Research on Simulation Method of Aircraft Lightning Suppressor

Lightning strikes on airplanes are inevitable. Therefore, lightning suppressors will be widely used for lightning protection of aircraft electronic and electrical equipment, ensuring the safety of electronic and electrical equipment. In current engineering practice, most of the research on lightning suppressor is based on testing verification of their protective ability, which has problems such as protection failure, long test cycles, high design costs, and inability to extract key signal features. Therefore, this article conducts research on the simulation method of lightning suppressors to analyze the protective effect of lightning suppressors, simulate and analyze the current and voltage characteristics of lightning suppressors and loads, and calibrate the simulation model parameters through lightning test results.
