Hi,

here is a shuttle concept using detachable turbojet.

Is this Starraker?
No. That's one of the numerous variations on the NASA-Langley "Spacejet" concept. Separate flyback jet "pods" beneath a large spaceplane.

Re: NASA Langley SpaceJet Concept

...Jeez, Hesham! Rotate your images next time. Damn near sprained my neck trying to figure out which way to view that one! :eek: :eek: :eek:

Re: NASA Langley SpaceJet Concept

Interesting that they experimented with two separate engines both with flyback capability, versus a single integrated twin engine configuration. I would think a single twin engine would have provided a simpler more elegant solution, without the risk of the two engines colliding during the detachment/separation phase.

Re: NASA Langley SpaceJet Concept

There's a 1981 SpaceJet paper in the NASA archives:

[quote author=http://ntrs.nasa.gov/search.jsp?R=264007&id=1&as=false&or=true&qs=Ntt%3DSpacejet%26Ntk%3Dall%26Ntx%3Dmode%2Bmatchall%26Ns%3DHarvestDate%257c1%26N%3D0]
Title: Aerodynamic tests and analysis of a turbojet-boosted launch vehicle concept (spacejet) over a Mach number range of 1.50 to 2.86
Author(s): Riebe, G. D.; Small, W. J.; Morris, O. A.
Abstract: Results from analytical and experimental studies of the aerodynamic characteristics of a turbojet-boosted launch vehicle concept through a Mach number range of 1.50 to 2.86 are presented. The vehicle consists of a winged orbiter utilizing an area-ruled axisymmetric body and two winged turbojet boosters mounted underneath the orbiter wing. Drag characteristics near zero lift were of prime interest. Force measurements and flow visualization techniques were employed. Estimates from wave drag theory, supersonic lifting surface theory, and impact theory are compared with data and indicate the ability of these theories to adequately predict the aerodynamic characteristics of the vehicle. Despite the existence of multiple wings and bodies in close proximity to each other, no large scale effects of boundary layer separation on drag or lift could be discerned. Total drag levels were, however, sensitive to booster locations.

Actually, more like *eight* engines, four per pod. Varied from concept to concept though.

Thanks for that. How does this compare to the Stratolaunch concept? You would think a small shuttle-like craft such as the Sierra Nevada Dreamchaser could be used as the reusable upper stage for it.

Hi,


I don't know this concept,may be from North American.

no not a spaceJet nor NAA
but something more interesting: a early Boeing Dyna Soar reusable Booster !
were have you found this, Hesham ?

Thank you Clark,


and for the Boeing Dyna Soar picture,I will send it in its topic.

Reminds me of the RASV concept.
Uhm, Moonbat? The first pic reads "Reusable Aerodynamic Space Vehicle" (RASV) :)

Ah, million thanks. I perfectly know the wayback machine but tried finding this forum very page from 2012. Didn't worked. I will remember that trick. Thank you again.

come on, was my post kind of *censored* ? (shake his head in disbelief) ok, swearing, vs politically correct and sensitive ears (rolls his eyes).

Let's say Frank Wolf was a very annoying naughty boy on the whole case. And yes, the chinese spy he witch-hunted had porn in his laptop, not NASA "secrets". Hey, that's how thing happened, in April 2013.
Just ask Keith Cowing at NASAwatch, he still furious about it.

"Feasibility Study of Reusable Aerodynamic Space Vehicle" SAMSO report, 1977

Is that report classified ?

And it all came from this project. Amazing..... https://en.wikipedia.org/wiki/Zero-X
Well it's not a bad start at least though it could definatly use some trimming of the complexity :) LIke "ZeroX" the SpaceJet idea was to reduce the booster 'aircraft' to a minimum while using the more robust spaceplane wings for most of the lift. Trying to 're-rendezvous' with the "Lifting Bodies" and super/hypersonic speeds never made a great deal of sense to me as shown in the movie itself :)

Yes. However, *perhaps* not for much longer. I have a FOIA request in for the two volumes; both "SECRET," but both being passed along to the controlling authority for review. From previous experience, this means that I could get copies in my eager little paws in a matter of weeks, a couple years... or never. Stay tuned.

I would pay whatever sum of money required to get my hands on these reports, really.

Latest FOIA update: not two volumes but four, being passed along to the controlling facility for review and *hopeful* declassification and shipment.

Vol. 1: Executive Summary
Vol. 1: Reusable Aerodynamic Space Vehicle Systems Design & Analysis
Vol. 2: Vehicle design & Analysis
Vol. 3: Appendices

Why are there two Volume 1's? Dunno. What's the difference between Vol 1 and Vol 2? Dunno.
