A motion-capturing pressure sensitive paint (PSP) system is used to collect transient surface pressure data on a 30mm diameter sphere model in free flight at Mach 1.5. The motion-capturing PSP is able to remove effects due to variations in illumination during free flight, drastically reducing error in free-flight pressure measurements. Luminescent images of the model are collected at 100kHz with an exposure time of 3.75μs using a high-speed camera. The sphere is fully in view for 7 frames, or 70μs. Transient data from each frame is collected to produce a free flight pressure map on the surface. Validation of the measurement is performed using a time-averaged transient computational fluid dynamics (CFD) simulation in Ansys Fluent. The mesh consisted of 6.96 million cells and far field pressure boundary conditions are used. The PSP measurement agrees with the CFD simulation both qualitatively and through a trace across the equator of the sphere.
