WASHINGTON — Sparks, Nev.-based Sierra Nevada Corp. was the big winner in NASA's Commercial Crew Development (CCDev) competition, receiving $20 million of the $50 million in economic stimulus money meant to seed development of commercial crew transportation services.

NASA Administrator Charles Bolden announced the names of the five selected companies during a Feb. 1 teleconference to discuss the U.S. space agency's plan to cancel the Moon-bound Constellation program and rely on commercial operators to fly astronauts to an international space station the United States now intends to support through at least 2020.

In a press release issued after U.S. markets had closed, NASA announced that Chicago-based Boeing Co. will receive $18 million; Denver-based United Launch Alliance will receive $6.7 million; Kent, Washington-based Blue Origin will get $3.7 million; and Tucson, Ariz.-based Paragon Space Development Corp. will get $1.4 million.

"These selections represent a critical step to enable future commercial human spaceflight," Doug Cooke, NASA associate administrator for exploration systems said in a written statement. "These impressive proposals will advance NASA significantly along the path to using commercial services to ferry astronauts to and from low Earth orbit, and we look forward to working with the selected teams."

Each of the selected companies signed Space Act Agreements with NASA  that will fund performance-based milestones that begin in February, according to the release.

NASA did not release details about the selected projects.

A Sierra Nevada executive,however, told Space News late last year that the Sparks, Nevada-based company's plan involves a runway-landing, lifting-body vehicle called Dream Chaser that the company has been working on for several years. The six-passenger vehicle is based on NASA's HL-20 concept from the early 1990s

A Paragon executive said last November that the company proposed a yearlong effort to build and demonstrate an air revitalization system that could be incorporated into any contemplated commercial space capsule, including Space Exploration Technologies' Dragon capsule or a crewed variant of the Cygnus vehicle proposed by Dulles, Va.-based Orbital Sciences Corp.

The Commercial Crew and Cargo Program Office at NASA's Johnson Space Center in Houston is managing this effort.

ЦитироватьDream Chaser is an RLV under development by SpaceDev to serve suborbital and orbital applications.
The design of this vehicle is based on the NASA HL-20 spaceplane concept from the early 1990s,
which was itself inspired by the successfully launched Soviet BOR-4 spaceplane from the early 1980s.
Dream Chaser has been expanded from the original HL-20 by 10 percent to an overall length of 9.6
meters (31.5 feet) and wingspan of 8 meters (26.2 feet). The Dream Chaser is designed to
transport 6-9 passengers, compared to the original HL-20's capacity of 6-10. On orbital flights, the
vehicle will launch on top of existing launch vehicles. The vehicle will glide back to a runway landing.

With NASA's October 2008 certification that SpaceDev had successfully performed its Internal Space Vehicle
Propulsion Module Preliminary Design Review (PDR), SpaceDev has completed three technical milestones
to date under the unfunded SAA. SpaceDev has also signed a memorandum of understanding (MoU)
with United Launch Alliance (ULA) in April 2007 to study the use of the Atlas V to launch the Dream Chaser
on orbital missions, and is collaborating with ATK to study the integration of the Dream Chaser on an
Ares I-derived launch vehicle.

Dec 17, 2010
 
By Frank Morring, Jr.

Virgin Galactic plans to market orbital flights for space tourists and scientists on two spaceplanes proposed under NASA's Commercial Crew Development (CCDev) effort, in the hope it can expand its business beyond the suborbital flights it is planning on its SpaceShipTwo vehicle.

The company has signed on as a teammate with both Orbital Sciences Corp. and Sierra Nevada Corp. in the second round of competition for NASA seed money to develop commercial human spacecraft that can deliver crews to the International Space Station. The space agency is offering $200 million in this round.

"We are now very close to making the dream of suborbital space a reality for thousands of people at a cost and level of safety unimaginable even in the recent past," says Richard Branson, founder of Virgin Galactic. "We know that many of those same people, including myself, would also love to take an orbital space trip in the future, so we are putting our weight behind new technologies that could deliver that safely whilst driving down the enormous current costs of manned orbital flight by millions of dollars."

Both of Virgin's teammates are basing their CCDev entries on winged spaceplanes that will take off vertically atop an expendable launch vehicle and return to a gliding runway landing.

Sierra Nevada, which won $20 million in the first CCDev competition to begin work on its Dream Chaser vehicle, will use the same hybrid-rocket technology that powers SpaceShipTwo, and has already built the tooling for its composite airframe.

"We are thrilled to have Virgin Galactic as part of our effort to make commercial orbital transportation a reality," says Mark Sirangelo, corporate vice president and head of Sierra Nevada Space Systems. "The knowledge gained in the development and promotion of the history-making SpaceShipTwo suborbital system will add considerably to our program."

The Dream Chaser will go into orbit on the nose of a rocket, then land gently on airport runways.

Once the space-shuttle program ends this year, the only way to get people into orbit and to the International Space Station will be to buy seats on Russia's three-person Soyuz capsules. So NASA, through its Commercial Crew Development program, has given $50 million in grants to companies developing new spacecraft capable of carrying people and supplies into orbit and to the space station.

The recipient of the biggest chunk of this money was the Sierra Nevada Corporation, which received $20 million to develop the Dream Chaser. This spacecraft, the size of a business jet, will take cargo and up to eight people into low Earth orbit, where the space station is located, and then return and land on commercial airport runways.

The company reached all its development milestones for the Dream Chaser last year and is now finishing a battery of tests on the craft's carbon-composite frame. The shell of the spacecraft must be able to endure heavy loads and intense vibrations. So the Dream Chaser frame has been mounted on an earthquake simulator in a lab at the University of Colorado in Boulder. So far, the design has performed as expected, says Mark Sirangelo, head of Sierra Nevada's Space Systems division. At facilities in San Diego, the company has been testing the craft's hybrid rocket motors. In the coming months, the company will put the two together to complete a full prototype, carry it into the air, and drop it to see how it flies.

Other orbital spacecraft under development by companies including SpaceX and Boeing are capsules that will use parachutes to descend on land or in the sea. The Dream Chaser has a lifting body design; it looks something like an airplane without the large wings on the side. Another private company, Orbital Sciences, is also working on a space-shuttle-like lifting body craft. The Dream Chaser's shape, in combination with extensible wheels and motors, will enable it to make a controlled landing on a runway. Sirangelo says that the craft will therefore be able to land on the ground in more places than other vehicles can, and that the gravitational forces to which it will expose passengers—and sensitive cargo and scientific instruments—will be less intense.

ASTRONAUT TRANSIT NASA provided $20 million for the development of the Dream Chaser, illustrated here docking at the International Space Station.

BOULDER, Colo. — Sitting in a testing facility at the University of Colorado, the inner shell of the Dream Chaser space plane looks like the
fuselage of an old DC-3.

The test structure has been pushed and pulled to see how it holds up to the stresses and strains of spaceflight. With an additional infusion of money from NASA, the company that makes the Dream Chaser, Sierra Nevada Space Systems, hopes to complete the rest of the structure and eventually take astronauts to orbit.

"Our view is if we could stop buying from the Russians, if we could make life cheaper for NASA, and if we could build a few vehicles that do other things in low-Earth orbit that are valuable, isn't that, at the end of the day, a good thing?" said Mark N. Sirangelo, the company's chairman.

The Dream Chaser is one of several new spacecraft that companies are hoping to launch into space with help from the government. Last year, the Obama administration pushed through an ambitious transformation for NASA: canceling the Ares I rocket, which was to be the successor to the current generation of space shuttles, and turning to the commercial sector for astronaut transportation.

So far, most of the attention in this new commercial space race has focused on Boeing, which has five decades of experience building spacecraft, and Space Exploration Technologies Corporation — SpaceX, for short — a brash upstart that gained credibility last year with two launchings of its Falcon 9 rocket.

SpaceX, led by Elon Musk, a founder of PayPal and chief executive of Tesla Motors, already has a NASA contract for delivering cargo to the space station, and says that it can easily add up to seven seats to its Dragon cargo capsule to make it suitable for passengers. Boeing is also designing a capsule, capable of carrying six passengers, under the corporate-sounding designation of CST-100.

But Boeing and SpaceX are not the only competitors seeking to provide space taxi services, a program that NASA calls commercial crew. Last year, in the first-round financing provided for preliminary development, Sierra Nevada Space Systems won the largest award: $20 million out of a total of $50 million.

In December, another space company, Orbital Sciences Corporation, announced it had submitted a similar bid for a space plane it wants financed during the second round. NASA is to announce the winners by the end of March, and they will divide $200 million.

About half of NASA's $19 billion budget goes toward human spaceflight — the space shuttles, the International Space Station — and $200 million this year is just a small slice.

"If this is indeed the path to do this work, it's probably not what they should be putting into it," said Mr. Sirangelo, who is also chairman emeritus of the Commercial Spaceflight Federation, a trade group. "But on the other hand, it's a lot more than we had before. And it's an acknowledgment there's momentum in the industry and what we're trying to accomplish. So that's good."

After the second round, NASA would like narrow its choices down to two, maybe three, systems to finance.

"We think this is in effect a one-year race to see who gets the furthest," Mr. Sirangelo said, "and at the end of that, presumably the next two years of the authorization bill gets funded, and then you compete for that pot of money."

The blueprint for NASA, passed by Congress last year and signed into law by President Obama, calls for spending on commercial crew to rise to $500 million each year in 2012 and 2013.

Senator Bill Nelson, the Florida Democrat who was one of the primary architects of the blueprint, as the authorization act was called, has said the intent was to provide $6 billion over six years.

But what Congress puts into the budget could be far less.

"They're not getting $6 billion over six years for commercial crew," said a Senate aide who was not authorized to speak for attribution. "That's never going to happen."

The aide estimated commercial crew might receive half that much.

In addition, Congress has not passed the final 2011 budget, and Mr. Obama wants to freeze spending at many federal agencies. Whether the freeze includes NASA will not be known until the president's 2012 budget request is released in two weeks.

While Sierra Nevada has the lowest profile of the companies seeking commercial crew business, it is not new. The parent company, the Sierra Nevada Corporation, is a privately held defense electronics firm founded in 1963, and a few years ago, it bought several space companies and rolled them into the space systems subsidiary.

The space systems subsidiary, located outside Denver, is the largest manufacturer in the United States of small satellites, Mr. Sirangelo said. The satellites, used for communications and other purposes, cannot do everything that large ones can do, but what they can do, they do more cheaply and more efficiently.

The Dream Chaser embodies the same philosophy. "There are some tasks that can be done by smaller, cheaper vehicles that used to be done by very expensive vehicles," Mr. Sirangelo said.

Mr. Sirangelo said the company had invested its own money into the Dream Chaser — indeed, more than the $20 million that NASA has provided. Over the past year, the company has done a test-firing of the engines it plans to use on the Dream Chaser, and it dropped a scale model of the spacecraft from a helicopter to verify the aerodynamics.

But it is a jump from making spacecraft components and small satellites to building a crew-carrying space plane, and where Sierra Nevada lacks in skills and experience, it has brought in other companies and institutions. Its Dream Chaser partners include Draper Laboratory, which has been designing spacecraft guidance systems since Apollo; NASA's Langley Research Center, which did much of the development that the Dream Chaser is based on; Boeing, which has also worked on space planes; and United Launch Alliance, a joint venture of Boeing and Lockheed Martin that builds the Atlas V rocket that the Dream Chaser would ride atop.

Virgin Galactic, the spacecraft division of Sir Richard Branson's Virgin empire, signed on as a strategic partner in December. Among the possible roles that Virgin could play is selling seats on the Dream Chaser. (Virgin signed a similar agreement with Orbital.)

The design of the Dream Chaser also has a long lineage, inspired by a Soviet spacecraft. In 1982, an Australian reconnaissance airplane photographed a Russian trawler pulling something with stubby wings out of the Indian Ocean. It turned out to be a test flight of a space plane called the Bor-4, and the craft captured enough curiosity that engineers at NASA Langley copied it.

NASA called its version the HL-20, and for a while in 1991, it looked to be the low-cost choice for taking astronauts to and from the space station. Then the NASA administrator who liked it, Vice Adm. Richard Truly of the Navy, left, and the man who replaced him, Daniel S. Goldin, thought it was not cheap enough and ended the work.

The Dream Chaser design keeps the exact outer shape from the HL-20 — a decision that allows Sierra Nevada to take advantage of years of wind tunnel tests that Langley had performed — while modifying the design within. The biggest change is the addition of two engines, which reduces the number of passengers to seven from 10, but adds maneuverability. To finish developing the Dream Chaser would require less than $1 billion, Mr. Sirangelo said, and it could be ready to fly an orbital test flight in three years.

He imagines that one flight could combine a number of tasks — taking astronauts to the space station and then stopping on the return trip to repair or refuel a satellite. "This vehicle is perfectly designed to do all that," Mr. Sirangelo said.

Officials at Orbital Sciences — a company in Dulles, Va., that builds and launches rockets and satellites for everything from television broadcasts to scientific research — say they are excited by the possibilities of commercial crew, but they are more cautious. Orbital, founded in 1982, was a survivor from the last boom-and-bust in commercial space.

Its space plane design is a refinement of the HL-20. Following in the pattern of tapping Greek mythology for the names of its spacecraft, Orbital calls its plane Prometheus. Orbital says development of Prometheus would cost $3.5 billion to $4 billion, which would include the cost of upgrading the Atlas V rocket and two test flights.

With enough financial support, David W. Thompson, chief executive of Orbital, is sure that his company can build and operate Prometheus. But he is less sure that his industry is at a tipping point for spaceflight to become much more common, driving down prices and opening up space to new businesses.

"I think it depends on what the demand curve really is," Mr. Thompson said. "I would say I'm highly skeptical."

ЦитироватьSierra Nevada Details Drop Plan For Dream Chaser[/size]
LOS ANGELES —Bolstered by its recent second-round NASA Commercial Crew Development Program (CCDev2) win to continue development of the Dream Chaser spaceship, Sierra Nevada Corp. is revealing new details of its plan to conduct full-scale drop tests in 2012 using the Scaled Composites-developed WhiteKnightTwo mothership.

Sierra Nevada is one of the big winners in the second round of NASA's CCDev program, netting $80 million of the total $269.3 million payout aimed at maturing concepts for private spacecraft to carry astronauts to the International Space Station and other low Earth orbit destinations. Designed for a maximum crew of seven, the Dream Chaser is a lifting body spacecraft based on NASA's HL-20 crew vehicle, and will launch on an Atlas V.

The atmospheric drop test of the full-scale vehicle, expected sometime in the second quarter of 2012, will asses handling qualities as well as stability and control during an unpowered descent to a conventional runway landing. The design of the low-speed flight control system is being fine-tuned after drop tests of a scale model were conducted in December at NASA Dryden Flight Research Center from a helicopter hovering over the dry lakebed at Edwards AFB, Calif.

Preparations for firming up the drop test from WhiteKnightTwo, which will take place from an altitude of 45,000 ft., follow last December's announcement that Virgin Galactic is supporting the Dream Chaser development. Virgin Galactic also was included in Sierra Nevada's CCDev2 proposal. The large, four-engined carrier aircraft is in development for Virgin's SpaceShipTwo sub-orbital space tourism and science vehicle, but is being actively marketed for a range of other "mothership" drop test roles.

New details of the Dream Chaser were revealed by Sierra Nevada Space Systems Group at the recent American Institute of Aeronautics and Astronautics Space Planes and Hypersonics conference in San Francisco. Integrated product team lead Russ Howard says the vehicle's hybrid rocket motor is undergoing further development work following testing for CCDev, which included three static firings in one day. "This included one vacuum start and a demonstration of a new pressure feed system," he says.

The rocket, fueled by a combination of hydroxyl-terminated polybutadiene (HTPB) and nitrous oxide, is designed "for flexibility, as it can be stopped, re-started and throttled to 100% for launch abort/escape, or 50% for fine control in nominal maneuvers. We're planning to throttle down as low as 50%, but we have demonstrated thrust down to 30% and its been very stable," Howard adds.

The Dream Chaser is expected to have a cross-range capability of 1,700 km (1,000 mi.) and with a subsonic lift/drag ratio of 4:0, a "landing will be feasible on 7,000-foot runways," he says. However, with launches currently planned from Kennedy Space Center's SLC-41 launch pad (and possibly SLC-39B after conversion), the primary landing site is Cape Canaveral's 15,000-ft. main runway.

Beyond atmospheric drop tests, further development plans include an un-piloted orbital test flight (OFT-1) boosted by an Atlas V, followed by a crewed OFT-2. The system is aiming for initial operational capability in 2015.

