  • Spinner shaft attachment
    Patent number: 10647410
    Abstract: A spinner assembly includes a cone-shaped member having a plurality of blade openings. The cone-shaped member is receivable about a shaft at a first location. A bulkhead frame is connected to the cone-shaped member. At least one strut is configured to couple the bulkhead frame to the shaft at a second location. The at least one strut includes at least one arm having a longitudinal rigid member and at least one flexure region that defines an axis about which the at least one arm bends.

  • Rotorcraft rotor assemblies
    Patent number: 10604246
    Abstract: An attachment assembly for coupling a rotary blade to a hub includes a hollow shear pin, a nut cap, and a tensioning fastener. The hollow shear pin defines an attachment axis. The nut cap abuts the shear pin along the attachment axis. The tensioning fastener is seated within the shear pin, is threadably engaged to the nut cap, and has an axial length that is smaller than an axial length of the shear pin to fix a rotary blade to a rotor assembly within a profile of the rotary blade.
