Abstract

Two types of the pressure-sensitive paint measurement techniques for high-speed wind tunnels, which include transonic and supersonic ones, were introduced. They were the practical PSP measurement, whose targets were development tests of aerospace vehicles, and the unsteady PSP measurement.　<br>For the practical PSP measurement, PSP/TSP paints, measurement systems, and data reduction methods were described. Then, the global PSP measurement results of the DLR-F6 model were discussed about pressure distribution and variation between those of two AoA cases.　<br>For the unsteady PSP measurement, PSP paint/coating of anodized-aluminum PSP and silica nanoparticle PSP and measurement system were described, then, the unsteady PSP measurement results of the rocket faring model using AA-PSP and those of the delta wing model using silica nanoparticle PSP, whose targets were transonic buffet phenomena, were introduced.
