| Abstract: |
| Under complex electromagnetic environment, flight equipment is likely to be disturbed by electromagnetic pulses, which causes flight route deviation or crash. In order to increase its immunity to electromagnetic pulses, the effect experiment of electromagnetic pulse on flight control equipment was carried out by UWS-HPM. Using the method of circuit check and analog simulation, the action mechanism of electromagnetic interference was drawn by experimental result. Under common-mode current and difference-mode voltage combined action, the control box deliver distorted control instruction that can make aircraft to crash. Aiming to the interference mechanism, the protection methods of flight control equipment was proposed by software and hardware combination. |
