基于深入研究雷电电磁脉冲(Lightning electromagnetic pulse,LEMP)对飞行器的危害,提高飞行器雷电防护性能的目的。通过详细阐述雷电特性,分析影响飞行器在飞行过程中遭受雷击的主要因素,应用理论计算的方法,计算了雷电能量与飞行器的耦合,总结出雷电电磁脉冲对飞行器的危害效应。最后,主要从内部防护和外部防护两个方面,提出了飞行器LEMP防护方案。
Based on the in-depth study of the harm of LEMP to aircraft and the improvement of lightning protection performance of the aircraft, By elaborating the characteristics of thunder and lightning and analyzing the main factors affecting the aircraft during the flight, theoretical calculation method was used to calculate the coupling between thunder and lightning energy and the aircraft, and the harmful effects of thunder and lightning electromagnetic pulse on the aircraft were concluded. Finally, the LEMP protection scheme of the aircraft is proposed from two aspects of internal protection and external protection.
