Institution National Aerospace Laboratory NLR Date 1968-12-31 Abstract An accurate inverse method for the numerical calculation of the supersonic flow around an axisymmetric blunt body is presented. By a suitable transformation the field under connideration is mapped on a rectangular strip. Integration of the equations of motion in the transformed domain is performed by simultaneous application of a third order predictor-corrector process in the subsonic part, and the method of charactaristics in the supersonic part of the field. An iterative technique, based on the minimization of a certain function along the body contour, is used in order to obtain the correct shock wave shape and flow field belonging to a given body contour at a given Kach number. Computational results for spherical bodies, prepared-with the assumption of ideal gas properties, have been obtained, but the method is not restricted to spherical shaped bodies nor to the assumption of ideal gas properties.
