| Abstract: | Fault tree analysis （FTA） is a widely -used method for failure analysis and fault diagnosis. Combining with APU＇ s working characters, the author analyzes the causes of starting difficukies, builds APU starting difficulty fault tree, and also gives a qualitative and quantitative analysis of basic causes of fault tree. It finally points out the APU fault suggestions to predict and prevent failure occurring. |
