飞翼隐身特性数值模拟

Numerical Simulation of the Flying Wing Stealth

摘要:

为了设计出高隐身飞机,对飞翼进行总体设计。应用 CATIA软件,对飞翼进行概念设计,生成三维数字样机；基于物理光学法和等效电磁流法,应用自编的 RCSAnsys软件对飞翼的三维数字样机进行隐身特性数字模拟,得出飞翼在各频段雷达波条件下 RCS均值。结果表明,飞翼隐身设计,能够得出高隐身飞机,可为飞机总体与隐身 设计提供理论依据与技术支持。

Abstract:

In order to design aircraft with high performance of stealth, the overall design was carried out on the flying wingaircraft. The 3D digital prototype of the flying wing conceptual design was generated by using of CATIA. Based on thephysical optics method and the method of equivalent currents, a program named RCSAnsys was written to analyzes thestealthy characteristics of the flying wing, the average RCS characteristics of the flying aircraft in the condition of differentradar wave spectrum were gotten finally. The results showed that by using the flying wing stealth, the flying wing stealthwith high performance of stealth could be designed out, which could provide the academic gist and technical support forthe aircraft overall configuration and stealth design.
