the engines because it turns out two-thirds of the price of that booster is in literally one part -- it's just the engine."

The BE-4 is, by far, the most powerful methane-fueled rocket engine ever built. That adds to the importance of the upcoming ground test campaign in West Texas, according to Bruno.

"Whenever you develop a new liquid rocket engine, if you change the fuel, or if you stay with the same fuel and change the scale of the engine, or if you keep the scale, keep the fuel but change the thermodynamic cycle ... Any one of those three variables can create a situation we call combustion instability," Bruno said.

All three variables are new with the BE-4.

"It's just like if you went out to start your car (in cold weather), you start it up and it idles rough for a few minutes, and then it warms up and everything's cool," he said. "That is actually combustion instability in your car's engine.

"When a rocket engine is sitting there putting out hundreds of thousands of horsepower, those few seconds can tear your engine up," Bruno said. "So it's one of the technical issues we deal with in engine development.

"Blue Origin's engine is methane," he added. "This will the largest scale we've ever done in methane, therefore, combustion instability is an inherent technical risk."

The first sequence of BE-4 hotfire tests will tell engineers if the engine has any such hiccups at startup.

"It's not unusual, by the way, to have some instability when you develop a new engine," Bruno said. "There are tried and true techniques that you apply to smooth that out. If they work right way, you're usually home free. I've never developed an engine that I didn't have to tune, but I have been in situations wh ere you tried the tried and true things, then nothing works, and nine months later you're still stuck. That's the risk we're retiring here."

ЦитатаULA is confident its engine and rocket development efforts will meet the 2022 deadline imposed by the Congress for ending purchases of the RD-180. We're making great progress on Vulcan - the all-American replacement for the venerable Atlas rocket - and have two of the country's best engine companies working on two options for its engine.

 We're making enhancements to Vulcan's Centaur upper stage to add crucial heavy lift capability for the Air Force. That will add about six months to the program's original schedule , but the resulting delay is months, not years, and it's a purpose-driven change to deliver better performance, not a schedule slip.

 The Vulcan-Centaur combination will permit launch of the nation's heaviest satellites to any of the nine reference orbits our national security customers require. Moreover, the enhanced Centaur stage will allow this heavy lift capability without resorting to the costly three-booster configuration of today's "heavy" launch configurations.

ЦитатаApril-May 2017 Updates

First BE-4 Rolls Out at Blue Origin during March, 2017

During mid-April, 2017, ULA President and CEO Tony Bruno confirmed that Vulcan would use 5.4 meter diameter tanks.  The new tanks, fatter than even the Delta 4 tanks, would be fabricated by friction stir welding four orthogrid panels together.  Use of the orthogrid design, replacing the previous isogrid, will play a role in reducing production time by half.

Earlier in the same month, Bruno had confirmed that a final propulsion decision between BE-4 and AR-1 would be made by the end of 2017.  At the time, BE-4 was expected to begin full-scale testing within a few weeks.  The results of that testing would inform ULA's decision.

Blue Origin had rolled-out its first BE-4 engine during March, 2017.  The engine was delivered to the company's Texas test site for full-scale testing.

During May, 2017, Blue Origin suffered a BE-4 "power pack" failure at the company's West Texas test site. The failure appeared to set back development efforts for several months since the expected full-scale BE-4 engine test did not take place "within a few weeks" after its delivery as originally announced.

BE-4 Test 1 (Blue Origin)BE-4 Hot Fire Success

On October 18, 2017, after months of delay following a May 2017 power pack test failure, Blue Origin performed an initial successful hot fire test of its full-scale BE-4 engine.  The engine was fired at 50% thrust for about three seconds at the company's West Texas test facility.

Vulcan Centaur 5

On October 10, 2017, ULA CEO Tory Bruno announced, in a Space News opinion piece, that ULA had decided to modify Vulcan's Centaur stage to meet heavy lift requirements provided in the October 5, 2017 U.S. Air Force EELV Launch Services Agreement RFP. The specification listed payload masses for nine reference orbits. Bruno stated that the change would add about six months to the original program schedule.

Original plans had called for the existing "Centaur 3" stage currently flown atop Atlas 5 to serve as the second stage for an initial Vulcan Centaur variant.

Later, in a question and answer session on Reddit, Bruno revealed that the upgraded stage would be named "Centaur 5" and that it would be 5.4 meters diameter, a substantial increase from the current 3.048 meters. He also noted that while Centaur 5 would bring the heavy lift capabilty forward sooner, the previously-planned ACES stage would still be needed to provide long duration and in-orbit reusability. He said that ACES and Centaur 5 would use the same tooling. He also said that ULA had not yet selected an ACES engine, suggesting that Centaur 5 would still be powered by RL10 engines.

Although ULA had not revealed details of Centuar 5 by month's end, it was clear that the stage would have to carry substantially more propellant than the existing Centaur 3 stage. Such a stage would almost certainly need two or more RL10 engines.

ЦитатаULA feels no schedule pressure to sel ect Vulcan engine
by Jeff Foust (http://spacenews.com/author/jeff-foust/) -- November 10, 2017  

ULA Chief Executive Tory Bruno said there was no "schedule pressure" to sel ect an engine for the company's next-generation Vulcan rocket. Credit: ULA  

WASHINGTON -- The chief executive of United Launch Alliance said Nov. 9 that he doesn't feel any urgency to sel ect a main engine for his company's next-generation Vulcan rocket, despite an impending deadline for an Air Force launch competition.
During a question-and-answer session after his speech at a Washington Space Business Roundtable luncheon, Bruno declined to give an update on the competition between the BE-4 engine from Blue Origin and the AR1 from Aerojet Rocketdyne to power the first stage of the Vulcan.
ULA has long indicted its preferred choice is the BE-4, but wanted to wait until the engine completed a series of test firings to confirm it would be suitable. Blue Origin announced Oct. 19 it had carried out the first hotfire test of the engine, but has not disclosed if it has carried out any additional tests to date. Bruno didn't comment on that test beyond the statement ULA issued at the time congratulating Blue Origin for the achievement.
The test comes as companies face a Nov. 20 deadline to reply to a request for proposals fr om the U.S. Air Force for its Launch Services Agreement program. That effort is designed to support the development of new Evolved Expendable Launch Vehicle-class rockets, including initial launches needed to obtain certification. The Air Force plans to make up to three awards through cost-sharing agreements.
Despite that impending deadline, Bruno said there was no hurry to select an engine, based on assessment of work needed to complete the vehicle in time to meet the Air Force's certification schedules. "I am not concerned about I would say is schedule pressure" for selecting an engine to meet that timeline, he said. "We have time to execute our process."
Bruno also said he was not concerned about getting approvals fr om ULA's two owners, Boeing and Lockheed Martin, to continue development of Vulcan. "We generate our own operating cash and expenses and investment fr om our ongoing business," he said. "Our parents -- our owners -- generously allow us to invest in this new platform rather than simply turn that money back into cash in their pockets."
Bruno declined to specify how much internal investment was going into Vulcan, but noted the company has consistently been profitable. "I might hazard to argue that ULA is one of the very few space launch companies that has consistently earned a reasonable profit," he said.
He reiterated that ULA's approach to reusability for Vulcan remained recovering the first stage engines, rather than landing the entire first stage. That contrasts with SpaceX, which now routinely lands the first stage of its Falcon 9, and Blue Origin, which plans to land the first stage of its upcoming New Glenn orbital launch vehicle.
Bruno said it appeared to ULA that recovering just the engines, which account for most of the value of the stage, made more sense than the entire stage, as in some cases performance requirements for a mission will make it impossible to land the stage. "We're going to find out in the marketplace which is true," he said.

ЦитатаULA taps L3 for Vulcan rocket avionics
by Caleb Henry (http://spacenews.com/author/caleb-henry/) -- December 4, 2017

WASHINGTON -- United Launch Alliance today selected L3 Technologies to provide avionics and related services for its next-generation Vulcan rocket.
L3 expects to provide ULA with more than $1 billion in hardware and serves over the next 10 years, L3 said in a Dec. 4 release.

ULA specified that the avionics are for Vulcan Centaur, the first iteration of the rocket that uses a new first stage paired with the existing Centaur upper stage used on the Atlas 5. The second version of that rocket will have the Advanced Cryogenic Evolved Stage, or ACES, to lift heavier payloads that would go on the Delta 4 Heavy. The first launch of Vulcan Centaur is planned for 2019 (though the company has yet to downselect either Blue Origin's BE-4 or Aerojet Rocketdyne's AR1), followed by Vulcan ACES in 2023.

"United Launch Alliance is proud to select L3 to develop the complete avionics package for our Vulcan Centaur launch systems," said ULA President and CEO Tory Bruno. "We have exceptional confidence in the quality, performance and value of L3's avionics design, which will give our customers even greater capability for new missions at a significant reduction in cost."

L3's Sensor Systems division will supply the avionics equipment, which L3 and ULA will collaboratively integrate into Vulcan's design and manufacturing processes.

STORY WRITTEN FOR CBS NEWS (http://www.cbsnews.com/) & USED WITH PERMISSION

SpaceX and its visionary founder Elon Musk win the lion's share of public attention in the commercial rocket arena, with dramatic, increasingly routine booster landings and spectacular stunts like the launch of Musk's Tesla Roadster on the maiden flight of the company's new Falcon Heavy rocket last month.

But arch-rival United Launch Alliance, a much more buttoned-down corporate alliance between Boeing and Lockheed Martin, is responding to the threat posed by the upstart SpaceX with long-range plans to phase out its workhorse Atlas 5 rocket and costly Delta 4 rockets in favor of a powerful, less-expensive launcher known as the Vulcan.

Featuring reusable engines and an advanced, long-lived upper stage, company executives expect the Vulcan to be a major contender in the increasingly fierce slugfest between SpaceX, ULA and other international launch providers.

That battle was center stage Wednesday when the Air Force awarded SpaceX a $290 million contract to launch three Global Positioning System navigation satellites atop Falcon 9 rockets in late 2019 and 2020.

At the same time, ULA won a $351 million contract to launch two Space Situational Awareness Program satellites using an Atlas 5 rocket in 2020, along with a second flight to launch another pair of military payloads.
"I am a big supporter of competition," ULA CEO Tory Bruno said in a recent interview. "Makes it an exciting time to be in space, you never know what's going to happen. In my 35 years as a rocket scientist I never thought I'd see somebody just launch a car into space for fun. I'm not sure what I think of that yet. So yeah I'm with you. These are exciting times."

