本文的目的是描述一种适用于航空发动机机群在动态条件下工作的可靠性寿命预测方法。通过测量和记录某型航空发动机机群性能偏离正常工作状态的程度，建立了基于威布尔分布的机群性能可靠性模型。通过引入性能可靠性的概念，将可靠性与实际性能联系起来，得到了动态环境下发动机机群的平均寿命和性能可靠性控制方法。性能可靠性预测的在线、实时应用在运行控制和预测性维护中是有用的。
The purpose of this paper is to describe an approach to reliability life prediction, applicable to the aero-engine fleet, operation under dynamic conditions. The fleet performance reliability model based on Weibull distribution is established through measuring and recording the extent of deviation and degradation from a normal operating condition of aero engine fleet. The average life and performance reliability control method of the aero engine fleet are obtained under dynamic environment by introducing the concept of performance reliability which linked the reliability and actual performance. On-line, real-time applications of performance reliability prediction are useful in operation control as well as predictive maintenance.
