The major hypersonic aerodynamic results obtained experimentally from the 0.010-scale (51-0) 140A/B orbiter vehicle are presented. The test was conducted over an angle-of-attack range from 20 to 35 degrees for nominal Mach numbers of 16 and 20. The Mach 16 data were obtained at Reynolds numbers, based on model length, of nominally 0.54 x 106 and 1.18 x 106. The Mach number 20 data were obtained at nominal Reynolds numbers of 0.08 x 106 and 0.27 x 106. Various elevon deflections and body flap deflections were tested for determination of control effectiveness. The test objectives were: (1) verify December 1973 aerodynamic Design Data Book estimates for Mach number greater than 10; (2) determine configuration forward and aft trim boundaries and control characteristics; (3) determine high Mach number - low Reynolds number effects; (4) determine if positive control surface flow separation is present and magnitude of separation effects.
