Цитата: undefinedVirgin Orbit ignites LauncherOne rocket during first launch demo, mission safely terminated

MAY 25, 2020

PRESS RELEASES



Mojave, California — May 25, 2020 — Virgin Orbit, the California-based satellite launch company, conducted a launch demonstration of its innovative air-launched rocket today in the skies over the Pacific Ocean just off the California coast. The company successfully completed all of its pre-launch procedures, the captive carry flight out to the drop site, clean telemetry lock from multiple dishes, a smooth pass through the racetrack, terminal count, and a clean release. After being released from the carrier aircraft, the LauncherOne rocket successfully lighted its booster engine on cue — the first time the company had attempted an in-air ignition. An anomaly then occurred early in first stage flight, and the mission safely terminated. The carrier aircraft Cosmic Girl and all of its crew landed safely at Mojave Air and Space Port, concluding the mission.

"Our team performed their prelaunch and flight operations with incredible skill today. Test flights are instrumented to yield data and we now have a treasure trove of that. We accomplished many of the goals we set for ourselves, though not as many as we would have liked," said Virgin Orbit CEO Dan Hart. "Nevertheless, we took a big step forward today.  Our engineers are already poring through the data. Our next rocket is waiting. We will learn, adjust, and begin preparing for our next test, which is coming up soon."

The company's next rocket is in final stages of integration at its Long Beach manufacturing facility, with a half-dozen other rockets for subsequent missions not far behind. Virgin Orbit's decision to begin production of multiple rockets well in advance of this test flight will enable the team to progress to the next attempt at a significantly faster pace, shortly after making any necessary modifications to the launch system.

Updated 8 p.m. Eastern with comments from company CEO Dan Hart.

WASHINGTON — Virgin Orbit's LauncherOne failed to reach orbit in its first launch attempt May 25, with the mission "terminated" moments after the rocket's release from its aircraft.

The company's "Cosmic Girl" aircraft, a modified Boeing 747, took off from the Mojave Air and Space Port in California at 2:56 p.m. Eastern, after a launch attempt May 24 was scrubbed because of a faulty sensor on the rocket. After a 54-minute flight to the designated launch zone, near the Channel Islands off the Southern California coast, the plane released the LauncherOne rocket from its left wing.

However, Virgin Orbit, which did not provide a live webcast of the launch but instead offered updates via social media, tweeted moments later that while there was a "clean release" of the rocket from the aircraft, "the mission terminated shortly into the flight."

"We ignited the engine, and it looks like successfully," Dan Hart, chief executive of Virgin Orbit, said in a phone interview a few hours after the launch. "It flew for a handful of seconds, and then we had an issue."

Hart said that what that issue was — an "anomaly" as described by the company in a statement after the launch — is not yet known. It did, though, cause the NewtonThree engine powering the rocket's first stage to shut down.

Virgin Orbit acknowledged that achieving orbit on a first launch would be difficult, noting that, based on historical records, only about 50% of first launches of new vehicles are successful. The second LauncherOne rocket is nearing completion at the company's factory, with several more in various stages of production.

Company executives emphasized prior to the flight, including a media briefing May 23, that simply igniting the NewtonThree engine in the rocket's first stage would be a key milestone for the flight. Hart said that the events leading up to the release and ignition of the first stage went smoothly.

"What we did today is really demonstrated the challenging aspects of air launch," he said. "Even though it was not as long a flight as we'd liked, we did burn down quite a lot of the risks associated with flying, and learned a lot about how the vehicle behaves."

Hart said that engineers will spend the next several weeks reviewing the data from the launch attempt, while others continue working on the next LauncherOne rocket. The results of the investigation may lead to additional testing of that next rocket or other changes, the extent of which is not yet clear.

LauncherOne started as a Virgin Galactic project, announced by company founder Richard Branson at the Farnborough International Airshow in July 2012. As originally conceived, LauncherOne would use the same WhiteKnightTwo plane built to serve as a carrier aircraft for its SpaceShipTwo suborbital vehicle.

In 2015, Virgin Galactic changed course and acquired a Boeing 747 from airline Virgin Atlantic; the name "Cosmic Girl" dates back to its use by the airline. Using a 747 allowed the company to increase the size, and payload capacity, of the rocket.

Virgin Galactic spun out the LauncherOne project into a separate company, Virgin Orbit, in March 2017, based in Long Beach, California. It later established a wholly-owned U.S.-incorporated subsidiary, VOX Space, to work with national security customers.

