摘要: 采用矢通量分裂方法计算了绕翼型的时域电磁散射场特性及雷达散射截面积(RCS)。采用VanLeer矢通量分裂格式求解Euler方程方法计算了绕翼型的气动特性。并用一种简单而有效的数值优化方法对流场解和电磁场解进行了综合优化计算

关键词: 数值优化, Euler方程, Maxwell方程, 多学科综合设计

Abstract: The vector flux splitting scheme is used to calculate the time domain electromagnetic scattered characteristics.Radar cross section(RCS) is then evaluated with equivalence principle and Fast Fourier Transformation.Van Leer's splitting scheme serves to solve the Euler equations to obtain the aerodynamic characteristics.Two obtained solutions are coupled with a simple effective numerical optimization algorithm.

Key words: numerical optimization, Euler equation, Maxwell equation, multi disciplinary integral design
