简介:摘要 飞机地面试车时发现,当发动机在引气结束之后进行关闭引气时,过程中出现发动机未操作异常停车故障。因此本文针对发动机关闭引气异常停车事件,结合发动机及相关控制部件系统结构及工作原理,通过采用故障树的方式进行逐项排查,最终定位发动机关闭引气异常停车故障的直接原因是引气关闭逻辑命令采用风门关闭信号间接代替,未使用进气门真实状态信号。

简介:摘要:在航空飞机的运转中,各个部件的系统都会相互协作,并起到协同工作的效果,而发动机引气系统则是最为重要的一环,它的主要职责和功能是为航空飞机的气源系统提供压力、温度调节的压缩空气,一旦引擎的引气系统发生了问题,那么飞机的正常运转就不能正常运转,而且在飞行的时候,还会对旅客的生命安全构成威胁,引起极大的恐惧,甚至会引起更大的后果。所以,有必要对飞机发动机引气系统展开一次全方位的剖析,弄清楚造成系统问题的主要因素,并做好相应的调查,以便能够及时地对飞机的发动机引气系统进行维修与管理,尽可能地减少故障的发生,以免对飞行的效率与品质造成不利等后果。本文先介绍了飞机发动机引气系统发生故障的原因,然后再分析了飞机发动机引气系统的常见故障与维护措施,希望有一定的借鉴价值。