Virgin Orbit has gradually built up a manifest of commercial and government customers. Hart said in a May 23 call with reporters that the total value of its manifest is in "the hundreds of millions" of dollars but did not give a specific figure. The company set a price of about $12 million a launch prior to entering service but he said that "pricing will follow the market as we get into full operations and we'll adjust accordingly."

LauncherOne is one of a growing number of small launch vehicles intended to provide dedicated launches of small satellites. While there are more than 100 such vehicles in various stages of development, by some estimates, Hart said he didn't see nearly as much competition for his company.

"I don't see it as very packed," he said of the market in the pre-launch media call. "We're differentiated in our air-launch capability, which gives us much, much higher flexibility, and even mobility."

Most of those small launch vehicles that serve as potential competition to LauncherOne are still in earlier phases of development. "Launch is still a highly, highly needed commodity," he said.

Despite failing to reach orbit, Hart said both he and his employees were remarkably upbeat. "The mood was actually very high" among the LauncherOne team, he said, because they made it through countdown and release. "There's a lot of pride in the team that we successfully did that, and we did it so uneventfully."

"The sense I have from the whole team is that there's no doubt in anybody's mind that we'll quickly get to root cause and address it."

Mission Recap: Launch Demo

We said the main product of this flight would be data, and wow, did we get a lot of it! After diving into our early analyses, we wanted to share more about the flight — including both the many things that went well and what we know about the areas where we'll need to improve.

Check out our newest blog post for a more thorough recap of the flight, and to see where we're headed next as a team more excited than ever about the utility of our launch system.

TECHNICAL UPDATES

https://www.youtube.com/watch?v=CNJib8lJY1E

As we've delved into the data from yesterday's flight, the more we see, the happier we get. We've taken an enormous step forward as a team, and we wanted to share more about the flight, including both the many things that went well and what we know about the areas where we'll need to improve.

The context of everything that happened before the release of the rocket is incredibly important, and we'll describe that in detail below. But we won't make you wait for the part that's of most interest.

WHAT HAPPENED?

For about 9 seconds after drop, the flight went perfectly. Through some of the most challenging portions of our flight — release, the controlled drop, the rocket's ignition sequence, and the initial portion of guided, powered flight — every part of our system did exactly as we designed it to do. We have solid data from hundreds of channels and sensors — and in looking at those, we see performance that is well-matched to our predictions and to the extensive data we have from our models and ground tests. This means that we have proved out via flight the foundational principles of our air-launch operations, which is the key thing that separates us from our peers in the industry.

About 9 seconds after drop, something malfunctioned, causing the booster stage engine to extinguish, which in turn ended the mission. We cannot yet say conclusively what the malfunction was or what caused it, but we feel confident we have sufficient data to determine that as we continue through the rigorous investigation we've already begun. With the engine extinguished, the vehicle was no longer able to maintain controlled flightbut the rocket did not explode. It stayed within the predicted downrange corridors of our projections and our Federal Aviation Administration (FAA) launch license as the vehicle fell to the ocean, posing no risk to public safety, no danger our aircrew or aircraft, and no significant environmental impact.

SO, WHAT DID THIS LAUNCH DEMONSTRATION PROVE?

Our Launch Demo was the world's first attempted orbital launch from Mojave Air and Space Port. One of the core capabilities we've been working to develop is the idea of a truly mobile launch infrastructure — and yesterday, we completely demonstrated that capability. The infrastructure LauncherOne requires is dramatically different from any existing launch system. For this launch demo, all we needed from the airport was a small plot of land at the end of a taxiway and access to a runway.  Everything else we brought in ourselves — coming in on local roads or on our carrier aircraft itself. This low infrastructure footprint is the key to truly responsive launch and a new kind of global launch capability. And we've now proven it works.

As part of that, we have proven out our own fully transportable ground operating system. All of the trailers that we use to transport our rocket, mate it to our carrier aircraft, fuel and pressurize it, and service our payload were transported by public roads to the spaceport. Indeed, even some of our most critical ground stations for receiving telemetry were driven and parked in place. Again, this proves out our ability to quickly bring our launch capability wherever it is needed — a whole new category of launch service. Our Launch Demo was also conducted under a Commercial Space Transportation License issued by the FAA, the first time we have ever operated under such a license. Furthermore, this launch was conducted independent of the U.S. federal ranges, important national institutions that can nevertheless impart significant cost and schedule impacts on traditional launches. Apart from coordinating the airspace, our system is beholden to no one's schedules other than our customers', our own, and Mother Nature's.

