Indirect Effects Simulation of Lightning on Military Aircraft Based on EMA3D

Lightning indirect effect simulation is of great significance to lightning protection design of military aircraft electrical and electronic equipment. It provides important basis for laying of airborne wire harness, arrangement of airborne equipment and lightning protection.In this paper, the indirect effects of thunder and lightning are simulated by using the Su-27 aircraft as the simulation object.Based on two lightning paths, the forward fuselage, the middle fuselage, the rear fuselage and the wing of the aircraft are simulated and evaluated.
