Indirect effects simulation of lightning on civil aircraft based on EMA3D

Abstract

Abstract: TakingA320 as research object, double exponential function is used to establish the simulation model. By analyzing the distribution of surface current density and electromagnetic field, the electric field attenuation of a certain part of fuselage and the electric field transfer function in different lightning paths are studied. Simulation results show that the surface current density distribution is related to the lightning paths; the electric field distribution is related to the lightning paths and is mainly distributed around smaller curvature radius; the magnetic field distribution is basically consistent with the surface current density distribution; the electric field response bacomes greatest near 1.8 MHz.

Key words: civil aircraft, lightning indirect effects, surface current density, EMA3D
