Abstract: A quick change height adjustment mechanism allows a reel stand to accommodate differently sized storage spools. The mechanism includes a plate, a locking pin and a pivot pin. The plate forms a cavity into which a post is seated and has at least one space which receive a spindle of the spool. The locking pin extends from the plate and into the cavity. The locking pin is vertically spaced from, and positioned on a first side of, a centerline of the plate. The pivot pin is attached to the plate, is vertically spaced from, and positioned on a second, opposite side of, the centerline. The pivot and locking pins are positioned on opposite sides of the post. In use, the plate can be pivoted relative to the post around pivot pin to engage or disengage the locking pin with holes in the post.

Abstract: A rotor blade system includes a first hub assembly having a first set of rotor blades and rotatably attached to a rotor mast, a second hub assembly having a second set of rotor blades and rotatably attached to the rotor mast, the second hub assembly being positioned at a space relative to the first hub assembly, a torque splitter device engaged with both the first hub assembly and the second hub assembly, and a locking device operably associated with the torque splitter device. The method includes rotating the first hub relative to the second hub via the torque splitter until the first set of rotor blades align with the second set of rotor blade about a common horizontal axis.

Abstract: A propulsion system for a tiltrotor aircraft includes an engine supported by the airframe and a fixed gearbox operably coupled to the engine. Inboard and outboard pedestals are supported by the airframe and positioned above the wing. A pylon assembly is rotatably coupled between the inboard and outboard pedestals. The pylon assembly includes a spindle gearbox having an input gear, a mast operably coupled to the input gear and a proprotor assembly operable to rotate with the mast. The spindle gearbox is rotatable about a conversion axis to selectively operate the tiltrotor aircraft between helicopter and airplane modes. A common shaft, rotatable about the conversion axis, is configured to transfer torque from an output gear of the fixed gearbox to an input gear of the spindle gearbox. Each of the inboard and outboard pedestals includes a spherical bearing providing a self-aligning coupling with the pylon assembly.
