    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.

    Abstract: Aspects of the embodiments set forth a sacrificial plug system including a component having a surface and at least one cooling hole in the surface; a sacrificial plug integrally formed with the component and integrally formed in the at least one cooling hole, where the sacrificial plug includes a top portion; a cover portion; and a bottom portion, the bottom portion integrally formed, engaged to, and connected to at least one cooling hole. The sacrificial plug system also includes at least one connective member integrally formed with the bottom portion of the sacrificial plug and integral with an inner wall of each respective at least one cooling hole; each at least one connective member being severable from the respective inner wall when a force is applied to the top portion, thus permitting the sacrificial plug to be removed from the at least one respective cooling hole.

    Abstract: A turbine rotor blade is additively manufactured and includes an airfoil body with a radially extending chamber for receiving a coolant flow. A platform extends laterally outward relative to the airfoil body and terminates at at least one slash face. A cooling circuit is within the platform and is in fluid communication with a source of the coolant flow. Cooling passage(s) are in the platform and in fluid communication with the cooling circuit. The cooling passage(s) extend in a non-linear configuration from the cooling circuit to exit through the at least one slash face of the platform, providing improved cooling compared to linear cooling passages.

    Abstract: Turbine shrouds including shot peen screens integrally formed therein. The shroud may include a unitary body having a support portion coupled directly to a turbine casing of the turbine system, an intermediate portion integral with and extending away from the support portion, and a seal portion integral with the intermediate portion, opposite the support portion. The unitary body may also include an inlet opening(s) formed in the support portion, a plenum(s) in fluid communication with the inlet opening(s), and a cooling passage extending through the seal portion and in fluid communication with the plenum(s). Additionally, the unitary body may include a shot peen screen(s) positioned within the plenum(s) and extending within the intermediate portion. The shot peen screen(s) may include a plurality of voids formed therethrough and may prevents shot from passing through the shot peen screen(s) when performing a shot peening process on the unitary body.

    Abstract: A method for constructing a variable nozzle assembly within a turbine engine that includes: constructing a variable nozzle sub-assembly; attaching the variable nozzle sub-assembly to a casing; and linking segments of a segmented shaft via an opening. Constructing the variable nozzle sub-assembly may include: attaching a downstream inner platform to a upstream inner platform; inserting an outer stem of a first segment through an outer stem opening formed through the downstream outer platform; connecting the first segment to the downstream outer platform by loading a first bearing about a protruding spherical shaped section of the outer stem; inserting the inner stem through an opening formed through the downstream inner platform while aligning sidewalls of the downstream and upstream outer platforms; mechanically securing the aligned sidewalls; and connecting the first segment to the downstream inner platform by loading a second bearing about a protruding spherical shaped section of the inner stem.

    Abstract: A turbine airfoil includes a leading edge, a trailing edge, a pressure side wall extending between the leading edge and the trailing edge, a suction side wall extending between the leading edge and the trailing edge, a cooling air supply cavity disposed within the turbine airfoil, and a near wall cooling cavity disposed within the turbine airfoil and fluidly coupled to the cooling air supply cavity to receive cooling air. In addition, the near wall cooling cavity partially extends along the suction side wall from adjacent the leading edge to a location more proximal the trailing edge. Moreover, the near wall cooling cavity provides near wall cooling to a high heat load region along the suction side wall.
