The Pressure-Sensitive Paint (PSP) measurement was applied to low-speed testing at WINTEC / ISTA of JAXA. The accuracy of PSP was evaluated varying flow speed and an attack of angle. Pressure images on a model surface were clearly visualized, indicating that the PSP system was available to low-speed testing.