Но это угол установки, оптимальный для самобалансировки на сверхзвуке минимум! При дальнейшем снижении скорости полета БОР-4 становился неустойчивым, и его принудительно сваливали в штопор, спасая затем на парашюте. А у орбитального самолета "Спирали", моделью которого с некоторой натяжкой можно считать БОР-4, консоли крыла для предпосадочного маневрирования и посадки раскладывались практически горизонтально.
Получается, что американцы скопировали промежуточное положение подвижных консолей, сделав их фиксируемыми, при этом намерены спасать свой аппарат не на парашюте (как БОР-4 или Х-38 ), разумном для такого крыла, а садить его на ВПП, как ЭПОС, имеющий  разложенное крыло.
Мне нигде не попадалась инфа, как они собираются обеспечивать устойчивость и управляемость своего аппарата на дозвуковых и посадочных скоростях.

За основу брали половинку конуса. Но у HL-20 и Боров форма была совсем другая.

ЦитироватьДа, именно это я и имею ввиду. Т.е. сделать крылатый аппарат или "несущий корпус" несложно, только у последнего будут сложности с устойчивостью/управляемостью на малых скоростях и большая вертикальная скорость. Но одно дело, когда проектирование такого аппарата ведется изначально, и под это дело закладываются центровка и выбираются органы управления, и совсем другое, когда центровка/компоновка берется от аппарата, имеющего треугольное, но горизонтальное крыло малого удлинения, но при этом крыло имеет угол установки V для сверхзвуковых скоростей. Тут возникают проблемы устойчивости/управляемости на дозвуке.
Приводить в качестве решения проблемы ранние "иксы" и HL неправильно, т.к. это были исследовательские аппараты, летавшие очень хреново и тем самым доказавшие недостатки схемы, использовать которую на штатных аппаратах неразумно. Именно поэтому, я думаю, на Х-38 и пришли к компромиссу - крыло зафиксировано в гипер/сверхзвуковом положении, а посадка - на параплане.
Но у Дримчасера мы видим шасси! Вот отсюда и мой вопрос...

Strengths included reasonable development and demonstration cost estimates, and teaming with experienced and knowledgeable suppliers. Weaknesses included lack of relevant human space flight experience; failure to provide requested financial information; and lack of information on resources planned for CCDev 2 work.

III. Final Evaluation after Due Diligence
Sierra Nevada Corporation [SNC]

For the Technical Approach evaluation, the level of confidence rating remained White. There are no new strengths identified. All weaknesses were fully addressed, except for weaknesses related to little improvement in Technology Readiness Levels during CCDev 2; an overly optimistic design schedule; failure to identify abort system development as a risk; failure to demonstrate an effective and integrated S&MA organizational structure; and the proposed timing of S&MA emphasis and integration.

For the Business Information evaluation, the level of confidence rating changed from White to Green. There was one new strength identified for demonstrating a history of operational performance, stable leadership, and a market for its products and services. All weaknesses were fully addressed.

IV. Portfolio Selection Decision
Both Sierra Nevada Corporation (SNC) and Orbital Sciences Corporation proposed lifting bodies and both were highly rated in terms of their overall color ratings and strengths/weaknesses. However, SNC scored higher in business considerations and demonstrated a strong commitment to the public-private partnership associated with the Commercial Crew Program. Also, SNC's proposal showed more advancement in their CTS concept by reaching an approximately PDR level of maturity at the end of CCDev 2 compared to an SDR level for Orbital Sciences. In addition, SNC's overall CTS concept included a seven crew seat configuration (as opposed to four for Orbital Sciences) which provides flexibility for optimizing crew and cargo up-mass and down- mass by accommodating two to seven crew members and the capability to trade out crew for cargo, increasing confidence in the effectiveness of the technical approach of SNC's CTS concept. Also, Orbital's proposal featured an Atlas V variant that is one of the more robust Atlas V configurations, limiting the growth potential of the spacecraft. SNC's proposal featured a more modest Atlas V variant allowing for more mass growth, increasing the likelihood of being able to successfully develop their CTS concept.

The SNC proposal had a significant weakness in its abort system risk. There remained significant concern on the part of the PEP with respect to the development of appropriate launch abort systems requirements and launch abort system capabilities. Also, SNC did not appear to adequately recognize the importance NASA placed on this risk. However, I felt this risk could be addressed during the development, and given the advantages associated with the SNC proposal cited above, I more highly rated the SNC proposal than the Orbital Sciences proposal.

However, I felt that the proposed baseline level of investment in SNC's concept at this stage was not the most effective use of the limited funding available for the CCDev 2 effort. As each of the participants in due diligence was requested to do, SNC proposed alternate, prioritized milestones that featured a reduced government investment and maintained significant acceleration of their CTS concept. Thus, I selected this option for award.

ЦитироватьAfter selecting Boeing and SpaceX's capsules as winners in the CCDev competition, NASA turned to choosing a lifting body concept.

"Given the emphasis on diversity, I considered it important to have at least one lifting body concept in the portfolio," McAlister said, noting that while lifting bodies are more technically complex, they offer some advantages over Apollo-style capsules.

. . .

Sierra Nevada and Orbital Sciences Corp. proposed lifting bodies in the competition, and McAlister said he selected Sierra Nevada's Dream Chaser because it was further along in development and could haul more astronauts and cargo than Orbital's concept.

McAlister said Sierra Nevada's Dream Chaser design had more margin to cope with potential mass growth due to unforeseen issues in development, despite perceived risks in the Dream Chaser's abort system.

ЦитироватьCOCOA BEACH, Fla. — Sierra Nevada Corp., one of four firms working on space taxi designs for NASA, is stepping up plans to expand its work force and operations in Florida, company and state officials announced May 4.

"The goal that we have here is really quite simple — we want to take the 'Help Wanted' signs out of the windows in Russia and bring it back here," Mark Sirangelo, executive vice president of Sierra Nevada's Space Systems Group, said during an announcement here.

The Louisville, Colo.-based firm is developing a small-winged vehicle called Dream Chaser that can carry up to seven astronauts, or a mix of crew and cargo, to and from the international space station. The company so far has been awarded $125 million from NASA for design and development work, about half of which already has been paid.

Sirangelo told Space News his company has made a "significant" financial investment in the project as well, though not as much as what NASA has contributed.

Sierra Nevada has applied for economic and tax incentive packages to expand its presence in Florida, Lt. Gov. Jennifer Carroll said.

The company currently employs about 300 people in Florida on other programs. Sierra Nevada employs about 2,200 people in 16 states.

It is among several firms vying for NASA's next round of funding for the Commercial Crew Development program. The agency has $406 million to spend this year and hopes to award multiple 21-month contracts this summer worth between $300 million and $500 million for integrated design work.

If selected, Sierra Nevada plans to base its fleet of three to five spaceships at a still-to-be-determined facility at Kennedy Space Center or Cape Canaveral Air Force Station. Former space shuttle workers are being recruited to process, launch and service the vehicles, which would take off aboard a United Launch Alliance Atlas 5 rocket and land on the Shuttle Launch Facility runway.

"This is not a paper program. We are well into the manufacturing and starting to test," Sirangelo said.

Shock-waves form on launch vehicles as they approach the speed of sound and may result in regions of highly unsteady flow.....

ЦитироватьSierra Nevada Corp., one of the firms vying to build a commercial space taxi for NASA, plans a series of automated and piloted atmospheric flight tests of its lifting body Dream Chaser spacecraft beginning this summer, ultimately leading to an orbital demonstration mission in 2016, according to company managers.

The flight tests will initially prove the Dream Chaser's aerodynamic qualities using an engineering article being outfitted at Sierra Nevada's space campus in Louisville, Colo.

Using a combination of public and private funding, Sierra Nevada is developing the Dream Chaser to carry up to seven astronauts to the International Space Station and back to Earth. NASA has promised the company $125 million so far, with the bulk of the money already awarded to Sierra Nevada upon completion of predetermined development milestones.

"Our mission is very specific: to take crew and cargo to the International Space Station and to low Earth orbit," said Mark Sirangelo, Sierra Nevada's executive vice president and chairman of its space systems division.

Sierra Nevada has provided the Dream Chaser program with "tens of millions" of dollars in internal funding, but less than NASA's total investment, according to Sirangelo.

The remaining NASA funds will be released after the Dream Chaser's preliminary design review, scheduled for late May, and captive and free flight tests over Colorado and California.

"We've made amazing progress without a lot of money," Sirangelo said.

The Dream Chaser is based on the HL-20 lifting body concept studied by NASA's Langley Research Center from the late 1980s to the early 1990s. Launching into orbit on top of a United Launch Alliance Atlas 5 rocket, the spaceship will dock with the International Space Station and can stay there for more than six months. At the end of its mission, the craft will enter the atmosphere and make a piloted touchdown at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida.

A preparatory step leading to the first free flight could come as soon as the end of May, officials said, when an engineering test article will be lifted aloft over suburban Denver underneath a Sikorsky S-64 Sky Crane helicopter.

"You want to work backwards in the space industry and make sure you can land before you take off," Sirangelo said.

Steve Lindsey, Sierra Nevada's director of flight operations, said the captive carry test would verify the Dream Chaser's stability hanging underneath a helicopter, check its hang angle, drogue parachutes, and test the Sky Crane's lift capability.

Lindsey, a former space shuttle commander, said the test vehicle will be returned to Sierra Nevada's factory to receive flight control systems and a main landing gear modified from the U.S. Air Force's F-5E Tiger fighter jet. Dream Chaser's nose gear is a custom-designed skid.

Dream Chaser's space missions will use a new landing gear with electric actuators, Lindsey said.

Sierra Nevada will ship the engineering article to Edwards Air Force Base, Calif., this summer for another series of captive carry tests before ultimately releasing the craft for an automated landing. According to Lindsey, the drop tests will be performed from a CH-53 Sea Stallion or CH-47 Chinook helicopter provided by the U.S. military.

"The drops will be a straight in approach from as high as we can get," Lindsey said. "I'm hoping about 17,000 feet or so, straight into the main runway at Edwards for approach and landing."

Lindsey said the plan is to land the Dream Chaser on Runway 22 at Edwards, the base's primary concrete landing strip used by the space shuttle.

"Part of the reason we're doing this testing is because we have so many aerodynamic uncertainties with the vehicle," Lindsey said. "The shuttle had a nominal 20-degree glideslope. We're about a 23-degree glideslope, so a little bit steeper. We'll fly 300 knots down on final [approach], just like the shuttle did, and do a preflare at 2,000 feet, just like the shuttle did, drop the gear at 200 or 300 feet, just like the shuttle, and touch it down roughly at 190 knots on the runway, just like the shuttle did."

Sierra Nevada delivered the structure of the engineering test article in January, followed by a deployment test of the modified F-5E landing gear.

Sierra Nevada has also constructed avionics and flight control laboratories, plus a Dream Chaser flight simulator to practice landing the spacecraft on a runway.

The free flight test, expected in late summer, is the last milestone Sierra Nevada must complete under its ongoing agreement with NASA. The firm proposed continuing Dream Chaser's development through at least May 2014 in NASA's next round of funding.

Beyond the free flight test this summer, Sierra Nevada says further flights are contingent upon winning a monetary award from NASA.

NASA expects to award multiple companies between $300 million and $500 million in August. The agreements will run for approximately 21 months, followed by an optional period in which the space agency could select a single provider to continue with flight testing and crew transportation services.

Sierra Nevada says it can build three to five Dream Chaser spacecraft to be based at the Kennedy Space Center. The company is seeking state incentives and agreements with NASA to acquire former shuttle infrastructure at the space center, officials announced last week.

Lindsey hopes to fly the Dream Chaser for manual landing tests as soon as 2014. The former shuttle astronaut could also pilot the spacecraft on its first test flight to orbit.

"The second vehicle we build, which will be in 2014, is called our suborbital vehicle," Lindsey said. "That will have the primary flight control system in it, and it will be much closer to our orbital vehicle. All of its flights will be piloted. We'll do free flight drop tests similar to what we're doing now, except we won't be using a helicopter. We'll be flying under a wing and release or doing a tow and release [behind an airplane]."

Testing of the Dream Chaser's suborbital vehicle will include firings of the ship's hybrid rocket motors. Two of the non-toxic motors, derived from Sierra Nevada designs used on the SpaceShipOne and SpaceShipTwo space tourism vehicles, will adjust the craft's orbit in space, return it to Earth, and propel the Dream Chaser away from danger during a launch mishap.

"We're going to have our hybrid motors on the [suborbital vehicle], and we're going to use the motors to accelerate us up into the supersonic regime to get data there," Lindsey said. "The last thing we do with that vehicle, when we're done with all the pilot-in-the-loop testing, is we're actually going to put it on a simulated Atlas 5 and do a pad abort to a runway landing autonomously."

An unmanned orbital test flight and a crewed mission into orbit will follow in 2015 and 2016, according to Sierra Nevada.

ЦитироватьNarrator: Sierra Nevada Corporation's Dream Chaser flight vehicle recently passed one of its most complex tests to date with a successful captive-carry demonstration near the Rocky Mountain Metropolitan Airport in Colorado.

Backdropped by skyscraping summits, an Erickson Air-Crane helicopter lifted the full-scale spacecraft to verify proper aerodynamic flight performance.

Data from the captive-carry will help the company work toward an even more ambitious free-flight test, where the spacecraft will be dropped to evaluate the landing phase of a mission.

It's all part of proving the company's Dream Chaser could one day be capable of transporting astronauts to and from the International Space Station for NASA's Commercial Crew Program.

..........Unlike Enterprise, the tests won't involve riding atop of the Shuttle Carrier Aircraft (SCA), although they may opt to use another famous carrier aircraft, Scaled Composites White Knight Two (WK2) – although this option is yet to be confirmed, due to the need to confirm its availability during the test phase.

Mr Sirangelo noted that the testing will involve numerous runs and could involve a variety of carrier aircraft, starting with helicopters, later with other aircraft – such as White Knight Two. These initial tests will be uncrewed, to be followed by crewed tests.............

ЦитироватьWith a target a landing speed of 191 knots, Dream Chaser will touch down with its Main Landing Gear, before pitching the nose forward on to an inbuilt skid strip, as opposed to a Nose Landing Gear wheel.

Speaking of the rationale for opting to use a skid strip, SNC noted it is a simple, light, safe option. They also added that there had been some issues with the analysis of the performance of tires in the space environment and this eliminates one of the tires – with the other two tires easier to control than the nose wheel if there's a problem with one of them.

SNC noted they do not expect any crosswind limitations from the skid.

SPARKS, Nev., Aug., 3, 2012 (SNC PR) – Eren Ozmen, President of Sierra Nevada Corporation (SNC), is pleased to announce that the company's Dream Chaser® Space System has been awarded $212.5 million as part of NASA's Commercial Crew Integrated Capability (CCiCap) Program. The 21 month contract will begin in August of 2012.
Mark Sirangelo, Corporate Vice President and head of SNC's Space Systems stated, "SNC, as the owner and prime contractor for the Dream Chaser Space System, on behalf of all of our industry, academic, and NASA Center teaming partners would like to thank NASA for showing the confidence in us and for all its efforts to maintain the vital Commercial Crew Program as part of its plan for the future of space transportation. We are very pleased to have been awarded this amount of funding as part of NASA's ongoing effort to create a commercial human transportation system to low Earth orbit. This award will allow our Program to continue to make great strides in the development of the Dream Chaser Space System. We want to express our appreciation to all of those that have provided great support in our efforts, including everyone within our organization and our terrific external team partners, the NASA personnel assigned to our efforts and throughout the NASA Centers and our federal, state, and local government representatives."

SNC has integrated the efforts of its powerful team of leading aerospace companies, academic institutions, and NASA Centers to significantly advance the development of the Dream Chaser orbital crew vehicle and the associated mission, ground, and crew systems, as well as launch vehicle integration. To date, the SNC team has completed 19 milestones; including a full system Preliminary Design Review and first captive carry flight, in addition to a significant number of additional tasks. The remaining milestone under the second round of NASA funding will be an Approach and Landing Test scheduled for later this year, mirroring the first flight test of the Space Shuttle Program. The full CCiCap Program will allow SNC to complete development of the Dream Chaser Space System and transport crews to space as early as 2016.

"We are pleased to be selected to continue development of the Dream Chaser Space System and proud that NASA is showing confidence in the SNC team's ability to develop our nation's next human spacecraft. Our team will continue to work with NASA to ensure that the Dream Chaser is a reliable and safe spacecraft to carry NASA astronauts to the International Space Station," said Jim Voss, Vice President of SNC's Space Exploration Systems and Dream Chaser Program Manager. "I believe we were chosen to continue the Dream Chaser Program because we have a great design, a great team, and have demonstrated, in cooperation with our NASA Partner, that we can develop a human spacecraft in a rapid and cost effective manner."

ЦитироватьВообще у меня такое впечатление, что SNC дали денег именно потому, что пока они единственные прорабатывают "крылатик". Это скорее финансирование оригинальной концепции пилотируемого корабля.

