摘要: 提出了一种航空发动机性能差异问题的故障部件快速检验方法.该方法以部件特性曲线为基础,可以快速检测出航空发动机各部件的自身特性变化而排除由于其它部件性能变化引起的工作线变动带来的影响,从而快速判断出故障的部件.该方法特别适用于仿制发动机与原型发动机性能变化原因的查找.

Abstract: A simple fault diagnosis method for aeroengine's performance was developed.Based on component characteristics,this method could detect quickly the inherent change of aeroengine's components and judge the faulty components.Meanwhile,the fault influence of other component can be removed.This method is particularly suitable for finding out aeroengine performance changes between copying engine and typical engine.
