Abstract
An electromechanical pitch control system for modifying a collective blade pitch of a multi-blade propeller includes a pitch control rod mechanically coupled via a distal end to a plurality of blades of a propeller, a bearing assembly operatively connected to a proximal end of the pitch control rod, and an electric actuator operatively connected to the bearing assembly. The bearing assembly allows the electric actuator to remain stationary while the pitch control rod rotates with the propeller. The electric actuator is configured to translate the pitch control rod in a longitudinal direction for adjusting an incidence angle of the blades.