ЦитироватьEnding his NewSpace 2011 talk, (current SNC Space Systems Chairman) Mark Sirangelo added his own story to Dream Chaser's history. Several years ago, he visited Russia and met with three of the five Russian engineers from the BOR-4 program. Unaware until then that their little lapot lived on in another country, the engineers gave Sirangelo pictures of the P-3 surveillance plane, taken by the soldier on the trawler that recovered the BOR-4. Sirangelo made a promise to them that, when Dream Chaser was finished, he would put the names of the Russian team right next to those of the American teams. And he invited all of them to Dream Chaser's first launch.

"I got a note from the daughter of one of the guys who died since I went there," Sirangelo said, "and she said that one of the last things that he wanted to do was have her send me a letter reminding me of the promise I made to put his name on the Dream Chaser when we flew. And that's what I think the space industry's all about."

ЦитироватьSierra Nevada Corporation Completes the Finance Investment Milestone for the Dream Chaser® a Month Ahead of Schedule
Published: Tuesday, Jun. 25, 2013 / Updated: Tuesday, Jun. 25, 2013 04:20 PM

SPARKS, Nev. --

Sierra Nevada Corporation (SNC) has successfully completed another Dream Chaser milestone under NASA's Commercial Crew Integrated Capability (CCiCap) agreement. The CCiCap Investment Finance milestone represents SNC's commitment to significantly invest its own dollars into the design, development and testing of the Dream Chaser Space System.

Спойлер

SNC is committed to the successful development and deployment of the Dream Chaser Space System by investing company resources in support of NASA's CCiCap program requirements. The additional funding supports the purchase of equipment, facility expansion, modifications, upgrades and the purchasing or licensing of intellectual property to support programs.

One of SNC's investments in the program is the recent opening of a new facility that houses Dream Chaser personnel along with upgraded laboratories, including a new state-of-the-art flight simulator. The new building is located in Louisville, Colo., close to SNC's Space Systems' current headquarters in the Colorado Technology Center.
 
 In addition to this recent milestone, SNC has completed three major milestones under the CCiCap agreement, including the Integrated System Baseline Review, the Program Implementation Review and the first Integrated System Safety Analysis Review. SNC completed milestone five ahead of milestone four, which is on schedule to be completed later this year. Milestone four will mark the conclusion of the flight test series that Dream Chaser is currently undergoing at NASA's Dryden Flight Research Center in Edwards, Calif.

Dream Chaser Performs Captive-Carry Test at Edwards Air Force Base




http://www.youtube.com/watch?v=XIJ4i8nJ9kw (http://www.youtube.com/watch?v=XIJ4i8nJ9kw)

ЦитироватьSparks, NV – October 26, 2013 – Today, Sierra Nevada Corporation (SNC) performed its first free-flight approach-and-landing test of the Dream Chaser® (http://www.sncdreamchaser.com/)  (http://www.sncdreamchaser.com/)spacecraft. The vehicle successfully released from its carrier aircraft, an Erickson Air-Crane helicopter, as planned at approximately 11:10 a.m. Pacific Standard Time. Following release, the Dream Chaser spacecraft automated flight control system gently steered the vehicle to its intended glide slope. The vehicle adhered to the design flight trajectory throughout the flight profile. Less than a minute later, Dream Chaser smoothly flared and touched down on Edwards Air Force Base's Runway 22L right on centerline. While there was an anomaly with the left landing gear deployment, the high-quality flight and telemetry data throughout all phases of the approach-and-landing test will allow SNC teams to continue to refine their spacecraft design. SNC and NASA Dryden are currently reviewing the data. As with any space flight test program, there will be anomalies that we can learn from, allowing us to improve our vehicle and accelerate our rate of progress. Please continue to monitor, www.SNCDreamChaser.com (http://www.sncdreamchaser.com/), for more information.

WASHINGTON — Despite a crash landing, a full-scale model of Sierra Nevada Corp.'s Dreamchaser — one of three spacecraft vying to take the space shuttle's place as NASA's means of flying astronauts to the international space station — may actually have performed well enough in an Oct. 26 test flight to clear a $15 million development milestone, according to a Sierra Nevada executive. 
"The milestone was all about the flight worthiness of the vehicle and the data from the flight and the ability for us to autonomously control the flight in the air," Mark Sirangelo, corporate vice president for Sierra Nevada Corp. (SNC) and chairman of Sierra Nevada Space Space Systems, told SpaceNews in an Oct. 28 phone interview. "The fact that the landing gear didn't go down once we hit the ground ... was not actually part of the test."
SNC has not yet decided whether to repair the Dream Chaser test craft, which does not use the same landing gear the orbital vehicle would use. Investigating what went wrong will take "a couple of weeks," Sirangelo estimated. He said the vehicle, which is now in a  hangar in Mojave, Calif., was "fully intact" after the crash.
"The pressure vessel was completely pristine, the computers are still working, there was no damage to the crew cabin or flight systems," Sirangelo said. "I went inside it myself and it was perfectly fine. There was some damage from skidding. 
"We learned everything we wanted to on this test, and learned more than we expected to learn," Sirangelo said. "We believe we've got most of the data we need [but] I can't honestly say, I just don't know yet. It's not going to affect our schedule in the long term [but] It might affect whether we do another free flight test this year or next year. We're still assessing that."
SNC's $227.5 million Commercial Crew Integrated Capability Space Act Agreement with NASA, awarded in August 2012, calls for a minimum of one drop test. It will ultimately be up to NASA to decide whether the flawed landing — caused when the test vehicle's left landing gear failed to deploy — necessitates a do-over of the Oct. 26 flight.
NASA spokesman Trent Perrotto, reached by email Oct. 28, had no immediate comment about the test. 
If more test flights are required, "we think the Engineering Test Article is flyable again," Sirangelo said. However, If SNC elects not to repair the craft, which took several months to build, it could construct an "interim aeroshell" at the Michoud Space Assembly Facility near New Orleans for more test flights, Sirangelo told SpaceNews. 
The orbital version of Dream Chaser, meanwhile, has been under construction for "several months," Sirangelo said. 
At about 2:10 p.m. Eastern time on Oct. 26, the so-called Dreamchaser Engineering Test Article was dropped from an altitude of about 4 kilometers by a helicopter. The craft then autonomously descended to the runway at the Dryden Flight Research Center at Edwards Air Force Base in California. Conditions were spot-on for the flight, which clocked in at just over one minute, until touchdown. After Dreamchaser hit the runway at about 300 kilometers per hour, its left-side landing gear failed to deploy, sending the craft on a skid, Sirangelo said.
Sierra Nevada is developing Dream Chaser, which would launch atop a United Launch Alliance Atlas 5, with the smallest of three awards given out last year in the $1.1 billion third round of NASA's Commercial Crew Program. The program's objective is to produce one commercially designed spacecraft to take astronauts to and from the international space station from U.S. launch sites starting in late 2017.
Boeing Space Exploration of Houston got $480 million to develop its CST-100 space capsule, also to be launched on Atlas 5, and Space Exploration Technologies Corp. got $440 million to work on its crew-rated Dragon capsule, which would launch atop the company's Falcon 9 1.1 rocket. 
NASA now plans to solicit proposals for the fourth round of the Commercial Crew Program — which will be funded through a contract that permits NASA to issue task orders for routine crew flights — on Nov. 19. A draft solicitation has been circulating since July. Proposals are due Jan. 22, and awards are expected in September 2014, according to a NASA document posted online Oct. 25.

ЦитироватьDream Chaser Forward Plan:

Mr. Sirangelo also took time to update the current status of the program, noting the Dream Chaser Engineering Test Article (ETA) is currently on her way back to SNC's base in Colorado, following her test flight last year.

With all the main objectives passed with flying colors, Dream Chaser passed the final NASA Commercial Crew Development Round 2 (CCDev-2) milestone requirement.

Z7Although the landing suffered a failure of the port landing gear, resulting in the vehicle hurtling off the runway, in turn causing a large amount of cosmetic damage, Mr. Sirangelo pointed out the test timeline is actually a few months ahead of schedule, thanks to the multitude of data collected during her debut flight.

The ETA will now be upgraded for one or two more flights – listed as ALT-1 and ALT-2 – beginning later this year. Both will once again be conducted at the Dryden Flight Research Center in California.

*Click here for more Dream Chaser articles*

"(The ETA) is fully repairable, the primary structures were not damaged," added the SNC boss. "The vehicle is on its way back here for its upgrades. We expect to be conducting air operations with this vehicle again this year."

Dream Chaser ETA Cockpit via L2The upgrade of the ETA will result in her changing call signs from the Block 0 to the Block 0.5.

A final Californian test will involve a crewed high altitude approach and landing in 2015, with the ETA upgraded to the final Block 1 configuration.

This upgrade will overlap with the final construction work on the Orbital Test Vehicle (OTV) version of the Dream Chaser, which will ride atop of an Atlas V for an uncrewed test flight into space.

This vehicle is currently being manufactured at the Michould Assembly Facility (MAF) in New Orleans, per their association with Lockheed Martin.

Crew boarding Dream ChaserKnown as OFT-1 (Orbital Test Flight -1), Mr. Sirangelo noted this should take place in late 2016, with OFT-2 following in early 2017, carrying two crewmembers to the ISS for docking.

"We expect the first orbital launch to occur in 2016 – which will be an unmanned autonomous mission and we're expecting our first human certification mission in 2017," he added.

All of these test flights will lay the foundations for the final fully operational version, the Dream Chaser Space System (DCSS), which will be the baseline design that can foster several variants to account for potential NASA, ESA, Military, and customer specific applications.

ЦитироватьВАШИНГТОН, 24 января. /Корр. ИТАР-ТАСС Иван Лебедев/. Американская частная компания Sierra Nevada планирует осуществить первый испытательный полет своего космического корабля Dream Chaser в ноябре 2016 года и намерена использовать для его запуска, а также посадки космодром на мысе Канаверал (штат Флорида). Об этом сообщает NASA, заключившее с Sierra Nevada соглашение об использовании инфраструктуры своего главного космодрома.

Предполагается, что Dream Chaser будет готовиться к старту в гигантском ангаре на мысе Канаверал. В этом же помещении корпорация Lockheed Martin ведет сборку корабля Orion, который NASA в перспективе планирует использовать для полетов на астероиды и на Марс.

Сотрудничество между ними не ограничится лишь соседством в сборочном цехе. Запуск Dream Chaser будет осуществлен с помощью ракеты-носителя "Атлас-5", которая создана Lockheed Martin и используется на рынке коммерческих космических услуг компанией United Launch Alliance, учрежденной совместно с другим лидером авиакосмической промышленности США - Boeing.

Взлетать "Атлас-5" с Dream Chaser будет с одной из стартовых площадок космодрома, а приземляться кораблю предстоит на 5-километровой посадочной полосе на мысе Канаверал, которая раньше использовалась шаттлами. Новый аппарат по форме напоминает эти корабли NASA, отслужившие свой век и ставшие теперь музейными экспонатами.

По замыслам руководства Sierra Nevada, в состав которого входят, в частности, бывшие астронавты, новый корабль будет использован для полетов на низкую околоземную орбиту, в том числе на Международную космическую станцию. Его экипаж будет состоять из семи человек.

NASA, выделившее в течение последних лет на создание этого аппарата в общей сложности около 350 млн долларов, рассчитывает задействовать его для доставки на МКС своих астронавтов и полезных грузов. С тех пор как шаттлы были отправлены в отставку, космическое ведомство США пользуется в этих целях услугами Роскосмоса, арендуя места на российских "Союзах".

ЦитироватьLockheed Martin Space Systems' Jim Crocker, who oversees the company's civil space business, said its involvement in the Dream Chaser program is a continuation of Lockheed Martin's long history at Michoud.

After decades of building the space shuttle's external fuel tanks at the site, the company in 2011 began working on the Orion Multi-Purpose Crew Vehicle program, a big project that continues at Michoud.

Crocker said bringing the commercial Dream Chaser program to the site helps balance out peaks and valleys in the Orion work.

Predicting that the new vehicle "will be the first of a series" of Dream Chasers that Lockheed will build at the site, he added: "The lights are back on at Michoud Assembly Facility."

During the final years of the U.S. space shuttle program, when more than 3,000 people worked at Michoud, some observers feared that the site might indeed go dark. But worries eased somewhat when NASA announced that Boeing would build an advanced heavy-lift launch vehicle to carry the Orion into deep space.

Today, Boeing is building the Space Launch System at Michoud, under the same roof where Lockheed Martin is fabricating the Orion structure.

We are flying on an Atlas V 412. The first stage has one strap on solid. We are lighter [compared to CST-100] and don't need a second solid. The second stage uses a dual engine Centaur."

ЦитироватьHow long can Dream Chaser stay in space? Describe its unique capabilities as a research laboratory and more.

"Dream Chaser has the capability of staying on orbit for over a year, or longer, uncrewed. So once it gets up to the station the idea is we could be a supplemental research vehicle that could have dedicated equipment on it, because we can fly it back home."

"For example, you might want to test something on the station that isn't testable on the station right now, using different kinds of instruments, sensors or pods for the experiments. We could outfit Dream Chaser for that and let it be on orbit for whatever duration it needed. And then bring it back with the experiments."

"And then we could outfit the vehicle for the next type of experiment. That's for something you can't do for the space station."

Well, one year or more on orbit for Dream Chaser would be considerably longer than the other space taxis, like Dragon V2 and CST-100, which meet NASA's minimum requirement for a stay in space of about one-half year or so.

ЦитироватьDescribe its capability as a lifeboat and for quick getaways, and the resulting science implications?

"We have a very unique station capability that no one else has. We can come back fr om the station in six to eight hours generally and land at a runway in America—at less than two Gs!"

"For example if one is transporting critical experiments or sick astronauts or something that really requires special or quick handling, we can do that more rapidly than anyone in the world. And we can bring it back to a runway in Florida (KSC) or conceivably in Texas [near NASA's Johnson Space Center or elsewhere] or some other place in the U.S."

"Whereas our other competitors are landing in the water or far out in the desert somewhere. And they are coming in as a capsule does, at considerably higher G forces."

"So if you are working on the next breakthrough in bioscience, and you want to make sure you bring it home, what would you rather do? Bring it home in a quarter of the time and a third or half the G forces to a runway in the U.S. versus going out to the ocean or desert somewh ere!"

"So that's the type of thing we feel we have an advantage on."

"To date, SpaceX has taken something like 30 or more hours to return samples after the Dragon's splashdown."

ЦитироватьWell, in that case of an unmanned version of Dream Chaser, then it seems like you could bid on NASA's next CRS (Commercial Resupply Services) contract, is that right? Boeing is also considering that option. (Read the interview with Boeing's Chris Ferguson here.)

"Yes, we could!"

ЦитироватьWhat is the projected turnaround time between flights?

"We think about 45 days to 60 days. It also depends on rocket launch slot availability. Part of it is you can be ready to fly, but do you have the launch [pad] availability. So we think we could do 4 to 6 flights per year on a vehicle, to be conservative."

SNC со своим Dreamом Chaserом был уже изначально в пролёте когда НАСА заявило о одноразовости коммерческих КК, только для чего ради было мусолить эту тему

Dream Chaser не был выбран по четырем основным причинам:

1. наиболее рискованное в техническом плане предложение (в том смысле, что возни с кораблем сделаным по схеме «несущий корпус» в любом случае будет намного больше, чем с любой из капсул.

2. СРОКИ. В свете стремительно ухудшающихся отношений США и России, риск задержек связанных с доводкой DC до стадии когда на нем можно будет реально отправлять людей к ISS выглядит совершенно неприемлимым. Редкая неделя проходит без очередного пинка NASA по поводу того, что они платят 70 миллионов за место в Союзе, используют РД-180 в Атласе, профукали пять лет с Ares, и т.д. и т.п., так еще и последние новости по поводу возможного переноса центра тренировки космонавтов в Крым подлили масла в огонь.

3. Из трех претендентов, у SNC меньше всего ресурсов (и как следствие, в случае возникновения серьезных проблем будут срывы выполнения этапов проeкта и, возможно, нужда в дополнительных финансовых вливаниях).

4. Использование Атлас-5 с его РД-180 и отсутствие собственной ракеты-носителя.

Вдогонку: у SNC система аварийногом спасения корабля наиболее сложная и менее всего проработана. Для DC требуется специальная, еще не существующая модификация Атласа (402).

SpaceX и Boeing получат контракты НАСА по доставке астронавтов на МКС.

Сегодня ночью на специальной пресс-конференции американское космическое агентство подвело итоги третьего этапа программы CCDev (Commercial Crew Development). Целью этой программы является создание частных пилотируемых кораблей.

 Компании SpaceX, Boeing и Sierra Nevada, прошедшие отбор на предыдущих этапах, под контролем космического агентства разрабатывали собственные транспортные средства для доставки экипажей на МКС. По мере достижения определенных ключевых шагов НАСА выдавало им безвозмездные субсидии. Текущий третий этап программы должен был завершиться в сентябре 2014 года, однако ранее НАСА продлило его до марта 2015 года, поскольку только Boeing успешно справилась с заявленной программой разработки в срок.

