Abstract

Even on generic wind tunnel models the surface pressure distribution may show very complex structures, which cannot be detected by means of classical pressure transducers, due to geometrical and structural limitations. Therefore the systematic investigation of pressure distributions for comparison with CFD results on a generic delta wing planform for a range of Mach numbers, angel-of-attack, and yaw angle presented here is achieved by using the lifetime-based pressure-sensitive paint (PSP) technique. The experiments were conducted in the transonic wind tunnel DNW-TWG in Göttingen. Besides static pressure distribution the acquisition of a set of images for averaging allows for RMS-analysis to provide information about unsteady effects. Methods for improving reliability of the PSP lifetime system are presented.
