Abstract:

The strong similitude of the hypersonic flow of a perfect fluid about blunt bodies is considered. Using a continuous flow wind tunnel, the pressure distribution, shock-wave shape, and shock detachment distances about spheres and cylinders are obtained at Mach numbers from 8 to 15 and at Reynolds numbers from 2,000 to 75,000. With the help of low Mach number data from the open literature, correla tions of the observed quantities are formulated, demonstrating a near Mach number independence of the flow. A correlation of the sphere shock profile by the normal shock density ratio is of special interest. Author
