Rocketplane Global

Chuck Lauer starts by informing us that Kistler and Rocketplane have been split off into separate companies. Still want to resurrect Kistler–only two-stage reusable out there.

Bottom line was that markets didn’t buy the value proposition that NASA could be a reliable anchor customer.

Drawing contrast between their max gees and Virgin’s. Rocketplane is four, Virgin is six. Thinks it will be a significant difference. In terms of market research, early studies had to spend a lot of time educating the customer. Now there’s a lot more awareness of various products (runway takeoff and landing single vehicle, versus air drop versus vertical) and it would be useful to update the market research.

Need public/private partnership unless you’re a billionaire like Jeff Bezos. They are continuing to partner with Oklahoma, and the action is primarily between the companies and the states, not the federal government. Even Florida is waking up the fact that the entrepreneurial space community is the future.

Marketing strategy is to work with partners all over the world. Going after one third of the tourist market. Expect 80/20 tourism/other (microgravity science and microsatellite), but the latter may be a bigger market than they think. Looking at charter flight model with things like reality teevee shows, sponsorship of contests (currently have one going with Nestle–paying full price for two seats and giving them away). Can see the Kitkat promotion at nestle.fr. Another contest in India for a multi-media company with a four-episode show to pick the winner. Winner’s sound bite: “I want to see what it’s like to pee in space.”

They can provide a blank canvas for corporate customers without having to compete with a brand (as they do with Virgin).

Lost a year plus of schedule in 2005/2006 as a result of the focus on COTS. Original plan was to build a couple four-place Learjet version, and then build a bigger version for more throughput. Since then have taken a step back and decided to go directly to the larger vehicle, built from scratch. New vehicle is pure cylinder fuselage, cabin the size of a large SUV 2+2+2 seating, with more revenue per flight but no increase in ops costs. Upgraded to an after-burning turbo jet with higher thrust, shorter takeoff roll, higher air-breathing altitude.

Frank Nuovo designed the interior of the aircraft (former head cellphone designer for Nokia). Everyone sees out the front (even in the rear seats), has their own window, and a personal video display. Will show tail camera view during ascent. Video screen will also be selectable for different angles. May use Google Earth overlay on monitor to know what you’re looking at.

[Update at 11:30 AM MST]

I got pulled away from the rest of the Lauer talk, but Clark Lindsey has some good notes, as well as more from the Frontier Astronautics talk.

Armadillo

John Carmack is starting off with a video of Lunar Landing Challenge, showing the failed attempt to win last fall.

Likes the new single-tank design compared to the old quad. It’s easier to service, though a little harder to transport because it’s much taller.

Seeing views that we hadn’t seen at the time, from the three on-board cameras.

Now showing a burn of methane engine that they’ve been developing with NASA.

Now have four modules of the six that they plan to build their suborbital vehicle. Landing gear turns out to be one of the heavier items, as heavy as the tank. Sticking to dual tanks and single engine on each module. 800 psi pressure tank, with rubber landing pads. Thus tank is also landing gear.

Steps to commercial vehicle. Some debate whether differential throttling will work for control. Recent experience indicates that it is sluggish to respond, because throttling can’t be done fast enough on a peroxide engine, but a bi-prop engine may be more manageable.

Definitely disappointment after losing the cup. Thought they’d done everything they needed to prepare for. They’d done many test flights, including five 180 second flights (long enough to go to space). Had three vehicles, any one of which could do the ninety-second challenge. But they had five starts with three wrecked engines. Still not sure what the problem was, but think that (sorry, going to fast to capture it all), but think it had something to do with cooling jacket capacity and start-up processes that resulted in fuel entering the chamber prematurely. BIggest difference was that they turned the vehicles faster at the cup than during normal tests, and there could have been slight differences in chamber pressures or fuel ratios at a given point in time that had catastrophic results. May have had an assembly error (leaving out an O-ring that resulted in a fuel leak), but can’t be sure.

