  • Patent number: 9694440
    Abstract: An example method of attaching an airfoil for an integrally bladed rotor includes placing a support collar in an installed position around at least a leading edge and trailing edge of an airfoil stub to be repaired in an integrally bladed rotor. The support collar and the airfoil stub together have a midline that is positioned between opposing, laterally outer surfaces of the airfoil stub when the support collar is in the installed position. The method performs linear friction welding to add a replacement airfoil to the airfoil stub.

  • Patent number: 8925200
    Abstract: An example method of repairing an airfoil includes the steps of securing additional material to a worn airfoil and limiting movement of the additional material with a guide. The method alters some of the additional material to form a desired airfoil contour. Another example method of forming a portion of an airfoil includes the steps of securing additional material to an airfoil, limiting movement of the additional material with a guide, and altering some of the additional material to form a desired airfoil contour.

  • Patent number: 8613138
    Abstract: A method is provided for repairing a damaged rotor blade on an integrally bladed rotor by removing a damaged portion of a damaged blade leaving a blade stub extending outwardly from the disk and performing a linear friction welding operation to attach a replacement blade segment to the blade stub. The rotor may be disposed operation using a linear friction welding apparatus. The method includes disposing a support collar about the blade stub and securing the support collar to the linear friction welding apparatus prior to a commencement of the bonding operation. A lower surface of the support collar is contoured to mate with a portion of an outer circumference surface of the rotor disk.

  • Patent number: 8611732
    Abstract: A device and method for locally heat treating at least one airfoil in an integrally bladed rotor device. A pair of IR heat sources are positioned to direct IR heat rays in the direction where local heat treatment is required. A pair of parabolic mirrors are positioned to direct the IR heat rays on to the metal component. The heat treating is useful after welding the airfoil on to the rotor device.

  • Patent number: 8479391
    Abstract: A method of repairing an integrally bladed rotor includes the steps of placing a support collar around at least a leading and trailing edge portions of the blade stub, and performing linear friction welding to add a replacement airfoil to the blade stub. The linear friction welding is generally along a direction between the leading and trailing edges. In addition, the support collar leading and trailing edge portions are connected together.

  • Patent number: 8437628
    Abstract: A process for heat treating selected portions of an integrally bladed rotor (IBR) having a plurality of blades, the process using an IBR on a fixture having a rotor engaging portion that moves the IBR into an environmental chamber. An IR heater is placed on one of the IBR blades and heat treated after air has been removed from the chamber and an inert gas is added. The IR heater is lifted from the blade and indexed to position another blade on the IBR. The process is repeated until all the IBR blades are heat treated.

  • Patent number: 8394215
    Abstract: A process for repairing cracks in a workpiece, such as a turbine engine component, comprises the steps of: providing a workpiece having a crack to be repaired; applying a nickel or cobalt base alloy material to a root of the crack in an amount sufficient to fill a portion of the crack; subjecting the workpiece with the nickel or cobalt base alloy material to a first heat treatment at a temperature in the range of from about 1950 to 2300° F. for a time period in the range of from about 5.0 to 30 minutes; applying a weld material to the crack; and subjecting the workpiece with the weld material to a second heat treatment.

  • Publication number: 20100243614
    Abstract: A method of repairing a hole in a work piece includes mechanically constraining donor plates against a work piece. Constraint plates keep donor plates flush against the work piece during conductive heat resistance welding. By constraining the donor plates, the molten mixture produced by conductive heat resistance welding cannot escape the hole and a weldment substantially free of voids is formed.
