Abstract : Aerodynamic calibration data were obtained in the test section of the PWT 16-ft Supersonic Tunnel to supplement previous calibration surveys. Recent surveys covered a ten-foot length of test section immediately downstream of the previously surveyed region. These surveys were obtained with an eight-foot traversing rake utilizing pitotwedge, pitot, and cone probes. The data obtained from these surveys included the nozzle pressure recovery and the Mach number and flow misalignment distributions on and east and west of the tunnel centerline. Correlations of average centerline Mach number and pressure recovery with corresponding measurements obtained with a retractable pitot-wedge probe were obtained at nozzle contour numbers from 2.25 to 3.00.
