摘要
文章研究了飞机雷达罩雷电防护设计参量变化对雷达罩内、外感应电场强度的影响规律,利用EMA3D静电场仿真方法,探究了飞机雷达罩的相对介电常数、分流条长度和数量对罩体感应电场强度的影响趋势。研究结果表明,雷达罩相对介电常数小于10时对其内、外感应电场强度影响较为明显。对某典型雷达罩进一步开展了雷电防护设计研究,获得了不同分流条长度和数量对感应电场强度的影响规律。
In this paper,the influence of the change of the lightning protection design parameters of aircraft radome on the internal and external induced electric field strength of the radome is researched.The effects of the relative dielectric constant and the length and number of lightning diverter strips on the induced electric field strength of the radome are studied by electrostatic field simulation method with EMA3D.The results show that the internal and external induced electric field strength of the radome is affected greatly when the relative dielectric constant of the radome is less than 10.The lightning protection design of a typical radome is carried out,and the influence law of different length and number of lightning diverter strips on the induced electric field strength is obtained.
