Abstract
An electromechanical boost actuator for aircraft flight control is attached to a mechanical input by a mechanical linkage. The mechanical linkage is also attached to the output shaft of the electromechanical boost actuator. When a pilot or control system manually moves the mechanical input, a position sensor attached to the linkage activates electric motor(s), extending or retracting the output shaft in the direction commanded by the pilot or control system. The motion of the output shaft, acting through the linkage, moves the position sensor to a neutral position, stopping the electric motor(s) and the output shaft when the output shaft reaches the commanded position. Additional linear actuators may inject another control signal in conjunction with the mechanical input.
