摘要： A ram air turbine has turbine blades connected to rotate a transmission shaft. The transmission shaft is connected to drive a first gear which is engaged to drive a second gear. The second gear is connected to rotate an output shaft extending through a strut away from the transmission shaft. A governor arrangement is configured to change a pitch angle of the blades in response to speed, and includes counterweights acting on a spring in the governor arrangement. The governor spring is positioned on an opposed side of the strut relative to the 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.

摘要： In a method for blade load reduction control of a rotor of a wind turbine, the rotor includes a plurality of blades, and a pitch angle of each blade is controllable by an actuator. The method includes measuring mechanical load parameters on the rotor, providing control for a collective pitch blade setting based on a rotor speed; providing individual pitch control including transforming the mechanical load parameters from a rotational reference frame to a mechanical load on the rotor in a fixed reference frame; determining from the mechanical load two multi-blade pitches; correcting the multi-blade pitches to corrected multi-blade pitches using actuator limitations; inversely transforming the corrected multi-blade pitches to an individual pitch deviation for each blade in the rotational reference frame; adding up for each blade, the individual pitch deviation to the collective pitch to form an individual pitch; and setting each blade to the respective individual pitch.