Две компании, выбранные сегодня НАСА, получат заказ на доставку американских астронавтов на МКС. Суммарная стоимость контрактов, которые включают в себя обязательство осуществить помимо испытательного полета от двух до шести регулярных полетов четырехместного корабля к космической станции, составит 6,8 млрд долларов (2,6 млрд SpaceX, 4,2 млрд Boeing). Предполагается, что регулярные полеты к станции начнутся в конце 2017 года. SpaceX, считавшаяся фаворитом гонки, разрабатывает капсульный корабль Dragon и собственную ракету-носитель Falcon 9. Капсульный корабль компании Boeing предполагается выводить на орбиту на ракете-носителе Atlas V разработки United Launch Alliance (ULA) – совместного предприятия Boeing и Lockheed Martin. Сейчас ULA испытывает проблемы из-за охлаждения отношений между Россией и США. Хотя поставка двигателей РД-180 для первых ступеней ракет Atlas V продолжается буквально в дни, в США было принято политическое решение найти замену российским двигателям. На днях Boeing заключила союз с аризонской компанией Blue Origin, которая в прошлом претендовала на участие в гонке за «пилотируемый» контракт НАСА, однако сильно отстала от конкурентов. Теперь Blue Origin должна будет на основе своих технологий создать новый двигатель – по слухам, метаново-кислородный – на замену РД-180. Ранее эта компания самостоятельно работала над водородным двигателем.

Третья компания, упомянутая выше Sierra Nevada Corporation (SNC), не получила контракт НАСА. SNC занимается разработкой мини-шаттла Dream Chaser – многоразового космического корабля с планерной системой посадки. Для его вывода в космос планируется использовать все ту же ракету Atlas V разработки ULA. Ранее компания SNC уже заявляла, что потеря контракта НАСА не будет означать прекращение работы над проектом. Существовали слухи, что для того, чтобы дополнительно поддержать проигравшую компанию, космическое агентство подготовило для нее «утешительный приз» - дополнительный небольшой контракт. В сегодняшней пресс-конференции администратор НАСА Чарльз Болден поблагодарил все компании, участвовавшие в программе CCDev, но ничего не сказал о дополнительных контрактах.

Компания SNC опубликовала заявление, в котором выразила разочарование решением НАСА. SNC воздерживается от обсуждения дальнейших планов относительно проекта Dream Chaser до проведения дополнительных консультаций с космическим агентством,

IRENE KLOTZ, SPACEFLIGHT CORRESPONDENT
05 JANUARY 2015, 20:36 UTC

Sen—Sierra Nevada Corp lost its challenge to NASA's award of contracts worth $6.8 billion to competitors Boeing and Space Exploration Technologies (SpaceX) for spaceships that can carry astronauts—and potentially tourists—to the space station.
Sierra Nevada protested NASA's decision, announced in September, to the U.S. Government Accountability Office (GAO). The Colorado-based company argued that its price was $900 million less than Boeing's, despite comparable levels of technical maturity.
The GAO disagreed with Sierra Nevada's contention that NASA broke its procurement guidelines in favoring schedule assessments over price.
"Contrary to Sierra Nevada's assertions, the RFP (Request for Proposals) clearly advised offerors that their proposals would be evaluated against the goal of certification by the end of 2017," Ralph White, GAO's managing associate general counsel for procurement law, wrote in a statement issued Monday.
"GAO disagreed with Sierra Nevada's arguments about NASA's evaluation, and found no undue emphasis on NASA's consideration of each offeror's proposed schedule," White added.
Sierra Nevada said it is evaluating the GAO decision.
"While the outcome was not what SNC expected we maintain our belief that the Dream Chaser spacecraft is technically very capable, reliable and was qualified to win based on NASA's high ratings of the space system," corporate vice president Mark Sirangelo said in a statement.
NASA said it was pleased with the GAO's decision.
"The case remains under the protective order and blackout until the GAO releases its decision," NASA said in a statement.
Sierra Nevada previously said it would continue development of Dream Chaser, albeit at a slower pace than if it had continued financial backing from NASA.
The company is vying against Boeing, SpaceX and Orbital Sciences to fly an unmanned version of Dream Chaser for station cargo runs. NASA is due to announce its next round of Commercial Resupply Services contracts this spring. SpaceX and Orbital Sciences currently handle the work, under contracts worth a combined $3.5 billion.
Sierra Nevada also is working with Paul Allen's-backed space startup Stratolaunch to develop a smaller version of Dream Chaser that can be air-launched to carry two or possibly three passengers to orbit.

    As explained in our decision, in this procurement, Sierra Nevada offered its Dream Chaser crew transportation system (a lifting body spacecraft), launched using United Launch Alliance's Atlas 5 launch vehicle, and landed horizontally on normal runways.  Sierra Nevada's price was $2.55 billion.
    Boeing offered its CST-100 crew transportation system (a capsule spacecraft), also launched using United Launch Alliance's Atlas 5 launch vehicle, and landed using parachute and airbag systems for hard-surface landings, or contingency water landings.  Boeing's price was $3.01 billion. 
    SpaceX offered its Crew Dragon crew transportation system (also a capsule spacecraft), launched using SpaceX's Falcon 9 launch vehicle, and landed using parachutes and propulsive soft landing systems for hard-surface landings, or contingency water landings.  SpaceX's price was $1.75 billion.
.............
In making its selection decision, NASA concluded that the proposals submitted by Boeing and SpaceX represented the best value to the government.  Specifically, NASA recognized Boeing's higher price, but also considered Boeing's proposal to be the strongest of all three proposals in terms of technical approach, management approach, and past performance, and to offer the crew transportation system with most utility and highest value to the government.  NASA also recognized several favorable features in the Sierra Nevada and SpaceX proposals, but ultimately concluded that SpaceX's lower price made it a better value than the proposal submitted by Sierra Nevada.
GAO disagreed with Sierra Nevada's arguments about NASA's evaluation, and found no undue emphasis on NASA's consideration of each offeror's proposed schedule, and likelihood to achieve crew transportation system certification not later than 2017.  GAO also noted that, contrary to Sierra Nevada's assertions, the RFP clearly advised offerors that their proposals would be evaluated against the goal of certification by the end of 2017.

SNC remains fully committed to being a part of returning world-class human spaceflight and enhanced cargo capabilities to low-Earth orbit. In doing so, SNC firmly believes that the Dream Chaser will play a central role in shaping the future of space transportation with its unique capabilities which address a wide spectrum of needs. To that end, SNC has submitted its response to NASA's Commercial Cargo Resupply Services 2 procurement and will continue to support that effort while maintaining its existing mutually beneficial and long-term relationship with NASA.

SNC also plans to further the development and testing of the Dream Chaser and is making significant progress in its vehicle design and test program. In addition, SNC is continuing to expand its existing, while developing new, partnerships domestically and abroad in order to expand the multi-mission flexibility of the system, reduce overall long-term costs of the vehicle and ensure long-term affordability and sustainability for the Dream Chaser. Customers worldwide will benefit from multiple commercial space transportation providers for commercial space access, research and operations.

ЦитироватьSierra Nevada Hopes Dream Chaser Finds "Sweet Spot" of ISS Cargo Competition

WASHINGTON — Sierra Nevada Corp., looking to rebound from a failed commercial crew bid, said March 17 it has proposed to NASA a variant of its Dream Chaser vehicle for shuttling cargo to and from the International Space Station.
At a press conference during the Satellite 2015 conference here, company officials offered details of its Dream Chaser Cargo System, based on the Dream Chaser vehicle the company had been developing for NASA's commercial crew program.
"We believe that it's the best cargo system that currently exists or will exist, because it's capable of meeting all of NASA's cargo requirements in the same system," said Mark Sirangelo, corporate vice president and head of Sierra Nevada Space Systems.
The cargo version of Dream Chaser features two major design changes from its crew version. Sierra Nevada plans to develop a small cargo module attached to the aft section of the winged vehicle. This cargo module, equipped with solar panels, will accommodate both internal and external cargo.

The Dream Chaser's wings will also be able to fold up for launch. This allows the vehicle to fit within payload fairings 5 meters in diameter currently used by the Atlas 5 and Ariane 5 launch vehicles. The crewed version of Dream Chaser, by comparison, was not designed to be encapsulated in a fairing and thus did not need foldable wings.
This vehicle, company officials said, meets or exceeds all the requirements NASA laid out for the Commercial Resupply Services 2 (CRS-2) competition for transporting cargo to and from the ISS. The vehicle can transport 5,000 kilograms of pressurized cargo and 500 kilograms of unpressurized cargo to the station. It can bring back 1,750 kilograms of cargo within Dream Chaser, and dispose of an additional 3,250 kilograms in the cargo module, which jettisons and burns up on re-entry.
"There's an important sweet spot in the amount of cargo you can bring up to the space station as well as return," said Steve Lindsey, senior director of space exploration systems at Sierra Nevada. Cargo vehicles, he said, should be large enough to minimize the number of flights needed to keep the station supplied, but not so large they are difficult to operate. "We think we've hit that."
Sierra Nevada also hopes to convince NASA that Dream Chaser's unique design — it is the only vehicle competing for the CRS-2 contracts that can land on a runway — makes the system worthwhile. "There are many capsules in the world, but there's really one vehicle like Dream Chaser," Sirangelo said. "We believe in a mixed fleet."
The CRS-2 competition is a fallback for Sierra Nevada after it lost to Boeing and SpaceX for commercial crew contracts NASA awarded in September 2014. The company filed a protest with the U.S. Government Accountability Office regarding those contracts, but that protest was denied in January.
Sirangelo said that the cargo version of Dream Chaser benefits from several months of additional work the company did between the deadlines for the commercial crew proposals in January 2014 and the CRS-2 proposals in December. "We have continued to improve the vehicle," he said. "The areas that were of concern we have addressed."
While developing the cargo version of Dream Chaser, Sirangelo said that the company has not abandoned plans for a crew version. "While we're leaning forward on the cargo autonomous version here, everything that we're doing in this vehicle is transferable to a future crew vehicle," he said.
Although Sierra Nevada lost the NASA commercial crew competition, it is still working toward the final milestone of its earlier commercial crew award from NASA, a second glide test of a Dream Chaser engineering test vehicle. That glide test is planned for later this year, Sirangelo said.
Sierra Nevada joins at least four other companies in the CRS-2 competition. On March 12, Lockheed Martin announced it submitted a CRS-2 proposal, offering a system that includes a reusable space tug. Boeing and Orbital ATK said in December that they also submitted CRS-2 bids.
SpaceX, which, like Orbital ATK, has contracts today to transport ISS cargo, had previously declined to confirm that they also bid on CRS-2. However, SpaceX President Gwynne Shotwell, speaking at a luncheon at the conference March 17, tipped the company's hand.
"Oh, most definitely," she said when asked if the company bid on CRS-2. That proposal involves the use of SpaceX's Dragon spacecraft, but Shotwell did not provide additional details.

One More Time: Dream Chaser / Sierra Nevada Corporation
Sierra Nevada Corporation formally introduced the latest variant of its oft proposed but thus far underloved Dream Chaser space plane on Tuesday, March 17th. It is intended to compete for NASA's Commercial Resupply Services 2, (CRS2) contract to serve the International Space Station.
Unlike the manned Dream Chaser which comprised SNC's proposal for NASA's Commercial Crew Program, winning funding in the first three rounds, but failing to make the final cut, the cargo only Dream Chaser is a different take on a platform whose heritage stretches all the way back to the Soviet Union's Buran Shuttle program.
(http://innerspace.net/wp-content/uploads/2015/03/dreamchaserfold.jpg) (http://innerspace.net/wp-content/uploads/2015/03/dreamchaserfold.jpg)
It's wings are now designed to be folded so that it can fit within the space of a standard 5.2 meter payload fairing, a change which significantly improves its adaptability to a wider range of launch vehicles including Atlas V, Delta Heavy, Ariane V, Falcon 9 and Japan's H-II.
In meeting NASA's need for externally mounted, unpressurized payloads, the new Dream Chaser now sports an aft mounted "cargo trailer" featuring Teledyne Brown Engineering Flight Releasable Attachment Mechanisms (Frams).
Lacking any accommodations for crew, and with seats, internal elements and even windows removed, SNC says the new version meets all of NASA's cargo requirements for both up and down mass.
As with all versions of the mini-shuttle, whether the original commercial crew proposal, the smaller two or three person variant which would lift off aboard Paul Allen's StratoLaunch/Thunderbolt project, or possible European or Japanese launched models, one of Dream Chaser's main attributes, the ability to perform a minimally disruptive 1.5 G landing at nearly any large commercial airfield remains perhaps its best feature.
Will NASA finally give the go ahead to this latest, and perhaps final version of Dream Chaser?  We won't know until sometime over the summer, but with five companies, including the current providers SpaceX and Orbital-ATK, as well as aerospace giants Boeing and Lockheed Martin all now pursuing what are considered to be two slots, Dream Chaser's glide to the runway soft landing architecture, flavored with a healthy dose of nostalgia, may well be its last, best hope.

ЦитироватьЧастный шаттл «Dream Chaser» однажды может приземлиться в Хьюстоне

Космический корабль в форме шаттла, построенный частной компанией, однажды может совершить посадку на обычном аэродроме. Об этом сообщили представители компании-разработчика Sierra Nevada.
Шаттл «Dream Chaser», как ожидается, продолжит летные испытания в конце этого года. Космический аппарат будет использовать космодром в аэропорту Эллингтона в Хьюстоне в качестве посадочной площадки. Как сообщили представители корпорации Sierra Nevada, международный аэропорт Эллингтон получил разрешение на использование в качестве космодрома.
«Соглашение с Хьюстонским аэропортом позволит нам реализовать все достоинства космического корабля «Dream Chaser». Это даст возможность доставлять в Хьюстон грузы и материалы, представляющие ценность для ученых, прямо из космоса», - говорится в сообщении Марка Сиранджело, главы корпорации Sierra Nevada.
Начиная с ноября, компания занималась поисками аэропорта, в котором шаттл Dream Chaser сможет совершить посадку. Как раз в то время результаты исследования были представлены на конференции по аэронавигации Space Traffic Management в Университете аэронавтики Эмбри-Риддла.
Как заявляют представители компании Sierra Nevada, для того чтобы шаттл мог приземлиться, место посадки должно отвечать ряду стандартов и требований.
Первоначально предполагалось, что шаттл «Dream Chaser» будет доставлять астронавтов на Международную космическую станцию и обратно на Землю. Компания получила миллионы долларов от НАСА и конкурентных коммерческих компаний. Но в 2014 году проект не был включен в программу финансирования космического агентства. Вместо этого НАСА продолжило финансировать проекты компаний SpaceX и Boeing, которые также нацелены на отправку астронавтов на космическую станцию.
Компания Sierra Nevada выдвинула жалобу, которая уже в январе была отклонена Главным бюджетно-контрольным управлением США. В комментарии говорилось, что «предложения компаний Boeing и SpaceX являются более выгодными».
Согласно последним данным, в настоящее время компания планирует использовать шаттлы «Dream Chaser» для доставки грузов на космическую станцию. Как ожидается, испытания космического корабля возобновятся позднее в 2015 году.

ЦитироватьDope on a Rope 2: Development of a Dream Chaser Aero Tow Simulation
 
Armstrong innovators have developed a lifting-body aero tow simulation to determine feasibility and procedures for towing the Dream Chaser Flight Test Vehicle (FTV) to an altitude of 30,000 feet. The Dream Chaser FTV is a full-scale, full-weight, single-seat, manned glide test spacecraft and was designed to conduct approach and landing tests. The aero tow concept calls for a large transport-size jet aircraft to tow a piloted commercial re-entry vehicle into the air with a long robust towline. At a predetermined altitude, the re-entry vehicle separates from the tow aircraft and is landed by the astronaut on board. The tow concept was successfully demonstrated in the late 1990s in the Eclipse Project with F-106 and C-141 aircraft.
"Dope on a Rope" was the unofficial Eclipse Project name, a moniker developed in jest to teasingly poke fun at the intelligence of the project pilot. The name stuck, and "Dope on a Rope 2" has been adopted as the unofficial project name for the follow-on work. Work to date: The Armstrong team linked an existing simulation of the HL-20 lifting-body aircraft and a C-17 to determine feasibility. The simulation has been updated with models of the Dream Chaser FTV, and a cockpit with representative windows has been built. The simulation is now being used to develop tow profiles and procedures, evaluate control law changes, and determine potential tow vehicles. It is also being used to validate the rope model for stability and control analysis. Looking ahead: An important role of the simulator is to evaluate different aircraft as Dream Chaser tow planes. Simulations of potential tow aircraft can be linked to evaluate performance and tow efficiency. When a tow aircraft is selected, the simulation will be used to develop tow techniques and procedures.
Partners: Sierra Nevada Corporation and U.S. Air Force

"As a result of evaluations in the Aero Tow Simulator, Sierra Nevada Corporation has made Aero Tow the primary method of getting the Dream Chaser FTV to altitude for the approach and landing testing to be performed in 2015-2016. The Aero Tow Simulator will play a vital role in developing towing techniques and procedures, tow mode flight control development, and astronaut training.

