Pressure Sensitive Paint Data on the Transonic Technology Wing Demonstrator (TST) in the AEDC Propulsion Wind Tunnel 16T

Abstract

An improved prototype Pressure Sensitive Paint (PSP) data acquisition and processing system was used to acquire surface pressure data using PSP on the Dornier Alpha Jet with a Transonic Technology (TST) Wing in the AEDC Propulsion Wind Tunnel 16T. A paint formulation developed at the University of Washington was used because of its superior performance characteristics. The process that permits the determination of surface pressure from the paint is described, as well as the image processing that is required. Also, the special illumination and detection components that make up the data acquisition system are presented. Comparisons of conventional pressure measurements and Computational Fluid Dynamics (CFD) results made with the PSP data are presented.
