航空发动机晶体管式点火系统火花频率稳定性研究

摘要

In order to improve the spark frequency stability of aeroengine transistor ignition system,working principle of the transistor ignition system is analyzed. The factors that affect spark frequency stability were found out. The voltage compensa⁃tion and temperature compensation were adopted for the influence factors. The spark frequency comparison experiment was per⁃formed. In the case of high temperature and voltage fluctuation,the spark frequency stability of the compensated ignition system is increased by a factor of about 50%.%　　为了提高航空发动机晶体管式点火系统火花频率的稳定性，通过电路原理分析，找出影响火花频率稳定性的因素，进而采取电压补偿和温度补偿，并做了补偿前后火花频率对比测试。在高低温及电压波动情况下，补偿后的点火系统输出的火花频率稳定性提高了50%左右。
