air-breathing

[′er ′brēth·iŋ]
(mechanical engineering)
Of an engine or aerodynamic vehicle, required to take in air for the purpose of combustion.

air-breathing

An engine that sustains its combustion by using oxygen from the incoming air. Both reciprocating and gas turbine engines are air-breathing, whereas a rocket carries its own oxygen and, hence, is not an air-breathing engine.
