Recently, pressure sensitive paint (PSP) and temperature sensitive paint (TSP) test of drag reduction and shock control for future large transport aircraft was successfully conducted in HSAI 0.6m×0.6m Semi-Circuit Transonic & Supersonic Wind Tunnel. The purpose of the PSP/TSP test was to obtain airfoil aerodynamic characteristics before and after optimization by measuring the pressure and temperature distribution of the airfoil surface, and to provide data to support the numerical optimization process. The test results indicated that the transition position detected by TSP agreed well with CFD result. The test stood as concrete proof to the possession of TSP test capability of the wind tunnel.
