air-breathing
Needs atmospheric gas
Air-breathing describes engines or organisms that take in atmospheric air.
An air-breathing engine, like a jet, uses oxygen from the surrounding air for combustion, unlike a rocket that carries its own oxidizer.
The term distinguishes such systems from those designed for environments without atmosphere: air-breathing missiles, air-breathing fish that surface periodically.
