当代战斗机动力装置大致可以分为两个推力级,一个是69～88千牛(7～9吨力)推力级,另一个是118千牛(12吨力)以上推力级。前者适于装中型双发战斗机或单发轻型战斗机,后者则适于装大型双发战斗机及相对轻型的单发战斗机/轰炸机。从发动机循环参数来看,当代战斗机动力装置大多是双转子低涵道比涡扇发动机。这样的结构带来的好处是:飞机在亚音速巡航状态,发动机不开加力的单位耗油率(sfc)很低;作跨音速飞行时,发动机不开加力也能提供大推力,可提
Contemporary fighter power units can be broadly divided into two thrust stages, one with a thrust of 69-88 kN (7-9 tonne) and one with a thrust of 118 kN (12 tonne). The former is suitable for medium double fighter or single light fighter, while the latter is suitable for large fighters and relatively light single fighter / bomber. From the engine cycle parameters, the contemporary fighter power plant are mostly dual rotor low bypass ratio turbofan engine. The benefits of such a structure are: the aircraft in subsonic cruise, the engine does not open the unit of the fuel consumption rate (sfc) is very low; for transonic speed flight, the engine does not open the force can provide a large thrust can be mentioned
