SOME SOLUTIONS OF KARMANS EQUATION DESCRIBING THE TRANSONIC FLOW PASTA CORNER POINT ON A PROFILE WITH A CURVILINEAR GENERATRIX

Transonic flows in the neighbourhood of a corner point on a profile ar e investigated in a class of self-similar solutions of Karman's equati on. The corner point is formed by the intersection of two smooth curve s, the tangents to which make a convex angle. The generatrix, which li es in the subsonic part of the flow is assumed to be curvilinear and t o vary according to a power law. Values of the self-similarity index a re found for which transonic hows are possible either with a free stre amline or with a rarefaction wave.
