电磁脉冲武器对军机座舱后门耦合效应及软杀伤分析

Research on Back-Door Coupling Effect of Low-Frequency Mononuclear EMP Weapon on Cockpit and Analysis on Soft Kill to Military Aircraft

摘要:

针对飞机电磁脉冲武器软杀伤和座舱耦合效应缺乏定量研究的问题,文章基于时域有限差分方法(FDTD)建立了一套电磁脉冲后门耦合效应建模与软杀伤分析流程,并以某作战飞机为例,开展了低频(0~100 MHz)电磁脉冲武器的座舱耦合效应仿真试验,获取和分析了软杀伤数据,从而提出了一种采用座舱玻璃导电膜的低频电磁脉冲武器软杀伤防护方法。软杀伤分析结果表明,基于功率密度的软杀伤易损性分析具有良好的工程适用性,而且防护方法对低频电磁脉冲武器具有较好的屏蔽效能。

Abstract:

The problem of research on coupling computation of low-frequency mononuclear EMP weapon and soft kill to aircraft was analyzed. Based on FDTD method, a flow chart of modeling and analysis for back-door coupling effect of low-frequency mononuclear EMP weapon and soft kill was constructed. A simulation experiment of low-frequency mononuclear EMP weapon was carried out on a fighter,the soft kill data was acquired and analyzed,and a guard method were proposed. The simulation tests showed the shielding efficiency of electric film to soft damage.
