Abstract
Alson E. Hatheway Inc. in conjunction with the Schaeffer Magnetics Division of Moog Inc. has developed a dual-stage high precision structural actuator for use in precision spacecraft structures. The actuator is designed to operate equally well anywhere in the range from 20 degrees K to 300 degrees K. A test program has just been completed to evalute the performance of the actuator at the limits of the temperature range and this paper describes the test facilities, the test and the results. The actuator demonstrated a full stroke in excess of 10 millimeters and a resolution of 7.2 nanometers. The performance at cryogenic and room temperature appear to be the same.
