Abstract

Turbine components having cooling slots and methods of producing the same are provided. The turbine components include an airfoil (144) having a pressure side and a suction side (156,158), passages within the airfoil, and slots (160) open to the pressure side adjacent the trailing edge (147). The slots are in fluidic communication with the passages and configured to discharge a cooling fluid therefrom. The slots are defined by a slot upper side wall, a slot lower side wall, a pressure side surface, and a slot bottom. The pressure side surface includes a pressure side upper wall fillet coupled to the slot upper side wall and a pressure side lower wall fillet coupled to the slot lower side wall. Edges of the pressure side upper and lower wall fillets have a combined dimension equal to or greater than 30 percent of a total dimension of the pressure side surface.
