Patent abstract
A turbine airfoil usable in a turbine engine and having at least one cooling system. At least a portion of the cooling system may be positioned in an endwall attached to the turbine airfoil. The endwall may include a submerged endwall cooling channel at the intersection between the generally elongated airfoil and the first endwall. The second endwall attached to the endwall on an end generally opposite to the first endwall may have a submerged endwall cooling channel as well. The submerged endwall cooling channels may include film cooling orifices to form vortices of cooling fluids to enhance cooling capacity of the cooling system of the turbine airfoil.
