Abstract: A bearing assembly for coupling a proprotor blade to a yoke in a proprotor system. The bearing assembly is positionable within an inboard pocket of a blade arm of the yoke. The proprotor system is operable for use on a tiltrotor aircraft having helicopter and airplane flight modes. The bearing assembly includes a centrifugal force bearing and a shear bearing having an inboard beam coupled therebetween. The centrifugal force bearing has a mating surface, a lateral movement constraint feature and at least one radially extending anti-rotation feature. The inboard beam has a mating surface in a contact relationship with the mating surface of the centrifugal force bearing, a lateral movement constraint feature operably associated with the lateral movement constraint feature of the centrifugal force bearing and at least one radially extending anti-rotation feature that corresponds with the at least one radially extending anti-rotation feature of the centrifugal force bearing.

Abstract: A magnetic spacer system for a spinner of a rotorcraft includes a first ring of a plurality of magnets secured to the spinner and having an inner surface facing radially inward, and a second ring of a plurality of magnets secured to a nacelle of the rotorcraft and having an outer surface facing radially outward. The first and second rings of multiple magnets are arranged concentrically, and a portion of the inner surface of the first ring of a plurality of magnets and a portion of the outer surface of the second ring of a plurality of magnets have the same polarity to repel one another. In other aspects, the magnetic spacer system may be replaced by a low-friction system.

Abstract: A coupling system is described that allows users to avoid having to manipulate two tools at the same time while reaching around to both sides of the coupled components. A lock plate can rest above one or more holes passing through (and for joining together) the components. A blade pin with a partially hollow cylinder can be inserted through holes in the lock plate and at least partially through the holes. A blade bolt can be inserted into the holes and the cylinder from the other side. The blade bolt can comprise an o-ring that engages with an inner diameter of a portion of the cylinder and holds the parts together with an interference fit. A portion of the bolt can extend through the top of the holes, and a washer and nut can be attached to or about a threaded portion of the bolt. During each state of installation a user will not have to reach to both sides of the system while manipulating multiple tools.

Abstract: A tiltrotor controls shield having a blade or wire substructure under a fragile spinner fairing improves bird strike durability. The present disclosure discloses a spinner wind fairing with a shield structure disposed thereunder for providing protection to the proprotor assembly components. The shield structure can segment a projectile, such as a bird, that penetrates the spinner fairing into a series of smaller and lower energy elements spread across a wider area, such that the rotor components can withstand the impact of the smaller elements without damage.

Abstract: A spindle bearing assembly for a rotor blade, the assembly having a shaft extending from a hub and a housing for coupling the blade to the shaft. A ring is coaxial with the shaft and has a wall with a tapered external surface that narrows toward the outboard direction. The ring can be axially translated adjacent a tapered internal surface of the housing that also narrows toward the outboard direction. A spindle bearing coaxial with the shaft has a central aperture through which the shaft extends, the spindle bearing extending between the wall and the shaft. Threaded fasteners couple the ring to the housing, and rotation of the fasteners in a selected direction causes axial translation of the ring in the outboard direction, the engagement of the tapered surfaces causing the wall to move radially inward for creating an interference fit between the spindle bearing and the wall.
