HIRF interference research and protection of aircraft engine electronic controller
To solve the problem that the aviation Engine Electronic Controller (EEC) is easily disturbed by high-intensity radiation field (HIRF) interference, the plane wave irradiation simulation is performed to simulate the interference effect of HIRF on the EEC through the software CST for the modeling of the EEC. The simulation results show that HIRF can be coupled into the EEC and the electric field strength increases significantly at the resonance frequency. Conducting EEC radiated susceptibility tests at 400 MHz-4 GHz, the test results show that the EEC failure frequency points are 2.40 GHz and 3.84 GHz, the susceptive module is the analog input and output module, The EEC failure frequency is close to the resonance frequency, and the EEC failure is related to the cavity resonance. The wave-absorbing material is mounted inside the EEC and simulation is carried out, and the simulation results show that the wave-absorbing material can effectively suppress the resonance electromagnetic interference, and the results of the study can provide a theoretical basis and reference for the HIRF protection of the EEC.
