航空發動機（Aircraft engine）是指主要用來產生拉力或推力使飛機前進的發動機設備。除了產生前進力外，還可以為飛機上的用電設備提供電力，與為空調設備等用氣設備提供氣源。一般因為飛行的需求，設計都相當輕巧，但又要求相當的使用效能，以及極低的故障率，因而設計生產的工藝要求是比較高的。
Aircraft engines are engine equipment that is mainly used to generate pulling force or thrust to make the aircraft move forward. In addition to generating forward force, it can also provide electricity for electrical equipment on the aircraft and provide air for air conditioning equipment and other air-using equipment. Generally, due to the needs of flight, the design is quite light, but it also requires considerable performance and extremely low failure rate, so the design and production process requirements are relatively high.
