Abstract
Pressure-Sensitive Paint (PSP) is a technique for measuring pressure distributions. This technique is especially important in the aerospace industry for testing pressure distributions on wings or turbine blades. The curvature of an airfoil creates a pressure gradient measured by PSP. Displacement of oxygen also affects PSP, such as film-cooled turbine blades. The normal test set-up includes a blue light, camera, and object with PSP applied. Under the blue light, the PSP will luminesce and the intensity of the luminescence depends on the pressure of the oxygen. The camera will capture images of the luminescence and import data to a program that can convert each pixel to a pressure reading. This research project will test PSP on a film-cooled airfoil in a wind tunnel. The end goal of the project is to differentiate the effects of film cooling and pressure gradients on PSP.
