Research on RCS of Wing Leading Edge Stealth Functional Components Based on FEKO
The design of absorbing structures has become an important development direction for aircraft stealth design.The paper has verified the feasibility and accuracy of the electromagnetic simulation analysis process and method by comparing it with the theo-retical solution of its radar scattering cross-section using standard flat pieces.The influence of electromagnetic parameters on flat plate RCS(Radar Cross section)was obtained through variable parameter analysis of the electromagnetic parameters of the flat plate struc-ture.Combining with the engineering practice,the RCS values of the all-metal wing leading edge structure and the wing stealth lead-ing edge of the combination of wave-transmitting skin and wave-absorbing foam are compared.The results show that the leading edge stealth functional part of the wing surface composed of wave-transmitting skin,wave-absorbing foam,and reflective layer can greatly improve the stealth capability of the structure.
