  • Publication number: 20070069478
    Abstract: A leakage seal for use in a gas path between two relatively rotatable members of a gas turbine comprises a foil layer and a cloth layer. The foil layer has two expansive surfaces, a single one of which is covered by the cloth layer. The leakage seal has a proximal end, a distal end, and a generally flat region between the proximal and distal ends. The proximal end is attached to an associated one of the turbine members. The distal end diverges from the generally flat region so as to define a curved hook, along which the cloth portion is wrapped over the foil layer, when the distal end is viewed in cross-section.

  • Publication number: 20070033941
    Abstract: As used to connect a combustor of a gas turbine to a stage of the gas turbine, a transition piece has a generally tubular body, an inlet to receive hot gases from the combustor, and an outlet to discharge the gases. The transition piece has a frame, which surrounds the outlet, and two mounting connectors, which are spaced from each other and which extend from the frame, away from the outlet. The mounting connectors are welded to a pedestal, which is formed unitarily with the frame so as to extend partially but not completely around the outlet.
