Thanks for the replies all!
This one I don't follow. The actuators on swept wing aircraft don't make them impractical. If there's some non-linear factor in scaling that up to the shuttle I don't see it. Also Im proposing to lose the heat shield weight by the time the wings deploy - so perhaps that counters the actuator weight a bit.
Yes that might be show stopper.
Why does there need to be any fluid flow during storage? I would think only during deploy and only then if you went hydraulic vs electric.
Well that supports my point. I want to totally remove the aerial surfaces from ascent and max Q. That implies a much reduced drag coefficient on ascent and thus some substantial (?) savings in fuel. From Wiki
Well of course in general a re-entry vehicle historically does not need wings to slow it down, it only needs blunt body
drag to slow it down as has been done in the past with Apollo et al. The shuttle happens to use its wings for that purpose in a series of high G turns.
Yes, I'm suggesting wing storage does away some significant contributors to that complexity: that fragile, tile based heat shield which must be seen as an Achilles heal of the current design; I read now that management of the surface foam on ascent (which killed Columbia) is problematic - requiring telescopic inspection of the shuttle in orbit, etc, etc. A stored wing does away with all of that and use a traditional monolithic heat shield as has been done in the past.
Likely so, though thats not clear to me. I was thinking the wings we be scissored, overlapped for storage underneath the fuselage.
Yes, but there's experience w/ swept wing mechanicals and I'm proposing elimnation of much more complexity in return, I believe.
Not if they don't deploy until late into re-entry. I suggest deployment a little higher than when the shoots popped on capsule re-entries.
Yes exactly, replace all of that a single monolithic shield. Eject the shield as done w/ capsules exposing deployable wings.