Disheartening, but compared to all the other hardware at the airshow with thousands of flights, they couldn’t have the statistical confidence as those military aircraft. Learned a lot of lessons. Don’t expect it to work the first time. Even with modern engineering practice, it won’t happen. Not arrogant enough to think they’ve solved all the problems, or even know what they are. Expect to lose several of the modules in flight testing. But once they find the problems, they’re confident they can solve them. On propulsion, engine now starts and stops like a light switch. Expecting high-speed aero problems.

On business scale issues, things are accelerating. Half a million in contract work, NASA and a commercial customer not to be disclosed. Starting to talk more like Jeff Greason now–transitioning from hobby to business. Won’t sell components, because integration is critical. Will sell functional systems (such as propulsion). Currently at around 5000 lbf thrust, will sell for a couple hundred thousand bucks. Will sell complete vehicle for half a million. Talking to Lunar Google X-Prize teams. Won’t warrant that it will land on the moon, but if they want to buy one for testing, he’ll sell it. Has very little confidence in Google Lunar X-Prize–doesn’t think anyone has what it takes. Talking to aerospace companies about sensor suite testing and lunar simulations. Still thinks highly of suborbital passenger market. Thinks there’s a market, and has all the pieces: propulsion, control, insurance, etc. Not worried about schedules, because SS2 continues to slip.

Had hoped that he was past the point where he didn’t have to invest any more, but did recently. However, more of a float issue, or loan, until some other things come in. “Perseverance and determination will get us there.”

Problem with LLC: once a year demonstration is the worst thing for a technical challenge. Adds pressure for tough decisions that can distract from main commercial goals. Afraid to do boosted hops at higher altitudes because they don’t want to risk if for the challenge. Have three vehicles, but last year’s experience shows that’s not enough for redundancy. Ready to do it now, but have to wait until end of year and keep hardware available for it.

[Update a few minutes later]

Clark Lindsey has more on Armadillo, and a report on the previous talk on laser launch by Jordin Kare.

XCOR Presentation

Dan DeLong starts off by telling Paul Breed that they learned a long time ago at XCOR that green is bad, stop right now.

This talk is more than just Lynx, they’ll be talking about the other things they’re working on as well. Can’t talk about the Rocket Racer, because Rocket Racing League controls information on that. The piston pump is working well on it, though, and it’s the same pump that will be used on the Lynx, for both fuel and LOX.

There is no more Xerus. The concept has been changing, business model changing, aero changing, and they decided that they have a new stable configuration that they can give a name to. That is Lynx.

They’re having trouble with the computer display. Making jokes about Microsoft, and saying that their flight software won’t be windows. Dan talking about conversation he had night before with Russ Blink of Armadillo, with Russ saying that he’d rather fly a rocket controlled by a computer than one controlled by a human. Dan responded that while it made sense to do a vertical vehicle with computers, but it didn’t seem that good to do it with software based on a package called “Doom.”

Showing a flow chart of a meat hunt, with overanalysis. Their emphasis is analyze a little, and test a lot.

Showing various past projects–NRO thruster, DARPA LOX pump, methane engine.

Showing video of putting bomb inside of a methane engine to test combustion stability. Four bomb tests, all successful.

Talking about the valves that they’ve developed, because none were available that met their needs. Also doing own composites for the Lynx. They’ve come up with a glass-fibre and teflon resin, neither of which will react with oxygen.

Not talking about Lynx. Sunk cost so far $7m, with an estimate of $9M to complete. Showing a video of 50-lbf attitude control thruster, running nitrous/ethane, that will sit in the strakes. This video wasn’t shown at the press conference.

Mark II will have hard points on outside. Will carry upper stage dorsally, that can put 10-20 kg payload into LEO. Purpose of the contract is not to help build vehicle. It’s for analysis, demonstration and knowledge sharing of its responsive features. Air Force is looking for Operationally Responsive Space (ORS). Air Force has space they need the “OR.” XCOR has the “OR” but not the “S.” Everyone understand that you can’t be cheap at nine times per year, but because XCOR is commercial, they have to make it cheap, which happens by flying often. So Air Force gets the benefit.

