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 numbersft. from 860,000 to 2,990,000.
