Abstract:

A prototype mechanical servo-actuator was tested under simulated loads to determine its suitability for use in powering flight control systems for helicopters. Tests included frequency response, step response, threshold, hysteresis, endurance, and emergency operation, and were compared with similar tests of a typical hydraulic servo. Recommendations are made regarding design changes for further investigation.
