Abstract: A method for manufacturing a turbine nozzle having a non-linear cooling conduit is disclosed. In one embodiment, a method includes: providing a turbine nozzle. The turbine nozzle includes: an airfoil, a cavity, having an inner surface, located within the airfoil, at least one endwall adjacent the airfoil, and a fillet region connecting the airfoil and the endwall. The fillet region also includes an outer surface. The method also includes: forming a non-linear cooling conduit within the fillet region and adjacent the outer surface of the fillet region of the turbine nozzle. The forming of the non-linear cooling conduit includes curved drilling through a portion of the outer surface of the fillet region of the turbine nozzle.
