An upstream structure of a parabolic shock wave induced in a hypersonic flow by a steady-state high-intensity heat source is examined. A similarity analysis is used to derive a simple analytic expression that allows one to predict the shock wave upstream stand-off distance. The solution of Navier-Stokes is obtained to provide basis for the validation of the analytic expression; a reasonable agreement is obtained between the analytic and numerical results for a number of power source intensities.
