  • Lightweight low drag rotor pitch beam
    Patent number: 11433996
    Abstract: A pitch beam movable by a pitch change shaft to adjust a pitch of at least one rotor blade of a rotor system via a pitch linkage includes a first surface having a generally planar configuration, a smooth second surface disposed opposite the first surface, and a sidewall extending between the first surface and the second surface. A pitch linkage connection point is disposed at the sidewall to which the pitch linkage is attachable. An interior is defined between the first surface and the second surface and an opening extends through the first and second surface at a rotational axis of the rotor system to which the pitch change shaft is attached. Movement of the pitch change shaft moves the pitch beam and adjusts the pitch of the at least one rotor blade via the pitch linkage attached at the pitch linkage connection point.
