that one in Langley WT
other clues are
According to Hypersonic Revolution Vol.III by Larry Schweikart -
Two Boeing design studies were completed, one was 'winged body', so-called government baseline, i.e. scaled-up duPont design, so basically all published illustrations if refered to this study is not far away from truth.
Later Boenig shifted to Langley-promoted (sic!) conical accelerator, but entered a serious problems as result was VERY long vehicle with myriad stability/engine control problems. Boeing was downselected from competition.
OK I thought after I posted that you may have meant that escape
capsule design vehicle. That design looks like it may block some of the
inlet flow on the top of the vehicle at positive angles of attack.
Not sure how serious that design was or whether it was just something
to show to work out the escape capsule idea.
Flateric, there have been A LOT of conical hypersonic vehicles
that have been analyzed.
Besides the ones you mentioned, a few more that come to mind:
- Tony Ferri's famous conical design he proposed with thermal compression
and held up by his GASL guys during NASP as something to look at.
- At least two (maybe a few more) from Republic that I have that are not
in a good enough form to share.
- NASA Langley's RBCC Generic Accelerator Wind Tunnel model that Bill Escher
talks about in some of his RBCC papers.
- Bill Escher's Synerjet
- USAF cone shaped vehicle in Sweetman's Aurora book shown taking off (concept).
It's like from USAF XD Dept. or something like that, at Wright Patterson.
I'm sure there are many more.
I agree it would be nice to know what the actual NASP contractor proposals
were, but when I read "Hypersonic Revolution", first, it's like a program
management book, not a technical book, and the feeling I'm left with
is that nobody knew what to build and that there was a lot of posturing.
To build this bird you don't throw billions at it, make an impossible goal,
and give it to airframe and engine companies who don't believe in it because
the textbook on how to do it isn't on their shelves. You give some resources
to the guys that are passionate about it and have done the work on it up to
that point. You assign an airframe and engine contractor to offer advice. But
basically get out of the f----- way! Would you have gone SSTO? Probably not,
but you would have gotten to mid-teens Mach with a few research vehicles.
And that would have been AWESOME !!
