Abstract

To apply Temperature-Sensitive Paint (TSP) technique to boundary-layer transition detection in a cryogenic wind tunnel, the formulation of Ru (trpy) /GP197 has been optimized. It was found that the luminescence intensity of the paint was maximized at dye concentration of 1.21.4mg/ml. Micro cracks were observed at cryogenic temperature on TSP coating thicker than 6 microns. The rms surface roughness could be reduced to 0.15 microns by lapping process.