In one sense, ULA is playing the tortoise to SpaceX's hare. Musk was first out of the blocks with development of reusable rocket boosters, but Bruno believes ULA's Vulcan, with reusable first stage engines, makes the most sense financially given current market projections.

He said the Vulcan's engines represent two-thirds of the cost of the stage. Under ULA's approach, the engines will be recovered and reused after every flight. SpaceX's design calls for recovery of the entire rocket stage. Depending on the weight of the payload and the requirements of its orbit, that cannot be done on every flight.

"It boils down to as simple as this: is it better to recover 100 percent of the value of the booster some of the time or only two thirds of the value of the booster all of the time?" Bruno said reporters during a roundtable discussion earlier this week.

"Well, that depends on how often you get a big, heavy payload. We've each made market forecasts, and if we're right, our solution will be economically advantageous. If I'm wrong and they're right, then theirs will."

ULA is staking its future on the Vulcan. Equipped with up to six upgraded strap-on solid-fuel boosters, the new rocket will generate some 3.8 million pounds of liftoff thrust.

Out-performing ULA's current heavy lift booster, the three-core Delta 4, the Vulcan will be able to boost 80,000 pounds to low-Earth orbit or up to 35,900 pounds to the elliptical geosynchronous transfer orbits -- GTOs -- used by communications satellites bound for operational stations 22,300 above the equator.

The least powerful version of the new rocket, one without any solid-fuel boosters and an advanced upper stage known as ACES, is expected to sell for less than $100 million. The base version of ULA's Atlas 5 rocket currently goes for about $109 million, Bruno said, while a heavy lift Delta 4 sells for about $350 million.

Even with six solid-fuel boosters and a large payload fairing, the most powerful version of the Vulcan will still cost "more like a quarter or a third of the cost of the Delta 4 Heavy," Bruno said in the interview with CBS News.

For comparison, SpaceX sells a commercial version of its Falcon 9 rocket for $62 million, according to the company's website, although the price climbs to more than $90 million a copy for military missions.

A commercial version of the company's Falcon Heavy rocket, which debuted in February, has a list price of $90 million, but that apparently assumes all three core stages are recovered for reuse. That version of the rocket, according to the SpaceX website, can boost eight metric tons, or 17,600 pounds to geosynchronous transfer orbit.

That's the version launched last month, roughly equivalent, Bruno said, to a "mid-range Atlas." A fully expendable version of the Falcon Heavy can lift nearly 59,000 pounds to that same orbit, easily making it the most powerful rocket in the world.

Bruno said he was impressed by the Falcon Heavy and SpaceX's maturing ability to recover spent rocket stages.

"I'm a rocket scientist, and that was very cool to watch," he said. "I certainly give credit to Elon Musk for sort of creating more excitement around space than we had a decade ago."

But this is not a particularly friendly competition. SpaceX's website brags the Falcon Heavy "can lift more than twice the payload of the next closest operational vehicle, the Delta IV Heavy, at one-third the cost."

Not so fast, says Bruno.

"Delta Heavy was really designed around the national security, primarily NRO (National Reconnaissance Office) mission set, which has complicated orbits, and it's optimized for that," he said. "It goes for about $350 million. It's a military mission only, I don't offer it commercially, at least today, there's no commercial market for a Heavy."

The Delta 4, designed by Boeing, and the Atlas 5, built by Lockheed Martin, originally were developed for the Air Force as "evolved expendable launch vehicles," or EELVs, intended to provide assured access to space for high-priority national security payloads.

With government approval, the two companies formed a partnership and the first Atlas 5, carrying a commercial satellite, blasted off in August 2002.

SpaceX launched its first Falcon 9 in 2010 and, after Air Force certification and vocal complaints about ULA's perceived monopoly in the military space arena, the California rocket builder was cleared to compete for military contracts.

"We've been competing now for almost two years in the military market space," Bruno said before this week's Air Force contracts were announced. "Falcon 9s are going for about $97 million, $96.5 million, I think, is the most recent one. They've won half, we've won half. The government discloses the winner's price because we're public procurements. So I think we each know what our prices are."

To compare the Falcon Heavy with the Delta 4, "you want to compare government missions," he said. "We don't market (the Delta 4) commercially. So I would look at the Falcon 9 at $96.5 million as a single stick. Scale that up to be a Falcon Heavy, which is a three-core version of that rocket, and whatever that price is is what I would compare to $350 million.

"If you want to take a massively large payload to LEO (low-Earth orbit), that would be the rocket that would do it. If you want to go higher, you might want to fly on a Delta 4."

But a Falcon Heavy is not made up of three Falcon 9s. It is, more accurately, one Falcon 9 with a modified central stage and two additional Falcon 9 core stages.

SpaceX has said a fully expendable version of the Falcon Heavy, one capable of boosting nearly 59,000 pounds to GTO, would cost around $150 million, less than half the cost of a Delta 4 Heavy.

But ULA says a rocket's cost is just one factor in a sale. The company also is selling reliability and "schedule certainty."

ULA has launched 76 Atlas 5 rockets and 36 more expensive Delta 4s without a single failure. SpaceX has suffered one catastrophic in-flight failure in 50 Falcon 9 launches to date and one on-the-pad explosion.

A rocket's reliability affects insurance rates and meeting a promised launch date means a commercial satellite will start generating revenue as soon as possible. ULA says both of those factors act to reduce the actual cost of a launch on one of its rockets.

Another wild card in the equation is SpaceX's plan to build an even more powerful rocket known as the BFR, for Big F-ing Rocket, intended for eventual missions to Mars. It is not yet clear where the Falcon Heavy fits into the company's long-range plans or whether the BFR will be used for the sorts of payloads ULA hopes to launch on its Vulcan.

But the Delta 4-Falcon Heavy debate will be moot soon enough as ULA phases out the Delta 4 and the Atlas 5 in favor of the Vulcan. Bruno said "at least" seven to eight more Delta 4s will be launched between now and the early 2020s while the Atlas 5 likely will fly into the mid 2020s, overlapping with the Vulcan program as the new rocket begins operational flights.

In the meantime, the Atlas 5 also will be used to launch Boeing's CST-100 commercial crew ship on flights to ferry astronauts to and from the International Space Station. SpaceX also holds a NASA contract to develop a piloted version of its Dragon cargo ship that will launch atop a Falcon 9. Both companies hope to begin routine flights to the station next year.

The maiden flight of the Vulcan currently is targeted for the middle of 2020. Two successful commercial launches are required as part of the government certification process, followed by a required upper stage upgrade to improve performance, either Aerojet Rocketdyne RL10 engines or a different set of engines altogether.

If all goes well, ULA will introduce its new upper stage in 2024, the Advanced Cryogenic Evolved Stage, or ACES, that Bruno says will revolutionize spaceflight.

"This is on the scale of inventing the airplane," Bruno told reporters during the media roundtable. "That's how revolutionary this upper stage is. It's 1900, and I'm inventing the airplane. People don't even know what they're going to do with it yet. But I'm confident it's going to create a large economy in space that doesn't exist today. No one is working on anything like this."

The Vulcan will stand 228 feet tall with a first stage powered by two engines provided by either Blue Origin, a company owned by Amazon-founder Jeff Bezos, or Aerojet Rocketdyne. Blue Origin's BE-4 engine burns methane and liquid oxygen while Aerojet Rocketdyne's AR-1 powerplant burns a more traditional mixture of oxygen and highly refined kerosene.

Both engines will generate between 500,000 and 550,000 pounds of thrust and two will be used to power the Vulcan's first stage. Bruno said ULA is nearing a decision on which engine to employ but would not provide any sort of timetable other than to say the company would announce its choice "soon."

"They're both good engines," he told CBS News. "They both use the what we think of as a very advanced Russian engine cycle, an oxygen-rich stage combustion that the U.S. has never, ever had, and we now will. They just use two different hydrocarbon fuels as you know, one is kerosene and one is methane."

Both engines "have a lot of additive manufacturing content, which takes that Russian technology and makes it a lot more manufacturable and really updates it to modern standards. So they were both good engines. They are both, you know, hitting their marks and wh ere they planned to be. That's probably all I can say."

Whichever engines are used, the Vulcan first stage is being designed with reusability in mind. But unlike SpaceX, which can recover it's Falcon 9 first stage intact with a rocket-powered return to landing on shore or on an off-shore droneship, ULA only plans to recover the Vulcan's first stage engines.

ULA plans to begin engine recovery operations after the Vulcan is routinely flying and after the ACES upper stage is implemented.

Bruno said the engines represent two-thirds of the cost of the stage and getting them back every time, with no impact on mission performance, will pay big dividends. SpaceX, in contrast, must use propellant to fly its Falcon 9 stages back to touchdown. Heavy payloads bound for high orbits require most if not all of the rocket's propellant and in those cases, recovery may not be possible.

As a result, SpaceX's ability to recover rocket stages depends on its manifest and the orbital demands of those payloads.

"Simplistically, if you recover the old booster propulsively then you can do that part of the time, you get all the value back some of the time," Bruno said. "Or, you can recover just the engine, which is our concept, and then you get only part of the value back, about two thirds ... but you get to do it every single time because there's no performance hit. So it really turns into math."

And that math is based on market projections about future satellite builds and the percentage of heavy-weight payloads ULA expects to be launching.

"We've made a forecast of what we think the future marketplace will be and said engine recovery is more financially attractive," Bruno said. "I think SpaceX has made different calculus. And we'll both go to the market and find out who's right."

To recover the Vulcan engines, a small pod housing an inflatable heat shield and a gas generator will be mounted on the bottom of the first stage. After boosting the rocket out of the lower atmosphere, the engines will shut down and the propulsion section will be disconnected, allowing it to fall free.

The heat shield, based on NASA technology, then will inflate using the gas generator, protecting the engines from the heat and stress of atmospheric entry. Once clear of the plasma heating region, a parafoil will deploy to fly the engines to their planned pickup point.

A large helicopter then will swoop overhead, snagging a cable to capture the engine package, which will be lowered to the deck of a nearby salvage ship. A similar technique was used to capture film canisters ejected from Corona spy satellites in the 1960s.

