飞控设备抗强电磁脉冲方法研究

Protecting Method Investigation of Resistance Against Strong Electromagnetic Pulse for Flyight Control Equipments

强电磁脉冲可引起空间飞行器的控制设备发生瞬时或永久故障,从而导致飞行失控。针对强电磁脉冲环境下飞控设备的防护问题,首先分析了强电磁脉冲对飞控设备的损伤效应,其次探讨了相关的防护方法,并给出了屏蔽效能和整机防护试验验证的测试结果,为提高飞控设备抗强电磁脉冲能力建立基础。

Strong electromagnetic pulse can cause instantaneous or permanent failure of aircraft con- trol equipments and lead to flight out of control. Aiming at the protecting problems of flying control equip- ments under strong electromagnetic pulse environment, hurt effects of flying control equipments from strong electromagnetic pulse are firstly analyzed, then the relevant protecting methods are investigated, and lastly the test results of shield performance and guard trial verification are presented, which helps to build groundwork for raising the ability of resistance against strong electromagnetic pulse for flying con- trol.
