Abstract : A theoretical analysis of the similarity of hypersonic flows past slender, blunt-nosed bodies is extended to obtain generalized similarity laws for real gas flows with no flow separation past bodies with surface discontinuities. Similarity conditions are established for bodies of various shapes (double cones and cones with spherical bluntness and sharp concave corners). Shapes of shock waves and pressure and enthalpy distributions for various relative body thicknesses are presented in graphs, in the cases of perfect and real gas flows. Observations regarding similitude criteria for a perfect gas flow are also included.