"We'll separate really the whole back end (of the first stage)," Bruno said. "Then, we're going to re-enter it behind the NASA inflatable heat shield and then pop a parachute, really a parafoil, because that allows us to make sure we fly to GPS coordinates and a big helicopter will be waiting for it and snag it set it down."

Recovering the engines non-propulsively will allow the Vulcan to use virtually all of its propellant to put the payload into the best possible orbit "for a pretty modest weight penalty, you know, the weight of a parachute, the weight of the subsystem," Bruno said.

For a booster, five pounds of inert weight only costs one pound of payload, he added, whereas it's pound for pound on an upper stage.

In any case, Bruno said the entry environment behind the heat shield is much more benign than what a Falcon 9 experiences with its tail-first propulsive descent and ULA engineers expect engine refurbishment to be a relatively straight forward affair.

"The engines that we're developing we think are going to be pretty easy to refurbish," Bruno said. "What we think we're going to do is get them back, inspect them, for the first few times we'll likely hot fire them to make sure we know how they're behaving. If they're behaving the way we expect, we'll probably stop doing that. We'll just clean them up, inspect them and use them."

Along with recoverable first stage engines, the Vulcan first stage features redesigned plumbing with an internal liquid oxygen feed line, freeing up real estate on the side of the rocket for a sixth strap-on solid-fuel booster.

The Vulcan will be marketed in a variety of configurations depending on payload requirements. If all six SRBs are used, liftoff thrust will be 3.8 million pounds, out performing the Delta 4.

ULA has not yet announced which company will provide the upper stage engines used for the rocket's initial flights before a planned performance upgrade. But the company expects to introduce the ACES upper stage in 2024.

Featuring up to four hydrogen-fueled rocket engines, ACES will carry three times the propellant of current ULA upper stages, will be able to operate for weeks or months at a time and will enable complex orbital operations near Earth, the moon or beyond.

The keys to its performance are ultra lightweight propellant tanks and dual "straight-six" internal combustion engines mounted on the bottom of the stage burning gaseous oxygen and hydrogen produced by the normal "boil off" of propellants in the main tanks.

The 1,000-cc engines, under development at Roush Fenway Racing, will be used to pressurize the propulsion system, push propellants to attitude control jets and generate electrical power, allowing ULA to replace multiple systems with a single solution.

"In a conventional stage, you've got to have electrical power, so you have big, long-duration batteries," Bruno said. "You have to have an attitude control system, so you have typically an entirely separate propulsion system, usually hydrazine. And then you need to pressurize your propellant, which you use (helium) to do."

Such stages typically have lifetimes measured in hours because the supercold propellants are continually boiling off into gas and batteries lose their power.

ACES solves those problems by using the internal combustion engines to accomplish all of those tasks over an extended period.

"The engine has a generator on it just like your car does so you don't need the batteries anymore," Bruno said. "And we're using the power that comes off of that internal combustion engine to run a compressor and a heat exchanger ... that's putting energy back into the gases. We pipe them back up into the tank and that pressurizes the tanks. So we don't need helium at all anymore."

Or heavy time-limited batteries.

"Each one of these (generators) throws off about 60 kilowatts," Bruno said. "We run a Centaur (stage) at about 10 watts. So now you've got 120 kilowatts of electrical power that you could use for other things."

And the same waste hydrogen and oxygen burned by the engines also can be used to power the stage's attitude control thrusters, eliminating the need for a separate propulsion system using toxic hydrazine.

"So as long as you've got all of this gaseous hydrogen and gaseous oxygen you have propellant," Bruno said. "So we've also developed (oxygen-hydrogen) thrusters and we've been testing those as well. They provide the attitude control and ... that allows us to delete the entire hydrazine system.

"So that's how it works. We've probably got, I'd say 300, 350 tests on that engine now. It's pretty cool."

ЦитатаAir Force stakes future on privately funded launch vehicles. Will the gamble pay off?
by Sandra Erwin (http://spacenews.com/author/sandra-erwin/) -- March 25, 2018

Analyst Bill Ostrove: Vulcan's first flight has slipped from 2019 to 2020. "The engine choice will affect the design of the entire rocket."

WASHINGTON -- The schedule is getting tight for the U.S. Air Force as a 2022 deadline looms to bid farewell to the Atlas 5 and switch to a different rocket that is not powered by a Russian engine.

The target date was mutually agreed by Congress and the Air Force in 2016, allowing what was considered sufficient time to find alternatives to the United Launch Alliance's Atlas 5 that uses the Russian RD-180 engine. The solution they settled on was for the Air Force to sign deals with the space industry to co-finance the development of new rocket propulsion systems.
The program known as the "launch service agreement" fits the Air Force's broader goal to get out of the business of "buying rockets" and instead acquire end-to-end services from companies.

The Air Force signed cost-sharing partnerships with ULA, SpaceX, Orbital ATK and Aerojet Rocketdyne. The original request for proposals noted the Air Force wants to "leverage commercial launch solutions in order to have at least two domestic, commercial launch service providers."

The next step is to sel ect three companies this summer to move forward with enginet prototypes.

"We are on schedule to make LSA awards in July 2018," a spokesman for the Air Force Space and Missile Systems Center told SpaceNews.

The sel ected competitors will face a schedule that seems ambitious even by the standards of commercial space companies.

ULA's CEO Tory Bruno called the launch service agreement a "pretty rational" approach that puts the onus on the private sector.

As the operator of the Atlas 5 rocket, ULA will come under enormous scrutiny as it moves to develop its replacement, the Vulcan Centaur vehicle. Although the Atlas 5 will continue to be sold commercially, without the ability to offer Atlas 5 to the military after 2022, the future of ULA rests on Vulcan.

Which explains why there is so much anticipation about what engine ULA will sel ect for the reusable first stage of the Vulcan Centaur. It is considering either the BE-4 made by startup Blue Origin or the AR-1 designed by established military contractor Aerojet Rocketdyne. The new first stage would be paired with the existing Centaur upper stage from the Atlas 5. A decision was expected months ago, and Bruno has said recently that it is "coming soon."

Asked about the implications of the delayed engine selection on the LSA program, the Air Force Space and Missile Systems Center spokesman said officials would not comment on an ongoing source selection.

During a recent talk with reporters, Bruno predicted ULA would be able to meet the LSA timelines regardless of what engine is picked. From the government's perspective, the risk lies in the fact that private industry is "bringing most of the money," he said. "That's always what governs a big complicated aerospace development program -- being funded."

The good news for the government is that there are multiple bidders, Bruno said. "That bodes well, that means the government has choices."

Vulcan Centaur is 75 percent privately funded, Bruno said. To remain a contender in the LSA program, it needs to be ready for certification flights by 2020. ULA has agreed to two non-government flights to certify Vulcan for national security missions. The certification could happen as early as 2020 or early 2021.

"We feel very confident about our schedule and our plan to achieve that whole timeline," he said.

The engine choice has kept the industry in suspense. (http://spacenews.com/be-4-engine-tests-continue-as-ula-waits-to-make-vulcan-engine-decision/)

The Blue Origin engine is further along in development than the AR-1, although there are other issues to consider. "If we were to select AR-1 that puts more pressure on the schedule," said Bruno. "But it does not necessarily invalidate the LSA requirements. I have much less schedule margin if I choose AR-1. But I could still meet the timelines."

Some companies in the LSA program are partners and rivals at the same time. Orbital ATK will compete with its own rocket but it also has invested in the development of the Vulcan solid rocket booster. There is speculation that Blue Origin could also jump into the LSA fray with its New Glenn rocket.

"Having a competitor in my supply chain ... Absolutely that is considered carefully," said Bruno. "That is not unusual in our industry." Orbital ATK is not only a competitor and major supplier to ULA but also a ULA customer for cargo missions to the International Space Station.

Orbital ATK has made a "substantial investment in developing that component for Vulcan," he noted. "The supplier in this case is investing their own money. In exchange we give them a long-term contract that allows us to have stability in pricing."

Blue Origin is investing a "considerable amount," he said. "To a lesser degree Aerojet Rocketdyne is investing their own funding in AR-1." The engines are the most expensive parts of the rocket, accounting for two-thirds of the cost of the booster.

Timeline too ambitious?

William Ostrove, aerospace and defense analyst at Forecast International, noted that ULA has been on the verge of picking a winner "for a long time."

Vulcan's first flight has slipped fr om 2019 to 2020, said Ostrove. "The engine choice will affect the design of the entire rocket. A decision has to be made if the Air Force is going to stick to the plan" of phasing out the Atlas 5 by 2022.

The delay could be adding risk to the Air Force LSA strategy, Ostrove said. For the program to succeed, launch contractors need to have both government and commercial business. "If there is no market for these large launch vehicles then the Air Force may have to step in and provide more funds." That is exactly what the Air Force had to do more than a decade ago with Atlas 5 and Delta 4, which were originally intended as dual use.

A contrarian view comes fr om the defense industry establishment. Loren Thompson, of the Lexington Institute -- a think tank that receives funding fr om ULA owners Boeing and Lockheed Martin, Aerojet and other defense firms -- has called on the Air Force to keep the Atlas 5 and swap the RD-180 engine for Aerojet Rocketdyne's AR-1 rather than develop a new launch vehicle.

"In an effort to save time and money, they accept greater risk," Thompson told SpaceNews. "In an attempt to spur innovation, they turn to untested commercial products and practices. This approach was an utter failure in the 1990s, and yet we are gradually backing into the same errors again."

Air Force Secretary Heather Wilson has expressed confidence in the LSA approach.

"We are cost sharing with companies as they develop alternatives to the Russian engine," she told reporters last month on Capitol Hill. "We are doing that intentionally. We need a couple of options. It's a risky business," Wilson said.

The program is moving forward as planned, she said. "Usually if they haven't walked in and said, 'Houston we've got a problem,' it means it's continuing on, on schedule."

ЦитатаUnited Launch Alliance Selects Aerojet Rocketdyne's RL10 Engine for Next-generation Vulcan Centaur Upper Stage

Centennial, Colo., May 11, 2018 - United Launch Alliance (ULA) today announced Aerojet Rocketdyne as a strategic partner for the RL10 upper stage engine for ULA's next-generation Vulcan Centaur rocket following a competitive procurement process.
"ULA and Aerojet Rocketdyne have a long and successful history together that began with the first flight of our Atlas and Delta rockets in the 1960s," said Tory Bruno, ULA president and CEO. "We could not be more pleased to have selected the proven and reliable RL10 to power our Vulcan Centaur upper stage."

