摘　　要：雷电作为一种自然放电现象,对飞行安全构成严重威胁.为了进一步提高直升机对雷电的防护能力,根据标准SAE-ARP5416A规定的试验方法,在CST EM Studio中对某型直升机的等比例模型进行仿真计算,对其初始雷击附着区域的划分开展研究.提出了一种基于静电感应理论的直升机初始雷击附着区域划分的仿真计算方法,讨论了该型直升机仿真模型参数设置、具体划分方式等相关内容.通过本文方法仿真计算得到某型直升机初始雷击附着区域,并与标准SAE-ARP5414A的分区结果进行对比分析,验证了该方法的可行性.提出的方法对于今后直升机防雷设计和相关研究工作的开展具有重要参考意义.As natural discharge phenomenon,lightning is a serious threat to flight safety.In order to improve the protection performance of the helicopter against lightning,this paper simulates the full-scale model of a certain type of helicopter and studies its lightning initial attachment zones according to the SAE-ARP5416 Astandard.Putting forward simulation calculation methods based on the theory of electrostatic induction to zone the lightning initial attachment zones of the helicopter.Relevant content about parameters of modeling this certain type of the helicopter and detail zoning methods are discussed.The lightning initial attachment zones are calculated by the methods given in this paper and zoning results are compared with the SAE-ARP5414 Astandard verifying the feasibility of the methods.The proposed methods are of important reference significance for future study of the protection performance of the helicopter against lightning.
