Pitch-, Yaw-,and Roll-Damping Characteristics of a Shuttle Orbiter at M = 8.

摘要

Wind tunnel tests were conducted for NASA-Langley at M = 8 to determine the pitch-, yaw-, and roll-damping characteristics of a modified 089B shuttle orbiter configuration. Data were obtained utilizing the small-amplitude forced-oscillation technique at angles of attack of -4.9 to 26.5 deg at Reynolds numbers, based on model length, of 1,180,000 to 4,820,000. The orbiter was dynamically stable in pitch, yaw, roll, and statically unstable in yaw for the moment reference of the test configurations. The pitch derivatives were dependent on Reynolds number while the roll derivatives were independent of Reynolds number.