This partnership is a long-term agreement for Aerojet Rocketdyne to provide upper stage propulsion for the next decade. As part of this partnership, Aerojet Rocketdyne will provide RL10s and develop the RL10C-X, the next generation of the RL10 family. The RL10C-X will increase the use of additive manufacturing and introduce other advanced technologies to improve the quality, reliability, affordability and performance.

"Key determining factors to our selection included price and delivery schedule," said Bruno. "We look forward to continuing our strong partnership to ensure a successful introduction of Vulcan Centaur."

Over the course of nearly 60 years, more than 450 RL10 engines have flown on various ULA heritage vehicles with an unmatched record of mission success.

ULA continues its competitive procurement process for the booster engine and plans to make a down select soon.

With more than a century of combined heritage, United Launch Alliance is the nation's most experienced and reliable launch service provider. ULA has successfully delivered more than 125 satellites to orbit that provide critical capabilities for troops in the field, aid meteorologists in tracking severe weather, enable personal device-based GPS navigation and unlock the mysteries of our solar system.

Blue Origin (https://www.youtube.com/channel/UCVxTHEKKLxNjGcvVaZindlg)

Опубликовано: 27 сент. 2018 г.

The BE-4 is our fourth-generation liquid rocket engine, made to take us into orbit and beyond.

The BE-4 uses oxygen-rich staged combustion of liquid oxygen and liquefied natural gas to produce 550,000 lbs. of thrust. Liquefied natural gas is commercially available, affordable, and highly efficient for spaceflight. Unlike other rocket fuels, such as kerosene, liquefied natural gas can be used to pressurize a rocket's propellant tanks. This is called autogenous pressurization and eliminates the need for costly and complex pressurization systems, like helium. Liquefied natural gas also leaves no soot byproducts as kerosene does, simplifying engine reuse.

United Launch Alliance has selected Blue Origin's BE-4 as the engine that will power the Vulcan rocket's first stage. The announcement ends the need for the Russian made RD-180 on their next-generation vehicle Vulcan with the American-made BE-4.

ТТУ заметно дешевле с учетом времени на отработку, позволяют сделать систему с разной суммарной тягой на ряд типовых ПН по массе, для пилотируемых полетов проще обеспечить требуемую надежность.

ULA Selects Blue Origin Advanced Booster Engine for Vulcan Centaur Rocket System

Centennial, Colo., Sept. 27, 2018  - United Launch Alliance's (ULA) next-generation rocket - the Vulcan Centaur - is making strong progress in development and is on track for its initial flight in mid-2020. The Vulcan Centaur rocket design leverages the proven success of the Delta IV and Atlas V launch vehicles while introducing advanced technologies and innovative features. 

"Vulcan Centaur will revolutionize spaceflight and provide affordable, reliable access to space for our current and future customers," said Tory Bruno, ULA's president and CEO. "We are well on our way to the introduction of Vulcan Centaur - the future of U.S. rocket manufacturing. With state-of-the-art engineering and manufacturing techniques, this rocket is designed specifically for low recurring cost."

The new rocket design is nearing completion, and the booster preliminary design and critical design reviews have been completed. Vulcan Centaur will have a maximum liftoff thrust of 3.8 million pounds and carry 56,000 pounds to low Earth orbit, 33,000 pounds to a geo-transfer orbit and 16,000 pounds to geostationary orbit with greater capability than any currently available single-core launch vehicle.

"Our new rocket will be superior in reliability, cost and capability - one system for all missions," said Bruno. "We have been working closely with the U.S. Air Force, and our certification plan is in place."

Following completion of a competitive procurement, ULA has selected Blue Origin's BE-4 engine for Vulcan Centaur's booster stage. The liquefied natural gas (LNG) fueled booster will be powered by a pair of BE-4 engines, each producing 550,000 pounds of sea level thrust. As previously announced, ULA has selected Aerojet Rocketdyne's RL10 engine for the Centaur upper stage, Northrop Grumman solid rocket boosters, L‑3 Avionics Systems avionics, and RUAG's payload fairings and composite structures for the new Vulcan Centaur rocket system.
"We are pleased to enter into this partnership with Blue Origin and look forward to a successful first flight of our next-generation launch vehicle," said Bruno.

"We are very glad to have our BE-4 engine selected by United Launch Alliance. United Launch Alliance is the premier launch service provider for national security missions, and we're thrilled to be part of their team and that mission," said Blue Origin CEO Bob Smith. "We can't thank Tory Bruno and the entire United Launch Alliance team enough for entrusting our engine to powering the Vulcan rocket's first stage."

Vulcan Centaur will bolster U.S. manufacturing by adding to the more than 22,000 direct and indirect American jobs in 46 states supported by ULA programs.

"ULA has chosen the best systems available to create the Vulcan Centaur," said Bruno. "These engines and components will ensure ULA continues to lead the way in space exploration, maintain our record of success and remain America's launch vehicle for our nation's most vital missions."

Vulcan Centaur is ULA's next-generation, American rocket system. As a result of these agreements, the Vulcan Centaur will surpass current rocket capabilities and launch services at significantly lower costs, while still meeting the requirements of ULA's cooperative research and development agreement with the U.S. Air Force to certify the Vulcan Centaur for national security space missions.

"Strong partners are critical to the cutting-edge innovation that is leading us into the next generation in space and ensuring mission success," said Bruno. "Partnerships with Blue Origin, Aerojet Rocketdyne, Northrop Grumman, L-3 Avionics Systems and RUAG will allow the Vulcan Centaur to transform the future of space launch for the government and commercial markets, making launch more affordable, accessible and commercially available."

With more than a century of combined heritage, ULA is the world's most experienced and reliable launch service provider. ULA has successfully delivered 130 satellites to orbit that provide Earth observation capabilities, enable global communications, unlock the mysteries of our solar system, and support life-saving technology.

Ending months of speculation, Blue Origin, a company owned by Amazon-founder Jeff Bezos, has won a milestone contract to provide first-stage rocket engines for a powerful new booster being designed by United Launch Alliance to replace its current fleet of Atlas and Delta launchers, the companies announced Thursday.

Powered by liquefied natural gas and liquid oxygen, Blue Origin's BE-4 engine was sel ected over Aerojet Rocketdyne's more traditional kerosene-burning AR1 for use in ULA's new Vulcan rocket, expected to make its first flight in the mid-2020 timeframe.

"Big win for @BlueOrigin today!" Bezos tweeted. "And a big thank you to @ulalaunch for choosing our BE-4 engine. Excited to be a part of Vulcan's mission to space."

The BE-4 engine will eventually end ULA's reliance on Russian-built RD-180 first-stage engines currently powering the first stage of the company's workhorse Atlas 5. RD-180s burn kerosene and oxygen and develop 860,000 pounds of thrust at sea level.

Two BE-4 engines, generating 550,000 pounds of thrust each, will power the Vulcan's first stage, along with strap-on solid-fuel boosters provided by Northrup Grumman as required by payload weight and trajectory. Maximum liftoff thrust will be 3.8 million pounds and the rocket will be partially reusable.

Aerojet Rocketdyne hydrogen-fueled RL10 engines will power the Vulcan's second stage when the initial version begins operations. A more powerful upper stage, the Advanced Cryogenic Evolved Stage, or ACES, will be phased in later.

ULA plans to continue launching Atlas 5s well into the early 2020s while the Vulcan transition proceeds. The Atlas 5 will be used as planned to launch Boeing's CST-100 Starliner commercial crew capsule to ferry astronauts to and from the International Space Station starting next year.

"We are pleased to enter into this partnership with Blue Origin and look forward to a successful first flight of our next-generation launch vehicle," ULA CEO Tory Bruno said in a statement.

Blue Origin CEO Bob Smith added: "United Launch Alliance is the premier launch service provider for national security missions, and we're thrilled to be part of their team and that mission. We can't thank Tory Bruno and the entire United Launch Alliance team enough for entrusting our engine to powering the Vulcan rocket's first stage."

United Launch Alliance is a partnership between Boeing, original builder of the Delta family of rockets, and Lockheed Martin, developer of the Atlas 5, that was formed primarily to provide assured access to space for high-priority national security payloads

Blue Origin also plans to use the BE-4 in the first stage of its New Glenn rocket, which will compete with both SpaceX and ULA launchers when it debuts in the early to mid 2020s. The New Glenn first stage is designed to land vertically for refurbishment and reuse.

A two-stage version of the New Glenn booster will stand some 27 stories tall and will generate 3.85 million pounds of thrust at liftoff using seven BE-4 engines. The second stage will be powered by two BE-3 engines.

The BE-3 already is in use with Blue Origin's sub-orbital New Shepard rocket, designed to carry tourists, researchers and small payloads to the edge of space and back from a launch site in Texas.

The company has built a huge manufacturing facility near the Kennedy Space Center in Florida to assemble New Glenn rockets, which will be launched fr om nearby Cape Canaveral. Bezos has said he is spending roughly $1 billion a year on his space ventures.

Bezos and Bruno announced an initial agreement to develop BE-4 engines for ULA rockets in September 2014.

"I think it's pretty clear it's time for a 21st century booster engine," Bezos said at the time. "The great engines of the past were truly remarkable machines in their own right ... but we have tools and capabilities, software simulations, computational horsepower that the builders of those great engines could have only dreamed about.

"We can build an engine today that is a 21st century engine that has great reliability, low cost of operations and high performance," he said. "And we're super excited about that, and we couldn't be more excited to have a partner like ULA."

But Aerojet Rocketdyne threw its hat into the ring with plans to develop the AR1, generating 500,000 pounds of thrust, and it soon became clear Blue Origin no longer had a lock on the engine selection. That fueled intense speculation across the space industry about how the competition might play out.

In any case, the selection of Blue Origin's BE-4 means ULA will be relying on an eventual competitor to provide the engines needed for its next-generation rocket. Contract details were not revealed, but it presumably includes delivery guarantees that meet ULA's approval.

"It is a great day for the Blue Origin team!" the company tweeted late Thursday. "We are honored @ulalaunch has selected Blue's LOX/LNG BE-4 engine to power the Vulcan rocket's first stage."

ULA's decision to replace its Delta and Atlas rockets with a single system came in the wake of widely publicized complaints fr om SpaceX founder Elon Musk that criticized the use of the Russian-built RD-180 to launch U.S. national security payloads and what he viewed as a ULA military launch monopoly.

