<p>Flexible beam rotor assembly including a rotatable spindle (3) having a teerering connection to a rotor spar (1) at the axis of rotation, and a nonrotatably mounted spindle housing (6). The spindle housing (6) and spindle (3) protrude through a hole (1a) in the rotor spar (1) and are tiltable. Two spindle pivot axes (C and D) are located below the teetering axis (A) and above the rotor (1') at the rotor axis of rotation. The spindle axis (6) is attached to a pylon (11) by a universal joint (7). Arms (24) are connected to the pylon (11). Pushrods (15) are connected between the arms (24) and spindle housing (6). The pylon (11), spindle housing (6), arms (24), and pushrods (15) form a parallelogram which allows the spindle (3) to move to absorb vibration without changing spindle tilt.</p> |
