An engine used to generate the power required for an aircraft to fly or soar. It is an internal combustion engine that utilizes the heat of combustion of fuel. There are two types of aircraft engines: shaft-powered engines, such as piston engines and turboprop engines, which extract power in the form of shaft power, and jet-powered engines (so-called jet engines), such as turbojet engines and turbofan engines, which draw air from the front and expel it to the rear as a high-speed jet, and extract power in the form of the increased kinetic energy that occurs when this happens.

航空機が飛行あるいは浮揚するのに必要な動力を発生するのに用いられるエンジン。燃料の燃焼熱を利用する内燃式熱機関である。航空エンジンには,ピストンエンジンやターボプロップエンジンのように動力を軸動力の形でとり出す軸出力型エンジンと,ターボジェットエンジンやターボファンエンジンのように前方から吸い込んだ空気を後方へ高速の噴流として噴出し,その際の運動エネルギーの増加の形で動力をとり出すジェット出力型エンジン(いわゆるジェットエンジン)がある。
