Abstract : The spin motor for the Air-Launched Air-Recoverable Rocket (ALARR) vehicle is designed to provide the spin required by the NESCO payload for its operation. A secondary objective is to maintain the vehicle orientation during payload operation above 300,000 feet altitude where aerodynamic forces are negligible. The payload performance is sharply degraded by vehicle orientation errors, which can be caused by thrust differences between the motor nozzles. AFSWC (SWT) tested the spin motor system to determine the spin rate and orientation errors. The spin rate was lower than expected and below the payload requirement. The orientation errors were smaller than the measuring capability of the measuring system used and should not degrade payload performance. (Author)
