PRESSURE DISTRIBUTION MEASUREMENTS ON SEVERAL RIGID HYPERFLO MODELS AT MACH 3.0 AND 4.0.

Abstract

The internal and external surface pressures on rigid wind tunnel models of Hyperflo canopies of 5%, 10%, and 15% geometric porosity, with mesh and grid porous areas, were measured, and Schlieren flow photographs were taken. The measurements were conducted in a 12 in. x 12 in. supersonic wind tunnel in free-stream and in the wake of a cone-cylinder forebody at Mach numbers of 3.0 and 4.0 and Reynolds numbers/ft. from 860,000 to 2,990,000.
