Electromagnetic Compatibility Simulation Analysis of Helicopter Engine Irradiated by EMP

Abstract

Abstract Due to the rapid development of battlefield complex electromagnetic environment research in recent years, electromagnetic pulse (EMP) environment has gradually stepped onto the stage of information war. To make low altitude flying electronic equipment engine plays its normal combat performance in the EMP radiation environment and ensure the integrity of electronic equipment, it is urgent to research in this field. In this paper, according to GJB-1389A and other standards, CST simulation software is used for simulation analysis. Through simulation, field strength and cable coupling with the airborne engine of an armed helicopter under EMP irradiation are predicted. The conclusions have a certain guiding significance of the further study of the protection against the complex electromagnetic environment of the engine.
