某型飞机起动机误起动故障分析和报警电路研制

Analysis of Light Aircraft Starter Mistakenly Starting Faults and Development Warning Circuit

针对某型飞机地面测试中连续发生的多起起动机误起动的故障,分析并查找出了起动机继电器粘连的故障原因。按照航空器加改装设备的要求进行报警电路设计研制和测试。装机试验表明,该电路能够实现对粘连的起动机继电器进行自动报警,具有推广、应用价值。

For the several starter mistakenly starting faults of the light aircraft in the ground test,the reason of starting relay adhesion was checked out. The early warning circuit according to the rules of the aircraft addition and modification was developed and tested. The installing experiments were completed which verifies that the circuit is able to alarm automatically for the starting relay adhesion, and has a good application value.