Lynx requirements:

Supersonic
Two people
Fly under FAA-AST rules

Goal was to build smallest vehicle that met those requirements.

Showing video of firewall test stand, successive engine runs with increasing pauses, with minimum off time of two seconds. About a half second to start up.

Showing video from press conference now.

Fuel is carried in wing strakes, LOX in fuselage. About two gees at burnout, heading straight up at Mach 1. Mark II will be three gees. Landing speed about 95 knots, takeoff about twice that.

Unreasonable Rocket Update

Paul Breed is an entrant in the Lunar Landing Challenge. He didn’t make to last year’s attempt, but expects to do so this year.

They are literally doing everything in their garage. Last year, they built an engine and ran it and it was perfect. They built four more, and it didn’t work so well. Showing a film, taken on one Saturday..On the first burn, they saw a green flash, which meant a meltdown of the copper combustion chamber. It turned out that they used a different kind of solder. Then he showed a stability and control test vehicle that was neither controllable or stable. Then their four-quadrant vehicle turned out to be too complex, with too many valves.

This year, they’ve switched to a monoprop vehicle using peroxide, with sodium permanganate decomposition. New vehicle is spherical tank, using McMaster car parts. Will be tested next week. Doing testing of stability and control unit with a large RC helicopter, which they don’t have to go out to the rocket test site (four hours away) to test. Vehicle will be aluminum. Expect to static fire full vehicle in two to four weeks, with first flight test in eight weeks.

New Wyoming Space Company

Tim Bendel, of Frontier Astronautics, is giving a presentation on how to address the gap between the ability of garage-based startups and larger companies to raise money. Not very many angels with money who are interested in space who aren’t already doing it.

Giving a history of the Zeppelin. After the count lost his first ship, he threw in the towel, because he’s lost all his money, but a lot of Germans sent him money, and he ended up with more than he had started with. Are there space enthusiasts who could do the same thing?

Talking about Warren Buffett’s stock, and its high value that he refuses to split. Independent holding companies evolved by purchasing a few shares of Berkshire stock, and then issuing new, lower-priced stock based on that asset.

His proposal is to gather small investors for the holding company, put their money into escrow, and fund start-up space companies off the interest. Different “flavors” or classes of stock would be issued, with different Class A escrow accounts, which could be associated with specific start ups.

Unfortunately, most of the info is on his charts, which I can’t read because I’m all the way in the back (where the laptop power is), and too dense for me to quickly transcribe even if I could.

He claims that it avoids sunshine laws, according to SEC lawyers that they’ve talked to. The basic idea is to provide a means for small investors to invest in small companies, albeit indirectly.

Issues: Have to pay for licenses, need to be broker/dealer, etc., a lot of paperwork. Probably about a hundred thousand bucks to get started. Goal is to do it for profit, in addition to helping space industry. Makes money on trades, but could also use other investment tools, such as puts and calls.

Has a business process patent on it, needs about a quarter million to start up.

Hard for me to evaluate it, given my funky state of consciousness, and inability to look at the numbers. I’ll talk to TIm about it later.

The History And Future Of Spaceplanes

Jess Sponable of AFRL is giving a talk with the post title.

Jess starts out by noting the upcoming fifteenth anniversary of DC-X flight tests.

Common vision between industry and government of reliable, routine, diverse and affordable space access. Confident that it is coming at us, though not sure when.

Discussing HAVE REGION program of the 1970s, which was to develop structural concepts for potential space planes. Subject to thermal and aero loads in test chambers on the ground. All airframes came in within three percent of estimates. Validated loads, with some articles tested to destruction, some deliberately, some otherwise. Best vehicle was Boeing RASV. Honeycomb structure, with very little metal. Highly classified at the time, but now all declassified. Came very close to SSTO weightwise, but concerns were about durability and operability.

