Abstract
A turbine vane includes an airfoil body having a leading edge, a trailing edge and a smooth outer surface. A cutout is included within at least one of the leading edge and the trailing edge, the cutout removing a predetermined area of the airfoil body. A coupon is coupled in the cutout to replace the predetermined area of the airfoil body. The coupon includes a first corrugated surface on at least a portion of an outer surface thereof. The coupon allows for the addition of advantageous wake mixing and cooling efficiencies to preexisting vanes.

A turbine vane comprising:
- an airfoil body having a leading edge, a trailing edge and a smooth outer surface;
- a cutout within at least one of the leading edge and the trailing edge, the cutout removing a predetermined area of the airfoil body;
- and
- a coupon coupled in the cutout to replace the predetermined area of the airfoil body, the coupon including a first corrugated surface on at least a portion of an outer surface thereof.
A coupon for replacing a cutout of a predetermined area in an airfoil body of a turbine vane, the airfoil body having a leading edge, a trailing edge and a smooth outer surface, the cutout within at least one of the leading edge and the trailing edge of the airfoil body, the coupon comprising:
- a first corrugated surface on at least a portion of an outer surface thereof.
A non-transitory computer readable storage medium storing code representative of a coupon for replacing a cutout of a predetermined area in one of a leading edge or a trailing edge in an airfoil body of a turbine vane, the coupon physically generated upon execution of the code by a computerized additive manufacturing system, the code comprising:
- code representing the coupon, the coupon including:
- a first corrugated surface on at least a portion of an outer surface thereof.
