Post Interesting concept...   Posted on: Wed Jul 13, 2005 8:46 am
The article "Bat Ship Begins" ( www.xprizenews.org/index.php?p=1008 ) obviously is talking about something like inflatable wings for a reusable suborbital first stage.

I already wondered last year if that is possible but thought my thoughts to be too vague to post them here. Currently that seems to be changing.

Would it be possible to use that wing-technology for renetering vehicles too? A modified CXV perhaps - which has the cooling of the actual CXV-design too but includes inflatable wings? If that's impossible - has that to do with speed then?

I hadn't thought about inflatable wings, but it's just crazy enough that it should work pretty well. I just wish I'd thought of it first.

Not inflatable - the SRBs on the side fold out and form the leading edges.

True, but the rigidity of the wing itself is due to the fact that it's pressurized. A.K.A. inflatable.

You would have had to have thought of it by the late 1950's. Inflatable re-entry vehicles have been on the drawing board for a *long* time; Goodyear proposed an inflatable craft for the Dyna Soar, and another company proposed inflatable wings much like the "bat ship" wings with a rigid leading edge & thin membrane, but with the leading edge being an inflatable structure, for recovery of Titan solids, individual crewman rescue, Saturn S-IC stage recovery, etc.

Glad to see you here Scott. For those of you that don't know him--he puts out the fine magazine APR which is on its last issue.

He is still doing good work, however. His website:

www.up-ship.com

Scroll all the way down and you will see his impressive resume. ATK is in good hands.

What about inflatability concepts different to that published by the initially listed article?

Tim Pickens from Orion Propulsion had a simliar idea a few years back, flyback booster, info does not seem to be on his website but I do remember watching a video about it.

www.orionpropulsion.com

it might be on youtube if someone has the time search......

Over at NewMars, in the Interplanetary Transportation section under Reentry we are discussing inflatables for reentry. Since 15% of the craft has to be heat shielding, it would cut the weight down a lot.