Musk also criticized the high cost of the heavy-lift Delta 4, which uses Aerojet Rocketdyne RS-68 first stage engines and is currently the most powerful fully operational rocket in the U.S. inventory. It also is the most expensive and is used exclusively for national security and NASA payloads.

Musk eventually won the right to bid on high-value military payloads and since then, competition between SpaceX and ULA has been fierce, with ULA trimming costs and arguing its unblemished launch record, presumably lower insurance rates and schedule reliability make up for a higher price tag for the Atlas 5 compared to SpaceX's Falcon 9.

But Falcon 9s cost tens of millions less than the Atlas 5, an obvious selling point in the commercial launch industry. The eventual cost of the Vulcan is not yet known.

"From low Earth orbit to Pluto, the single-core Vulcan Centaur does it all," ULA says on its website. "This simple design is more cost-efficient for all customers, whether defense and national security, NASA science and human spaceflight, or commercial."

ЦитатаNASA, ULA find launch opportunity for inflatable heat shield demonstrator
May 13, 2019 (https://spaceflightnow.com/2019/05/) | Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

A flight demonstration of an inflatable heat shield that could be used to retrieve reusable engines from United Launch Alliance's next-generation Vulcan rocket, and for the delivery of heavier cargo to the surface of Mars, is planned for launch in late 2021 or early 2022 as a piggyback payload on an Atlas 5 rocket with a NOAA weather satellite.

The inflatable re-entry decelerator will launch as a joint project between NASA and ULA, which foresee different uses for the technology.

ULA aims to recover engines from the company's new Vulcan rocket, set to debut in 2021, using an inflatable heat shield and a parafoil. A helicopter equipped with a boom will snag the parafoil in a mid-air recovery, preventing contamination from salt water if the engines splashed down in the ocean.

The inflatable heat shield is much lighter than a rigid heat shield, such as thermal protection systems used on crew capsules, and take up less volume inside a rocket's payload fairing. The technology will allow future NASA missions to deliver more massive rovers, landers, and eventually human-rated habitats to the Martian surface.

The heaviest spacecraft ever landed on Mars using current technology was the Curiosity rover, which weighed less than a ton at touchdown in 2012.

Inflatable heat shield technology could also protect materials manufactured in space during the return trip to Earth.

"It has the potential for returning substantial mass back to Earth," said Jim Reuter, associate administrator of NASA's space technology mission directorate, during an April 30 meeting of the NASA Advisory Council's technology, innovation and engineering committee.

The Low Earth Orbit Flight Test of an Inflatable Decelerator will test a nearly 20-foot-diameter (6-meter) heat shield, the largest blunt body atmospheric entry vehicle ever flown in space.

NASA and ULA have identified room for the re-entry testbed, known by the acronym LOFTID, as a secondary payload on an Atlas 5 launch in late 2021 or early 2022 from Vandenberg Air Force Base, California, with NOAA's Joint Polar Satellite System-2, or JPSS 2, weather observatory heading for polar orbit, according to Reuter.

Officials said NOAA recently agreed to launch the LOFTID experiment with the JPSS 2 satellite, after a search for excess capacity on Atlas 5 missions launching from Vandenberg over the next few years.

Therese Griebel, deputy associate administrator for programs in NASA's technology division, said a recent review with JPSS 2 program managers concluded the addition of the LOFTID experiment on the launch would add no significant risk to the mission.

"It looks like we've gotten everybody on-board (with launching LOFTID with JPSS)," Reuter said.

The JPSS 2 satellite has a targeted launch readiness date in the first quarter of fiscal year 2022, or late in the calendar year 2021, according to John Leslie, a NOAA spokesperson.

NASA, which provides launch and spacecraft development support to NOAA's weather satellites, sel ected ULA's Atlas 5 rocket in 2017 to carry the JPSS 2 spacecraft into orbit. The lightest version of the Atlas 5 rocket, a variant known as the Atlas 5-401 without any solid rocket boosters, will launch the JPSS 2 satellite.

But JPSS 2 fills less than half of the Atlas 5-401's capacity to the weather satellite's 512-mile-high (824-kilometer) orbit, leaving ample room for secondary payloads.

Last year, NOAA released a request for information soliciting ideas for small commercial Earth observation satellites that could ride piggyback on the JPSS 2 launch. With agreement from NASA, NOAA and ULA, part of the excess capacity on the Atlas 5 rocket will be filled with the LOFTID experiment.

The LOFTID re-entry vehicle will weigh around 2,700 pounds (1,224 kilograms).

Under the terms of a no-funds-exchanged Space Act Agreement, NASA will provide the re-entry vehicle and its inflatable aeroshell. ULA will supply the high-pressure tanks to inflate the heat shield in space and the Atlas 5 launch services at no cost to NASA.

NASA's Langley Research Center in Virginia heads the agency's work on the LOFTID experiment.

NASA awarded ULA a separate $1.9 million contract last year to demonstrate mid-air retrieval of the LOFTID entry vehicle, using an ocean-going ship capable of transporting a helicopter to the recovery zone.

The LOFTID experiment will test a flexible thermal protection system using braided synthetic fibers that are 15 times stronger than steel, according to a NASA fact sheet. Unlike rigid heat shields, the material allows the structure to be folded and packed in a tighter volume that can fit inside the payload envelope of existing rockets.

During the LOFTID demonstration, the heat shield will inflate after the Atlas 5 rocket releases the JPSS 2 spacecraft in orbit. After inflation, the Atlas 5's Centaur upper stage will execute a deorbit burn on a trajectory heading back into the atmosphere, then deploy the LOFTID vehicle for re-entry.

ULA's interest in inflatable heat shield technology stems from the company's plan to recover first stage engines from the next-generation Vulcan rocket for refurbishment and reuse.

The Vulcan rocket is scheduled for its inaugural launch from Cape Canaveral in 2021. Two BE-4 main engines, built by Blue Origin, will power the Vulcan's first stage.

Unlike SpaceX, which lands entire Falcon 9 first stage boosters to be reused, ULA plans to jettison the BE-4 engine pod fr om the base of the Vulcan first stage. The engines will be shielded by an inflatable decelerator, similar to the system to be demonstrated by the LOFTID experiment, then unfurl a steerable parafoil for a helicopter to capture in mid-air.

The BE-4 engines, which burn methane and liquid oxygen, are designed to be reusable. Blue Origin's own New Glenn rocket, also set for a debut in 2021, will also use BE-4 engines on its first stage. Like SpaceX, Blue Origin intends to land the New Glenn's first stage intact for refurbishment and reuse.

ULA will discard the BE-4 engines on the initial flights of the Vulcan rocket. The company plans to begin retrieving the engines around 2024.

Ну у вас везде альтернативное мнение. У Дельты верхняя ступень маленькая потому, что хватает и такой, а дальнейшее увеличение размеров и тяги дает не очень большой прирост ПН, но приличный рост стоимости.

ЦитатаULA Completes Final Design Review for New Vulcan Centaur Rocket
First Flight on Schedule for 2021

Centennial, Colo., May 20, 2019 - United Launch Alliance leaders and engineers completed an important milestone with the conclusion of the system Critical Design Review (CDR) for the company's new Vulcan Centaur rocket. The system-level CDR is the final review of the design for the overall rocket.

"This is a tremendous accomplishment for the ULA team and a significant milestone in the development of a rocket - signaling the completion of the design phase and start of formal qualification," said Tory Bruno, ULA's president and CEO. "Vulcan Centaur is purpose built to meet all of the requirements of our nation's space launch needs and its flight-proven design will transform the future of space launch and advance America's superiority in space."

The system CDR was a week-long detailed review of the entire Vulcan Centaur system with the primary focus to verify all of the elements will work properly together as a system. As part of the certification process with the U.S. Air Force, Air Force representatives are included as part of the design review.

"ULA's Atlas and Delta rockets have served as the backbone for American space launch for decades and our next-generation rocket will advance this rich heritage," said Bruno. "Vulcan Centaur will provide higher performance and greater affordability while continuing to deliver our unmatched reliability and precision."

When the first Vulcan Centaur rocket flies in less than two years, a high percentage of the rocket will have flown before on ULA's Atlas launch vehicle including the fairing, upper stage engines in a dual configuration, avionics, software and solid rocket motors.

"Vulcan Centaur brings together the best of Atlas and Delta technology, and we are flying all of the major components that we can on Atlas V first to reduce the risk for our customers on the first flight," said Bruno.

ULA and its suppliers have invested in and modernized the factory in Decatur, Alabama, bringing in state-of-the art manufacturing technologies. Flight hardware is already being built for the first flight, and the production is on schedule for the initial launch in 2021.

With more than a century of combined heritage, ULA is the world's most experienced and reliable launch service provider. ULA has successfully delivered more than 130 satellites to orbit that provide Earth observation capabilities, enable global communications, unlock the mysteries of our solar system, and support life-saving technology.

ULA Submits Proposal for U.S. Air Force's Launch Services Competition

Centennial, Colo., Aug. 12, 2019 - At the United Launch Alliance (ULA) factory in Decatur, Alabama, production of the first Vulcan Centaur rocket continues, with shipment to the launch site at Cape Canaveral Air Force Station in Florida scheduled for late next year for processing in preparation for its first launch in 2021.

"Atlas and Delta rockets have been the backbone of national security space launch for decades, building on a progressive history of technology development and advancement -- Vulcan Centaur will advance this rich heritage," said Tory Bruno, ULA's president and CEO. "Following the successful launch of our 134th mission just last week on our Atlas rocket, we submitted our purpose-built Vulcan Centaur rocket for the U.S. Air Force's Phase 2 Launch Services competition. It is so exciting to see the first flight vehicle coming together at our factory."

The Department of Defense has established a selection strategy to ensure a smooth transition to a U.S. engine, while introducing competition, driving down costs and safeguarding continued assured access to space by preventing any capability gaps. Nearly one year ago, the Air Force held a competition and awarded three Launch Services Agreements for public-private partnerships to develop launch vehicles. Phase 2 is the next procurement in the Air Force's strategy.

"The nation is facing a contested space environment, and we are unleashing the energy of American ingenuity by developing Vulcan Centaur to meet our nation's need for expanding space missions," said Bruno. "Vulcan Centaur's flight proven design, coupled with innovative technology, is transforming the future of space launch and will advance America's superiority in space."

