Abstract:

Measurements of mean-flow and fluctuating-flow parameters were made in the boundary layer of a spherically blunted 0.7-in. radius, 7-deg half- angle cone in an investigation of the stability of laminar boundary layers. The flow-fluctuation measurements were made using hot-wire anemometry techniques. Flow-field profiles and model surface pressures were also measured. The testing was performed at free-stream Mach number 8 with a free-stream unit Reynolds number of 1.6-million per foot. The test equipment and techniques, and the data acquisition and reduction procedures are described. Analysis of the hot-wire anemometer data is beyond the scope of this report.
