Experimental Measurements in the Wake of 10 Degree Half Angle Blunted and Pointed Cones at Hypersonic Flow Velocities

Abstract

Experimental measurements were performed in the wake of a 10 deg half angle cone at 0 deg to 10 deg angle of attack with respect to the flow, and of a blunted cone of .333, and .666 bluntness ratio at 0 deg angle of attack. A rake of closely spaced (1 in. apart) electrostatic probes was utilized to obtain the relative electron density distribution at several stations behind the base of the cone. These electron densities can, under certain conditions and in most parts of the wake, be interpreted in terms of the neutral density distributions. It is concluded that the hypersonic shock tunnel in conjunction with simple electrostatic probes can, within limits, provide a good qualitative insight into the flow field of complex aerodynamic models.
