某型发动机限温系统调节品质对其工作的影响

Impact of the Regulation Quality of Temperature Limiter System on a Certain Type of Engine

采用两种不同型号的温度限制器配装某型发动机进行飞行试验。试验时,其中一台发动机出现了空中停车。通过对试验数据的分析,结合温度限制器的工作原理,明确了发动机停车原因,给出了解决措施,并进行了地面及飞行验证试验。通过本次试验,可以为发动机的研制及外场排故提供参考。

Two different temperature limiters are adopted to configure a certain type of engine, then, the flight test is conducted. During the flight test, flameout occurred in one of the engines. Based on the analysis of the experimental data and the operating principle of temperature limiter, the causes that result in the engine flameout are identified, and the solutions are proposed. Then, the ground test and the verification test are conducted successfully. This flight test could provide reference for the engine development as well as field troubleshooting.
