Abstract

Pressure-Sensitive Paint (PSP) system is a useful measurement tool for acquiring overall pressure images on an aerodynamic model. However, the luminescent intensity of PSP depends on both pressure and temperature. Thereby, Bi-luminophore PSP (bi-PSP) has been developed in order to correct the error due to temperature dependence of the PSP. The bi-PSP contained pressure- and temperature-sensitive dye. Tetranuclear europium (III) complexes and PdTFPP were used as temperature- and pressure-sensitive dye, respectively. The Eu complex was developed as a temperature sensor of the bi-PSP in cooperation with Osaka University. The luminescence intensity of the Eu complex was highly sensitive to temperature and insensitive to pressure.

The bi-PSP was examined using a painted coupon and its characteristics were clarified. As a verification test, pressure distributions on a supersonic transport (SST) model at low-speed flow were acquired by the bi-PSP measurement system. The root-mean-square difference of CP between PSP and tap data at 50m/s was approximately 0.1 (150 Pa) at flow speed of 50m/s, indicating that this bi-PSP system can accurately measure pressure as an IR camera combined PSP system. Furthermore, this bi-PSP system was more convenient rather than an IR combined PSP system for practical use.

Keywords: Pressure-Sensitive Paint, Bi-Luminophore Paint, Low-Speed Flow
