Experiment and Simulation Research of Lightning Injection Test for Airborne Antenna

Lightning poses a serious threat to the flight safety of aircraft. Airborne antenna, as an external structure of aircraft, is probably to become a lightning attachment point. When the antenna is struck by lightning, the end of the cable connected to the antenna may produce a short time voltage transient, and cause component failure or equipment malfunction and damage. Based on the method of combining electromagnetic simulation and experiment, the aircraft lightning indirect test of ´╝éinduced transients in external mounted hardware´╝é is studied in this paper. The induced voltage and current in the cable which is connected with the airplane components are analyzed. The work provides a basis for further research on lightning effect of aircraft external structure and lightning protection of airborne equipment.
