  • Device for controlling the pitch of the blades of a convertible aircraft rotor
    Patent number: 6824096
    Abstract: A pitch control device for a blade of a tilting rotor of a convertible aircraft. The pitch control device is external to a rotor hub which is driven in rotation by a mast and connected to the latter by a mechanism for tilting the hub as a whole, each blade is connected to the hub by a coupling for retaining and hingeing the blade in pitch about its pitch change axis. The device includes a pitch change lever, integral in rotation with its blade root about its axis, a pitch control rod, a bellcrank pivoting about a pin on a drive plate integral in rotation with the mast, and to which the pitch control rod is hinged, the bellcrank being also hinged to a link rod connected to the pitch change lever.

  • Constant velocity drive rotary-wing aircraft rotor with torque splitting differential
    Patent number: 6712313
    Abstract: A constant velocity drive mechanism of a rotary-wing aircraft rotor, comprises a torque splitting differential mechanism, comprising a driving disc integral in rotation with a rotor mast and connected to each of two driven discs either side of the driving disc, by a least one connecting pin hinged to each of the discs by one of three ball joint connections. Each of the driven discs is connected to a hub of the rotor by at least one of two driving devices, each of which is also hinged to the hub, so as to drive the hub in rotation about a geometrical axis which can be inclined in all directions about the axis of rotation of the mast.
