Abstract
A cooling system () for a turbine airfoil () of a gas turbine engine, wherein the airfoil () has a bowed configuration is disclosed. The airfoil () may be configured such that the leading edge () or trailing edge (), or both, may have midsections that are positioned further upstream than outer ends of the leading and trailing edges (). One or more cooling channels () of the cooling system () may have a larger cross-sectional area proximate to an end of the airfoil () than at a midspan location. One or more cooling channels () may have one or more corner blockers () that extend chordwise in the cooling channel () and extend from a corner () toward a centerline axis (), thereby reducing a cross-sectional area of the cooling channel (). The corner blockers () may be positioned within the cooling system () to maintain the flow of cooling fluids through the airfoil () within desired design parameters.
