  • Patent number: 10746284
    Abstract: A gearbox for a rotary wing aircraft including a sump, a primary lubricant reservoir fluidically connected to the sump, one or more primary lubricant jets fluidically connected to the primary lubricant reservoir, an auxiliary lubricant reservoir fluidically connected to the sump, one or more auxiliary lubricant jets fluidically connected to the auxiliary lubricant reservoir, and at least one valve selectively fluidically connecting the sump and the primary lubricant reservoir based on a first lubricant pressure and the sump and the auxiliary lubricant reservoir based on a second lubricant pressure at the at least one valve.
    Type: Grant

  • Patent number: 10494089
    Abstract: A hanger bearing assembly for a shaft assembly includes a plurality of bearing elements arranged around a circumference of a shaft assembly, each bearing element having a bearing element diameter. A bearing inner race is positioned between the plurality of bearing elements and the shaft assembly and extends circumferentially about the shaft assembly. The bearing inner race includes an outer wall interactive with the plurality of bearing elements. The outer wall has a linear profile extending in an axial direction. A bearing outer race is positioned radially outboard of the plurality of bearing elements and extends circumferentially about the shaft assembly. The bearing outer race includes an inner surface interactive with the plurality of bearing elements and having a curvilinear inner surface profile extending in the axial direction.

  • Publication number: 20190276143
    Abstract: A blade retention system includes a rotor hub including a plurality of radial arms, and a blade retention yoke associated with the rotor hub and one of the plurality of radial arms. The blade retention yoke is rotatable relative to the rotor hub and the radial arm. A tension torsion device connects the radial arm to the blade retention yoke to restrict radial movement of the blade retention yoke relative to the radial arm.

  • Patent number: 9145926
    Abstract: A torque limiting device includes a first portion connected to a first rotatable component. The first portion has a flange extending radially outward therefrom. A second portion includes a plurality of pre-loaded axial springs and is coupled to a second rotatable component. The second portion is arranged adjacent opposing surfaces of the flange. The second portion is configured to apply a biasing force to the flange to selectively couple the first rotatable component and the second rotatable component.
