| 中文摘要: |
| 在复杂电磁环境下， 飞行装备很容易受到电磁脉冲的干扰而偏离航线或坠毁。为了增加其抗干扰能力， 利用超宽带干扰源对飞行控制装备进行了强电磁脉冲效应试验。根据试验结果并利用电路检测和模拟仿真等办法， 得出了电磁脉冲干扰的作用机理， 共模电流和差模电压共同作用下使控制箱产生了令飞行器坠毁的畸变控制指令。针对干扰机理， 对飞行控制装备提出了 “软硬” 相结合的电磁防护措施。 |
| 英文摘要: |
| Under complex electromagnetic environment, flight equipment is likely to be disturbed by electromagnetic pulses, which causes flight route deviation or crash. In order to increase its immunity to electromagnetic pulses, the effect experiment of electromagnetic pulse on flight control equipment was carried out by UWS-HPM. Using the method of circuit check and analog simulation, the action mechanism of electromagnetic interference was drawn by experimental result. Under common-mode current and difference-mode voltage combined action, the control box deliver distorted control instruction that can make aircraft to crash. Aiming to the interference mechanism, the protection methods of flight control equipment was proposed by software and hardware combination. |
