Research on Lightning Attachment Zone Dividing of Aircraft

Test methods are more employed when researching lightning attachment zone of aircraft, and theoretical methods are not. By researching the mechanism of lightning electrification and development, flying aircraft discharging, initial attachment of lightning leader of some kind of aircraft with the theory of “point effect for supplement, lightning attachment zone of aircraft was further divided theoretically. A 1:3 scale model lightning attachment point test of the aircraft was made by referencing the standard GJB3567 and SAE ARP5416, the correctness and feasibility of this kind of method of lightning attachment zone dividing was proved, which contributes to the research of lightning attachment zone of multiple kinds of conductors including aircraft to a certain extent.
