    Date of Patent: March 29, 2016
    Assignee: UNITED TECHNOLOGIES CORPORATION
    Inventor: Andrew H. Harris
  • Gas turbine engine exhaust component and manufacturing method of same
    Patent number: 8015820
    Abstract: A gas turbine exhaust component, such as an exhaust nozzle, is provided that includes circumferential ribs arranged along a longitudinal axis. Longitudinal strakes are supported by the circumferential ribs and arranged about the longitudinal axis. Fastening elements are used to secure the longitudinal strakes to one another to provide a desired exhaust component contour. In one example, fastening elements are used to secure the longitudinal strakes to the circumferential ribs using a bracket. The longitudinal strakes are preformed into the desired exhaust component contour, using low cost forming methods. The longitudinal strakes are formed to fit the circumferential ribs and provide the desired exhaust component contour. The longitudinal strakes are secured to one another to maintain the desired exhaust component contour. The longitudinal strakes may be provided by a low cost steel, in one example.
