摘要
在大量的外场统计和空测的基础上，对某教练机发动机的外场使用载荷进行了分析研究，得出其转速次循环服从威布尔分布，并计算了其分布的密度函数。
A full-scale statistical analysis of working loads has been made on the basis of a great number of data collected from real measurements in flying tests of trainers and a large number of data collected from actual service practice.It is found that the frequency distribution of the partial rotaional speed cycles in the trainer engine accords with Weibulll Distributon.The results provide a basis for the engine fatigue test,life analysis and design of duty cycles for a new trainer engine.
