slotperfect 7 #1 August 27, 2002 I met this guy at Symposium in Jan '01 in San Diego. He's not nuts . . . just really ballsy and extremely smart in a mechanically creative sort of way.

PhreeZone 20 #2 August 27, 2002 I spent 20 minutes on the site reading and if the Air pistons fire right and the fins work... the trials to 15000 might actually work... it think it will need more fuel then his calculations though...Yesterday is history And tomorrow is a mystery Parachutemanuals.com Quote Share this post Link to post Share on other sites

I've seen similar designs on other booster proposals, and they're often a band-aid for a poor propellant ratio. In addition, the recovery system, as far as I can tell, has four deployment stages - and they have to function from vacuum to 15psi. That's more complex than any other vehicle I know of; even more complex than the X-38, the proposed (and now cancelled) ISS escape vehicle. They actually did some drop tests with the X-38 and discovered problems with the ram-air. (Bill Gargano worked on the system; for some really cool pics check out http://www.dfrc.nasa.gov/gallery/photo/X-38/) I have no doubt you could make all this work, but I'd be very curious as to how much all the drop testing would cost. Another alternative would be to use something like an F-111 escape module (http://www.fb-111a.net/Module.html) which is already designed for the purpose, and are easy to come by.