ULA is the nation's only full-range national security space launch provider and is the most experienced, with more than 130 launches and 100 percent mission success. Additionally, ULA and the heritage companies are the nation's only firms who have ever flown the exquisite Category C heavy-class national security missions, thus providing the country with extreme confidence of continued low-risk mission performance.

"Vulcan Centaur will provide higher performance and greater affordability while continuing to deliver our unmatched reliability and orbital accuracy precision from our treasured cryogenic Centaur upper stage," said Bruno. "ULA is the best partner for national security space launch, and we are the only provider to demonstrate experience flying to all orbits including the most challenging heavy-class missions, providing the bedrock foundation for the lowest risk portfolio of two launch service providers for the U.S. Air Force."

In the factory, the fabrication of the structure for the first Vulcan Centaur rocket continues, and the team recently completed the booster structural test article in Decatur. In Florida, assembly of the new Mobile Launch Platform has begun in preparation for the first launch.

With more than a century of combined heritage, ULA is the world's most experienced and reliable launch service provider. ULA has successfully delivered more than 130 satellites to orbit that provide Earth observation capabilities, enable global communications, unlock the mysteries of our solar system and support life-saving technology.

"Dream Chaser can launch from any conventional rocket so we had great options," said SNC CEO Fatih Ozmen.  "SNC selected ULA because of our strong collaboration on the Dream Chaser program, their proven safety record and on-time performance.  This is bringing America's spaceplane and America's rocket together for best-of-breed innovation and exploration."

Under NASA's Commercial Resupply Services 2 (CRS-2) contract, the Dream Chaser will deliver more than 12,000 pounds of pressurized and unpressurized cargo to the space station and remains attached for up to 75 days as an orbiting laboratory.  Once the mated mission is complete, the Dream Chaser disposes about 7,000 pounds of space station trash and returns large quantities of critical science, accessible within minutes after a gentle runway landing.

SNC's Louisville, Colorado-based Space Systems division is proudly partnering with Centennial, Colorado's ULA, boosting the already strong aerospace economic footprint in the state.

"In this very competitive launch vehicle market, we feel privileged that SNC chose to launch this block of six missions to the ISS with ULA," said Tory Bruno, ULA president and CEO. "This is one of the first contracts for our new Vulcan Centaur rocket, and the first of the six missions will serve as the rocket's second certification flight. We are excited to bring our more than 120 years of combined launch experience with our Atlas and Delta rockets, which build on a progressive history of technology development and advancement, to Vulcan Centaur."

Vulcan Centaur's flight proven design, coupled with innovative technology, is transforming the future of space launch. The new rocket will provide higher performance and greater affordability while continuing to deliver unmatched reliability and precision. Approximately 90 percent of all of Vulcan Centaur's components will be flown first on Atlas V missions, so that its first flight will have reduced risk. Vulcan Centaur is a new class of space launch vehicle with the performance of a heavy launch vehicle in just a single core.

ЦитатаК МКС запустят грузовой корабль Dream Chaser на новейшей ракете Vulcan
23:25 14.08.2019

ВАШИНГТОН, 14 авг - РИА Новости. Запуск шести грузовых многоразовых кораблей Dream Chaser к Международной космической станции (МКС) начиная с 2021 года будет осуществлять новейшая ракета-носитель Vulcan, сообщила в среду компания Sierra Nevada Corporation (SNC).

"SNC выбрала компанию ULA ввиду нашего тесного сотрудничества по программе Dream Chaser, проверенной безопасности и пунктуальности", - сообщил на пресс-конференции глава SNC Фати Озмен (Fatih Ozmen), компания вела прямую трансляцию брифинга.

По контракту с НАСА, создаваемый Sierra Nevada многоразовый крылатый корабль Dream Chaser должен совершить по меньшей мере шесть грузовых миссий на МКС. Корабль должен не только доставлять грузы на орбиту, но также возвращать их с МКС на Землю.

Как в свою очередь рассказал глава компании ULA Торри Бруно, контракт с SNC станет одним из первых для новейшей ракеты Vulcan Centaur и "дебютным коммерческим стартом". "Мы вас не подведем", - сказал Бруно на конференции по случают достижения контракта, стоимость которого осталась неизвестна.

Глава ULA сообщил, что запуск Dream Chaser станет "вторым сертификационным полетом" для ракеты Vulcan. Между тем он не исключил, что в случае изменений в графике введения ракеты в эксплуатацию полеты может совершить ракета-носитель Atlas-5. "План осуществить все шесть миссий на ракете Vulcan, но Atlas-5 также может быть заменой ... Если что-то (непредвиденное) возникнет, мы обеспечим все необходимое, чтобы вы стартовали по мере вашей готовности", - сказал глава ULA. Он сообщил, что Vulcan должна быть готова к полетам в начале 2021 года. Он пояснил, что до этого времени различные части новейшей ракеты будут интегрироваться на ракету Atlas, что позволит испытать Vulcan до начала ее фактических полетов.

Ранее источник в ракетно-космической отрасли РФ сообщал РИА Новости, что первый запуск американского многоразового крылатого грузового корабля Dream Chaser на МКС планируется в сентябре 2021 года, а вывод корабля на орбиту осуществит ракета-носитель Atlas-5 с российским двигателем РД-180 на первой ступени.

ULA создает Vulcan на смену Atlas-5, первая ступень новейшей РН будет обеспечена жидкостным двигателем BE-4, который разрабатывает компания Blue Origin.

Как заявили на пресс-конференции представители компании Sierra Nevada, компания продолжает работу над созданием пилотируемой версии Dream Chaser и не исключает, что корабль будет совершать полеты в том числе на орбиту Луны.

ЦитатаAstrobotic Selects United Launch Alliance Vulcan Centaur Rocket to Launch its First Mission to the Moon

Pittsburgh, Penn., and Centennial, Colo., Aug. 19, 2019 - Astrobotic announced today that it selected United Launch Alliance's (ULA) Vulcan Centaur rocket in a competitive commercial procurement to launch its Peregrine lunar lander to the moon in 2021.

"We are so excited to sign with ULA and fly Peregrine on Vulcan Centaur. This contract with ULA was the result of a highly competitive commercial process, and we are grateful to everyone involved in helping us make low-cost lunar transportation possible.  When we launch the first lunar lander from American soil since Apollo, onboard the first Vulcan Centaur rocket, it will be a historic day for the country and commercial enterprise," said Astrobotic CEO, John Thornton.

Astrobotic, the world leader in commercial delivery to the moon, was selected by NASA's Commercial Lunar Payload Services (CLPS) program to deliver up to 14 NASA payloads to the Moon on its Peregrine lunar lander in 2021. With this $79.5 million CLPS award, Astrobotic has now signed 16 customers for lunar delivery on its first mission.

"Our rockets have carried exploration missions to the moon, the sun and every planet in the solar system so it is only fitting that Vulcan Centaur's inaugural flight will lead the return of Americans to the lunar surface," said Tory Bruno, ULA's president and CEO. "We could not be more excited to fly this mission for Astrobotic."

Astrobotic's Peregrine lunar lander will launch on a Vulcan Centaur rocket from Space Launch Complex-41 at Cape Canaveral Air Force Station in Florida. The launch of this mission will serve as the first of two certification flights required for ULA's U.S. Air Force certification process.  

"This partnership represents a true 'whole-of-government' approach to how our nation is leading the world in space: NASA contracted with a commercial company to land on the moon, who then went on to contract with a commercial company for a rocket built to serve the national security space market," said Bruno. "This highlights the power of our American system of partnership between government and industry to solve the toughest problems and the greatest of our human aspirations."

ЦитатаVulcan Centaur pathfinder validates launch site processes
Feb 20, 2020, 07:51 AM

United Launch Alliance engineers and technicians recently completed a successful pathfinder exercise to assess procedures and operations in Cape Canaveral, Florida, in preparation for the first Vulcan Centaur launch in 2021.

(https://www.ulalaunch.com/images/default-source/default-album/vulc_pathfiner-4.jpeg?sfvrsn=30001dcb_0)

The pathfinder used a mass simulator built specifically to mimic the mass of Vulcan Centaur's core stage, as well as an outer diameter of 17.7 feet. The simulator was transported fr om the Port Canaveral wharf, wh ere the R/S RocketShip will deliver Vulcan Centaur rockets, to ULA facilities for processing.

The highlight of the rehearsal was hoisting the simulator at the Vertical Integration Facility (VIF) to verify the tools and techniques that will be employed next year for the next-generation rocket's maiden launch campaign.
   
This valuable pathfinder exercise proved that all of the new ground support equipment and modifications to the VIF can support both the Atlas V and much larger Vulcan Centaur. The two distinctly different rocket families will share the assembly building and Space Launch Complex-41 (SLC-41) for the next several years as Atlas operations wind down and Vulcan Centaur launches ramp up. The modifications made to the VIF created a flexible facility that can be quickly reconfigured to support either Vulcan Centaur or Atlas V.
   
SLC-41 will be the first launch pad in the world to serve two entirely separate rocket families at the same time. The differences between Atlas and Vulcan Centaur include their size, the types of fuel used and the main engines that power them skyward. The Atlas V first stage is 12.5 feet diameter, uses a highly refined kerosene, called RP-1, and an RD-180 engine. Vulcan Centaur is 17.7 feet wide, will be powered by liquefied natural gas propellant, and use two BE-4 main engines.
   
Each rocket family will have its own dedicated Mobile Launch Platform (MLP). Vulcan Centaur's MLP is being outfitted with electrical and fluid lines at the nearby Spaceflight Processing Operations Center (SPOC), which is connected to the VIF and SLC-41 by rail.
   
The first Vulcan Centaur rocket that will perform its inaugural flight is already under construction at ULA's manufacturing factory in Decatur, Alabama.

Они уточнили, что двигатель доставлен на предприятие ULA в городе Декейтер (штат Алабама). В консорциуме отметили, что запуск Vulcan Centaur, как ожидается, состоится в 2021 году. Разгонный блок данного носителя должен быть оснащен двумя двигателями BE-4. Они были разработаны Blue Origin в качестве альтернативы российским РД-180, которые применяются в ракетах Atlas. Носители Vulcan Centaur, как ожидается, придут на смену Atlas.
Представители Blue Origin сообщили журналистам портала Space News (https://spacenews.com/blue-origin-delivers-the-first-be-4-engine-to-united-launch-alliance/), что второй BE-4 планируется доставить ULA до конца текущего месяца. Они отметили, что двигатели на данном этапе предназначаются для проведения специалистами тестов. В ULA не уточнили, когда компания получит от Blue Origin двигатели BE-4, которые предназначены непосредственно для полета.
В ULA и Blue Origin пока не ответили на запрос ТАСС с просьбой представить подробности относительно того, как будут проходить испытания и дальнейшие поставки двигателей.

