Abstract
Motion-capturing pressure-sensitive paint (PSP) method is a PSP measurement method that can be applied to capture the surface pressure information on a moving object. It uses two-luminescent outputs from a two-color PSP. One output is independent of the pressure and the other is dependent on the pressure. These provide separate luminescent peaks, which are simultaneously captured by a high-speed color camera. Further description of this method is included in this paper. Some of the unsteady fluid-dynamic measurements by using this method are included in this paper. These include the applications in airfoil flutter and a ballistic range.