Talking about NASP, now. We learned that it’s really really hard to get an airbreather all the way to orbit. Have to spend too much time in the atmosphere to take advantage of the scramjet. Had high ISP, but horrible engine T/W–even worse than conventional aircraft engines, and hydrogen fuel was required, which required very large tanks because of its low density. It was a very complex vehicle in terms of shapes, and the heating problems of flying that low in the atmosphere at such higher velocities were very challenging. It would have been a very large vehicle.

Now going on into other SSTO projects. Points out that Mike Griffin actually started the DC-X program while at SDIO. DC-X/XA was the best program he ever worked on. It didn’t have to work because it was a test vehicle. They had a 26-hour turnaround time. Pete Conrad was determined to demonstrate three flights a day. Very low infrastructure required (~$600K). First ever composite linerless oxygen tank, long before X-33 tank failed a few years later. NASA tried X-34 and X-33 which both failed.

A missed opportunity was not extending the DC-X program with a more integrated airframe and fly to Mach 8, for about $90M. Once you’ve flown something and developed that experience base, it’s cheaper to extend it. Had they gone for Mach 8 from the beginning of DC-X, it would have been a billion dollar program.

Lesson learned was that two-stage, hydrocarbon fuels is a winner, despite the loss in Isp, because the vehicles are so much smaller. Isn’t saying that SSTO isn’t the right answer, and that you couldn’t build a demonstrator, but it might not be operable.

The reason that the commercial sector is important is because we don’t have any choice. We don’t have the money to do it the way the government does. Build quick, reduce risk will be a quarter of the cost of government program business as usual.

The good news is that the entrepreneurs are starting to engage, and they’re putting a lot more into it than either NASA or the Air Force are interested in. Talking about Bezos, Branson, Musk, Carmack. John Carmack has a great approach–just go build it.

As naval power was built on the back of maritime power (ocean commerce) the Air Force will have to engage with the private sector. AF is continuing to engage in technology push toward operability. Will trade performance gains for operability, which also pushes toward two-stage. Building a ground-based demonstrator tank (common bulkhead) that they want to evolve into a Mach 7 test vehicle. Technology will support wide range of applications.

Mach 12 vehicle will be about the size of an F-15. Not big vehicles with hydrocarbons–lots of room for growth.

Pure energy price to put a person into orbit is about $76. To actually approach that cost will require much higher flight rates than are required by the Air Force, which is why they have to partner with the private sector and private markets.

In giving XCOR the contract, they’re not paying them to build a flight test vehicle–they’re doing that with their own money. They’re paying them for technology development, and it will be shared with the industry. “Build an industry, not just a government program.”

Increase in the of knowledge doubling dramatically increasing. By 2020 knowledge will be doubling every 73 days. Time is on our side. AFRL will be continuing to push and mature technology that are beyond our horizon, but some of them will be helpful to us now.

Technologies are more complex than initial Wright work for airplanes, but we are getting to the point that we can do amazing things with small teams. Discussing technology exchange forum in Dayton where they will present their technologies to private developers to make them aware of what the Air Force has. Also a three-day workshop in New Mexico for the DC-X anniversary to discuss lessons learned for the future.

TIVO’d Live Blogging

This is what I would have live blogged at yesterday’s XCOR press conference if I’d had an Internet commercial.

———————————————————————-

Doug Graham gives an introduction. Leads off by introducing Esther Dyson.

Took it for granted that she would be going to the moon, but space was like a priesthood, for NASA and big companies, not for ordinary folk. If you wanted to go into space you went into industry and lost your entrepreneurial initiative, or you wrote science fiction (Pournelle). PCs have made computing cheaper by orders of magnitude. The Internet was developed by the government, but its potential didn’t explode until it was turned over to the commercial sector. In the software world, you can build a business by copying software, but you can steal XCOR’s plans, and not be an XCOR and not build a Lynx. Not qualified to judge the technology. But she can judge the customers, and the people and their approach. She’s investing in Jeff and the team that he surrounded himself with. Real-world company. Not making wild-eyed promises, but transparent and making promises they will be held accountable for.

