為什么是不同型式的發動機此二型發動機有何不同，各有何特點當前常用的還有哪些發動機渦輪噴氣發動機渦輪風扇發動機

渦輪風扇發動機低涵道比渦輪風扇發動機高涵道比渦輪風扇發動機加力式渦輪風扇發動機低涵道比渦輪風扇發動機

20世紀60年代，廣泛用于窄體機身的旅客機，如三叉戟，波音707，波音727、波音737-200，MD-80，圖-154等。三叉戟波音-707

高涵道比渦輪風扇發動機上世紀70年代初投入使用后，已廣泛用于各種類型的旅客機包括干線客機、支線客機。加力式渦輪風扇發動機自上世紀60年代研制成功后，已成為現代戰斗機的動力裝置，并促進了第3代、第4代戰斗機的發展除渦輪噴氣、渦輪風扇發動機
