1. An electromechanical blade pitch control system for modifying a collective blade pitch of a multi-blade propeller, comprising:
a pitch control rod having a proximal end opposite a distal end;
a beta control rod disposed around a narrow portion of the pitch control rod, wherein the distal end of the pitch control rod is threaded and extends outwards from the beta control rod such that a threaded nut is configured to secure the beta control rod about the pitch control rod;
a collar rigidly coupled to the beta control rod, wherein the collar is configured to operatively couple the beta control rod with a plurality of blade-angle control links for a adjusting a pitch of a respective plurality of blades of the multi-blade propeller;
a bearing assembly operatively connected to the proximal end of the pitch control rod; and
an electric actuator operatively connected to the bearing assembly,
wherein the bearing assembly allows the electric actuator to remain stationary while the pitch control rod rotates with the propeller, and
wherein the electric actuator is configured to translate the pitch control rod in a longitudinal direction for adjusting an incidence angle of the blades.
