  • Foldable rotor blade assembly
    Patent number: 10618632
    Abstract: An adapter for a rotor blade assembly including a support member having an outboard surface and an inboard surface; an outboard feature extending laterally from the outboard surface of the support member and including a first lug and a second lug; an inboard feature extending laterally from the inboard surface of the support member and including a first arm and a second arm. The outboard feature and the inboard feature are configured such that a plane defined by an attachment surface of at least one of the first lug and the second lug is non-parallel to a plane defined by an attachment surface of at least one of the first arm and the second arm.
    Type: Grant

  • Elastomeric bearing having tapered layers
    Patent number: 9334048
    Abstract: A rotor hub for an aircraft that includes a yoke, a rotor mast; and a hub spring assembly. The hub spring assembly includes an upper outer member; an upper inner member; and an upper spring member having a plurality of elastomeric layers and shim layers sandwiched between the upper outer member and the upper inner member, the shim layers being tapered such that a thickness of each shim layer is smaller at a side portion as compared to the thickness of the shim at a center portion.
