ABSTRACT:
A turbine vane for use in a gas turbine engine having high turbine inlet temperatures is disclosed. Film cooling is provided at the leading edge of the vane airfoil by cooling air which flows through leading edge holes from a hollow cavity in the airfoil section. Film cooling air is also provided through wall holes along the suction and pressure sides of the airfoil. A U-shaped insert having a pressure leg and a suction leg is disposed within the hollow cavity to isolate the leading edge holes from the wall holes. When the cavity is pressurized, the legs are each urged against corresponding seal ribs which extend from the cavity wall to effectively isolate the leading edge holes.
