Static longitudinal and lateral-directional aerodynamic characteristics of a candidate lifting entry research vehicle were measured at Mach numbers of 6 and 10 in air and at Mach 20 in helium. The effects of nose bluntness, body flap deflection, and elevon deflection were examined over a range of angle of attack. The vehicle demonstrated static longitudinal and lateral-directional stability at angles of attack from the maximum lift-to-drag ratio (L/D)max to high angles of attack. Sufficient control effectiveness existed to provide longitudinal trim from (L/D)max to high angles of attack. Aerodynamic coefficients predicted using the Hypersonic Arbitrary Body Program were compared to measurement. Good agreement was obtained for lift-to-drag values.
