Lightning Ignition Source Control Technology for Aircraft Fuel Tank Structure

This paper mainly studies the match between the design features of typical wing parts and the lightning current environment by comparing and analyzing the parameters (1): lightning spark threshold of sample pieces designed according to the structural characteristics of aircraft and the parameters (2): lightning simulation current of certain structures of aircraft. A useful method is summarized through the process of comparison, with which the ignition source of the aircraft fuel tank can be effectively controlled combined with the known aircraft lightning environment simulation model.