Соглашение между Москвой и Вашингтоном, которое предусматривало поставки в США 101 двигателя РД-180 и оценивалось примерно в миллиард долларов, было заключено в 1997 году. В 2014 году Конгресс США из-за обострения отношений с РФ ввел запрет на использование РД-180, но в 2015 году отменил его, когда стало ясно, что свои двигатели в течение ближайших лет в США созданы не будут. Позднее законодатели одобрили поправку к проекту оборонного бюджета, предусматривающую приобретение еще 18 таких двигателей в период до 2022 года.

1. ВЕ-4 все таки еще не доведен до ума ( 243 тс земной тяги + проектные переходные режимы) . Но для Vulcan Centaur можно урезать запросы, есть ТТ бустеры. Но вот для NG все таки желательно максимально приблизиться к проектным значениям, с учетом и потребного многократного включения. :(
2.Выбор максимального давления в КС 132 кгс/см.2 сделан по рекомендациям Старого, габариты внушають. В сравнении с Раптором не впечатляет. Хотя у Раптора судя по косвенным признаком имеются подводные камни, о  которых Маск скромно умалчивает. ;D

Если он продемонстрирует все, что им требуется, и быстро, не слишком утрудившись, то почему нет? Они просто скажут "Вот по той же ТД, по какой сделали этот, сделаем и остальные". Тогда проблемы белой вороны просто не будет )

15:37 ИЮЛЬ 6, 2020
Военный обозреватель газеты «Военно-промышленный курьер» Олег Фаличев также объяснил отказ США от российских двигателей РД-180.
...
Российский двигатель РД-180 планируется заменить на агрегат BE-4, разработанный компанией United Launch Alliance (ULA). Фаличев отметил, что иностранная установка сконструирована более экономично, чем отечественная.

«Есть разные показатели по тяге, в тяге они немножко проигрывают нам, этот двигатель, но в то же время тяга в космосе такая же. По общим показателям этот двигатель ничем не уступает РД-180, позволяет выводить грузы и людей на орбиты. Если наш двигатель, РД-180, стоит 25 миллионов долларов, то двигатель у американцев, он состоит из нескольких маленьких двигателей, но общая стоимость первой ступени двигательной равна 14 миллионам долларов, это в два раза дешевле, чем у нас».

Цитата: undefinedNew fairing for Atlas V is stepping stone to Vulcan Centaur

In another example of driving down cost while delivering the launch services our customers expect, ULA is transitioning to a new kind of payload fairing that is more affordable and easier to build. ULA technicians took delivery of the first one recently at Cape Canaveral, Florida.

The Out-of-Autoclave (OoA) fairings will be used on upcoming Atlas V launches to accumulate flight experience before use on Vulcan Centaur, reducing risk for our next-generation rocket. In fact, a significant portion of systems will have flown on Atlas and Delta rockets before its inaugural launch next year.

The first OoA fairing was transported to the launch site by the RocketShip vessel from the RUAG Space USA manufacturing in Decatur, Alabama. It was offloaded from the ship at the Cape Canaveral wharf to begin pre-launch preparations.

RUAG Space formed a strategic partnership with ULA and established production capabilities inside our Decatur plant to make fairings and other composite structures in the U.S. The OoA fairing recently delivered is American-made by RUAG Space USA.

RUAG Space previously manufactured the Atlas V 5.4-meter-diameter payload fairings in Emmen, Switzerland. Those have flown nearly 30 times, all successfully.

The Out-of-Autoclave manufacturing method is an alternative process to cure carbon fiber composites using only an oven. It avoids a high-pressure autoclave that is expensive and restricts the size of pieces that can fit inside.

"Utilizing the OoA manufacturing approach allows for a more efficient production process, lower cost and lower system mass while maintaining the same level of reliability and quality as the heritage in-autoclave composites," said Amanda Bacchetti, ULA's payload accommodations leader for Vulcan Centaur.

The OoA oven allows the payload fairings to be produced in two halves instead of 18 or more smaller sections from the in-autoclave process. That means less opportunities for defects, fewer fasteners and doublers to hold the pieces together and a quicker manufacturing time.

"All that simplification leads to lower costs, higher reliability and less weight, which is an important point in the launch industry," said Robbie Harris, program office manager at RUAG Space USA.

The OoA 5.4-meter fairings for Atlas will continue to be made in different lengths for encapsulating the satellites during ascent through the atmosphere and retain the heritage design that features lower sections, called the base module, that surround the Centaur to share the loads from heavy payloads.

For Vulcan Centaur, however, the fairing will attach to the top of Centaur V and not enclose the upper stage. That will make the production even simpler and more affordable.

"The Vulcan Centaur fairing is a further evolution of the payload fairing design. It will be the same in terms of the Out-of-Autoclave material technology, but RUAG Space and ULA have worked together to eliminate some of the manufacturing steps that need to be taken after the cure," Harris explained.

RUAG Space will also supply Payload Attach Fittings (PAF), Interstage Adapters (ISA), and other composite parts for the Vulcan Centaur rocket using OoA technology.

ЦитатаNorthrop Grumman Successfully Completes First Qualification Test of New Rocket Motor for United Launch Alliance

New graphite epoxy motors will help launch ULA's Vulcan Centaur rocket beginning in 2021

 August 13, 2020

PROMONTORY, Utah - Aug. 13, 2020 - Northrop Grumman Corporation (NYSE: NOC) conducted its first ground test of an extended length 63-inch-diameter Graphite Epoxy Motor (GEM 63XL) today in Promontory, Utah. This variation of the company's GEM 63 strap-on booster was developed in partnership with United Launch Alliance (ULA) to provide additional lift capability to the Vulcan Centaur vehicle.


Northrop Grumman conducted the first test of its GEM 63XL rocket motor to serve the United Launch Alliance Vulcan Centaur on August 13 at its Promontory, Utah, facility.

"Our new GEM 63XL motors leverage its flight-proven heritage while utilizing state-of-the-art manufacturing technology to enhance launch vehicle heavy-lift capabilities," said Charlie Precourt, vice president, propulsion systems, Northrop Grumman. "The GEM 63XL increases thrust and performance by 15-20 percent compared to a standard GEM 63."

During today's static test, the motor fired for approximately 90 seconds, producing nearly 449,000 pounds of thrust to qualify the motor's internal insulation, propellant grain, ballistics and nozzle in a cold-conditioned environment. This test demonstrated materials and technologies similar to the GEM 63 rocket motor that qualified for flight in October 2019.

Northrop Grumman has supplied rocket propulsion to ULA and its heritage companies for a variety of launch vehicles since 1964. The GEM family of strap-on motors was developed starting in the early 1980s with the GEM 40 to support the Delta II launch vehicle. The company then followed with the GEM 46 for the Delta II Heavy, and the GEM 60, which flew 86 motors over 26 Delta IV launches before retiring in 2019 with 100 percent success. The first flight of the GEM 63 motors will be on a ULA Atlas V launch vehicle planned for fourth quarter 2020, and GEM 63XL motors will support the Vulcan rocket in 2021.

Чарльз Лурио пишет в недавнем отчёте:

It was a shock to hear of the sudden death of Bernard Kutter, Chief Scientist and Manager of Advanced Programs at the United Launch Alliance, on August 12.  He was 55.

While he worked within the framework of a "traditional" space company, his personal goals were within the vision of New Space.  He had been head of advanced programs for many years and I'd met him at several conferences. He was described as the "father" of the ULA's Vulcan rocket, which incorporates several unconventional features...

I found in my files copies of correspondence between Kutter and myself in 2010 on a draft write-up for this Report on space propellant depots (Vol. 5, No. 6, April 30, 2010).  It was evidently largely based on a panel he was on at the Space Access Conference of that spring. That was the era - which has left 'debris' even to this late date - when it was effectively forbidden by NASA that their people visibly admit that depots were desirable or feasible, at least without prohibitively costly research.  Of course, this was to prevent angering the SLS pork-mafia on the Hill.  In my 2010 story I recounted,

"'Hogwash', said Bernard Kutter during this panel; we don't need new technology for space propellant depots, just some demonstrations...[and] the required tests wouldn't be particularly expensive." Despite the opposition, finally, at the end of 2017, George Sowers, who had had similar titles as Kutter until leaving ULA in March 2017, could tweet, "Bernard Kutter of [ULA]: problems of cryogenic propellant storage and transfer now SOLVED. Enables the cislunar economy..."

ЦитатаULA: перенос сроков запуска корабля Dream Chaser не помешает сертификации ракеты Vulcan
Для того чтобы сертифицировать свою ракету Вулкан для выполнения пусков в интересах Пентагона ULA необходимо провести два успешных пуска. При этом во время намеченного на 2021 год первого пуска в космос должен быть выведен лунный посадочный модуль Astrobotic, а во время второго - грузовой корабль  Dream Chaser компании Sierra Nevada Corporation (SNC). В этой связи сделанное компанией Sierra Nevada заявление о переносе запуска на 2022 год породил соответствующие сомнения относительно планов ULA по сертификации своей ракеты. В частности многие отмечают, что корабль может быть не готов и к 2022 году, а следовательно компании придется искать альтернативу или выводить массо-габаритный макет. С другой стороны это не означает, что компания не сможет оказывать услуги по запуску военных аппаратов поскольку контрактом предусмотрена альтернатива в виде ракет Atlas-5, пишет Ecoruspace.

ЦитатаVulcan Centaur: Rehearsal helps shape new rocket's countdown formula
Dec 2, 2020, 07:44 AM

ULA launch team members conducted a simulated countdown Dec. 1 to test their work in crafting the procedures and timelines that will be used next year to launch the first Vulcan Centaur rocket.

Dillon Rice, a veteran Atlas V and Delta IV launch conductor, orchestrated the simulation at Cape Canaveral with the assistance of ULA Chief Launch Conductor Doug Lebo.

The event also provided training for the control room operators staffing the liquid oxygen, pneumatics and propulsion consoles. A half-dozen engineers participated in the test from those stations.

