Electromechanical actuator driven governor for a ram air turbine

摘要

A ram air turbine governor includes a hub carrying multiple turbine blades. A sensor is configured to detect a parameter. A counterweight is coupled to at least one turbine blade and is configured to provide an input to the turbine blade in response to a centrifugal force to move the turbine blade from a first pitch position to a second pitch position. An electromechanical actuator is operatively coupled to the counterweight. A controller is in communication with the mechanical actuator and the sensor. The controller is configured to command the electromechanical actuator and move the turbine blade from the second pitch position to a third pitch position in response to the detected parameter.