Dream Chaser's design allows unassisted crew egress at any landing site without the need for special equipment. This operation nominally occurs after the vehicle has been towed off the runway. The minimum equipment needed to quickly remove the vehicle from the runway is enabled by the low toxicity and low hazard levels of the Dream Chaser design, thus minimizing the impact on day-to-day operations at a public-use landing site.

In anticipation of a second phase of flight testing, Sierra Nevada Corporation's (SNC) Space Systems has announced significant updates to two Dream Chaser®  spacecraft currently in development. The spacecraft are the atmospheric engineering test article (ETA) and the advanced composite orbital vehicle, which when tested will undergo a suborbital and orbital flight regimen, respectively. SNC's Mark Sirangelo provided a program update at the International Symposium for Commercial and Personal Spaceflight (ISPCS) in New Mexico.

"The SNC team is readying the ETA in order to begin the second phase of atmospheric flight testing early next year and our strategic partner, Lockheed Martin, is leveraging best practices in tooling and composites to manufacture the first orbital Dream Chaser spacecraft," said Mark. N. Sirangelo, corporate vice president, SNC's Space Systems. "Both efforts have been ongoing simultaneously and we are very pleased with the progress to date."

Since flight test phase one, in which SNC's Dream Chaser ETA successfully returned trajectory data of the flight profile, SNC has made significant structural and systems improvements to the ETA including the composite wings and aeroshells. SNC also invested heavily in maturing the spacecraft orbital avionics, guidance navigation and control, the flight software, and employed a number of new processes, all of which will be used on the orbital vehicle as well. Finally, the advanced orbital Thermal Protection System (TPS), announced in June, was installed on the ETA skid in order to do advanced testing of the actual orbital TPS in this important area.

"The Dream Chaser ETA is currently scheduled to arrive at Armstrong Flight Research Center in early 2016 in order to begin the second phase of atmospheric flight test."

In parallel to the ETA upgrade, SNC has made significant progress on the build of the first Dream Chaser orbital vehicle manufactured by Lockheed Martin. Lockheed Martin is leveraging best-practices in composite manufacturing from the Skunk Works®, its advanced development programs division, as well as its extensive experience in manufacturing and assembly from the F-35 Lightning II.

Lockheed Martin recently completed the Dream Chaser orbital cabin assembly, marking a significant milestone in the construction of this vehicle.  This assembly is the largest high-temperature unitized structure ever fabricated at U.S. Air Force Plant 4. The assembly utilized three-dimensional woven joints, to integrate internal frames with external carbon skins in a single co-bond operation, meaning nearly all fasteners on this critical cabin assembly are eliminated. This state-of –the-art approach to design and manufacturing is a highly efficient and affordable design solution.

"Upon completion, the Dream Chaser orbital vehicle will be the most advanced composite structure ever built. We look forward to Dream Chaser becoming the world leader in this area and to its first orbital flight," said Sirangelo.

Американская компания Sierra Nevada Corporation (SNC) продолжает разработку космического корабля с планерной системой посадки Dream Chaser, начатую в 2010 году. Dream Chaser был единственным участником программы создания коммерческих пилотируемых кораблей CCDev, который был выполнен по схеме планера. Остальные претенденты – Dragon от SpaceX, CST-100 (Starliner) от компании Boeing и первоначальный корабль Blue Origin (он первым выбыл из конкурса) – были выполнены в классической капсульной форме.

Сейчас будущее корабля Dream Chaser весьма туманно. Первый удар по этому проекту SNC был нанесен в октябре 2013 года. Во время посадки после испытательного полета корабль перевернулся и загорелся из-за нераскрывшегося шасси. Новые летные испытания, которые планировались в 2014 году, так и не состоялись. А в сентябре 2014 года проект корабля Dream Chaser выбыл из конкурса НАСА на создание пилотируемого низкоорбитального транспорта. Контракты достались компаниям Boeing и SpaceX.

Несмотря на то, что финансирование со стороны НАСА получить не удалось, разработчики приняли решение не закрывать проект. Первым шагом стала кооперация с компанией Stratolaunch Systems Пола Аллена, анонсированная в ноябре прошлого года. Stratolaunch Systems разрабатывает большой двухфюзеляжный самолет, несущий легкую ракету, для запуска на орбиту небольших грузов. Согласно заявлению двух компаний, SNC разработает для пусковой системы Stratolaunch уменьшенную грузовую версию своего корабля. В отличие от остальных средств запуска, он сможет не только доставлять грузы на орбиту, но и возвращать их оттуда на Землю. Стоит отметить, что насчет реализуемости масштабированного варианта Dream Chaser высказывались сомнения.

Позднее у крылатого корабля появился еще один шанс. Сейчас для доставки грузов на МКС НАСА пользуется услугами компаний Orbital ATK и SpaceX. В декабре 2014 года НАСА объявило новый конкурс на снабжение МКС, в котором, наряду с другими компаниями, вновь приняла участие SNC. Отмечается, что полномасштабный грузовой вариант корабля сможет доставлять на станцию до 5 т припасов.

В среду 7 октября компания SNC объявила, что планирует возобновить полеты испытательной модели корабля Dream Chaser в начале 2016 года. Работа над созданием летного образца корабля продолжается в компании Lockheed Martin, которая является субподрядчиком и стратегическим партнером SNC. «Мы очень довольны прогрессом, который был достигнут по обоим направлениям». – заявил вчера Марк Н. Сиранджело, вице-президент SNC по космическим системам. – «Прибытие тестового аппарата Dream Chaser в Летный испытательный центр им. Армстронга для прохождения второго этапа атмосферных летных испытаний запланировано на начало 2016 года». На этот раз тестовый аппарат будет оборудован новым шасси, изготовленным специально для него, а не модифицированной версией шасси с военного самолета, которая привела к аварии в 2013 году.

SNC рассматривает множество вариантов ракеты-носителя для запуска своего корабля, включая даже европейскую ракету Ariane 5 и Falcon 9 компании SpaceX, однако фаворитом остается Atlas V компании ULA, давнего партнера SNC.

Получение контракта на снабжение МКС может вдохнуть в проект корабля Dream Chaser новую жизнь. С практической точки зрения, НАСА не нужен еще один низкоорбитальный грузовой корабль, но стратегически сохранение технологий планерной посадки имеет смысл.

The landing gear malfunction during the Saturday drop test sent the Dream Chaser prototype skidding off the runway, Sirangelo said
"It exited off the runway fairly quickly a few seconds after the one landing gear failed to come down," Sirangelo said.
As for damage, Sirangelo said that the space plane's pressure vessel — which would house the crew cabin — was not damaged, with onboard computers still working even after the skid to a full stop.
"The crew compartment was completely intact," and pilots would have walked away from the landing incident, Sirangelo said. "We found out how tough the vehicle really was. Everything inside the vehicle is completely the way it was," in pre-drop condition, he added.
....
The Dream Chaser "got beat up a bit," Sirangelo said, but came to rest on its normal horizontal position on its main landing skids. "It's not in pieces. It's going to be flyable again."

ЦитироватьВ Европейском космическом агентстве (ЕКА) с энтузиазмом восприняли решение НАСА использовать крылатый пилотируемый аппарат Dream Chaser для доставки грузов на Международную космическую станцию.
14 января 2016 года американское космическое агентство НАСА выбрало компанию Sierra Nevada Corporation с их грузовой версией корабля Dream Chaser в качестве одного из трёх победителей конкурса по второй фазе программы снабжения Международной космической станции. Компании гарантируются как минимум шесть грузовых полетов к МКС в период с 2019 по 2024 года.
Эта компания разрабатывает пилотируемый корабль многократного использования под названием Dream Chaser.
С точки зрения ЕКА это хорошая новость, поскольку агентство имеет соглашения о сотрудничестве с Sierra Nevada Corporation. Решение НАСА означает, что теперь многие европейские компании получают шанс на поставку оборудования и ракетной техники этой корпорации.
Основным узлом корабля, в изготовлении которого примут участие европейские производители, станет новый международный стыковочный механизм, который был разработан в Европе.

Корабль Dream Chaser будет иметь такой узел в его хвостовой части, с помощью которого он сможет состыковываться с МКС.
Этот узел позволяет герметизировать вход в корабль членами экипажа станции и его разгрузку.
Изготовлением этого механизма занимается бельгийская компания QinetiQ. Решение НАСА приведет к заключению многомиллионных контрактов между нею и ЕКА.
Эта компания возглавит создаваемый консорциум по производству первого такого стыковочного узла, прототип которого будет передан американской компании SNC для полетных испытаний бесплатно.
Однако дальнейшие поставки таких механизмов будут производиться на коммерческой основе.

Складные крылья
ЕКА и Германское космическое агентство DLR еще в начале 2014 года подписали с компанией SNC меморандум о взаимопонимании, в котором корабль Dream Chaser назывался в качестве возможного средства доставки грузов и людей на борт МКС.
Тогдашний глава ГКА Ян Вернер говорил об интересе европейских производителей к использованию в качестве носителя при запуске корабля тяжелой европейской ракеты "Ариан".
Однако он связал тогда эту возможность с изменением конструкции корабля - для того, чтобы поместиться под головным обтекателем ракеты "Ариан", корабль Dream Chaser должен иметь складывающиеся крылья.
Компания SNC согласилась с этим требованием при разработке грузовой версии корабля. Ян Вернер, который с тех пор стал генеральным директором ЕКА, подтвердил свой интерес к использованию этого корабля для различных космических миссий в будущем.
ЕКА проявляет особый интерес к решению проблемы космического мусора, разрабатывая методы удаления старой и нефункционирующей техники с орбиты. По мнению Вернера, корабль Dream Chaser может сыграть при этом важную роль, доставляя на орбиту роботов и мощные лазеры, которые будут использоваться при утилизации космического мусора.
Решение НАСА об использовании корабля Dream Chaser добавляет уже второй корабль многократного использования к числу средств доставки на борт МКС.
Планируется, что этот корабль сможет совершать спуск с орбиты с использованием аэродинамического планирования в пилотируемом или беспилотном вариантах. Наиболее вероятным местом посадки является посадочная полоса в космическом центре Кеннеди во Флориде.
После такой посадки корабль можно будет быстро доставлять к месту старта и устанавливать в верхней части ракеты-носителя со сложенными крыльями.
Корабль "Дракон" компании SpaceX также рассчитан на многократное использование, однако пока НАСА настаивает на использовании при каждом запуске нового корабля.

Sierra Nevada will offer two Dream Chaser mission profiles, with the option of docking or berthing to the station. Dream Chaser will launch from Cape Canaveral atop a ULA Atlas-V, with a folding wing design that will allow the spacecraft to fit inside a standard 5-meter payload fairing. It will be able to deliver up to 5,500 kg of cargo to the ISS and land with a load of 1,750 kg. Dream Chaser will offer the unique capability of providing a low-g reentry profile and a soft runway landing that would protect more delicate experiments.
While Dream Chaser will be capable of landing at civilian airports with runways 8,000 feet or longer, it will land back at Kennedy Space Center's Shuttle Landing Facility, close to facilities wh ere the spacecraft will be processed and launched. Dream Chaser will give NASA the ability to return experiments from space in 3-6 hours, a capability that hasn't existed since the space shuttle. Because Dream Chaser uses non-toxic nitrous oxide and propane propellants, experiments and cargo can be safely accessed immediately after landing. This is essential for certain biological experiments involving living organisms, tissues, and viruses, which can quickly adapt to Earth's gravity upon return.
"SNC is honored to be sel ected by NASA for this critical U.S. program," said Eren Ozmen, president of Sierra Nevada Corporation. "In such a major competition, we are truly humbled by the show of confidence in SNC and look forward to successfully demonstrating the extensive capabilities of the Dream Chaser spacecraft to the world. While Dream Chaser is still undergoing development and testing, the company is committed to achieving its first launch in 2018, well before the CRS-2 contract begins."

One of the significant upgrades is that the test article will conduct its flight test(s) with orbital avionics software this time, the same which the autonomous Dream Chaser CRS-2 cargo variant will use on its missions to and from the ISS. In doing so, SNC will earn direct certification credit out of the upcoming flight test series from NASA, therefore eliminating the need for an orbital flight test before operational CRS-2 missions.
Dream Chaser development will follow the example of Space Shuttle Columbia, STS-1. All the testing and certifications will happen on the ground and within the atmosphere, the first Dream Chaser launch will be an operational mission for NASA under the CRS-2 contract to the ISS. SNC will benefit from 135 shuttle flights & modern testing techniques to ready Dream Chaser for that first mission, and the company says Dream Chaser will be ready for that flight atop a ULA Atlas-V rocket from Cape Canaveral, Fla. in the first half of 2019.
NASA does not require a first orbital flight test for the Dream Chaser cargo version before its first operational CRS-2 flight.
SNC and NASA will be working together over the coming weeks and months to determine launch dates for their CRS-2 flights.
...
Once back on the ground the vehicle will go back to the O&C, get looked over, and be readied for its next flight. Turnaround time between landing and next launch would be around 60 days, however there are a lot of other factors that go into turnaround times, such as whether or not the rocket is even ready. The Dream Chaser itself, noted SNC, could be turned around in much less than 60 days, implying a flight rate annually of 4-6 missions per vehicle.
...
If NASA opens up another round of Commercial Crew contracts in 2020, SNC will put in a bid for their crew-version Dream Chaser.
Once the cargo-version establishes itself as a dependable, reusable, and cost-effective space system SNC expects demand for the crewed-version to increase, taking lessons learned from the cargo-version and applying them to the crew. The six missions SNC is guaranteed fr om NASA under CRS-2 is also enough funding to keep the cargo-version ready to fly for other customers if needed, according to SNC.

Куда ближе к HL-20, чем к Х-24А, если уж на то пошло. У них там куча всяких поделок было на тему несущего корпуса.

Но "советское прошлое" тоже нельзя сбрасывать со счетов. Про БОР-4 давно уже проскакивало от самих разработчиков или откуда-то около. Я даже совсем не удивлюсь, если окажется, что г-н Лукашевич в свое время продал этим ребятам всю доступную ему массу документации по БОРам из архивов Молнии.

После подписания этого соглашения ЕКА начнет работу над строительством первой летной модели стыковочного механизма International Berthing and Docking Mechanism (IBDM), который грузовая система космического корабля Dream Chaser будет использовать при осуществлении стыковки с космической станцией.

ЕКА сообщило, что готово потратить 33 миллиона евро (36 миллионов USD) на завершение разработки конструкции системы IBDM и строительство летной модели для первого запуска космолета Dream Chaser с грузом к МКС. Разработку и строительство последующих версий систем IBDM будет финансировать уже сама компания Sierra Nevada, сообщило ЕКА.

Ранее ЕКА и Sierra Nevada заключили договор, в рамках которого была начата адаптация системы IBDM к модели космического корабля Dream Chaser, однако работа в этом направлении заметно замедлилась после того, как компания Sierra Nevada не смогла выиграть тендер НАСА на поставку грузов к МКС. ЕКА к этому времени уже потратило свыше 20 миллионов евро в общей сложности на разработку этого проекта. Однако теперь неожиданная победа компании Sierra Nevada во втором раунде конкурса, подразумевающая контракт на осуществление шести миссий по доставке грузов к МКС до 2024 г. вдохнула новую жизнь в это соглашение.

Sierra Nevada Corp. moves ahead on NASA milestones for Dream Chaser spaceship
BY ALAN BOYLE (http://www.geekwire.com/author/alanboyle/) on June 22, 2016
...
Sirangelo said the Dream Chaser project had to be put on hold.
"It was a devastating loss for us," Sirangelo said. "Lots of people went away. We had to lay off people. It was very hard. ... The 90 people who were left on this program came to me and said, 'We're not ready to hang it up. We want to try again.'"

Winning the cargo development contract opened the way to resume work on the Dream Chaser. Sirangelo said his "Dream Team" is now making good progress on the retooled prototype, which is designed for atmospheric testing rather than spaceflight. Sirangelo compared the craft to the shuttle Enterprise, which NASA built in the 1970s to test the aerodynamics for the space-ready shuttles that would follow.

"Our version of the shuttle Enterprise is about to be finished for its next phase of flight tests," Sirangelo said. "Somewhere in the August time frame, it's going to be shipped off to California, to the Armstrong [Flight Research] Center and to Edwards to be in Phase 2 of flight testing, which is going to be really fun and exciting."
Sirangelo said lessons learned from the atmospheric flight tests will be applied to the development of the orbital test vehicle, which is now being outfitted in Colorado. That test vehicle, in turn, will blaze the trail for the spacecraft that will carry cargo for NASA under the CRS-2 contract.

