Computer Programs for Prediction of Lightning Induced Voltages in Aircraft Electrical Circuits

Abstract

The report describes a computerized program to define the induced circuit voltage within an aircraft electrical system due to a lightning strike on the aircraft. One routine of the program (DIFFUSION) calculates the effect of magnetic fields caused by current on the aircraft skin. The other routine (APERTURE) calculates the magnetic field that enters the aircraft because of an opening. The induced voltages are then calculated for any given electrical circuit. The program has defined geometrical configurations for a fuselage, rectangular wing, and empennage sections. A subroutine calculates the current distribution on the skin of the section being analyzed. The program input current and output voltage are in the time domain.
