雷击直接威胁飞行器的飞行安全,基于深入研究雷电电磁脉冲(LEMP)对飞行器的雷击特性,提高飞行器雷电防护性能的目的。文章应用一种静电场分析的方法,利用CST电磁仿真软件的EM工作室对某飞行器的等比例模型进行了雷击附着点的仿真研究,并详细讨论了放电间隙尺寸、雷击方位等相关参数的选择对飞行器闪电分区的影响,通过数值仿真的结果完成了对飞行器的闪电分区并与SAE-ARP5416标准分区进行对比,证明该方法是可行的,结论对该飞行器的雷电防护设计有重要的参考价值。
Lightning strike directly threatens the flight safety of the aircraft. Based on the in-depth study on the lightning strike characteristics of the lightning electromagnetic pulse (LEMP) and the lightning protection performance of the aircraft, In this paper, an electrostatic field analysis method is used to simulate the lightning attachment point of an aircraft in an isometric model using the CST electromagnetic simulation software EM studio. The selection of relevant parameters such as the size of the discharge gap and the location of lightning strikes is discussed in detail. Based on the results of numerical simulation, the lightning partitioning of the aircraft is completed and compared with the SAE-ARP5416 standard partition, which proves that this method is feasible. The conclusion has important reference value for the lightning protection design of the aircraft.
