有线控制飞行器群脉冲耦合效应及加固方法研究

飞行器在飞行状态时，控制导线在电快速瞬变脉冲群（EFT）作用下，该设备控制指令将会出现控制状态错误翻转、持续无指令输出等故障，产生故障的机理是电磁脉冲（EMP）通过传导方式进入控制箱产生紊乱的回输信号所致，严重时会损坏控制器及起飞装置。在实验基础上，研究了飞行器控制导线对电磁脉冲的防护加固方法，研究结果表明，对控制导线采取屏蔽法能够使飞行器对电磁脉冲具有很好的防护效果。

Coupling Effects of the EFT to Aircraft's Control Line and Protection Approaches

Control line is on the effect of EFT, aircraft control instruction state overturn wrongly or cannot be exported and so on when aircraft is flying. Mechanism of aircraft false control instruction false is that EMP coupling to aircraft＇s control line enters into control box by conduction and adds to information in- struction,making feedback signal out of order, so as to forming logic interference or physical damage to control circuit. Based on experiment, protection approach to control line has been researched in this paper. The research indicates that this approach of the shield is very effective for aircraft protection.
