    摘要: A turbine nozzle vane includes pressure and suction sidewalls extending between leading and trailing edges. The vane includes a pair of integral ribs defining three internal cooling channels between the leading and trailing edges. Rows of film cooling holes extend through the sidewalls, and three rows in the pressure side are inclined along the span of the airfoil at different slopes.

    摘要: A gas turbine engine nozzle segment includes at least two circumferentially adjacent vanes joined together along an interface between the vanes. Each of the vanes includes a hollow airfoil disposed between radially inner and outer band panels and a cooling air intake duct leading to a hollow interior of the airfoil for directing cooling air into the hollow interior. The intake duct has a duct wall protruding radially outward from the outer band panel and at least one impingement cooling hole disposed through the intake duct wall and circumferentially and radially inwardly angled. A flange portion extends circumferentially along the outer band panel and an opening in the flange portion is in fluid communication with the intake duct. The hollow airfoil, radially inner and outer band panels, intake duct wall, and flange portion are integrally formed and, preferably, integrally cast such that the vane is a single piece integrally cast vane.
