Although the lifetime-based PSP measurement has several advantages compared to the intensity-based method, it is still not a commonly-used PSP technique in wind tunnel testing. One problem is a non-uniform distribution of the measured lifetime over the coated surface. Theoretically PSP lifetime should be independent of the excitation light distribution, dye concentration and paint thickness; however, the measured lifetimes over the coated PSP surface are sometimes not uniform. In this work, as a first step, PtTFPP-based PSP for the lifetime-based method has been developed to improve this lifetime uniformity. Special attention was here paid to the effect of basecoat material and polymer. In the second part, the lifetime-based PSP method is applied to a transonic wind tunnel test. As a result, quantitative pressure distributions can be obtained by the lifetime-based method at M = 0.5 and 0.3. The PSP results show characteristic pressure distributions on a delta wing model.
