The paper describes a computational method of aerodynamic shape design which is one of major applications of high performance computing. The design starts from a base line shape and makes geometrical correction iteratively till the corrected shape realizes a prescribed pressure distribution. The correction value is obtained by simulating a flow and solving an inverse problem. In this research an inverse problem solver has been newly developed for the aerodynamic shape design of multiple wing systems. The solver takes the mutual effect among wings into consideration and provides each section shape of plural wings simultaneously. For flow simulation, Navier-Stokes equations are solved on a vector-parallel machine. Design results show the method using the inverse problem solver and the high performance simulation, is promising to perform complicated aircraft design within a realistic period.
