Associated Launch Vehicles
X-30 American SSTO winged orbital launch vehicle. Air-breathing scramjet single stage to orbit. Second attempt after study of similar proposal in early 1960's. Cancelled due to cost, technical challenges. More...
Air/Slush LH2 Ambient air (78 % nitrogen, 21% oxygen, etc.) is scooped up by air intakes and used in turbojet, turbofan, ramjet, scramjet, or other airbreathing engines as an oxidiser. Slush hydrogen is formed by taking liquid hydrogen down to nearly the melting point. This produces a partly-solidified but still mobile version of the fuel with 20% greater density than liquid hydrogen itself. Proposed for use from the 1980's in air-breathing and rocket-powered single-stage-to-orbit vehicles where maximization of fuel weight to empty weight is absolutely essential. More...