"We are looking to be launching on time, which is about three years from now, in the second half of 2019," Sirangelo said. "That contract will go well into the next decade, so we need lots of help. We're going to be hiring lots of people. If any of you guys want to come out and work on the next space shuttle, I think it's a pretty good time to do that."

RELEASE: Sierra Nevada Corporation Completes First Dream Chaser®Cargo 
Service Milestone under NASA CRS2 Contract
SPARKS, Nev. (July 11, 2016) – Sierra Nevada Corporation (SNC) (http://www.sncorp.com/) is pleased to announce the successful completion of ISS Integration Certification Milestone 1 for the Dream Chaser (http://www.sncspace.com/ProductLines/SpaceExplorationSystems) Cargo System under NASA's Commercial Resupply Services 2 (CRS2) contract. Under this milestone, NASA approved SNC's complete program implementation plan for the design, development, test and evaluation of the Dream Chaser Cargo System. This includes plans and processes for meeting technical performance and CRS2 integration schedules associated with execution of docking and berthing missions to the International Space Station (ISS). Details included supplier plans, integration schedules, organizational structure and status of program risks and risk mitigations. Under the CRS2 contract, Dream Chaser will provide a minimum of six cargo delivery services to and from the ISS between 2019 and 2024.
More Than a Milestone
"The accelerated completion of the first milestone under the CRS2 contract award marks significant progress for SNC and the Dream Chaser program", said Mark N. Sirangelo (http://www.sncspace.com/AboutUs/MarkSirangelo), corporate vice president of SNC's Space Systems business area. "We are thankful for the support we've received from NASA. The prompt completion of this essential program milestone is a big step in bringing us closer to returning a winged, runway-landing vehicle to space. This momentum will carry us with confidence in developing a reliable and affordable solution for ISS cargo delivery, return and disposal."
In addition to SNC internal program integration, the milestone review covers the strategic plan for the involvement of external entities including international agreements and plans for obtaining necessary licenses from U.S. agencies, including the Federal Communications Commission and Federal Aviation Administration.
Flight Testing Continues
In parallel with the continued execution of CRS2 milestones, SNC plans to resume the next phase of flight testing for Dream Chaser later this year. This vehicle was originally developed and tested in partnership with NASA's Commercial Crew Program through Space Act Agreements (SAA). It was previously flown at NASA's Armstrong Flight Research Center and is being prepared for its second flight test through the SAA. It has been significantly upgraded in multiple areas to allow for testing to advance and verify critical systems which will also be used in the next generation vehicle currently under development for the forthcoming NASA ISS cargo resupply missions.

Sierra Nevada Corporation Passes Second Milestone – 

Dream Chaser® Spacecraft on Track to Supply Cargo to ISS

SPARKS, Nev. (July 25, 2016) – Sierra Nevada Corporation (SNC) (http://www.sncorp.com/AboutUs/NewsDetails/file%3A///C%3A%5CUsers%5Ceh3892%5CAppData%5CLocal%5CTemp%5Cnotes90C43B%5Csncorp.com) has passed the second Integration Certification Milestone under NASA's Commercial Resupply Services 2 (CRS-2) contract. NASA assessed and fully approved SNC's detailed approach for getting the Dream Chaser (http://www.sncspace.com/ProductLines/SpaceExplorationSystems) Cargo System to the International Space Station (ISS). SNC's approved strategy demonstrates a thorough understanding of design requirements and available resources on both a system and subsystem level.  Dream Chaser will provide a minimum of six cargo delivery missions to and from the ISS between 2019 and 2024.  The first milestone (http://www.sncorp.com/AboutUs/NewsDetails/3298) was passed several weeks ago and outlined technical, logistic and schedule procedures for the program.

"Successful completion of the second Integration Certification Milestone within six weeks of the first major milestone demonstrates that the Dream Chaser team is moving at full-speed to meet NASA's cargo delivery needs," said Steve Lindsey, senior director of programs for SNC's Space Systems business area and Dream Chaser co-program manager. "We very much appreciate NASA's help and support through this milestone and those to follow. Our collective SNC/NASA team is confident in our design and strategy for the future and look forward to completing the work necessary to bring our unique cargo services solution to the ISS as rapidly as possible."

Milestone 2 Key Components
Completion of Milestone 2 means NASA and SNC collectively agree on the certification criteria used to confirm Dream Chaser designs meet CRS-2 mission requirements.  These qualification and verification plans will be utilized during future integrated design and test milestones to validate Dream Chaser Cargo System capabilities.

Dream Chaser Flight Tests Will Support CRS2 Progress
The current flight vehicle has been upgraded with several cargo system design components to support multiple test objectives - verifying the spacecraft's performance during final approach and landing, directly supporting the CRS-2 Certification Plan approved during Milestone 2.  This will ultimately accelerate development of the first orbital mission and increase confidence through flight-tested systems. The vehicle was originally developed and tested in partnership with NASA's Commercial Crew Program, which included a full-test campaign at NASA's Armstrong Flight Research Center leading up to the October 2013 approach and landing test.

ЦитироватьDream Chaser® Spacecraft to Begin Phase Two Flight Testing

SPARKS, Nev. (July 28, 2016) – Sierra Nevada Corporation's (SNC) (http://www.sncorp.com/AboutUs/NewsDetails/sncorp.com) Dream Chaser full-scale, flight test vehicle is ready for transportation to NASA's Armstrong Flight Research Center (AFRC) in California where Phase Two flight tests will be conducted in coordination with Edwards Air Force Base (AFB). Dream Chaser program (http://www.sncspace.com/ProductLines/SpaceExplorationSystems) upgrades and initial hardware testing were completed at the Louisville, Colorado spacecraft assembly facility, and within the next several weeks the same Dream Chaser vehicle that conducted Phase One flight testing will arrive at NASA's AFRC. Upon arrival, SNC will begin a series of pre-flight ground evaluations to verify and validate the vehicle's system and subsystem designs. After successful completion of all ground testing, Dream Chaser will begin its Phase Two free-flight testing. These activities are being conducted through a Space Act Agreement with NASA's Commercial Crew Program (CCP).
"Dream Chaser continues to make strong progress toward orbital flight," said Mark N. Sirangelo (http://www.sncspace.com/AboutUs/MarkSirangelo), corporate vice president of SNC's Space Systems business area. "In addition to Phase Two flight testing, our on-time completion of the first two milestones (http://www.sncorp.com/AboutUs/NewsDetails/3426) under NASA's Commercial Resupply Services 2 (CRS-2) contract in the last two months positions us well to be on-schedule for orbital operational flight. We are very grateful for all the support we have received from NASA and the U.S. Air Force, and are excited to continue the legacy of historic flight testing that is the hallmark of NASA AFRC and Edwards AFB."

What Are We Testing?
 The vehicle will undergo a series of tests building on those performed in Phase One, including tow-tests, pre-flight tests and ending with free-flight testing. SNC is also performing additional critical tests to validate the Dream Chaser's orbital flight software and calculate the spacecraft's handling and performance characteristics. Along with other pre-flight and post-flight evaluations, this data will be used to confirm Dream Chaser's subsonic aerodynamic properties as well as flight software and control system performance requirements.
"These tests are significant for us in multiple ways; building on our previous flight test, completing a significant milestone under our CCP agreement, as well as gathering crucial data that will help complete the design of the vehicle being built for our CRS-2 contract," said Sirangelo.

CCP Testing Supports CRS-2 Development
 The Phase Two flight test efforts will be highly supportive of, and executed in parallel with continued work being done by SNC under the NASA CRS-2 program. The Dream Chaser test vehicle has been upgraded to include several hardware and software components being integrated into the Dream Chaser Cargo System design for the CRS-2 program, allowing for actual flight testing of the new components. The flight tests will act as a bridge between previous work with CCP and the next-generation vehicle currently under development for the forthcoming International Space Station cargo resupply missions.

 Sierra Nevada lifts curtain on Dream Chaser space-cargo taxi

PUBLISHED: July 28, 2016 at 7:56 pm 

Sierra Nevada Corp.'s Louisville-based Space Systems unveiled a model of its Dream Chaser spacecraft, which will be ready to ship cargo to and fr om NASA's International Space Station by the end of 2019.

The craft showed off Thursday, though, won't actually get time in space. Instead, it will be shipped to California in the next several weeks to undergo a series of atmospheric and software tests.

The company will take the results from the tests to help create the actual craft, which will be assembled in Colorado.

Although the craft was designed to carry cargo, its development really is about inspiring the next generation of space exploration, said Mark Sirangelo, Sierra Nevada's vice president of space systems.

"If we can bring the space program to all the people in America, wouldn't that be a really cool thing," Sirangelo said.

The craft, which the company is boasting as the replacement to the space shuttle, is surprisingly small — for a space craft, at least. It's 30-feet long and about 25-feet wide.

"When I first saw Dream Chaser, I was like, 'Oh my gosh, it's so small,' " company spokeswoman Mary Serafin said.

A roughly 12-foot long cargo module attaches to the back of Dream Chaser and can carry 60 percent of the scientific instruments, food, medicine or whatever else the space station needs, Sirangelo said. The other 40 percent of the supplies will be carried in Dream Chaser. Combined, the craft and module can carry 5,000 kg, he said.

It will take about 11 minutes for Dream Chaser to enter orbit, and after a few maneuvers the craft can dock with the space station wh ere it can stay for anywhere between a week to several months, program manager Steve Lindsey said.

Only Dream Chaser will return to earth, though. The module is designed to burn up in space once it's used. After it lands on earth, the craft needs 60 days until it's ready to go up again.

The autonomous space craft can handle a minimum of 15 missions to the space station, Sirangelo said. SNC won a multi-million dollar contract with NASA in January (http://www.denverpost.com/2016/01/14/sierra-nevada-space-gets-piece-of-space-station-resupply-contract/) for a minimum of six missions until 2024.

Sirangelo described Dream Chaser like an airline. NASA bought a ticket for six trips, but other companies could potentially book a flight, too. Although, those other potential ticket holders would have to be scientists or companies as the Dream Chaser is not for space tourism.

The space craft was designed for both efficiency and low costs. The bottom, nose and wings were kept black because, Sirangelo said, paint can add hundreds of pounds. Without it, Dream Chaser can carry more cargo.

Although the shuttle will be ready by the end of 2019, Sirangelo said the company isn't sure when it will actually fly. That depends on when the space station needs supplies.

SNC said it would not publicly release how much the project costs, but said the company has invested hundreds of millions alongside their multi-million dollar NASA contract.

"As the company invests, the government invests," Sirangelo said, noting that money comes only when the company meets milestones so the project is not weighing down tax payers. "We believe we're well on track to deliver."

The project currently employs about 100 people, but that will expand to anywhere between 400 and 600 people by the time it's finished. Sirangelo said Colorado 's space industry has grown in the past decade, now employing more than 150,000 aerospace workers.

SNC has been working on the Dream Chaser for 11 years and have been talking with NASA for five of them. The company was vying for a contract to shuttle people to the space station, eventually losing out to Boeing Co. and SpaceX (http://www.denverpost.com/2014/09/16/louisvilles-sierra-nevada-space-left-out-of-nasa-space-taxi-contract/). The company protested, but its attempts were unsuccessful (http://www.denverpost.com/2014/09/26/sierra-nevada-protests-to-gao-over-loss-of-nasa-space-taxi-contract/).

Соответственно и многоразовость у него другая выходит...

Площадь шита больше, тормозить эффективней он начнет в более высоких слоях атмосферы.. Почему должны быть сильнее перегрузки? А в нижних слоях более пологая траектория растянет время торможения и опять же снизит перегрузки.

Sierra Nevada Corporation and the United Nations Announce First-Ever Dedicated United Nations-Dream Chaser® Space Mission

Launching a Dedicated Dream Chaser Microgravity Mission for Member States in 2021

SPARKS, Nev. (September 27, 2016) – Sierra Nevada Corporation  (http://www.sncorp.com/)(SNC)  and the United Nations Office of Outer Space Affairs (http://www.unoosa.org/) (UNOOSA) and have announced details of the first-ever United Nations space mission at the International Astronautical Congress  today in Guadalajara, Mexico. The dedicated Dream Chaser® Mission is targeted at providing developing countries the opportunity to develop and fly microgravity payloads for an extended duration in orbit; however, all United Nations Member States will be able to propose payloads for the mission.Innovating for Positive Impact
"At SNC our goal is to pay it forward," said Eren Ozmen (http://www.sncorp.com/AboutUs/ErenOzmen), SNC's owner and president. "That means leveraging the creation and success of our Dream Chaser spacecraft to benefit future generations of innovators like us all around the world."This announcement builds on the Memorandum of Understanding (MOU) signed in June 2016 (http://www.sncspace.com/AboutUs/NewsDetails/3267) between UNOOSA and SNC to collaborate on this historic United Nations space mission. The first-ever United Nations space mission is intended to launch in 2021 and will allow United Nations Member States to participate in a 14-day flight to low-Earth orbit (LEO) on SNC's Dream Chaser spacecraft."One of UNOOSA's core responsibilities is to promote international cooperation in the peaceful use of outer space," said Simonetta Di Pippo, director of UNOOSA. "I am proud to say that one of the ways UNOOSA will achieve this, in cooperation with our partner SNC, is by dedicating an entire microgravity mission to United Nations Member States, many of which do not have the infrastructure or financial backing to have a standalone space program."Making Space Affordable
According to Ms. Di Pippo, funding of the mission will come from multiple sources.  "We will continue to work closely with SNC to define the parameters of this mission which, in turn, will provide United Nations Member States with the ability to access space in a cost-effective and collaborative manner within a few short years. The possibilities are endless."Countries sel ected to provide mission payloads will be asked to pay a pro-rated portion of the mission cost, based on the resources required to host the payload and their ability to pay.  In addition, major sponsors are being sought to finance a large portion of the mission costs.Path to Mission Launch
Over the next year, mission partners will conduct briefings to United Nations Member States and potential payload providers about the goals and framework of the mission and to solicit proposals for payloads.  To make the program more accessible to nations without a highly developed space industry, UNOOSA will offer technical support to countries that lack expertise or experience in developing microgravity payloads. Payloads will be selected in early 2018 to allow time for development and integration into the Dream Chaser spacecraft for launch expected in 2021. SNC's Dream Chaser (http://www.sncspace.com/ProductLines/AboutDreamchaser) is the only reusable, lifting-body, multi-mission-spacecraft capable of landing at commercial airports or spaceports able to accommodate large commercial aircraft – anywhere in the world. This offers the opportunity to land the United Nations mission in any licensed Member State supplying a payload on the mission. SNC is currently working with airports and spaceports to be granted a Federal Aviation Administration reentry license for  commercial Dream Chaser missions. Recently selected to provide cargo delivery, return and disposal services for the International Space Station (ISS) under NASA's Commercial Resupply Services 2 (CRS-2) contract, Dream Chaser is a safe, affordable, flexible and reliable system capable of crewed and uncrewed transportation services to LEO destinations such as the ISS.

THE DREAM CHASER® FOR EUROPEAN UTILIZATION PROGRAM TAKES FLIGHT WITH MEMORANDUM OF UNDERSTANDING
 
SPARKS, Nev. (October 11, 2016) - The Dream Chaser® (http://www.sncorp.com/what-we-do/dream-chaser-space-vehicle.html) for European Utilization (DC4EU) program kicked off its pilot phase with the signing of a Memorandum of Understanding (MOU). Sierra Nevada Corporation (http://www.sncorp.com/index.html) (SNC), Telespazio, the European Space Agency (ESA) and OHB System AG (OHB) will now assess the feasibility and commercial viability of the DC4EU dedicated mission to provide affordable, independent European access to low-Earth orbit (LEO) via the Dream Chaser space utility vehicle (SUV).

"The Dream Chaser SUV is the only reusable, lifting-body spacecraft with a commercial runway landing capability anywhere in the world – offering safe, affordable, flexible and reliable transportation to space," said Mark Sirangelo, (http://www.sncorp.com/who-we-are/mark-sirangelo.html) corporate vice president of SNC's space systems business area. "That is exactly what our industry team is offering Europe during the ISS transition phase."
 
The DC4EU Pilot Phase
The DC4EU mission was one of eight sel ected by ESA to begin pilot phase implementation in 2016. It offers the best value for European access to LEO by providing a full end-to-end mission capability using the unique attributes of the SUV including, compatibility with the European Ariane 6 launch vehicle and the ability to land on suitable runways for near-immediate payload access. The objective of the pilot phase is to demonstrate the technical and programmatic feasibility of DC4EU, which includes the preparation of a business plan highlighting the partnership viability for both private and public interests.

