Kurzfassung
A general overview of Pressure Sensitive Paint measurements carried out in the DLR Institute of Aerodynamics and Flow Technology will be given. Specifically, this talk will concentrate on the successful application of this technique to the measurement of surface pressures on two different Scramjet nozzles in a Mach 7 flow of the Hypersonic Wind Tunnel H2K of the DLR in Cologne. The agreement with results from pressure taps is very good. Physical insights into the flow phenomena could be obtained, and an optimization of the gas injection into the nozzle plenum chamber could be carried out. The influence of surface temperature gradients was assessed, as were error sources discussed. The utilization of PSP on a large, industry-scale wind tunnel was carried out successfully, pointing the way for the longer term aim of applying PSP to flows of much shorter duration, such as in the High Enthalpy Shock Tunnel HEG of the DLR in Göttingen.
