战斗机发动机一直处于发动机技术的前沿。在第二次世界大战即将结束时,新问世的涡轮喷气发动机首先是在战斗机上取代活塞式发动机的。此后的半个世纪以来,战斗机发动机作为一些军事和经济强国的投资和开发重点,在技术上取得了巨大的进展。以战斗机发动机性能的主要性能指标推重比(发动机推力与发动机质量的重力之比)计,从40年代后期第一批实用的涡喷发动机的2～3提高到70年代的涡扇发动机的7～8,从而使战斗机的推重比从0.4提高到1.1左右,大大提高了飞机的速度和机动性,见图 Fighter engines have been at the forefront of engine technology. Towards the end of World War II, the newly launched turbojet engine first replaced the piston engine on a fighter plane. For half a century since then, fighter aircraft engines, as the focus of investment and development for some military and economic powerhouses, have made tremendous technological advances. Based on the thrust-to-weight ratio (the ratio of engine thrust to engine mass gravity) of the main performance indicators of fighter engine performance, from 2 ~ 3 of the first practical turbojet engines in the late 1940s to 7 ~ 8, so that the thrust of the fighter increased from 0.4 to about 1.1, greatly increasing the speed and mobility of aircraft, see figure
