Patent number: 9694440Abstract: 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.Type: GrantFiled: October 22, 2010Date of Patent: July 4, 2017Assignee: United Technologies CorporationInventors: James J. Moor, Herbert A. Chin, Greg Czeladko, Gene A. Danko, Andrew L. Haynes, Wangen Lin, Vincent Nevins, Robert P. Schaefer, Eberhardt Privitzer

Patent number: 8613138Abstract: 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.Type: GrantFiled: March 19, 2010Date of Patent: December 24, 2013Assignee: United Technologies CorporationInventors: Herbert A.

Patent number: 8611732Abstract: 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.

Patent number: 8437628Abstract: 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.Type: GrantFiled: January 30, 2012Date of Patent: May 7, 2013Assignee: United Technologies CorporationInventors: Wangen Lin, James J.
