Pressure-sensitive paint (PSP) technique has been more and more popularly applied in industrial fields because of its unique advantages such as high cost-efficiency, time-saving preparation, and convenient operation. Investigation on characteristics of PSP formulation plays an essential and primary role in research and industrial application. Impinging jet supplies an effective access to certify and validate the feasibility of PSP recipe on research and industrial purposes as well as its potential application prospective. Pressure measurement, which demonstrated the resolution capability of pressure gradient along the vane surface, has been conducted with high pressure air jet impinging on a single stator vane based on self-established measuring system and in-house paint formulation. The fact that obtained pressure distribution images of jet impinging visually displayed the pressure gradient on vane suction surface indicated the resolution property on pressure change except for distinct inaccuracy resulting from narrower calibration pressure range for broader application regime. A qualitative examination of response time was also conducted by fast CMOS camera, which shows potential capability of fast response to pressure variation.
