Abstract
An airfoil () including an internal cooling circuit () to direct cooling fluid () through an interior of the airfoil. The airfoil also includes a trailing edge (') defining plugged holes () and cooling holes () along a radial direction (). A selective group () of the cooling and plugged holes are based on a reduced cooling fluid requirement at the trailing edge (′) resulting from an improved thermal barrier coating (). A process () is also provided including removing () an airfoil from service in a gas turbine engine and adding or improving () a thermal barrier coating on the airfoil. The process also includes selectively () plugging holes in the airfoil in response to a reduced cooling fluid required through the airfoil as a result of the added or improved thermal barrier coating.
