The program is intended to provide the technology necessary for the integration of hydraulicmechanical interfaces so that rotary actuators may be utilized for fast response, long endurance applications, such as vehicle flight control surface actuation. This is an exploratory program for the investigation of a unique rotary hydromechanical actuator. Fabrication and life endurance testing of an experimental model actuator designed to meet an assumed set of flight test performance requirements were completed. Author