The rehearsal enabled the team to evaluate the ongoing development of plans and procedures for the portion of the countdown when liquid oxygen is loaded into the Vulcan Centaur rocket's first stage. The demonstration offered a realistic practice session to check time requirements and the cadence of activities.

The successful simulation is just one step in shaping the countdown formula needed to ready a Vulcan Centaur rocket for launch.

The test began from the T-minus 3 hour point in the countdown with a "go" from the launch conductor to the first stage liquid oxygen console operator, known as LOX1, to initiate a simulated chilldown. That is the precursor step to thermally condition the transfer line from pad's giant liquid oxygen storage sphere to the rocket.

Once chilldown parameters were achieved, the launch team activated and oversaw the automated computer files that control filling the rocket's main stage with oxidizer.

The team mimicked achieving a full tank, then set off to perform standard countdown steps including valve cycling tests and charging the POGO system that dampens oscillations in liquid-fueled rockets.

After the simulation participants voiced their satisfaction that the countdown objectives had been met, the rehearsal then switched to its next phase to demonstrate the plans for draining the liquid oxygen out of the rocket.

Detanking and safing procedures also went smoothly in the test, giving the ULA Launch Operations team a success in its preparations for the inaugural Vulcan Centaur mission.

Future simulations will evaluate other elements of the launch countdown development, leading to a real-life fueling test and a Flight Readiness Firing using a pathfinder Vulcan Centaur rocket on the pad.

Потому что мало испытаны движки. У Ангары они с проверенными технологиям от РД-170. Старшип при куче прожигов и полетов не стабилен. А тут даже никаких полетов не было.

Пусть опережает. Они не сопоставимы. Мелочь против супертяжа. Фалькон-9 уже опередила это поделие по многоразовости, по цене, по надежности.

Что за детский сад.

Многоразовость не является самоцелью.
Это лишь способ (не всегда оправданный ) повлиять на себестоимость.
В области РН целесообразность "многоразовости" не подтверждена экономическими выкладками.
Там где есть открытые данные по финансовым раскладам с малой вероятностью фальсификации
потуги на многоразовость приводили только к удорожанию услуг по запуску космических ПН.
Яркий пример Шаттл.
Ну а пиарная похвальба "многоразовостью" Маска  (причем только первой ступени, недалеко ушедшей по скорости полета от СЕРИЙНыХ самолетов)
совершенно пуста без ответственной финансовой отчетности.
Более низкая цена Фалконов связана с другими факторами - в частности с дешевизной гениально сконструированных простых надежных и легких Мерлинов.


Маск гений пиара - он нащупал эрогенную зону тупого хомячья(восприятие многоразовости как самоцели вследствие ограниченного житейского опыта)
и давит на эту эрогенную зону со всей силы, надеясь сконвертировать внимание многосотмиллионного стада баранов в финансовые инвестиции.

Ок. Предлагаю исходить из того, что «ответственную финотчетность» SpaceX ни вам, ни даже Дмитрий Олеговичу не предоставит.
Кроме того, зачем вам финотчетность об экономической эффективности Falcon 9?
Роскосмос же не Ф9 будет запускать. И возвращать ступень будет не на Мыс Канаверал.
И расходы у него совершенно другие будут, и методички по послеполетному обслуживанию.

А у Арианспейса - своя ракета, и свои методики, и зарплаты отличаются, а значит и бизнес-кейс по многоразовости будет тоже свой.

У нас тут форум малолеток с ДЦП, чтобы шестой год мусолить идиотскую отмазку, что СпейсХ, гады такие, не предоставляют нам «ответственную финотчетность», а значит и начинать делать ничего нельзя?

Инвесторы отлично понимают, что снижение стоимости доступа может быть монетизировано, в том числе через заказы на межпланетные полёты, хотя бы через заказы от государственных агентств. Резкое снижение стоимости доступа на орбиту позволит разными способами зарабатывать деньги, и инвесторы это отлично понимают. А Маск понимает, что наличие такой инфраструктуры позволяет запустить его проект создания Марсианской Колонии.
   
Так что тут взаимовыгодные отношения, Маску не надо обманывать инвесторов. Он же не собирается использовать эту инфраструктуру исключительно для создания Марсианской Колонии.

Снижение стоимости доступа действительно может быть монетизировано (да и не «может быть», а так и происходит). 
Но не нужно думать, что конечной целью для инвесторов является Марс, а все остальное- лишь этапы. 
СпХ, как и упомянутый вами Blue Origin, вместе со многими другими ракетными компаниями (включая даже Роскосмос) переходят на многоразовость и метан не из-за того, что эти технологии откроют им путь на Марс, а из-за очевидной выгоды здесь и сейчас. 

Маск, как вы наверняка не раз слышали, хочет создать базу на Марсе для того, чтобы у человечества появился «запасной аэродром». Это хорошая и благородная цель, которую я всячески поддерживаю, но не нужно думать что инвесторы вкладывают деньги находящиеся у них в управлении в компанию SpaceX потому, что целью Илона Маска является Марс.

Цель можно сформулировать так: " Создание ракетной транспортной системы, обеспечивающей как увеличение веса ПН, так и доступной dV на 5-7км/сек для всего диапазона ПН по сравнению со всеми известными РН на сегодняшний день".
Как видите, нет ни слова о многоразовости, поскольку она средство, но никак не цель. Возможны другие средства достижения этой цели - принципиально другие двигатели например. Тогда сидим ровно и ждем их.  Для Маска эта цель видимо актуальна, и достигать ее он собирается через многоразовость танкеров и орбитальные заправки сверхтяжелых РБ  (собственно Старшипа).

Освоение Солнечной Системы (Марсианская Колония это только начало) и есть тот самый killer app. Да, Маск создает систему, потенциал которой на несколько порядков больше существующего рынка. Но посмотрите на все бизнесы Маска, он везде создаёт новые рынки.

Вы слишком много смотрите наш телевизор. Например, регулярно проходят конференции о орбитальных солнечных электростанциях. На самом деле есть множество технологий орбитального производства, две уже опробованы - биопечать органов и производство волокна ZBLAN:
ЦитатаВ июле 2018 года, на МКС, наконец, был доставлен прототип устройства для изготовления фторидного оптоволокна. В настоящее время идут тесты прибора. Третий тест ожидается в ноябре-декабре этого года, после чего образцы продукции будут отправлены на Землю. Если опыты окажутся успешными - на орбите будет развернуто оборудование для промышленного производства.

Есть серьёзное продвижение в термоядерных технологиях, лет через десять термоядерный двигатель будут обсуждать, как с 2016 года обсуждали Старшип во всех итерациях. А это означает, что через тридцать лет на Марс можно будет летать за десять дней.

Чтоб пробовать надо иметь эту возможность. У того у кого она есть другие интересы. Офис на месте руин хруников, да пилеж на фантазиях про ядерные буксиры. )))

Чем, интересно, вдохновляет инженеров Рогозин?
Но главное - работает. А верит Маск в то, что говорит или нет - судить не могу, ему в голову ж не залезешь.

За Рогозиным не слежу :(

Цитата: Дмитрий В. от 16.02.2021 18:47:23Любая разумная деятельность предполагает формулирование целей и задач для их выполнения. Цели, как мы знаем, должны быть амбициозными, актуальными, достижимыми, измеримыми и ограниченными во времени. Пока же, кроме неразумных хотелок типа "многоразовость - это круто, моднои современно", у сторонников повторного использования, увы, аргументов нет.
Вообще "многоразовость" это средство, а не цель. Цель Маска - сделать человечество мультипланетным, и сделать это при при жизни Маска, так что это цель "амбициозная, актуальная, достижимая, измеримая и ограниченная во времени" - всё, как вы хотите.
   
И, да, в рамках этой цели поставлена задача - начать создание Марсианской Колонии. А для этой задачи есть средство - многоразовость. При этом это средство позволяет ставить другие задачи и намечать свои цели.

Пока же, никаких ультимативных аргументов против многоразовости у её противников нет.

Учитывая, как он говорит "нужна новая масштабная и амбициозная цель, которая объединит всё промышленность" (с) "как-то так, почти дословно", то либо её не было, либо старая протухла.

В порядке бреда - обезьянничание за Артемидой, либо база на Каллисто.

В любом случае, свою сверхтяжёлую РН он видит как средство запуска ПН на орбиту Земли - и цель эта первоочерёдна. Был твит то ли самого Маска, то ли Шотвел о том, что первые десятки-сотни пусков сверхтяжа будут коммерческими.

Цитата: Георгий от 16.02.2021 15:45:58вообще непонятен смысл этих заявлений. бред же полнейший. не проще ли Антарктиду и Тибет колонизировать. даже с помощью Starship хоть какая-то прибыль  просматривается.
Алло, гараж! Антарктида и Тибет ближе и дешевле, но они на Земле. Марс дальше, но это другая планета, потенциал совершенно другой.
Яблоки оттуда возить?
Или гелий-3?
Я вам намекаю, что нет там таких природных ресурсов, ради которых стоит переться в такую даль.
Если речь о рефугиуме от возможной ядерной войны, то проще его сделать в Антарктиде и Тибете или в подземных пещерах жить (норникель, вон, 750 км выкопал, или мосметро), со светом от ядерных реакторов.
Вы очень хорошо разбираетесь в колбасных обрезках современной экономике? Я что-то сомневаюсь. Для современной глобальной экономики планета уже тесновата, освоение Солнечной Системы даёт ей рынок сбыта на несколько сотен лет. Как правило космические ресурсы нужны не для Земли, а для потребления там же, в космосе. Это называется экспансия.

Ну почему? Есть.
   
Космическая индустрия возникла как мобилизационная деятельность, и апологеты одноразовости считаю, что именно такой она и должна остаться. А это означает редкие полёты, и отсутствие освоения дальнего космоса. То есть околоземное пространство ещё с грехом пополам осваивается, а перспектив освоения дальнего космоса большинство государств не видит. Обратите внимание, что многоразовость продвигают рыночные компании. И ещё. Китай и Арабские Эмираты официально поставили создание национальной Марсианской Колонии целью своих космических агентств, причём арабы хотят построить город на Марсе. Денег у них достаточно.

10 тыс сек - вполне нормальная наработка. РД-180 наработал за четверть века 37 000 сек, включая ОТИ серийных ЖРД.
