摘　　要：雷电对飞机的飞行安全构成严重威胁,机载天线作为飞机的外部突出的结构件,较易成为雷击附着点。当闪电击中天线时,与天线相连的电缆一端可能产生短时的电压瞬态,并且造成元件故障及设备误动作和损坏。采用电磁仿真与实验相结合的方式,对飞机雷电实验中的“外部安装硬件的注入瞬态试验”方法进行了研究,分析了机载天线由于雷电流附着而被注入电压电流时,其与飞机组件相连的导线中的诱导电压和电流。该项工作为进一步开展飞机外部结构件的雷电效应研究及机载设备的雷电防护研究提供了一定的基础。Lightning poses a serious threat to the flight safety of aircraft. Airborne antenna, as an external structure of aircraft, is probably to become a lightning attachment point. When the antenna is struck by lightning, the end of the cable connected to the antenna may produce a short time voltage transient, and cause component failure or equipment malfunction and damage. Based on the method of combining electromagnetic simulation and experiment, the aircraft lightning indirect test of ＂induced transients in external mounted hardware＂ is studied in this paper. The induced voltage and current in the cable which is connected with the airplane components are analyzed. The work provides a basis for further research on lightning effect of aircraft external structure and lightning protection of airborne equipment.
