Kurzfassung
Transition from laminar to turbulent hypersonic boundary layers is the topic of several research Projects world-wide. Most experimental work is done in conventional wind tunnels, although their free stream turbulence does not match free flight conditions and has a significant influence onto the transition process. Experiments performed with the same 3° half angle cone in a conventional and a quiet wind tunnel at Mach 6 justify this approach. The formation, amplification and destruction of second (Mack) modes is compared based on high-speed pressure measurements. In addition damping these modes with ultrasonically absorptive surfaces was tested.
