Research on Lightning Attachment Points Simulation for Aircraft

The lightning is threatening to the safety of flying aircrafts.Based on the purpose of doing research on LEMP characteristic for aircrafts deeply,improving the capability of aircraft LEMP protection.This paper apply a method of electrostatic analysis,doing simulation research on lightning attachment point for a isometrical model of aircraft by the EM studio of CST electromagnetism simulation software.The factors that influence lightning subarea results such as the gap spacing,discharging polar have been discussed detail,and accomplish lightning subarea through the numerical simulation result and make comparison to the SAE-ARP5416 standard of lightning subarea,proving this method is viable,so the result have a important reference value for this aircraft lightning protection design.
