Abstract
An electromechanical blade pitch control system includes a propeller hub, a blade having an adjustable pitch angle, and a blade bearing hub operably coupled to the blade. The system includes a linear actuator operably coupled to the blade bearing hub and a rotary actuator operably coupled to the linear actuator via a planetary gear system. The system is configured such that the blade bearing hub, linear actuator, and rotary actuator are housed within the propeller hub, and further configured such that actuation of the linear actuator results in a change in a pitch angle of the blade.
