    摘要： A rotor hub assembly is provided including an open rotor hub having a base plate and a plurality of rotor members mounted about a circumference of the base plate. The rotor members are configured to form a plurality of rotor blade openings between adjacent rotor members, and a central opening between all of the rotor members. A plate includes a central body portion and a plurality of arms. Each of the plurality of arms is configured to mount to one of the plurality of rotor members such that the central body portion is generally positioned within the central opening of the open rotor hub.

    摘要： A rotor blade assembly includes one or more flex-beam members and a torque tube surrounding the one or more flex-beam members and extending at least partially along a rotor blade assembly length. A pitch bearing assembly is supportive of the torque tube relative to the one or more flex-beam members and includes at least two outer bearing members secured to the torque tube and an inner bearing member positioned at least partially within the at least two inner bearing members and secured to the one or more flex beam members. A change in a stiffness of the inner bearing member changes one or more dynamic characteristics of the rotor blade assembly.
