Research on HIRF Protection in Semi-Open Area Of the Aircraft

Abstract

With the use of fly-by-wire flight control systems, and the replacement of key equipment in the semi-open area of the aircraft with sensitive electronic equipment, the design of electromagnetic protection in this area is particularly important. Regular long slit designs should be avoided in semi-open areas, thus creating some very strong resonance points in the area and exciting a harsh electromagnetic environment. A good structural design can effectively mitigate the enhanced effect of HIRF field strength in the semi-open area. This paper presents a simulation analysis for a typical Semi-Open structure and gives an optimization solution which has a good technical effect.
