Publication number: 20230392520Abstract: A method is provided for disassembling a gas turbine engine. The gas turbine engine includes a compressor section, a combustor section, a turbine section, a static structure and a bypass duct. The static structure houses and supports the compressor section, the combustor section and the turbine section. The static structure includes a turbine support structure. The bypass duct includes an inner duct wall, an outer duct wall and a bypass flowpath formed radially between the inner duct wall and the outer duct wall. The outer duct wall extends axially along the static structure and overlaps the turbine support structure. During the method, the turbine support structure is removed from the gas turbine engine while the outer duct wall remains installed.Type: ApplicationFiled: August 14, 2023Publication date: December 7, 2023Inventors: Carlo S. Porco, Geoffrey Henriksen, Jason Wedemire, Anthony Mathias, Michael Hunze, Louis Lavoie, Marven Paynter, Dennis Wilkinson

Aircraft engine repair tool and method for removal and installation of a rotor in an aircraft engine
Patent number: 11807398Abstract: Methods and tools for facilitating the installation and/or removal of a rotor on a shaft of a gas turbine engine are provided. The tool includes a stabilizer attachable to the shaft and including a first guide counterpart. The tool also includes a holder attachable to the rotor and including a second guide counterpart for engagement with the first guide counterpart of the stabilizer. Engagement of the first and second guide counterparts guides movement of the holder relative to the stabilizer along a guide axis and prevents movement of the holder relative to the stabilizer transverse to the guide axis.Type: GrantFiled: December 12, 2022Date of Patent: November 7, 2023Assignee: PRATT & WHITNEY CANADA CORP.Inventors: Geoffrey Henriksen, Anthony Mathias, Jason Wedemire -
Publication number: 20230304419Abstract: An aircraft engine repair tool for installing and/or removing a mid turbine frame from a gas turbine engine is provided. The tool includes a stabilizer configured to support a shaft via a load path different from a load path provided by the mid turbine frame rotatably supporting the shaft about a rotation axis. The tool includes a holder attachable to the mid turbine frame, and a guide movably engageable with the shaft and attachable to the holder. The guide guides movement of the holder and of the mid turbine frame relative to the shaft along the rotation axis, and prevents movement of the holder and the mid turbine frame relative to the shaft transverse to the rotation axis when the mid turbine frame is released from the support structure and attached to the holder, and when the holder is attached to the guide.Type: ApplicationFiled: May 15, 2023Publication date: September 28, 2023Inventors: Carlo PORCO, Geoffrey HENRIKSEN, Jason WEDEMIRE, Anthony MATHIAS, Michael HUNZE, Louis LAVOIE, Marven PAYNTER, Dennis WILKINSON
