A method for calculating inviscid, supercritical flowfields about axisymmetric inlet cowls with center bodies is presented. A finite-difference approximation to the full potential equation is solved under a general coordinate transformation, using a numerical evaluation of the transformation matrix at each mesh point. For the present problem, a boundary-conforming coordinate system was generated by a sequence of conformal and shearing transformations, but this transformation is not essential to the method. Both the quasi-conservative and nonconservative forms of Jameson's rotated differencing scheme are used, and the difference equations are solved by relaxation. Numerical results for pressure distributions generally agree well with experiment. (Kursetz)
