This paper describes a facility for the acquisition of simultaneous high quality particle image velocimetry (PIV) and unsteady surface pressures with high spatial and temporal resolution. The facility, developed through a long-standing collaboration between the Department of Aerospace Engineering at Glasgow University and the Fluid Loading and Instrumentation Centre at Heriot-Watt University, is currently being used in collaborative projects and has the potential to provide a level of detail previously unattainable for CFD validation. Results from both measurement techniques will be presented to demonstrate the range and potential of the two systems. In addition, the value of combining the two techniques will be demonstrated by results from a blade-vortex interaction experiment in which both methods were applied. Finally, future applications of the combined system will be discussed.
