Measurement error due to temperature is a serious problem to apply the pressure sensitive paints in aerodynamics. A new pressure sensitive paint (PSP) is developed to solve the problem. The binder of new PSP is a kind of fluoro polymers, in which oxygen is diffused rapidly. The rapid diffusion suppresses the error due to temperature. A series of sample tests shows that the characteristics of this new PSP are better than the conventional PSP, because the new PSP has a high-pressure sensitivity and a lowdependence of temperature. A preliminary wind tunnel testing is performed to visualize the flow fields around a delta wing.
