A turbine vane for use in a gas turbine engine, the vane including an airfoil portion and an endwall in which fillets extend around the airfoil at the junction to the endwall. A row of film cooling holes that connects to a cooling air supply cavity on the outer side of the endwall and open into breakout holes that are located in the fillets discharge film cooling air into the fillet. The breakout holes extend around the leading edge in the fillet and extend along the pressure side fillet and the suction side fillet just past the leading edge region to discharge film cooling air into the fillets. The film cooling holes are straight holes and are aligned with the curvature of the fillet at the midpoint height of the fillet. |
