High-Speed Photoinstrumentation for a Hypersonic Wind Tunnel

Robert L. Leighton

Abstract

The application of high-speed cameras and short-duration light sources to measure pressures, forces and flow patterns in a high-velocity (up to Mach 25) short-duration (less than 15 msec) wind tunnel are described. Details of the measuring techniques are given, including the optical systems, lighting, data reduction procedures, measurement accuracies and synchronization methods.
