Abstract: An elastomeric bearing has a first end interface, a second end interface, an activation element disposed between the first end interface and the second end interface, and a clutch component disposed between the activation element and the second end interface. A method of operating an elastomeric bearing includes providing a first end interface, providing a second end interface, providing an activation component between the first end interface and the second end interface, providing a clutch component between the activation component and the second end interface, and rotating the first end interface relative to the second interface to cause rotation of the clutch component relative to the second end interface.

Abstract: A universal-joint cross assembly includes a cross. Four compression rings are mounted at terminal positions of the cross. Each of the four compression rings is positioned at a 90° interval relative to adjacent ones of the four compression rings. The universal-joint cross assembly includes four inner balls. Each of the four inner balls is fixed to one of the four compression rings and forms a portion of a spherical bearing.

Abstract: An exemplary blade lock for a tiltrotor aircraft to enable and disable a folding degree of freedom and a pitching degree of freedom of a rotor blade assembly includes a link pivotally connected to a lever and a bellcrank, where the link is in a center position when the lever is in a locked position disabling the folding degree of freedom and the lever is secured in the locked position when the link is positioned in an over-center position.

Abstract: An inboard bearing attachment for carrying centrifugal force (“CF”) loads in a rotor blade assembly of a rotorcraft includes a CF fitting having a curved surface and a shear bearing retainer aligned with the curved surface. A mounting flange connected to either the CF fitting or the shear bearing retainer is used to mount the inboard bearing attachment to a yoke.
