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、１个机动飞行类和１个高频疲劳考核谱 According to the flight mission profile of the trainer engine, two spectrum comprehensive mission profiles and two maneuver flight comprehensive mission profiles were developed. Then according to the life-span analysis results of the main components of the engine, the comprehensive task spectrum is compressed under the condition of equal damage, and the test spectrum of the acceleration task is compiled, including: 2 routes, 1 maneuver and 1 high Frequency fatigue assessment spectrum
