摘　　要：航空发动机是各种飞机的动力装置主要组成部分,被称为飞行器"心脏"。作为机械与电子高度融合的航空发动机,在使用过程中性能会出现不同程度的衰退。但如何方便快捷地计算出衰退的进程及其程度是很困难的。为解决这一难题,在性能衰退评估中采用排气温度这一单一参数,并建立其有关数学模型,简便有效地解决使用中的困惑。Aero-engine is the major component of the power unit of all kinds of aircrafts, and is called the ＂heart＂ of aircraft. Aeroengine highly integrates machinery and electronics, and its performance will decline in its service. But it is difficult to calculate the degradation process and degree. To solve this problem, the single parameter of exhaust temperature is used in the degradation evaluation and relevant mathematical model is established to solve the problems in a simple and effective way.
