Kurzfassung
Studies on the stability of three-dimensional hypersonic boundary layers for 7 and 15 deg. half-angle cones at 0 and 6 deg. angles of attack are reported. Measurements were carried out in the Hypersonic Ludwieg tube Braunschweig at Mach number 6. Surface mounted pressure and heat flux sensors were used to determine the spatial extension, frequency contents, and wave structure of second-mode and cross-flow instabilities. Infrared thermography was used to capture location, direction and growth of stationary cross flow instabilities. The experimental data are analyzed and compared to the results of corresponding stability computations.
