Abstract:

The spin motor system for the ALARR Air-Launched Air-Recoverable Rocket 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 where aerodynamic forces are negligible. However, thrust mismatch between the two nozzles of the spin system can cause coning and introduce undesirable orientation errors. Using a pendulum as a measuring device, Air Force Special Weapons Center SWT tested the spin motor system to determine this mismatch. The mismatch was found to be less than 1 percent, a value acceptable for the NESCO payload. Author
