摘要
通过分析EGT裕度对换发的影响和减推力起飞对发动机性能的影响,建立起减推力起飞的使用与换发之间的关系。EGT裕度衰退是航空公司制定换发计划的主要依据,减推力起飞可以延缓EGT裕度衰退的速度,采用减推力起飞对于减少因发动机性能衰退造成的换发具有积极的意义。
By analyzing the effect of EGT margin on engine removal and the impact of reduced thrust takeoff onengine performance,the relationship between reduced thrust takeoff and engine removal is established. EGT margin is the main basis for the airlines to plan for engine removal. Reduced thrust takeoff delays the rate of reductionof EGT margin and is positive to engine removal caused by engine performance deterioration.