One key technology that is required in order to move away from reliance on those federal ranges is an extremely robust autonomous flight safety system. While rockets traditionally rely on complex ground systems at the ranges to monitor the flight and terminate the mission if the flight ever goes out of the approved launch corridor, the new generation of launch vehicles are doing this job autonomously. Yesterday, our rocket demonstrated its capability to correctly know when we are in that corridor and when we are not — something we verify during our "cold pass" prior to dropping the rocket. Thankfully, this system was not needed during yesterday's mission, but it functioned perfectly throughout the flight.

When Cosmic Girl and LauncherOne took off from the runway at Mojave Air and Space Port just before noon yesterday, that marked our first flight with cryogenic liquid oxygen loaded into the rocket — and only our second ever flight with cryogenic materials on board. Capping an extensive campaign of ground testing, this milestone allowed us to prove out key aspects of the technology behind our linerless composite tanks, which held up to the loads of flight under the wing of a widebody jetliner and the release maneuver while carrying a full load of cryogenic oxidizer.

After a swift flight out to the drop point and a cold pass around our racetrack — the planned loop where we ensure the system autonomously detects when it enters and exits the allowable launch corridor, in addition to verifying telemetry locks — we entered into and executed a terminal count for the first time outside of dress rehearsals. A universal aerospace practice that has been made famous by countless documentaries and films, the terminal count is the final sequence of checks and polls that culminate in a rocket's ignition and flight. These countdowns always require an uncompromising level of precision, communication, and choreography — and our team pulled it off without a hiccup, hold, or scrub.

As the terminal count approached zero, our carrier aircraft went into our pitch-up maneuver, climbing steeply and achieving a flight path angle of about 30 degrees. Exactly on cue, we cleanly released the LauncherOne rocket from the pylon under the wing of our 747. As planned, the aircraft quickly banked away from the rocket. The rocket itself flew gracefully, with complete control, perfectly matching our predictions and further validating our aerodynamic models.

A few seconds after drop, the rocket trigged its ignition sequence. On our first ever attempt, we achieved in-air ignition and steady state-operation of our main stage rocket engine. The use of liquid-fueled rocket engines for air-launched vehicles is almost unheard of outside of legendary programs like the X-1 and X-15; and indeed, no one before us had ever completed such an ignition of an orbital-class rocket engine.

Once the engine ignited, our guidance and control system controlled the rocket in powered flight and steered it along its trajectory, all as predicted by our 6-DOF analysis.

Each of these items is a huge achievement for our team, and we are thrilled to have accomplished so many of them in our first launch demo mission.

WHAT NEXT?

With more confidence than ever in our design philosophy and the utility of our one-of-a-kind launch system, we're determined to reach space as soon as humanly possible. Clearly, we have things to learn and something to fix, but our engineers, technicians, and flight crew have taken a moment to celebrate and are now precisely and thoroughly dissecting the data.

Meanwhile, our integration team is hard at work preparing our next rocket, and the one after that, and several more. If hardware changes are needed, we'll be able to make them quickly, thanks to our vertically integrated, state-of-the-art rocket factory. And if we decide we want to run a few experiments, well, we've got a factory full of flight hardware we can use for whatever tests we need.

It's too soon to say exactly when our next launch demo will occur. But we can confidently say that we laid the groundwork long ago for us to build on this launch demo quickly and skillfully. We're excited to take the next step on our journey to open space for good.

Dan Hart says that on the May launch demo, a high-pressure feed line broke, keeping LOX from getting into the engine. Identified what fixes are needed in the engine, and targeting a next launch before the end of the year.

Wrapping Up Our First Launch Demo, and Looking Ahead to Launch Demo 2

AUGUST 3, 2020  ●  FEATURED/TECHNICAL UPDATES

This past Memorial Day, Virgin Orbit took a major step forward as a company and conducted our first Launch Demo. As you've read before, we built on years of design and preparation to step into our first launch campaign; and on our very first attempt, our team pulled off a picture-perfect loading operation, take-off, captive carry, terminal count, release, and ignition, and achieved powered flight. It was a smooth operation, thanks to the intense focus of an incredibly talented team.

You've also seen that that during our first stage flight, our main rocket engine shut down prematurely, bringing our experimental flight to an end — but only after we had demonstrated all of the key technologies of a truly unique air-launched spaceflight system, differentiating our launch system from every other system on the market.

