  • Tie shaft for gas turbine engine and flow forming method for manufacturing same
    Patent number: 9291057
    Abstract: A method is disclosed for manufacturing a tie shaft for aero or land based gas turbine engine. The method includes flow forming a tie shaft preform to produce a tie shaft. In one example, the tie shaft includes a nickel alloy cylindrical wall having a length to diameter ratio of at least 6:1, wherein the diameter is an average outer diameter. The wall includes a minimum effective strain of 0.3 in/in (7.6 mm/mm), and a grain size is in the range of G4 to G16 per ASTM E112. The wall includes a roll formed threaded surface having a thread roughness of less than 1260 ?in (32 microns).

  • A METHOD OF FABRICATING A ROTOR OF A TURBOFAN ENGINE
    Publication number: 20150306713
    Abstract: A method of fabricating a disk assembly for a turbofan engine is disclosed and includes the steps of forming a first and second disk and welding the second disk to the first disk to form a weld joint. A portion of the first disk and the second disk are removed along the weld joint on at least one surface to reduce a size of a heat affected zone and substantially reduce possible formation of material inconsistencies.

  • Installation of downhole electrical power cable and safety valve assembly
    Patent number: 7195072
    Abstract: The present invention generally provides apparatus and methods for removing liquid from a well. In one embodiment, a cable and subsurface safety valve assembly is used with a downhole pumping system to remove water from the well. The cable and subsurface safety valve assembly allows the cable to run from surface to a pumping unit while maintaining safety valve integrity. In another aspect, the cable and subsurface safety valve assembly may be adapted for use with an existing production tubing.
