A transonic experiment at hypersonic speed

AIAA Journal, 1964
Cylindrically blunted wedges were tested in a hotshot tunnel at various angles of attack at a Maeh number of about twenty. The geometry was so arranged that the sonic point occurred either on the nose or much further downstream on the corner terminating the body, depending on angle of attack.

Drag reduction on a spiked body at hypersonic speed

The Aeronautical Journal, 2010
AbstractFitting a spike on a blunt body provides a drag reduction at supersonic and hypersonic speeds. In this study, the laminar flow over a spiked, conical body terminated by a spherical cap, inspired by the Apollo re-entry capsule design, was investigated using a hypersonic wind tunnel.
