摘要：

An advanced rotation-balance apparatus has been developed for the Ames 12-ft Pressure Wind Tunnel to study the effects of spin rate, angles of attack and sideslip, and, particularly, Reynolds number on the aerodynamics of fighter and general aviation aircraft in a steady spin. Angles of attack to 100 deg and angles of sideslip to 30 deg are possible with spin rates to 42 rad/s (400 rpm) and Reynolds numbers to 30x 106/m on fighter models with wing spans that are typically 0.7 m. A complete description of the new rotation-balance apparatus, the sting/balance/model assembly, and the operational capabilities is given. © 1979 American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
