摘　　要：讨论了RTCA-DO160第22部分“雷电感应瞬变敏感度”中雷电间接效应试验应力未覆盖实际电磁环境的问题。从飞机遭受雷电直击附着场景与飞机外部电磁场向内部传播的主要耦合机制、以及对金属或复合材料飞机内部设备产生的雷电间接效应——接口或电缆束上感应电压和电流等方面进行了分析论证,并且给出了优化建议。This paper discusses the problem that the lightning indirect effect test stress in RTCA-DO160 Part 22"lightning induced transient sensitivity"does not cover the actual electromagnetic environment.This paper analyzes and demonstrates the main coupling mechanism between the scene of direct lightning strike and the propagation of electromagnetic field from the outside of the aircraft to the inside,as well as the indirect lightning effect on the internal equipment of the metal or composite aircraft,i.e.the induced voltage and current on the interface or cable bundle,and gives some optimization suggestions.
