스텔스 비행체의 RCS 및 공력 최적 설계

A combined RCS and drag optimization study is conducted for the purpose of developing a stealth wing design. A CEM code based on the Maxwell equations is used for the RCS analysis while a CFD code based on the Euler equations is used for the drag analysis. From results of the optimization study based on a adaptive range genetic algorithm, it is found that RCS and drag are minimized in an airfoil dented near 20 percent of the chord length aft of the leading edge.
