在分析飞机活塞发动机结构特点的基础上,根据外场维修经验及系统故障汇总分析,建立了活塞发动机故障树,并对故障树的逻辑关系和定性分析进行了研究。实践证明,该方法很好的提高了发动机故障诊断和排故效率。
Based on the analysis of structural characteristics of aircraft piston engine, the fault tree of piston engine is established according to the field maintenance experience and the summary of system faults. The logical relationship and qualitative analysis of the fault tree are also studied. Practice has proved that this method can well improve the engine fault diagnosis and troubleshooting efficiency.
