THEORETICAL OPERATING RANGES AND CALIBRATION RESULTS OF THE ARL TWENTY- INCH HYPERSONIC WIND TUNNEL

Abstract

Results of calibration tests conducted in the ARL 20 in. hypersonic wind tunnel are presented. Included are total pressure surveys, total temperature surveys, and blockage tests of various model configurations. All tests were conducted with the nominal Mach 14 throat installed in the tunnel. The total temperature survey was carried out in a direction normal to the flow at a fixed axial station, with the total pressure survey being conducted in the normal direction also, but at various axial locations. The models used in the blockage tests included hemisphere cylinders of various sizes and a 20 degree included-angle cone. The range of flow parameters which may be simulated were computed from the predicted operating limits of the tunnel and are presented in graphical form. These graphs include the range of pressure, temperature, density, and Reynolds number possible in the HTS-14.
