飞机雷电初始附着仿真方法研究

摘要

Using the numerical simulation method to judge the lightning initial attachment condition of air -craft,providing the basis to the lighting zoning of the aircraft .Simulate the aircraft′s potential distribution with plate electrode or rod electrode under lightning environment ,according to the value of the potential distribution to judge whether the cutting-edge parts of the aircraft can be lightning′s interpoint or out-point.The electric potential using normalization processing method , providing uniform standard to the lightning initial attachment of the aircraft .%应用数值仿真的方法判断飞机雷电初始附着情况，为飞机的雷电分区提供依据。仿真飞机在平板电极和棒电极模拟的雷电环境下的电势分布，通过飞机表面的电势分布大小判断飞机表面尖端部位是否会成为雷电的入点或出点。通过对电势的归一化处理，为整机的雷电初始附着提供统一基准。
