Gas turbine engines are widely used in the fields of air,ground and ship,so it is much of importance to assess engine performance and diagnose its faults.This paper surveys the development of engine fault diagnosis and the main diagnosing methods including gas path analysis,non-linear mode methods and artificial intelligence methods.Finally,the prospect of studying engine fault diagnosis is presented.