Within minutes of our flight crew safely touching down at the Mojave Air and Space Port, our full attention turned to an investigation of all of the copious data from the flight. We had worked hard to ensure we'd have a mountain of data from that demonstration flight, and with our highly instrumented vehicle feeding data down to four ground stations, plus additional information from our carrier aircraft and chase plane, that work paid off.

Although we'd hoped to truly defy the odds and make orbit in our very first test, we were still thrilled to have reached milestones that only a small handful of others have ever gotten to celebrate. But we didn't spend too much time partying it up. By the evening of the same day, we were deep into the process of both celebrating the wins and how closely performance matched prediction and, of course, figuring out why our main engine had shut down, ending the flight.


RESULTS FROM OUR INVESTIGATION

We knew the odds of getting to orbit on our first attempt were slim well before our wheels started to roll down the tarmac, and so we were ready for any outcome. We had our plans ready and an investigation team identified before the countdown began. So as soon as the flight concluded, we were able to get started. To ensure we left no stone unturned in our quest for answers, we added strong independent voices to the team, calling upon industry legends Jim Sponnick and Mark Wilkins as well as the world-class team at the Aerospace Corporation to give us their straight-up advice and opinions along the way.

Soon, we were able to identify the cause of the failure that ended our first Launch Demo: a breach in the high-pressure line carrying cryogenic Liquid Oxygen (LOX) to our first stage combustion chamber due to a component failure. Without a supply of oxidizer, that engine soon stopped providing thrust, ending our powered flight and ultimately the test itself.

In the business of launch vehicles, finding the direct cause of any failure of any flight is incredibly important, but certainly not sufficient. In order to truly get to the root of the issue, it is important to ask why after why after why.  If the answer to the first why is "because the high-pressure LOX line failed," then the second why must be "why did it fail?" That in turn must be followed by more whys— including "why didn't we anticipate this failure," "why wasn't this failure observed in our earlier testing," and more. To all of these, you must add in a healthy dose of "what else could have happened," "what would this failure have looked like if it occurred at a different point in the mission," and hundreds more questions. Creating a robust fault tree or fishbone diagram is important, especially for those visual learners.

In the two months since that milestone test, we've asked ourselves those questions and our team has come up with clear insights and answers. Engineers, technicians, and inspectors have been working hand-in-hand (well, the COVID-19 equivalent of hand-in-hand) to validate those answers. We've put our hardware through a punishing barrage of tests to shake out any hidden surprises that might otherwise doom us to repeat the mishap.

Now, we're putting the finishing touches on that investigation; and while we aren't quite done, the major findings and the corrective actions are clear — and we're well under way with fabricating new parts and putting those actions into play.


CHANGES AND IMPROVEMENTS

In implementing tweaks to LauncherOne for our next flight, we've taken a "belt and suspenders" approach; that is to say, fixing the obvious issues we observed, and also proactively addressing issues we didn't observe but fall into the realm of possible contributors.

A battery of tests of our components and systems has enabled us to re-anchor our understanding of the physical stresses and leak paths in the system, and to reassess the design and the operation of every component. On the basis of those results, we are strengthening parts of our high-pressure LOX feed system and increasing some of the operating margins with an eye towards maximizing robustness and reliability.

We're also able to safely pass on more good news about the system to our customers.

One of the datasets that pleased us the most from our first Launch Demo was what we saw in terms of the vibrations that satellites riding on our rocket will experience. Our structural dynamics engineers are by nature a fairly conservative group, and have been appropriately cautious with all of their analyses, especially when it comes to our customers' precious cargo. Our analysts need proof before they will remove uncertainty. Last year, they updated their projections based upon our flight test campaign; now, thanks to the insight earned from our Launch Demo, they have further reduced our random vibration environment predictions. After years of under-promising on that front, we're pleased now to state with the confidence only afforded by flight data that we'll provide our customers a gentle ride.

Of course, after an intense journey to first launch, and all the lessons learned and teamwork along the way, it must be said that the biggest improvements in the system between Launch Demo and Launch Demo 2 will be the improvements to ourselves. We've always felt we have the best team in the business, and the skills and the perseverance of our team really shone through in what we accomplished in May. It takes a lot to smoothly, professionally move through a fully automated countdown, transfer control of the system to a small crew of four on our 747, execute a picture-perfect release, and more, and none of that happens by accident. But the experience of the whole launch campaign — not just the flight, but the work that led up to it — taught us a lot. Our self-reflections along that road and now our data review has taught us still more.

Our team is now more experienced and better prepared than ever. Our tools and processes have been honed by our first launch campaign. We've experienced both joy and frustration and every emotion in between, and now we're ready for the next chapter.
