Abstract
Fast response Pressure-Sensitive Paint (iPSP) developed at the German Aerospace Center (DLR) in Göttingen is used for measurements of acoustic and aeroacoustic pressure distributions in a rectangular cavity at transonic (M = 0.9) and supersonic (M = 1.1) Mach numbers. The iPSP was applied to the ceiling of the cavity as well as to one of the doors. Different data analysis methods are applied to the results to increase the signal-to-noise ratio (SNR). Simultaneous measurements with conventional measurement technique using high speed pressure transducers (Kulites) are performed and used to reference the iPSP results. Both measurements are compared showing a good agreement.
