Air/Kerosene Ambient air (78 % nitrogen, 21% oxygen, etc.) is scooped up by air intakes and used in turbojet, turbofan, ramjet, scramjet, or other airbreathing engines. It is used to burn aviation-grade kerosene, commercial grade JP-4 or JP-5, their military equivalents, or special high-temperature blends such as those used in the SR-71. More...
