As a new optical pressure sensor technique, Pressure Sensitive Paint (PSP) is one of the important techn iques for model surface p ressure m easurement in wind tunnel test s . With the help of PSP , it is possible to do p ressure m easurement on compl icated or special model surface , which is usually difficult to be measured by pressure tap s . Since PSP technique being introduced into China from TsAGI (Russia) , AVIC ARI has investigated two-component PSP technique in high-speed wind tunnel in cooperati on with ICCAS China . T his report present s the principle of PSP technique, test control system development and the test result comparison s between PSP technique with two-component pressure sensitive paint FOP-2 and classic tap measurement on wing surface of an airplane model . T he results showed that the two-component pressure sensitive paint has better performance and can be used for model pressure measurement.

An innovative pressure-measurement technique that employs the tools of molecular spectroscopy has been widely investigated by the aerospace community. Measurements are made via oxygen-sensitive molecules attached to the surface of interest as a coating, or paint. The pressure-sensitive-paint (PSP) technique is now commonly used in stationary wind-tunnel tests; this paper presents the use of this technique in advanced turbomachinery applications. New pressure- and temperature-sensitive paints (P/TSPs) have been developed for application to a state-of-the-art transonic compressor where pressures up to 1.4 atm and surface temperatures to 90°C are expected for the suction surface of the first-stage rotor. PSP and TSP data images have been acquired from the suction surface of the first-stage rotor at 85 percent of the corrected design speed for the compressor near-stall condition. A comparison of experimental results with CFD calculations is discussed.
