Pressure-Sensitive Paint Measurements in High-Speed Wind Tunnels

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.　
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.　
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.
