THE VON KARMAN GAS DYNAMICS FACILITY 1000-FT HYPERVELOCITY RANGE. DESCRIPTION, CAPABILITIES, AND EARLY TEST RESULTS
Abstract
A brief sampling of test results obtained during early operation of the range is presented. Among these are: (1) results of sphere drag measurements over the Reynolds number range 3 Re sub 2 10 to the 6th power; (2) results of the measurements of flow transition locations and wake velocities behind spheres, as obtained through the use of a 35-GHz Doppler radar system; (3) results of measurements of electron densities in the wakes of spheres, as obtained using r-f cavity and microwave techniques; (4) results of the measurement of radiation from the shock caps of spheres; and (5) results of the effect of unit Reynolds number on the location of flow transition in the wakes of cones, as measured using a high sensitivity schlieren system. In each case, the data results presented are correlated with measurements made at other establishments or with data based on available theory. The correlations are shown to be generally reasonable. An appendix describes the VKF 100-ft Hypervelocity Range K, which served as a pilot facility during the development of the 100-ft range and which continues in service.
