民机发动机灭火剂浓度测量适航审定试飞方法研究

Study on Test Flight Method of Airworthiness Certification for Civil Aircraft Engine fire Extinguishing Agent Concentration Measurement

发动机为火区,有着火风险,可能导致严重的事故。文章通过介绍发动机灭火剂浓度测量试验要求、验证方法、灭火剂喷射预定温度选择、飞行试验方法,为今后民用飞机机型顺利通过发动机灭火剂浓度测量试验提供参考。

The motive is fire zone, which may cause serious accident. This paper introduces the test requirements, verification methods, pre-determined temperature selection and flight test methods of engine fire extinguishing agent concentration measurement, and provides reference for future civil aircraft to pass the test of engine fire extinguishing agent concentration measurement.
