In order to improve the protection performance of the helicopter against lightning, this paper simulates the full-scale model of the UH-60 helicopter and studies its lightning initial attachment zones according to the SAE-ARP5416A standard. 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 modelling 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-ARP5414A standard 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.","PeriodicalId":52557,"journal":{"name":"电波科学学报","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88124553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
