摘要
A rotor assembly (701) includes a yoke (705) operably associated with a rotor blade (715). The yoke (705) includes a first device (711) and a second device (713) that attach the rotor blade (715) to the yoke (705). The first device (711) is configured to allow transverse movement of the rotor blade (715) about a chord axis and rotational movement about a pitch-change axis. The second device (713) is configured to allow rotational movement of the rotor blade (715) solely about the pitch-change axis. The method includes rotating rotor assembly (701) about a first plane of rotation, while retaining a relatively stiff out-of-plane rotation and a relatively soft in-plane rotation during flight.