"Commercial partnerships are a new element of the ESA Space Exploration Program. They open up space exploration for private sector-led initiatives and offer exciting opportunities for advancing the implementation of the ESA strategic goals for space exploration in novel ways and for enlarging the stakeholder community actively engaged in exploring space," said David Parker, ESA director for Human Spaceflight and Robotic Exploration.
Dr. Fritz Merkle (http://www.ohb.de/press-releases-details/dr-fritz-merkle-appointed-to-the-management-board-of-ohb-ag.html), Chief Marketing Officer and Executive Board Member of OHB Group highlighted another key use for future missions, "One national and international mission goal is a sustained utilization of human-tended infrastructures beyond the life of the International Space Station (ISS) with increased cost efficiency and responsiveness to utilization interests."

Giuseppe Aridon, Vice President Strategy and Marketing of Telespazio explains: "DC4EU could represent a valuable platform to enable independent European access to LEO through a 'customized' European variant of the Dream Chaser spacecraft. We are willing to explore the potential of such a promising solution, that could be a major element for the setting up of the future European LEO service missions ecosystem, that will see the Dream Chaser operating alongside other European assets and infrastructures for first of a kind transatlantic partnership in this field, with true a global perspective!"
 
DC4EU Team
In March 2015, ESA released a Call for Ideas (CFI) for ‎strategic partnerships with the private sector in the field of Space Exploration. In response, OHB System AG (https://www.ohb-system.de/) (Germany), Sierra Nevada Corporation (http://www.sncorp.com/index.html) ‎‎(USA) and Telespazio (http://www.telespazio.com/) SpA (Italy) teamed to create what is now called  Dream Chaser for European ‎Utilization (DC4EU). ESA has sel ected the DC4EU mission out of 60 partnership ideas for a pilot phase implementation. Developed by SNC, the Dream Chaser SUV is contracted by NASA to provide cargo services to and from the ISS under the Commercial Resupply Services 2 (CRS2) contract. The uncrewed Dream Chaser spacecraft variant is capable of transporting pressurized and unpressurized cargo to and from LEO with controlled entry and landing on approved airports.

Dream Chaser: The Spacecraft That Will Transform Humanity's Access to Space
The United Nations is set to launch a revolutionary global space program
By Robin Seemangal • 10/03/16 3:44pm
....
To learn about the Dream Chaser's development and the possibilities that will emerge because of the UN's partnership with SNC, the Observer sat down with, Mark Sirangelo, the Colorado-based company's Vice President and the pioneer behind this groundbreaking project.
...

What is the process to become qualified?

They have to go through the FAA, it's like qualifying to be an airport. Interesting enough, two have gone through most of the process. One is in Houston, Texas and the other is in Huntsville, Alabama—a commercial airport. We realized that we've got something special because we're the only vehicle that can do this.

That's when we began looking beyond NASA to see what else we could do with the Dream Chaser. We asked ourselves, what can we do for business? And what can we do for the good of humanity? So we started looking at ways for providing the vehicle.

NASA or the US Government does not own the vehicle, so we can do other things with it. We could contract it out to other countries who would like to have a space program, other space agencies, companies that may want to do manufacturing in space. So one of the ideas we came up with to show how Dream Chaser could do good for the world was our new partnership with the United Nations Office for Outer Space Affairs.
.....

What other ways could a nation benefit from utilizing this program?

When people send experiments to space, they don't usually come home. Just the data does. And that's because there isn't a vehicle with the ability to do that. Dream Chaser would come home with the scientific hardware it takes up. This means that countries that invest in their experiments would be able to retrieve it and be able to update or fix it and we can fly it again. It's a very unique concept. Plus, landing anywhere in the world could be a big deal for a developing nation—to have scientific experiments from space land in your home country.

SP-4220 Wingless Flight: The Lifting Body Story
...
Lifting-Body Concept Goes International

The NASA lifting-body program has been well documented in about 100 technical reports on the program's 222 flights and 20,000 hours of wind-tunnel tests. Many of these publications are unclassified. The Soviet Union purchased copies of these reports from NASA Headquarters in Washington, D.C., then designed its own lifting body. In 1982, the Soviets flight-tested an unpiloted, 10-foot-long, subscale version of their lifting body, the BOR-4, including a maneuvering re-entry over the Indian Ocean from space orbit. The flight test of the BOR-4 closely resembled that of our PRIME (X-23) vehicle in 1966. The main difference between the two was that the BOR-4 was parachuted into the Indian Ocean for ship recovery, while the PRIME had been snatched from the air by a C-130 to avoid a splash down in the Pacific Ocean. There is no information available yet on whether the successor states of the former Soviet Union continued their work in the 1980s into larger-scale lifting bodies.

Спойлер

Other than the Soviet flight experiments with the BOR-4, very little lifting-body design activity seems to have occurred in the 1980s. In the United States, the Shuttle satisfied all requirements for space flight. Even though the Soviets had built a copy of [181] our Shuttle, they flew it only once (unpiloted) and continued to rely on parachute recovery for their spacecraft.

As the concept of an International Space Station emerged in the United States and other countries, however, interest revived in lifting-body configurations. Countries involved in or entering space exploration accepted that the International Space Station was required if mankind were to maintain a presence in space in preparing to send human beings to Mars and other planets or to revisit the moon. Smaller vehicles costing less to operate would be needed over many decades for the International Space Station. The small, compact shapes of lifting-body configurations began to show up on engineering sketch pads and drawing boards for use as space ferries or emergency lifeboats.

Other countries entering the realm of space technology have also demonstrated interest in lifting bodies for various projected space missions. For example, the Japanese conducted hypersonic re-entry flight tests with parachute recovery during February 1997 of the HYFLEX, an unpiloted lifting body. The French also have indicated that they are doing mission studies using lifting bodies.

HL-20 Lifting-Body Space Ferry

During 1990-1995, NASA Langley conducted studies on a new lifting-body shape designated the HL-20, designed to meet the projected need for a low-cost transportation system to ferry personnel between Earth and future space stations. As part of the NASA Langley study, personnel at North Carolina Agricultural and Technical University and North Carolina State University built a full-scale mockup of the HL-20 in 1990.

Designed to carry ten people into orbit and back, the HL-20 would be considerably smaller and lighter than the present Shuttle, the large size of the Shuttle being unnecessary for many of these future missions involved with transporting personnel to and from space stations and with delivering supplies to space stations. The projected HL-20 would be only 31 feet long and weigh 32,448 pounds, considerably smaller and lighter than the Shuttle, which is about 122 feet long and weighs over 171,000 pounds without its propellants, external tank, and solid rocket boosters. The HL-20 would be boosted into orbit by a Titan III rocket system, a system smaller than the Shuttle's rocket system.

Dream Chaser Spacecraft Arrives at NASA Armstrong

Sierra Nevada Corporation delivered its Dream Chaser spacecraft Wednesday to NASA's Armstrong Flight Research Center in California, located on Edwards Air Force Base. The spacecraft will undergo several months of testing at the center in preparation for its approach and landing flight on the base's 22L runway.

The test series is part of a developmental space act agreement SNC has with NASA's Commercial Crew Program (https://www.nasa.gov/commercialcrew). The upcoming test campaign will help SNC validate the aerodynamic properties, flight software and control system performance of the Dream Chaser.

The Dream Chaser is also being prepared to deliver cargo to the International Space Station under NASA's Commercial Resupply Services 2 (CRS2) contract beginning in 2019. The data that SNC gathers from this test campaign will help influence and inform the final design of the cargo Dream Chaser, which will fly at least six cargo delivery missions to and from the space station by 2024.

Dream Chaser spacecraft joins Boulder County morning commuter traffic
By Charlie Brennan
Staff Writer

01/20/2017

Morning commuters in Boulder and Longmont on Friday found themselves sharing the road with an oversized vehicle that appeared more appropriate for the airspace above them.
A spokeswoman for Louisville's Sierra Nevada Corporation confirmed that its Dream Chaser spacecraft has been "wrapped up" and was being transported to an undisclosed location for testing.
Motorists might well have seen the spacecraft, on a truck with police escort, on Arapahoe Road, Foothills Parkway or the Diagonal Highway before it headed east on Colo. 119 toward Interstate 25.
Sierra Nevada communications manager Kimberly Schwandt said Friday that she had no more details to provide about its destination.
Sierra Nevada's Dream Chaser spacecraft is a multi-mission, commercial, lifting-body vehicle capable of transporting services to low-Earth orbit destinations, including the International Space Station. Officials have said that payloads will be selected in early 2018 to allow time for development and integration into the Dream Chaser for expected launch in 2021.

Officials Mull Proposal for Manned Mission to Refurbish Hubble Telescope

Industry initiative could meet Trump goals of swift, dramatic space effort.
....
Years ago NASA officials considered, on their own, a similar mission using basically the same spacecraft to link up with the 6-ton Hubble, circling the Earth roughly every 90 minutes at an altitude of more than 300 miles. But no formal program was developed or funded by Congress.

For Sierra Nevada, such a task would be a natural extension of its drive to find multiple uses for the Dream Chaser. It can be used "as an exploration vehicle, a free-flight science laboratory and a servicing vehicle" for in-orbit satellites and spacecraft, Mark Sirangelo, head of the company's space systems unit, told a conference in Washington last week. The spacecraft, which isn't due for its inaugural unmanned launch until 2019, also is intended to be capable of landing on any conventional runway long enough to handle a Boeing (http://quotes.wsj.com/BA) Co. 737 jetliner.

Over the weekend, a company representative said a Hubble mission would allow valuable research to continue and "inspire new generations of explorers and researchers." He said that Dream Chaser was "designed from the beginning to be a multi-mission orbital transportation system" eventually targeting "servicing, repair and assembly of technology" during space flight. "They have always been part of our vision," he said, and Sierra Nevada "continues to actively evaluate a future on-orbit servicing variant."

In little more than a decade, Sierra Nevada has grown from a handful of employees to a company with a workforce of 2,000 and operations in 19 states. It manufactures small satellites, electronic systems, an array of spacecraft components and does considerable business with NASA.

Replacing navigation hardware, aging sensors and other geriatric parts on Hubble would require relatively few additional dollars, because the telescope has a modular design and Dream Chaser's cargo variant already is undergoing flight tests. The vehicle would need additional life-support systems as well as a launch-abort system designed to protect the crew in the event of an explosion or serious problem on the pad or during early phases of its ascent.

Sierra Nevada previously designed both systems in detail, though additional resources would be needed to conduct further tests and build flight hardware.

[свернуть]

An atmospheric test model of Sierra Nevada's Dream Chaser space plane is being readied for tow and landing tests at NASA's Armstrong Flight Research Center in California this spring.

The partially-assembled test craft arrived at the California test site, located on Edwards Air Force Base, on Jan. 25. Technicians are adding the ship's V-shaped tail fins and other equipment before kicking off ground and flight tests in the coming months, according to Mark Sirangelo, corporate vice president of Sierra Nevada's space systems division.

Спойлер

"We'll do a series of ground tests," Sirangelo said in a recent interview. "That will include towing the vehicle down the runway, and that allows us to see how it stops and how it moves, but it also allows us to test all the sensors on the vehicle because we can get it up to a high enough speed where that will happen."

The Dream Chaser spacecraft, originally envisioned to fly with astronaut crews, will now fly on space missions with cargo deliveries heading for the International Space Station. That change means the spaceship will return to Earth on autopilot, using navigation aids to descend to a runway, deploy its landing gear and touch down like NASA's space shuttles.

After the ground tests, Sirangelo said the Dream Chaser test article will perform "captive carry" tests suspended under a helicopter, using the exercises to verify the movements of the craft's aerosurfaces and navigation instrumentation.

"When that's done, we'll move into a series of flight tests, where it will be dropped for approach and landing like the shuttle Enterprise," Sirangelo said, referring to the vehicle NASA used for landing demonstrations in the 1970s before the first full-up space shuttle mission.

The Dream Chaser will be dropped from heavy-duty carrier helicopter for an autonomous landing at Runway 22L at Edwards Air Force Base.

The test campaign in California's Mojave Desert comes three-and-a-half years after Sierra Nevada's Dream Chaser last flew on its own. A drop test in October 2013 ended with a crash landing after the ship's left landing gear failed to deploy.

Sierra Nevada says the 2013 flight was successful until that point, and Dream Chaser's autopilot landing system steered the craft toward the runway for a touchdown on the centerline.

Engineers blamed the mishap on a landing gear borrowed from a U.S. Air Force F-5E jet. Future Dream Chaser cargo missions to the space station will fly with a different landing gear, and the spaceship preparing for tests this spring in California features a gear more advanced then the suspect system at fault in 2013.

"We had borrowed that gear for that test, and that was one of the decision we made that didn't work out, obviously," Sirangelo said. "It wasn't the orbital flight design. It's a completely different design system now, so it's very different from what we had before. It's not quite the full orbital design, but it's on that path."

After the crash landing in 2013, Sierra Nevada returned the damaged test craft to the company's facility in Louisville, Colorado, for repairs. While the vehicle set for landing tests in the coming months is the same one that flew in 2013, Sirangelo said it is "substantially upgraded."

"It's much more close to the (configuration) of the orbital vehicle now, with flight software," Sirangelo told Spaceflight Now. "It's fully autonomous, so it will use flight software that we'll go to orbit with. All the control surfaces, and all the data gathering is all electronic.

"The computer systems are now the orbital version of the computer systems that we will manage with, so it's structurally similar, but virtually the whole inside of the vehicle has been updated and changed."

In 2013, Sierra Nevada was competing with Boeing and SpaceX for lucrative contracts with NASA to carry astronauts to and from the International Space Station. The space agency awarded the crew transportation deals to the other two companies in 2014, leaving Dream Chaser's future uncertain.

But Sierra Nevada found other business for the lifting body space plane, primarily in the space station's cargo resupply program. NASA announced in January 2016 that Sierra Nevada, SpaceX and Orbital ATK will be responsible for hauling up most of the space station's U.S. cargo and experiments from 2019 through 2024, the station's current planned retirement date.

SpaceX and Orbital ATK are the incumbent commercial cargo transportation contractors, and Sierra Nevada will join them in the follow-on contract.

Sierra Nevada also has agreements with the European Space Agency to study the use of Dream Chaser to provide access to space for European research experiments after the end of the space station program in the 2020s. The United Nations agreed last year to purchase a standalone unpiloted Dream Chaser mission to Earth orbit in 2021 to host research payloads from developing nations.

Sirangelo said the long gap between Dream Chaser flight tests was not only driven by technical concerns — like the upgrade and repair of the test craft — but by closing the business case for the program.

"We had to go and win a contract," Sirangelo said. "We needed a path to really make this all worthwhile to take this next step. Once we won the contract a year ago, we were able to accelerate the program and get back into flight tests."

The feeling among Sierra Nevada's team is different this time, he said.

"Not only are we back in flight tests, but now it's different in that we know that we have a contract," Sirangelo said. "We have flights coming up. We've got decades of flights in front of us, so it's a different feeling."

Under the structure of the cargo resupply contract, each partner must pass several programmatic, safety and integration milestones before flying missions. Sierra Nevada has passed two of those milestones so far, Sirangelo said, and a preliminary design review for the full Dream Chaser system is coming up soon.

NASA has not ordered resupply missions from any of the three providers under the new cargo contract — called Commercial Resupply Services-2 — but Sirangelo said the company hopes to get a firm order and a target launch date from the space agency this year. Each of the three CRS-2 contract winners is guaranteed at least six missions.

On space station resupply runs, the Dream Chaser will take off from Florida on top of United Launch Alliance Atlas 5 rockets and return to runway landings at one of several potential sites, such as the Shuttle Landing Facility at the Kennedy Space Center, for unpacking, refurbishment and reuse.

The Dream Chaser is about one-quarter the size of a space shuttle orbiter, allowing it to land on shorter runways.

It is capable of delivering more than 12,000 pounds (5,500 kilograms) of equipment to the space station inside its pressurized compartment and on an external aft-mounted payload carrier. At the end of each flight, the two parts will detach, with the Dream Chaser space plane returning to Earth with research specimens and other gear, and the disposable cargo module burning up in the atmosphere to incinerate trash.

The fully-loaded spacecraft will weigh around 20 tons and will likely require the lift capacity of ULA's most powerful Atlas 5 rocket configuration — the "551" with five strap-on solid rocket boosters and a 5-meter (17-foot) payload fairing, according to Sirangelo.

The first space-rated Dream Chaser is "well under design and development" and on schedule, he said.

"We've now built the full pressure shell and tested it, and now we're building the orbital shell — we call it the external structure — the structure of the vehicle, and all the flight software," Sirangelo said. "A lot of the work has been on the software side because it is a fully autonomous vehicle now, so it's well on the way to being ready on time."

