공력-구조-RF 스텔스 통합 전산해석 시스템 연구

An integrated multi-disciplinary design system plays a critical role in the preliminary design of an aircraft. In this paper such system is developed for the multi-disciplinary computation and design; aerodynamics, elasticity, and radio frequency stealth. Common data base of geometry and structured grids is generated and used for aerodynamic, structural and electromagnetics analysis. The Navieri-Stokes CFD, FEM, and CEM technique are used for aerodynamic, structural, and RF stealth computations, respectively.
