CONSTRUCTING OF SHOCK POLAR FOR THE CONCAVE CURVED SHOCK

P.I. Ivanov

The problem is related to the development of the methods of the figuring of aerodynamic characteristics of concaved bodies “parachute” type, streamlined by supersonic gas stream. In the present work based on the results for convex curved shock, achieved in due time by A. Busemann, the shock polar equation for concave shock has been made up. When developing the equation of shock polar, the same algorithm that was applied by A. Busemann, was used, with the difference only in connection record for peripheral component of air flow rate up to compressive wave. The examples of shock polar behavior for concave curved shock at different rates of quoted upstream velocity have been provided.

Key words: parachute, supersonic gas stream, curved shock, shock polar.
