The Arnold Engineering Development Center is one of the leading aerospace test centers to use pressure-sensitive paint PSP technology to measure full-field pressure distributions on the surfaces of test articles in a wind tunnel. This report addresses one of the principal challenges identified prior to the start of this reporting period automated, on-line processing of the large amounts of image data that are acquired during a typical PSP test. This report shows that this image-processing challenge has been met successfully through innovations with regard to automatic image registration and parallel processing. This report also describes additional studies performed to guide the continued development of improved paints and data acquisition strategies for the application of lifetime-based PSP techniques.
