摘　　要：针对某型航空发动机空中自动停车故障诊断中故障症状与故障原因之间关系极为复杂、不确定等问题,提出了该型发动机故障的模糊诊断方法,建立了发动机自动停车故障模糊诊断的数值理论模型,利用专家知识动态建立了模糊诊断矩阵过程模型,并结合具体自动停车故障案例,实现了该型发动机自动停车故障的模糊诊断。To solve the problems in the diagnosis of automatic shutdown faults of certain aeroengine, such as the complex relationship between the phenomenon of faults and the causes for the faults, a diagnosis method of the automatic shutdown faults of aeroengine based on fuzzy diagnosis theory has been proposed, and the numerical theoretical model has been built. Using the practical knowledge, the matrix procedural model based on fuzzy diagnosis theory has been established. Case studies show that this method can diagnosis the automatic shutdown faults ofaeroengine with high accuracy.
