    If they want someone for ‘clean sheet’ development it seems more likely to be for the second stage engine for LauncherOne.

  2. 2 TB

    If they find one person who can do all that, he’s probably started his own rocket company already.

  3. 3 Doug Messier

    TB:

    That’s exactly right. There’s a preference for having this person as a Virgin employee as opposed to hiring someone with that type of experience on a contractor basis.

    Doug, do you think this means VG may have given up on the originally proposed composite rubber based engine similar to what Scaled used in Spaceship 1? And how far do you think this might potentially put them back? Four years perhaps?… Purely speculative questioning here of course!

    Greg -

    Scaled has not given up on the Hybrid Rocket Motor for SpaceShipTwo. That isn’t to say the development process hasn’t been without its difficulties but most of the problems are due to the sheer scale of the motor. Very few have ever pursued a hybrid of this size because those with the funding were generally government agencies with an interest in orbital flight which hybrid motors simply lack the specific impulse to achieve.

    The oxidizer tank accident was a huge hit to Scaled and the Scaled family. They recovered from that and contrary to the, in my opinion at least, ridiculous amount of speculation that has gone on regarding the rocket’s development, neither company has given up on the hybrid motor.

    Scaled and SpaceDev have pushed major boundaries with this motor. There are plenty of achievements and successes in its development the world will never know. As liquid reliability and simplicity continue to evolve, it may be replaced with such an engine. Until then, both companies are committed to the concept and aren’t continuing development under duress.

    I realize this was a longer post than you bargained for, and I’m not Doug. However, I’m consistently amazed at the amount of irresponsible speculation on RocketMotorTwo I see as I travel the web. Not so much here but reading other blogs, you’d think Scaled won’t ever light SS2′s candle.

    Greg:

    Virgin is developing liquid engines for LauncherOne (air-launched from WK2) and is also one of six funded companies under DARPA’s ALASA program (air launching 100 lb. payloads into orbit for under $1 million). Last summer, Stephen Attenborough told Aviation Week that the liquid engine would eventually replace the hybrids. But, that is some years away. So, that’s part of the reason for hiring so many engineers, but it’s not the full story.

    Winglet is right. Scaled and VG remain wedded — for better or worse, depending on who you talk with — to using a hybrid motor for SpaceShipTwo for the foreseeable future. However, it is not necessarily the hybrid motor that Sierra Nevada has been working on. Alternatives are being developed and tested. What all that means for the flight test and commercial operations is unknown at this point.

    Thanks Winglet and Doug for the comprehensive replies! Interesting that VG are exploring other hybrid options than Scaled’s offering, but I guess its sensible to leave your options open! Please accept my apologies for the speculative Q,I only meant it with a twinkle in my eye and certainly do not want to contribute to unhelpful gossiping!! In this context, I just wish Mr Branson had not created this rod for his back with the seemingly constant 4 year target to first commercial launch… Im sure that VG and Scaled will eventually get there, and safely too! :-)

    My comments were in no way intended to be directed at you, or Doug for that matter. I’m sorry if either of you took them that way.

    I am very close to these projects and therefore know quite a bit about what goes on behind the black curtain. What bothers me is modern flame/link-bait “journalism” where bloggers and others who should know better post conclusions without any basis in fact. Often, the author has no direct knowledge even on the topic, yet he or she is commenting on why the SS2 did this or why WK2 did that, or why the oxidizer explosion occurred, etc. The fact is, Scaled and VG release very little about their program and without knowing more, people shouldn’t be posting speculation as fact. Which is all too common.

    I visit this blog because I generally don’t see that and it’s refreshing. Plus I hate the US Congress so I enjoy a good Doug-rant on that.

    Back on the topic… Virgin isn’t exploring alternative hybrid options to Scaled’s offering. They are exploring liquid motors for LauncherOne and possibly for future use in SS2. Bear in mind that Scaled did not know how difficult it would be to “scale up” the SS1 motor. They’ve hit a number of physics boundaries that have made it quite difficult. Large hybrids suffer from combustion stability, structural, and fuel regression challenges. Scaled and SpaceDev have really had to innovate to get the motor to work as well as it does. As well, suppliers of things like injector nozzles, mating flanges, etc. aren’t everywhere as hybrid motors are rare and mostly unexplored as compared to liquids and solids. Therefore, manufacturing is even a challenge.

    The SS2 program may be way behind the originally published “schedule” from VG but it is right where Scaled wants it. Safe, simple, strong, efficient, and understood by engineering. They aren’t happy it’s taken as long as it has but that’s been the hallmark of Burt’s career and the culture he built. He doesn’t announce schedules.

    SpaceShipOne was 1.5 years behind “schedule” when it flew the X2 flight. And no one knew, because there never was a schedule to know.

    I stand behind my earlier statement. There are alternatives to the Sierra Nevada hybrid under development. And they have been tested in Mojave.

    Note: Reply corrected. Originally wrote Scaled Composites instead of Sierra Nevada.
