某型航空发动机空中降转故障分析

Analysis of Inflight Speed Drop Failure for an Aeroengine

针对某型航空发动机空中降转故障,从改变燃油流量调节器的供油特性方面分析其发生的主要原因,提出了核心排故途径,即改变膜盒组件相关设计参数。

Aiming at the inflight speed drop failure of an aeroengine,the main failure factor was analyzed by changing the fuel supply characteristic of fuel flow regulator.The change of relevant design parameters for the capsule assembly is the core approach for eliminating the failure.
