  • Patent number: 6190120
    Abstract: A plurality of passages are spaced one from the other along the length of a trailing edge of a nozzle vane in a gas turbine. The passages lie in communication with a cavity in the vane for flowing cooling air from the cavity through the passages through the tip of the trailing edge into the hot gas path. Each passage is partially turbulated and includes ribs in an aft portion thereof to provide enhanced cooling effects adjacent the tip of the trailing edge. The major portions of the passages are smooth bore. By this arrangement, reduced temperature gradients across the trailing edge metal are provided. Additionally, the inlets to each of the passages have a restriction whereby a reduced magnitude of compressor bleed discharge air is utilized for trailing edge cooling purposes.

  • Patent number: 6126389
    Abstract: An inner shroud 22 is coupled to an outer shroud 20 which receives cooling air through an inlet 54 for flow to the inner shroud. The inner shroud includes a wall 42 which defines in part the hot gas path 16 and a plurality of cavities 44 on an opposite side of the wall. The inner shroud includes a cover 40 having depending compartments 52 with apertures 56 through the floor of the compartments. When the cover overlies the inner shroud body, the compartments are received in the cavities and cooling air from the inlet flows into the compartments and through the apertures for impingement cooling of the inner shroud wall. Spent cooling air exits the inner shroud through passages 45 through circumferential and/or axial facing side walls of the inner shroud and/or the wall of the inner shroud defining the hot gas path.
