摘要
某型发动机在飞行试验台上进行空中起动过程中发生了排气温度过高、转速"热悬挂"的现象,介绍了其故障现象,详细分析了相关参数,发现其原因是在发动机起动中没有进行供油高空修正,引发燃油量过大,导致发动机排气温度过高。
The failure of high exhaust gas temperature and hot suspension rotor speed occurred in airstart process on an aeroengine flight test bed.The relevant parameters of the failure were analyzed in detail.The failure reason was found that the fuel supply high-altitude correction was not conducted in the engine start process,leading to large fuel quantity and high exhaust gas temperature.
