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...

Very interesting indeed. Thanks Hesham!hesham said:The Northrop Grumman RLV,notice the six-engined flying wing
