Abstract : A wind tunnel test program on the 7-caliber Army-Navy Spinner Rocket has been completed in the NOL 40 X 40 cm Aeroballistics Tunnel No. 1. Magnus force and moment measurements have been mad at Mach numbers of 0.291, 0.600, 0.810, 0.914, 1.57, 1.77, 1.90, 2.21 and 2.46 and at angles of attack up to 20 degrees. The Magnus measurement problem for the wind tunnel is examined, and a discussion of the instrumentation used to overcome this problem is presented. The results of the test program are presented in coefficient form and a comparison with the results from the Aberdeen Ballistics Ranges is presented. It is shown that there is agreement between the Naval Ordnance Laboratory wind tunnel and the Aberdeen range results at supersonic speeds, and that the Magnus coefficients are non-linear with angle of attack.
