摘要： A pitch control system for blades on a rotor of an aircraft has a gimballing rotor hub (31) and a plurality of step-over arms (61) connected to the hub and capable of pivoting relative to the hub about a pivot axis. Each of a plurality of pitch links (55) connects one of the step-over arms (61) to a flight control system for pivoting the connected step-over arm (61) about the pivot axis and relative to the hub in response to inputs from the control system. Each of a plurality of step-over links (69) connects one of the step-over arms (61) to one of the blades for rotating the associated blade about the pitch axis in response to pivoting of the associated step-over arm.

摘要： A rotor assembly (11) for a rotary-wing aircraft, the rotor having a central hub assembly with a flexure-type, twist-shank yoke with multiple arms (19), each arm (19) being adapted for a rotor blade to be mounted thereto. The arms (19) provide for pitch changes of blades (15) attached to the yoke through twisting of portions of the arms about a corresponding pitch axis. An inboard pitch bearing (37) associated with each arm (19) is attached to the hub assembly and allows for rotation of the attached blade about the pitch axis, the inboard pitch bearing (37) also allowing for out-of-plane motion of the arm relative to the hub assembly about a flapping axis. An outboard pitch bearing (35) associated with each arm is attached to the associated arm a selected distance from the inboard pitch bearing and allows for rotation of the attached blade about the pitch axis.
