Abstract : An investigation was conducted to verify the performance of the new 1,500-lb (normal force) pitch/yaw and roll force oscillation balance systems. These systems are capable of measuring direct, cross, and cross-coupling derivatives. Symmetrical and asymmetrical configurations of the Standard Dynamics Model were tested. Data were obtained at Mach Numbers 0.3 to 1.3 and at angles of attack ranging from -4 to 24 deg. In general, static and direct dynamic coefficients agreed closely with previous data. Cross and cross-coupling coefficients were measured for both configurations. (Author)
