Investigation and application of two-component pressure sensitive paint technique

The Pressure Sensitive Paint (PSP) technique is one of the important pressure measurement techniques on model surface in wind tunnel test. With the help of PSP technique it is possible to measure pressure of the complex or special model surface that is very difficult in virtue of pressure taps measurements. This report presents the application method of PSP technique, the comparison test results between PSP technique using two-component PSP made in China and classic tap measurement technique on the wing surface of airplane model, showed that the performance of two-component pressure sensitive paint made in china is better than the imported ones and can be substituted for them. The PSP technique used two-component pressure sensitive paint made in china can be used to model pressure testing.
