  • Flange cooled turbine nozzle
    Patent number: 8292573
    Abstract: A turbine nozzle includes outer and inner bands bounding nozzle vanes. The outer band includes an aft flange. An impingement baffle bridges the outer band and aft flange at the root thereof to provide impingement cooling.
    Type: Grant
    Filed: April 21, 2009
    Date of Patent: October 23, 2012
    Assignee: General Electric Company
    Inventors: Mark Broomer, Robert Francis Manning, Haidong Liu
  • Divergent turbine nozzle
    Patent number: 8281604
    Abstract: A turbine nozzle includes a row of vanes extending radially in span between inner and outer bands. The vanes include opposite pressure and suction sidewalls and opposite leading and trailing edges. Each vane includes an inner pattern of inner cooling holes and an outer pattern of outer cooling holes distributed along the leading edge. The inner and outer holes diverge toward the corresponding inner and outer bands to preferentially discharge cooling air.
