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
