  • Patent number: 10336446
    Abstract: A bearing sleeve assembly includes a rigid inner element having a cylindrical inner diameter bore and an outer surface that is non-cylindrical. Also included is a rigid outer element spaced radially outwardly from the rigid inner element, the rigid outer element comprising a cylindrical member with a uniform cross-section that forms a ring with an inner-diameter surface and an outer-diameter surface, the outer element's inner-diameter surface and the non-cylindrical outer surface of the inner element defining a non-uniform annulus therebetween. Further included is an elastomeric core disposed between the rigid inner element and the rigid outer element within the non-uniform annulus, the elastomeric core having a first thickness at a first location and a second thickness at a second location, the first thickness being greater than the second thickness.
    Type: Grant
    Filed: November 4, 2016
    Date of Patent: July 2, 2019
    Assignee: SIKORSKY AIRCRAFT CORPORATION

  • Patent number: 9428268
    Abstract: A flexbeam for a rotor blade is provided and includes a first end coupled to a body of the rotor blade and a second end coupled to a flap disposed along a trailing edge of the body to pitch about a pitching axis defined along a span of the body and a flexbeam body extending from the first end to the second end and being configured to retain the flap under a first loading and being flexible about the pitching axis.

  • Patent number: 8858179
    Abstract: A rotor control system operatively linked to a plurality of rotor blades includes a swashplate assembly having a stationary member and a rotating member. A blade attachment member is operatively connected to the plurality of rotor blades and a control horn is operatively connected to the blade attachment member and one of the plurality of rotor blades. At least one hydraulic actuator member is operatively coupled to the control horn and at least one hydraulic actuator element is operatively coupled to the swashplate assembly and the at least one hydraulic actuator member. The at least one hydraulic actuator member transmits control signals from the swashplate assembly to the one of the plurality of rotor blades through the at least one hydraulic actuator member.
