  • Patent number: 8523518
    Abstract: Systems, methods, and apparatus for linking machine stators are provided. A bracket may be utilized to link adjacent stators within a machine, for example, a turbine. The bracket may include a body portion, a first plurality of extensions, and a second plurality of extensions. The body portion may include a first edge operable to align with a base of a first stator and a second edge opposite the first edge and operable to align with a base of a second stator. The first plurality of extensions may extend from the first edge and may be operable to align with at least one corresponding groove on the base of the first stator. The second plurality of extensions may extend from the second edge and may be operable to align with at least one corresponding groove on the base of the second stator. When utilized to link the first stator and the second stator, the bracket may facilitate a reduction of vibrations in the first stator and the second stator.

  • Patent number: 7854583
    Abstract: A compressor having a plurality of vane units each having at least one airfoil projecting from the base. Each base has a groove, so that when the vane units are disposed circumferentially adjacent, the grooves of the respective vane units are circumferentially aligned. A metal strip is disposed in the groove of a plurality of adjacent vane units to link the vane units forming a more rigid ring of vanes that are less susceptible to vane motion, e.g., caused by pressure fluctuations within the compressor of a gas turbine.
