【Abstract】 The pressure-sensitive-paint (PSP) technique is new kinds of dynamic-measurement technique with the characteristic of non-intrusion and the continuous pressure measure on whole model surface. It is now commonly used in stationary wind-tunnel tests in abroad. In this paper,presents the basic principles,the main components of the PSP measurement systems,paint calibration,how to use this technique to measure pressure,were introduced,and the developing of PSP technique was described.更多还原
