  In a recent publication Hornung (2019) showed that the shock wave stand-off
distance and the drag coefficient of a cone in inviscid hypersonic flow of a
perfect gas can be expressed as the product of a function of the inverse
normal-shock density ratio and a function of a cone-angle parameter, thus
reducing the number of independent parameters from three (Mach number, specific
heat ratio and angle) to two. By making a large number of Euler computations,
analytic forms of the functions were obtained. In this article the same
approach is applied to the symmetrical flow over a wedge. It turns out that the
same simplification applies and corresponding analytical forms of the functions
are obtained. The functions of the normal-shock density ratio are compared with
newly determined corresponding functions for flow over a circular cylinder.
