This paper presents an application of temperature sensitive paint (TSP) technique to measure full-field surface heat transfer rates in short-duration wind tunnel. Tests were performed on blunt-nose cone model (nose radius 10 mm, cone half-angle 10/spl deg/) in shock wind tunnel UT-1 (TsAGI) operated on Ludwig scheme at Mach number M=6 with flow duration 40 msec. Reynolds numbers calculated by nose radius were ranged between 60000 and 210000. Two type of TSP were used: monochromatic and two-color. Two-color paint contains additional temperature insensitive dye to compensate excitation light intensity variation. Experimental results have shown good repeatability but heat flux on the model nose was lower than CFD prediction and thermocouple measurement.
