Modeling and Simulation of Helicopter Cabin Electromagnetic Environment

Article Preview

Abstract:

Electromagnetic environment (EME) in helicopter cabin is one of the most important indexes for electromagnetic compatibility (EMC) on airborne platform. The simulation results were not accurate enough because of the difficulties in accurately modeling and the large computation. Due to the inaccuracy of the former modeling method which used the typical geometric, the professional software ICEMCFD/AI*Environment (AIE) was employed to restore the helicopter’s original model, based on the obtain of the accurate helicopter model, the Multi-layer Fast Multipole Method (MLFMM) and Combined Field Integral Equation (CFIE) were employed to analyze the variation of the electric field in the helicopter cabin versus the frequency and other factors with a VHF antenna mounted on the helicopter. Both accuracy and computing speed were concerned, the results have some guidance significance to the EMC preliminary design on airborne platform.
