Abstract
A cooled turbine engine component is made by providing first and second pieces respectively having first and second surfaces. At least one circuit is formed in at least one of the first and second surfaces. A first plurality of apertures is provided in the first piece to form inlets to the at least one circuit. A second plurality of apertures is provided in the second piece to form outlets to the at least one circuit. A combination of the first and second pieces is assembled and integrated.
Claims21
A method for manufacturing a turbine engine component having one or more internal feed passageways, one or more external walls, and one or more outlet passageways through the one or more external walls, the method comprising:
- cutting one or more cuts in a workpiece to create a plurality of separate subpieces each having one or more cut surfaces;
- providing a plurality of apertures in the one or more cut surfaces;
- after said providing, reassembling a combination of said subpieces or of like subpieces;
- integrating the combination;
- and
- machining at least portions of the internal feed passageways so that at least some of said outlet passageways are formed by combinations of said apertures from separate ones of said subpieces, wherein said machining said at least one internal feed passageway is generally transverse to said plurality of apertures in each of said pairs so as to ultimately intersect therewith.

- providing a plurality of apertures in the one or more cut surfaces;
- reassembling a combination of said subpieces or of like subpieces;
- integrating the combination;
- and
- machining at least portions of the internal feed passageways so that at least some of said outlet passageways are formed by combinations of said apertures from separate ones of said subpieces,
- wherein:
- the component includes an airfoil having a pressure side surface and a suction side surface, at least some of said outlet passageways have an outlet along the pressure side or suction side surface;
- a junction between a first of said subpieces and a second of said subpieces is locally generally parallel to one of said pressure and suction side surfaces;
- and
- a junction between said first of said subpieces and a third of said subpieces is locally generally parallel to the other of said pressure and suction side surfaces.