Greason: Just notified that Air Force wants to continue to fund their SBIR, and the process would make parts of the vehicle public over time, so announcing now. Most people wouldn’t be able to tell the last few versions apart. Also wanted to let potential travelers know what else was out there. Airframe designed from scratch to be optimized for the engines. Fly from the ground out into space, see stars, earth curvature, earth below, experience weightlessness. Looking at different ways to package people in vehicle, and shifted from Xerus to Lynx about three years ago. Referring to Metacomp Technologies CFD support. Started with engines in 1999, because it was clear that this was the critical technology at the time for building these kinds of vehicles. High flight rate is critically important. Allows a much smaller vehicle, with single passenger, and still fly as many people with a smaller vehicle that flies less often. Regulatory regime is unique in the world. By requiring developers to release safety records, there wil be competitive pressure for safer vehicles. High flight rate, low cost propulsion systems will be able to offer prices at roughly half the price of competitors. Smallest vehicle that they can build–if they could figure out a way to fly half a passenger they would do that. Not that last step–just one more step on a roadmap they laid out years ago: low suborbital, high suborbital, orbital. Thinks that this business is important, and that demonstrating a vehicle like this can make money will bring new capital into the market.

Rick Searfoss: Was convinced would never fly into space again after leaving NASA. After working with XCOR, became convinced that it was possible, except this time can take wife (if she wants to go). Showing video of virtual vehicle being rolled out of hangar, checking out engines on runway, lighting it up, and on its way. Similar to high-performance fighter aircraft. Flight test and ops will take place same place (initially) as Yeager’s first flight. All-liquid rocket propulsion technology. Using same approaches as X-15 and Shuttle–dead stick landing. Well proven and easy to do, except they have the ability for go-around, reducing risk. Absolutely enthralled with the prospect of flying Lynx through test phase to the point that they can safely fly the paying public. XCOR an impressive organization. Lots of people want to get into the game, but very few really have capability to make it happen–XCOR is one of those. Scalable, developable, vey amenable to flight-test regime. As a test pilot he loves it. Flight test isn’t about taking risk–it’s about mitigating and controlling them while expanding the performance envelope. Most impressive thing about space is the view (riding up front, next to piot). Weightless experience is more different than you can imagine, but still second place to the view. Excited about working with this technical team to make it a reality, and open up space to many people in the future.

LA Times: What is state of vehicle.

Vehicle is sufficiently designed that they can start to build.

Pressurized cockpit, suit?

Yes, pressurized cockpit with life support, but will have pressure suits for additional layer of safety. Searfoss: Developing suits with Orbital Outfitters, which will be lighter and more manageable to wear. Not pressurized, and can fly with faceplate open. Dyson: You get to wear a space suit, and keep it.

Will passengers need physicals?

Missed the response.

Can’t address price point, because they are not the retailers. “our price to them is sufficiently low that the can charge about half the competition.

How large is the market. Jeff know one knows for sure, but a lot of research has been done. Dyson: a lot of people with more money than time. They can’t do a safari in Africa, but can do this in a day.

some training needed for suit operations, but shouldn’t take more than a few days and doesn’t have to happen right next to the flight.

Is 200,000 feet high enough? “More than high enough to satisfy the people who haven’t flown at all. By the time that market is worked off, will have higher vehicles. Direct competitor is Scaled/SSCompany. Very different concepts. Doesn’t think that any one will be the way to go. Different vehicles for different experiences. They only have one passenger with a co-passenger experience. Theirs is direct from runway to space, with no mother ship.

Test flights first half of 2010.

Why not carried aloft, to shorten rocket burn, like SS2? Expect that there will be competition on cost, so rather than focus on how fast to get there, but how to design a system that’s cost effective to operate, but be able to compete as well. That led to the engineering choice of doing it in a single vehicle. Trade off is to have more advanced rocket propulsion, which is why there started there.

