Hi,

I know my dear Flateric spoke before about it,but here is from Flightglobal.

Never spoke about this. And - this is again *artist fantasy*
 
http://www.secretprojects.co.uk/forum/index.php/topic,953.msg8351/highlight,rlv.html#msg8351
 
And where's a mention of *that* stuff at the thread of organizing files/papers that you've provided?
Once more - this is truly fantasy picture that every aerospace engineer will laugh of - especially regarding weird orbiter's wing.
 
Hi,

and the NASA RLV.

Looks a lot like the old German Saenger TSTO.

http://www.spacefuture.com/archive/how_much_new_technology_is_required_for_future_reusable_launch_systems.shtml
(About halfway down the page.)

Also, here's a very lengthy page concerning the Blackstar TSTO and some discussion in the thread concerning borane fuel(s) that the Blackstar was rumored to burn on it's way to supersonic flight or orbit.
It might be informative and related to this thread as a TSTO.

Blackstar, if it existed, wasn't a NASA project as such, but Aviation Week set the record straight by publishing what information they were able to compile.

This is Andrew Space and Technology Griffon.

A TSTO using air liquefaction, and LH2 fuelled turbofans.

If I remember my Air&Cosmos readings... the first stage has a rocket engine and turbofans; both burns LH2.

Turbofans use air as oxidizer, while the rocket engine need LOX.

this TSTO take off from the Cape, and fly toward the equator for 6 hours. During this time, the turbofans suck air in the atmosphere; and part of this air is converted into LOX for the rocket via a LACE system call "Alchemist".

After 6 hours, LOX tank are full, so the first stage light its rocket engine and climb to 60km and mach 6 to delivers an expendable upper stage or an internal tank orbiter.

Voila!

(any information on the "alchemist" would be welcome...

ood, a Boeing (former Rockwell x-33 proposal) SSTO carry a X-37 on his back...
 
Actually, the carrier stage in this illustration is a derived version of the McDonnell Douglas Delta Clipper. Rockwell had the most 'conventional' design on the X-33 competition, a classical wing body configuration with a cylindrical fuselage with circular cross section.

Hi,

here is two Boeing TSTO RLVs,one with propellant crossfeed and the
other haven't.

Better late than never I suppose... an interesting one this Alchemist:

I remember the alchemist from the SLI days.

Andrews Space is a Boeing Seattle space offshoot, no?

Founded in 1999 and they quickly got NASA contracts. Seems quite quiet at the moment though. They got Kistler work that didn't turn out well, they also lost with their COTS proposal.

Dr. Dana Andrews, Chief Technology Officer
Dr. Dana Andrews joined Andrews Space as Chief Technology Officer. Prior to joining Andrews Space, Dr. Andrews worked at The Boeing Company as Director of Reusable Launch Systems for Boeing Phantom Works, where he oversaw the Boeing TSTO RLV, Future X, Military Space Plane, and Solar-Thermal Orbital Transfer Vehicle (SOTV) Programs. He was Chief Engineer for the Boeing side of the McDonnell/Boeing team for the X-33/RLV program. He also managed the Boeing Air-Launch Studies, and initiated and led the Boeing team for the Commercial Space Transportation Study (CSTS). Prior to that Dr. Andrews was Program Manager for the BMDO SSTO Study, Functional Manager of Aerodynamics for the Boeing Aerospace Group, Boeing Habitation module Manager for the International Space Station Program, and Program Manager for the Aero-Assisted Orbital Transfer Vehicle (AOTV).

Very interesting indeed. Thanks Hesham!
Is there more information available elsewhere on this NG RLV/flying wing project?
