This is a final report defining the results of a design study for a flightworthy low pressure pneumo-mechanical servomechanism for actuation of flight control surfaces. The design concept presented is the unique DYNAVECTOR Actuator, Model PH-370-B1, designed for installation into a F101B test vehicle in parallel with the existing hydraulic rudder control system. The DYNAVECTOR actuator is an integrated motor-epicyclic transmission servomechanism capable of meeting all specified performance requirements when operating on 50 psig compressor bleed air. The analyses conducted during this study have established the characteristics andor requirements of the following Duty cycle and power supply characteristics, Servo system characteristics, Reliability and failure mode characteristics, Bleed air consumption requirements, Qualification test requirements, Assembly and components design requirements. The conclusions of this study confirm the feasibility of a low pressure DYNAVECTOR Rudder Actuator.
