减推力起飞对航空发动机性能影响

Impact of Reduced Thrust Takeoff on Aero Engine Performance

介绍了飞机减推力起飞的方法,分析了减推力起飞对民用涡轮风扇发动机性能的影响。得出减推力起飞能降低发动机涡轮前温度、起飞排气温度裕度(EGTM),延长发动机在翼时间和使用维护周期,达到节约发动机维修成本的目的。

This paper introduces the methods of reduced thrust takeoff of airplanes,and analyses the influence of reduced thrust takeoff on the performance of civil turbofan engine.Conclusion is that reduced thrust takeoff can reduce engine turbine temperature and the takeoff exhaust gas temperature margin（EGTM）,and prolong the time of engine in service and the working cycle,to achieve the goal of engine maintenance cost saving.
