  • Bladed disk assembly method and impact device
    Patent number: 7975354
    Abstract: A bladed disk assembly device includes a horizontal arm and a fixed vertical pivot bar that is perpendicularly attached to a first end of the horizontal rotating arm via a sliding coupling mechanism. A vibratory impact device is attached to a second end of the horizontal rotating arm and generates a vibrating motion via a power source. An impact shoe is attached to the vibratory impact device and drives a blade into a disk slot.
    Type: Grant
    Filed: February 8, 2007
    Date of Patent: July 12, 2011
    Assignee: United Technologies Corporation

  • Torque wrench reversal extension
    Publication number: 20080028898
    Abstract: An extension tool for a torque wrench has a drive end associated with a fastener and a driven end associated with the torque wrench that face 180° from each other. The drive end defines an axis of rotation and the driven end is co-axial with the axis of rotation, which eliminates the need for any type of torque correction due to a change in moment arm length. The extension tool also includes a hand support that allows an installer to apply a load in a direction along the axis of rotation as the torque wrench drives the fastener into place.
