  • Patent number: 10288399
    Abstract: A tool is provided for characterizing a blade geometry. The tool includes a first component attachable to a blade root of a blade and a second component attachable to leading and trailing edges of the blade at a blade tip and at multiple stations defined along a span-wise dimension of the blade. The second component is configured for characterization of a chord length of the blade at the blade tip and at the multiple stations. The first and second components are respectively configured for cooperative optical characterization of a sweep and a twist angle of the blade at the blade tip and at the multiple stations.

  • Patent number: 10183341
    Abstract: A system for transferring a hole pattern from a first component to a second component configured to couple to the first component is provided including a contour plate having a drill plate with a hole pattern substantially identical to the hole pattern of the first component. The position of the drill plate is adjustable to match the hole pattern of the drill plate with the hole pattern of the first component. A slidable fixture configured to support the second component is movable to align the second component with the drill plate such that the hole pattern of the drill plate in relation to the second component matches the hole pattern of the drill plate in relation to the hole pattern of the first component. The hole pattern of the drill plate is used to create a hole pattern in the second component matching the hole pattern of the first component.

  • Publication number: 20180104751
    Abstract: A tool for removing a bushing from a workpiece includes a tool body, a first reference, and a second reference for positioning the tool body on a workpiece. A saw slot is defined through the tool body to provide access to the workpiece for a saw blade. A saw guide is proximate the saw slot, the saw guide arranged to position a saw blade in a cutting plane spaced apart from the workpiece for removing a segment of a bushing fixed to the workpiece relative to the first and second references.

  • Publication number: 20180093761
    Abstract: A bond fixture includes a first frame defining a chamber configured to receive a leading edge of a rotor blade and a second frame pivotally coupled to the first frame. The second frame is movable between a first position and a second position. In the second position, the second frame restricts movement of the bond fixture relative to the rotor blade. At least one supporting assembly extends from the first frame towards the chamber. The at least one supporting assembly is adjustable to apply a pressure to an adjacent surface of the rotor blade.
