摘要
航空发动机故障诊断技术对避免飞行事故和降低飞行器运行成本是非常重要的。总结了航空发动机故障诊断的一些的方法,通过对各种方法的比较,对某种故障可以按照需要选择使用一种或几种方法。最后还介绍了目前较为前沿的两种故障诊断方法:小波分析法和神经网络法。
Fault diagnosis is great important for an aero - engine, not only to avoid the losses of human power and facilities , but also to reduce the mission cost . Some fault diagnosis technique for aero - engine are reviewed and some methods are very advanced in recent years. Compared those, one kind or many kind of methods can be adopted on need. Two main advanced methods are introduced briefly in the end, which are wavelet analysis and neural network.