Lockheed Martin built the Dream Chaser's composite structure, and Sierra Nevada will locate the spaceship's launch site processing facility alongside Lockheed Martin's Orion production line inside the Neil Armstrong Operations and Checkout Building at the Kennedy Space Center in Florida.

Learned a lot today from a talk from a Spaceflight mission manager at the IEEE Aerospace Conference. Apologies for the potato quality photo (http://m.imgur.com/a/OpVM9) - SpaceX details transcribed below:
 SSO-A - Q4 2017, 575 x 575 km SSO, 10:30 plane SSO-B - Q4 2018, 500 x 500 km SSO, 10:30 plane GTO-1 - H2 2018, 200 x 35786 km, 27.5 deg inclination GTO-2 - H2 2018, 200 x 60000 km, 27.5 deg inclination SSO-C - H2 2019, 500 x 500 km SSO, 10:30 plane GTO-C - H1 2020, 200 x 35786 km, 27.5 deg inclination (and away went consistent mission naming) SSO-D - H2 2020, 500 x 500 km SSO, 10:30 plane
 It's unclear if missions beyond SSO-A are officially under contract, though it's not unreasonable to believe that at least some of them are, given that 2-3 years is not a whole lot of lead time in rocket land. These missions are all "dedicated rideshare," meaning Spaceflight has bought (or intends to buy) the entire F9, and then sell off payload space to smaller spacecraft (SSO-A was quoted as carrying 90 satellites).
In other manifest shuffling news, SpaceIL is not flying their lunar lander with SpaceX at the end of this year as planned, due to delays on their end - they're targeting a launch in 2019 (unclear if F9 or someone else). Speaking of delays, Spaceflight manager said that he expects Formosat-5 (an F9 launch which, until recently, was to carry a ring of secondary payloads for Spaceflight on a Sherpa carrier) to launch sometime in 2017, but that Spaceflight pulled out because they were fed up with delays and had some customers who'd been delayed over 2 years, and were concerned that Formosat-5 has a low priority in the launch queue and could slip to 2018. The Sherpa payloads were remanifested to a mixture of Indian PSLV launches (some as soon as this summer) and the nominally-in-December SSO-A.

Final bonus new info from Sierra Nevada Corp, who had a speaker to talk about the Dream Chaser. In its cargo configuration (which won a CRS2 contract, and will be serving cargo missions alongside SpaceX starting around 2019), the Dream Chaser is launched inside of a fairing towing an extra pressurized cargo capsule. The capsule makes the entire Dream Chaser assembly too long to fit in a SpaceX fairing, but its wings fold, allowing it to fit cross-sectionally (indeed, she said a crew Dream Chaser could probably fly on an F9, as the crew version doesn't use a fairing or tow an extra cargo pod). The speaker said that Sierra Nevada talked to SpaceX about engineering a longer fairing (and was naturally met with "sure, if you pay for it"  ;)  but expects to look at it more seriously in a couple of years.

 Dream Chaser to use Europe's next-generation docking system
 
6 April 2017

 ESA and a team of European industrial contractors led by QinetiQ Space have finalised an agreement with Sierra Nevada Corporation for the use of Europe's International Berthing Docking Mechanism on the Dream Chaser spaceplane.

 The Sierra Nevada Corporation (SNC) Dream Chaser is being developed as a reusable, lifting-body, multimission spacecraft capable of landing at commercial airports or spaceports that can accommodate large commercial aircraft anywhere in the world.

Спойлер

Selected to provide cargo delivery, return and disposal services for the International Space Station under NASA's Commercial Resupply Services 2 contract, it is a safe, affordable, flexible and reliable system, designed to provide crewed and uncrewed transportation services to low orbit destinations, such as the Space Station and future commercial space infrastructures.    
 
  (https://img.novosti-kosmonavtiki.ru/225406.jpg)  (http://www.esa.int/ESA_Multimedia/Images/2017/04/The_International_Berthing_Docking_Mechanism)
 
 The International Berthing Docking Mechanism (IBDM) is an androgynous, contact force-sensing, low-impact docking system, capable of docking and berthing large and small vehicles.

 The IBDM consists of the Soft-Docking System and the Hard-Docking System. The first captures and actively dissipates the kinetic energy of the two spacecraft. The second makes the structural pressurised connection between the spacecraft.

 The IBDM is fully compatible with the International Docking System Standard (IDSS) defined by the Station partner agencies and with the new docking ports being made available at the Station.

 ESA developed the docking system in cooperation with NASA, with the goal of building a modern docking system for space vehicles visiting the Station after the Space Shuttle's retirement. 

 The dual active control loop markedly improves on existing technology by reducing the docking forces on the space infrastructure and by enabling the capture and docking of a wide range of spacecraft mass and flight envelopes.

 QinetiQ Space has been leading IBDM development since the beginning and it has set up an industrial team including SENER (Spain and Poland), responsible for the Hard-Docking System, Ruag AG (Switzerland) for the linear actuators, and Maxon (Switzerland) for the electric motors.
 
  (https://img.novosti-kosmonavtiki.ru/225403.jpg)  (http://www.esa.int/ESA_Multimedia/Images/2017/04/Signing_Dream_Chaser_IBDM_agreement)
 
 David Parker, ESA Director of Human Spaceflight and Robotic Exploration, notes, "This agreement is an additional step forward in international cooperation and it has a strategic value in view of ESA's current involvement and future plans for international human exploration missions, as well as for potential commercial activities and servicing scenarios in low orbit. SNC has shown interest in joining forces with Europe for a mutually beneficial cooperation."  

 "We have always envisioned the Dream Chaser to be a vehicle with global reach and have actively sought international cooperation," said Mark Sirangelo, corporate vice president of SNC's Space Systems business area. 

 "This IBDM partnership is a significant example of that. SNC is very pleased to be working with ESA and its industrial partners on this technology."
 
 Erik Masure, Managing Director at QinetiQ Space, added, "QinetiQ, and its industrial consortium, are extremely pleased with SNC's selection of the IBDM as docking system for the Dream Chaser.

 "This first host vehicle for the IBDM is a milestone in QinetiQ's plans to establish the IBDM as a product to serve a large community of host vehicles.

 "We believe that the smart design of the IBDM will be an enabling technology towards all sorts of vehicles: cargo and crewed vehicles, heavy and very lightweight vehicles, low-orbit and beyond low-orbit vehicles."

 "The IBDM project is a first case of public–private partnership within the ESA's space exploration programme," underlined David Parker.

 "Alongside the main financial contribution of the Member States, as in other ESA optional programmes, the industrial companies participating in the IBDM development are providing their own investment, aiming at the creation of a commercial product, which will be offered on the space market worldwide."

ЦитироватьDream Chaser® Spacecraft Passes Major Milestone
Completes Successful Integration Review for Space Station Resupply Mission

 SPARKS, Nev., May 25, 2017 – SPARKS, Nev. (May 25, 2017) – Sierra Nevada Corporation (SNC) successfully passed the third integration milestone for the Dream Chaser (https://www.sncorp.com/what-we-do/dream-chaser-space-vehicle/) program under the NASA Commercial Resupply Services (CRS2) program (https://www.sncorp.com/press-releases/snc-crs2-announcement/), bringing it a major step closer to providing resupply services to the International Space Station (ISS).

CRS2 Integration Review #3 (IR3) confirmed SNC's Dream Chaser Cargo System design meets NASA's key requirements and maximizes probability of mission success during future flights.  The spacecraft is scheduled for at least six missions between 2019 and 2024. The reliability of the Dream Chaser design was also thoroughly reviewed as part of NASA's Phase I Safety Review Process, which successfully demonstrated safety and mission assurance criteria.   The reviews covered all stages of mission operations including ground, launch, flight and landing.

Спойлер

"Passing the third CRS2 integration milestone is a really big deal for the program and its future," said Steve Lindsey, vice president of Space Exploration Systems for SNC's Space Systems business area. "We are proud of this accomplishment and  are well on our way towards completing the next critical milestone and the remaining developmental phases.  It's a great feeling to be executing all our milestones on schedule and to be moving forward to our operational flight."

The spacecraft's unique cargo design transports more cargo mass (5,500 kilograms) to the ISS each mission.  In addition, a significant amount of cargo, almost 2,000 kilograms is directly returned fr om the ISS to a gentle runway landing at a pinpoint location. Dream Chaser's all non-toxic systems design allows personnel to simply walk up to the vehicle after landing, providing immediate access to time-critical science as soon as the wheels stop.

The complex and thorough review process found no significant design, build or system issues and underscored the Dream Chaser's readiness for flight.

The major elements of Milestone 3 included:

[/li]
• Successful completion of the NASA Phase 1 Safety Review
• 32 Hazard Reports and 16 Safety Data Packages approved by NASA
• Dream Chaser Architectural Design's met all CRS2 requirements (hardware, software, flight dynamics, thermal control, etc.)
• More than 100 detailed design documents were delivered to NASA along with 30+ design reviews
• During the three-day IR3 review, more than 1,000 charts were briefed to the approximate 45 member NASA and Federal Aviation Administration (FAA) team, which demonstrated that Dream Chaser is at Preliminary Design Review level of maturity
• Launch vehicle operations, outside subcontracts and agreements
• Range safety plan, as well as FAA, Federal Communications Commission (FCC) and National Telecommunications and Information Administration (NTIA) licensing
• 5 Safety Review Phase 1 meetings were conducted prior to the IR3 review and involved the delivery of 46 individual Safety Data Packages developed under our S&MA team.
  

In addition to completing this milestone, the Dream Chaser atmospheric test vehicle is in preparations for flight testing that will help verify these designs. The spacecraft is currently testing at NASA's Armstrong Flight Research Center in California, having just successfully completed Phase One ground testing leading up to its second free flight test later this year.

ЦитироватьSierra Nevada's Dream Chaser on the move in California
July 17, 2017 (https://spaceflightnow.com/2017/07/) Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)
 
An atmospheric test model of Sierra Nevada's Dream Chaser spacecraft, a cargo carrier for the International Space Station that will take off on top of an Atlas 5 rocket and land on a runway, is undergoing braking and steering checks in California ahead of a flight test later this year, the company said Monday.

The full-scale Dream Chaser is pulled behind a tow vehicle for the ground tests now underway, reaching speeds fast enough to gauge the craft's braking performance and guidance, navigation and control systems.

Rolling on two main landing gear wheels and a nose skid, the Dream Chaser traveled down a runway Monday in Sierra Nevada's latest tow test at Edwards Air Force Base, which is co-located with NASA's Armstrong Flight Research Center.

Once cut free fr om its tow vehicle, the Dream Chaser slowed to a stop, allowing engineers to gather data on the craft's brakes, steering system, and guidance, navigation and control sensors that will line the spaceplane up for landing, according to Eric Cain, a Sierra Nevada engineer who described Monday's test on the company's Twitter account.

More tests are planned in the coming months, including additional tow tests and a "captive carry" flight with the Dream Chaser suspended under a helicopter.

"When that's done, we'll move into a series of flight tests, wh ere it will be dropped for approach and landing like the shuttle Enterprise," said Mark Sirangelo, corporate vice president of Sierra Nevada's space systems division, in an interview earlier this year.

Sirangelo was referring to the vehicle NASA used for landing demonstrations in the 1970s before the first full-up space shuttle mission.

The Dream Chaser will be dropped from heavy-duty carrier helicopter from an altitude of 10,200 feet (about 3,100 meters) above the ground for an autonomous landing at Runway 22L at Edwards Air Force Base.

The approach and landing test later this year will be the second time Sierra Nevada has dropped the Dream Chaser from a helicopter. A similar test using the same test vehicle in October 2013 made a smooth approach to the runway, but the Dream Chaser's left landing gear failed to deploy.

Sierra Nevada says the 2013 flight was successful until that point, and Dream Chaser's autopilot landing system steered the craft toward the runway for a touchdown on the centerline.

Engineers blamed the mishap on a landing gear borrowed from a U.S. Air Force F-5E jet. Future Dream Chaser cargo missions to the space station will fly with a different landing gear, and the refurbished spaceship now in California features a gear more advanced then the one at fault in 2013.

"It's much more close to the (configuration) of the orbital vehicle now, with flight software," Sirangelo told Spaceflight Now earlier this year. "It's fully autonomous, so it will use flight software that we'll go to orbit with. All the control surfaces, and all the data gathering is all electronic.

"The computer systems are now the orbital version of the computer systems that we will manage with, so it's structurally similar, but virtually the whole inside of the vehicle has been updated and changed."

Meanwhile, technicians are building the space-rated version of the Dream Chaser that will fly into orbit on a cargo run to the space station as soon as 2019.

The Dream Chaser is about one-quarter the length of NASA's space shuttle orbiters, and it will blast off from Cape Canaveral inside the payload fairing of United Launch Alliance Atlas 5 rockets.

It is capable of delivering more than 12,000 pounds (5,500 kilograms) of equipment to the space station inside its pressurized compartment and on an external aft-mounted payload carrier. At the end of each flight, the two parts will detach, with the Dream Chaser space plane returning to Earth with research specimens and other gear, and the disposable cargo module burning up in the atmosphere to incinerate trash.

Based on a lifting body aerodynamic design, the Dream Chaser will weigh about 20 tons fully loaded, likely requiring the lift capability of ULA's most powerful Atlas 5 configuration, the "551" with five strap-on solid rocket boosters, according to Sirangelo.

The ships returning from the space station will glide to landings at the three-mile-long Shuttle Landing Facility at NASA's Kennedy Space Center in Florida, bringing back research specimens and other hardware. Sierra Nevada plans to reuse the Dream Chaser on multiple flights.

NASA sel ected Sierra Nevada's Dream Chaser in 2016 to join SpaceX's Dragon and Orbital ATK's Cygnus supply ships in the U.S. fleet of commercial space station cargo freighters.

SpaceX and Orbital ATK currently fly resupply missions to the space station under a contract due to expire at the end of 2018. Sierra Nevada will join the incumbent contractors under a follow-on agreement that runs from 2019 through 2024, during which each company is guaranteed at least six cargo flights.

Sierra Nevada initially developed the Dream Chaser to contend for a lucrative contract to ferry astronauts to and fr om the space station, but Boeing and SpaceX won that deal. Engineers redesigned the Dream Chaser for unpiloted logistics flights after losing the commercial crew competition in 2014.

The target date for Dream Chaser's first space voyage — Sierra Nevada and NASA agreed not to conduct a standalone orbital test flight — depends on when NASA authorizes the contractor to commence mission planning.

A NASA official said last month that the agency has, so far, only ordered one space station cargo mission under the new Commercial Resupply Services-2 contract. That order went to Orbital ATK for a resupply flight in 2019, but SpaceX and Sierra Nevada are expected to receive their first CRS-2 mission authorizations in the coming months.

Sierra Nevada has passed three "integration milestones" since the 2016 cargo contract award, in which NASA and the Federal Aviation Administration reviewed design documents and safety data packages.

Sierra Nevada finalized an agreement earlier this year for the Dream Chaser to dock or berth to the space station using an attachment mechanism developed by a consortium of European companies led by QinetiQ Space of Belgium.

Centennial, Colo., (July 19, 2017) – Sierra Nevada Corporation (SNC) announced that it sel ected United Launch Alliance's (ULA's) commercially developed Atlas V rocket to launch the first two missions of its Dream Chaser cargo system in support of NASA's Cargo Resupply Services 2 (CRS2) contract.

"ULA is pleased to partner with Sierra Nevada Corporation to launch its Dream Chaser cargo system to the International Space Station in less than three years," said Gary Wentz, ULA vice president of Human and Commercial Systems. "We recognize the importance of on time and reliable transportation of crew and cargo to Station and are honored the Atlas V was selected to continue to launch cargo resupply missions for NASA."

The two awarded Atlas V missions will carry pressurized and unpressurized cargo to the International Space Station (ISS). The first mission is set to lift off in 2020 fr om Space Launch Complex 41 at Cape Canaveral Air Force Station, in Florida. The second contracted mission is scheduled to lift off in 2021. Dream Chaser will launch atop an Atlas V 552, with a dual engine Centaur upper stage.

"SNC recognizes the proven reliability of the Atlas V rocket and its availability and schedule performance makes it the right choice for the first two flights of the Dream Chaser," said Mark Sirangelo, corporate vice president of SNC's Space Systems business area.  "ULA is an important player in the market and we appreciate their history and continued contributions to space flights and are pleased to support the aerospace community in Colorado and Alabama," added Sirangelo.    

The Atlas V has received NASA's highest and most rigorous Category 3 Certification, which allows the Atlas V family of launch vehicles to fly NASA's most complex and critical missions.

The Dream Chaser spacecraft has been in development for more than 10 years, including six years as part of NASA's Commercial Crew Program and leverages more than 40 years of NASA spaceflight and space shuttle heritage. In 2016, Dream Chaser was selected by NASA under the CRS2 contract to transport pressurized and unpressurized cargo to and fr om the ISS with return and disposal services.