Why suborbital when the problem is orbital. Esther: likes speciation–going after a real market niche in the short term, with real technology that will continue to involve over time. It’s a good business case. Jeff looks forward to the day that he can announce an orbital system, and you’ll be able to see the heritage from what we’re doing today, and obvious that a step-wise approach is better than “hail Mary” to orbit.

Air Force contract more important psychologically than financially. Very validating to have them watching over shoulders and trusting them. Don’t have all the money yet, but don’t expect any problems based on current discussion with investors. Ride is about thirty minutes, with last twenty a glide home. Only difference between Lynx one and two (none external), but 2 will be full-performance version. Can fly one without waiting for ultimate perfect vehicle.

Is it high enough to be in space? Tee-shirt factor is an issue, but still a big market for early adopters. Not technically in space (50 miles, 100 km), and that will obviously be worth more, but they will get to that point. Price allows multiple flights. In terms of passenger sizing, Greason is the model (because he wants to fly, and because he’s 95th percentile).

Total burn time is about three minutes, weightless about a minute and a half.

Start with taxi tests, then runway hops, then fly arounds, then subsonic (thirty or forty), then carefully through transition, then take it to the limit. Fifty to seventy to a hundred flight tests.

What infrastructure required? Franchise to other places in the world? Do you expect Mojave to be upgraded to New Mexico class?

No infrastructure required except runways and air space. Doesn’t expect California taxpayers to build them new facilities. Expects to fly all over the world, because people want to operate from their own turf.

Do you need to be supersuper wealthy? Comparable to Everest operation. Had two teachers who bought flights on Zero Gee at 3500. Was it worth it? Absolutely, will share with students and remember forever. Greason: Of course price will come down. Aren’t we glad that people bought plasma teevees and cell phones so that now we can all afford them? Never be dirt cheap, but could come down to the price of a cruise.

2700-3000 lb class engines for engines, with three of them. Weight of vehicle commensurate with that thrust. One of differences between Mark 1 and Mark 2 will be leading edges on nose for entry, but it’s a lot easier than orbit. Peak temp about 1200. Will use commercial for of RP-2.

Not four flight a day per pilot, but perhaps two. Methane interested for upper stages, not for suborbital.

Nice to be first in the marketplace, but better to be right. Multiple parties will be entering this market, and that’s great.

How far off is orbital flight? Can it scale up?

Orbital flight is where we want to go. selected this approach because it fits it a roadmap that leads there. That doesn’t mean that the vehicle design itself will carry over. It’s the systems concepts that will.

Does the vehicle require a sophisticated flight director? Jeff: A very sophisticated one, and he’s standing right here (referring to Searfoss). Very simple flight profile required to military vehicle, but expect the vehicle to be flyable by a pilot without a lot of need for automated flight control. Just took a dig at Scaled: “not like we’re going to just light off a hybrid rocket motor and we’re off on Mr. Toad’s Wild Right. “Digital throttle–on or off.” Throttling adds complexity and failure modees, and isn’t necessary.

How to reassure customers or investors that a cataclysmic failure by them or a competitor won’t destroy the industry? ME-163 bad example, but understand that safety has to be high priority. Never find anything in advance, will test, and test, and test. Will have more flights on it than anyone has put on a rocket vehicle before they put passengers in it. In a lot of ways the traveling public are a lot more sophisticated than people judging from the outside. Esther: If it’s inevitable, delay it as long as possible, set expectations properly, and realize that part of the appeal is that it is real. People die climbing Everest, often. Don’t make light of it, but doesn’t have to be a major blow to the industry.

Question to Esther: How important beyond military contracts and private travel, how much business beyond does she need. Not expecting asteroid mining or Mars colonization, but she expects them to develop this spacecraft and its descendants, but wouldn’t be surprised to develop new generations of technology and become part of the establishment. Not a long-term prospect. They are disruptive because they’re small and quick. Generating reasonable returns from the POV of a VC.
