| Research Abstract |
A simultaneous image acquisition method of 2-color pressure-sensitive paint (PSP) was studied for obtaining unsteady field measurement including an unsteady motion of the PSP coated object. This consists of a 2-color PSP composed of the reference and signal luminophores. The reference output from the PSP enables us to obtain the reference image related to the pressure-independent output. This was used to extract the pressure-dependent image from the signal output from the PSP. By acquiring the reference and signal image simultaneously, a global pressure measurement including an unsteady motion can be obtained. A fast-frame rate color camera was used to acquire the two images simultaneously. The two-color PSP provided the reference output around 520 nm, and the signal around 620 nm. These corresponded to the green and red images of the camera. By using a porous supporting matrix of TLC (thin-layer chromatography) plate, the developed PSP could provide a fast response of 80 microsecond characterized by a shock tube. The developed system was applied to a flutter measurement.
