点火系统不同储能下点火频率稳定性研究

Ignition Frequency Stability of Ignition System with Different Stored Energy

发动机点火系统一般由点火装置、接触装置、半导体电嘴组成。现行军用飞机由于功能不同,发动机的结构及运行方式亦不同,所以发动机配置的点火系统点火频率及火花能量都不同。基于某型航空发动机的点火系统,研究其在不同储能下点火频率的稳定性,为其他型号航空发动机点火系统设计研发提供依据。

The ignition system of an engine is composed of an ignition device,an ignition cable and a semiconductor igniter in a general way.Due to different functions,the structure and operating mode of engines are also different,so the ignition frequencies and spark energy of ignition system in the engine are different.In this paper,the ignition frequency stability of the ignition system of a certain type of aircraft engine with different energy storage is studied,to provide the basis for the study on other types of aviation engine ignition systems.
