METHOD AND CASTING CORE FOR FORMING A LANDING FOR WELDING A BAFFLE INSERTED IN AN AIRFOIL

Abstract:

A method and casting core for forming a landing for welding a baffle inserted into an airfoil are disclosed, wherein the baffle landing of the blade or vane is formed in investment casting by the casting core rather than by wax, reducing tolerances and variability in the location of the baffle inserted into the cooling cavity of airfoil when the baffle is welded to the baffle landing.
