Sabre Rolls Royce air augmented rocket engine. Used Air/Lox/LH2. Developed -1995. Isp=700s. In development for Skylon launch vehicl; descendent of RB545 developed for abandoned HOTOL space launcher. More...
Air/Lox/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. In this variant the motor converts to pure rocket propulsion, using on-board liquid oxygen for the final push to orbit. More...
