This chapter discusses the inverse design method that is applied to geometry estimation of wind tunnel models. With the pressure distribution obtained from the wind tunnel test as the target of the inverse method, the approximate geometry estimation is carried out. The inverse method used in this chapter is based on the Takanashi's concept that utilizes integral equations and "residual-correction" technique. In this investigation, geometries of two wind tunnel models of National Experiment Supersonic Transport are estimated. One is 23.5% scaled model and the other is 8.5%. The deviation of the inverse estimation from the original CATIA geometry is within a reasonable order, if the manufacturing limitation is considered. The geometry of the 8.5% scaled model is measured for validation by using a 3D non-contact measuring device employing a laser beam and auto-focus system.
