Cockpit Protection Analysis for Digital Pilot against Soft Kill from High Power Microwave

Abstract:

A body finite difference time domain (FDTD) grid modeling engineering method and a simplified parallel FDTD algorithm are brought forward based on frequency-dependence electromagnetic equation by nonparametric curve fitting. By a shielded construction designed soft kill analysis against high power microwave (HPM) is carried out respectively on 3D simple and digital pilot in fighter model with a scale of 1:1, which is electrically huge and very complex in geometry and electromagnetic characteristics. The simulation tests show that the protective effectiveness to soft kill is good with shielded construction at 0.3-6GHz, HPM protective efficiency evaluation on digital pilot model is more optimistic and complex than that on simple pilot model, and speedup ratio of the presented approach can compare with that of the conventional method.
