Abstract: A rotor assembly includes a hub assembly and a shaft assembly. The hub assembly includes a hub and a first coupling, and the shaft assembly may be coupled to the hub assembly with a second coupling. The second coupling may be configured to facilitate rotation of the hub relative to a shaft of the shaft assembly. A rotor blade may be coupled to the hub assembly with a third coupling and be configured to rotate with the shaft. The first coupling may be configured to couple the hub to an actuator and transmit movements of the actuator to the hub to facilitate cyclic pitch control of the rotor blade. The rotor shaft may include arms and the hub may include a body coupled to the rotor blade by the third coupling and pairs of extensions that extend from a surface of the body to receive the arms.
