Air-Breathing Rocket Engine

Air-Breathing Rocket Engine

 

a combined reaction engine in which the cycles of an air-breathing jet engine and a rocket engine take place. It may be used in astronautics for space shuttles. The term is sometimes used to denote an engine in which the oxidizer is atmospheric air liquefied in flight; this hypothetical type of engine has been proposed for prolonged flight in the upper atmosphere.
