载人飞艇雷电防护设计和适航符合性验证OA

Manned airship will be hit by lightning.In order to avoid lightning flow affect the airship flight safety dam-age,in the manned airship design need to consider building lightning protection channel,and during the develop-ment process,the design is validated for airworthiness compliance.Based on the design and implementation process of the lightning protection requirements,the lightning protection design and airworthiness compliance verification method of AS700 manned airship are studied.Firstly,the lightning circulation channel is constructed according to the structure and materials of the airship,and then the lightning circulation path is analyzed under the ultimate flight attitude of the airship,to ensure that the lightning circulation channel is reasonable and meet the requirements.Fi-nally,the key equipment/components are selected to carry out the lightning airworthiness compliance verification test.The results show that the lightning protection design of AS700 manned airship meets the airworthiness require-ments and has obtained the TC certificate.
