Abstract: We developed a dual-luminophor pressure/temperature sensitive paint (DPTSP) to correct the temperature dependence of pressure-sensitive paint. The DPTSP is composed of two sensor molecules, PtTFPP and Rhodamine B (RhB), and Poly-IBM-co-TFEM as a binder. Temperature was determined from the image of RhB, and the temperature dependence of PtTFPP was corrected using the calculated temperature. To validate the capability of DPTSP for temperature correction, the pressure field on a delta wing model was measured by the DPTSP measurement system. The pressure values obtained with DPTSP were in good quantitative agreement with pressure tap data. It has been validated that DPTSP is effective in correcting the temperature dependence of PSP.
