Abstract: A turbine rotor blade is additively manufactured and includes an airfoil body with a radially extending chamber for receiving a coolant flow, a tip end at a radial outer end of the airfoil body, and a shank at a radial inner end of the airfoil body. The radially extending chamber extends at least partially into the shank to define a shank inner surface. An integral impingement cooling structure is within the radially extending chamber. The integral impingement cooling structure allows an exterior surface of a hollow body thereof to be uniformly spaced from the airfoil inner surface despite the curvature of the chamber. The turbine rotor blade has impingement cooling throughout the blade.

Abstract: A passage incorporated into an additively manufactured object, the object and a related method are disclosed. The object has an additive manufacture build direction. The passage includes: a first portion aligned along an axis oriented less than approximately 45° from the build direction; and a second portion aligned along an axis oriented greater than approximately 45° from the build direction, the second portion including at least one self-supporting top surface portion including at least one edge aligned no greater than approximately 45° from the build direction. The passage having varying cross-sectional shape along a non-linear length accommodates additive manufacture regardless of build direction.

Abstract: A protection system for preventing foreign material from lodging in a channel between and/or damage to adjacent ceramic core features during a core processing operation is disclosed. The system includes a gasket sized and shaped to self-lock within the channel and prevent foreign material from lodging within the channel during the core processing operation. A method may include determining a geometrical characteristic of the channel and adjacent ceramic core feature; fabricating a gasket to fit and self-lock within the channel; positioning the gasket within the channel; and performing the core processing operation. The gasket prevents the foreign material from lodging in the channel, reducing subsequent damage to the ceramic core compared to the channel without the gasket.

Abstract: An article is disclosed including a manifold, an article wall, a post-impingement cavity and a plurality of post-impingement partitions. The manifold includes an impingement wall defining a plenum and a plurality of impingement apertures. The article wall includes a plurality of external apertures. The post-impingement cavity is disposed between the manifold and the article wall, and is arranged to receive a fluid from the plenum through the plurality of impingement apertures and exhaust the fluid through the plurality of external apertures. The plurality of post-impingement partitions divide the post-impingement cavity into a plurality of sub-cavities, and hermetically separate the plurality of sub-cavities from one another. The impingement wall, article wall and plurality of post-impingement partitions are integrally formed as a single, continuous article. The article may be an airfoil component. A method for forming the article includes forming a single, continuous object by an additive manufacturing technique.

Abstract: A rotor blade includes an airfoil having a blade tip and a tip cavity formed at the blade tip. The tip cavity includes a tip cap that is recessed radially inwardly from the tip and surrounded continuously by pressure and suction side walls of the airfoil. The tip cap further includes an aperture that extends through the tip cap and provides for fluid communication between an internal cavity defined within the airfoil and the tip cavity. An exhaust port provides for fluid communication out the tip cavity through one of the pressure side wall, the suction side wall or the trailing edge. A portion of at least one of the suction side wall and the pressure side wall that defines the tip cavity extends obliquely outwardly from the tip cavity with respect to a radial direction.

Abstract: An additively manufactured (AM) object may include a body including an opening in an exterior surface thereof, the opening having a shape and a first area at the exterior surface of the body. A mask may be positioned over the opening. The mask has the shape of the opening and a second area that is larger than the first area so as to overhang the exterior surface of the body about the opening. A plurality of support ligaments couple to the mask and the exterior surface of the body at a location adjacent to the opening to support a portion of the mask. A coating can be applied to the object, and the mask removed. The final AM object includes a plurality of ligament elements extending from the exterior surface of the body and through the coating adjacent the opening, each ligament element at least partially surrounded by the coating.
