教练机发动机加速任务试车谱的编制

FORMULATION OF A TRAINER ENGINE ACCELERATED TEST SPECTRUM

根据教练机发动机的飞行任务剖面，研究出２个航线类综合任务谱和２个机动飞行类综合任务谱。然后根据该发动机主要零部件的寿命分析结果，在等损伤的前提下对综合任务谱进行压缩处理，编制了其加速任务试车谱，包括：２个航线类。

Two composite rise and fall mission profiles and two composite maneuver flight mission profiles are obtained from the initial design missions of a trainer engine.These composite missions are accelerated according to life analysis of engine main components under the condition of equivalent damage.The accelerated mission test spectra include two rise and fall profiles,a maneuver profile and a high cycle fatigue test spectrum.
