Abstract: A turbine component assembly is disclosed, including a first component, a second component, and a circumferentially oriented flat spring. The first component is arranged to be disposed adjacent to a hot gas path, and includes a ceramic matrix composite composition. The second component is adjacent to the first component and arranged to be disposed distal from the hot gas path across the first component. The circumferentially oriented flat spring is disposed on and directly contacting the second component and directly contacting and supporting the first component as a compliant contact interface between the first component and the second component. The circumferentially oriented flat spring provides a radial spring compliance between the first component and the second component.

Abstract: Methods for repairing composite cylindrical components are provided. One exemplary method for repairing a cylindrical component defining an axial direction, a radial direction, and a circumferential direction includes removing a damaged region of the cylindrical component. A flange extending from a cylindrical body of the cylindrical component is included in the damaged region. One or more arc segments that extend along the circumferential direction are connected with the existing cylindrical component. At least one of the arc segments includes a prefabricated flange. One or more plies are laid up to connect the arc segments with the existing cylindrical component to repair the damaged region of the cylindrical body and the prefabricated flange formed integrally with one of the arc segments replaces the damaged portion of the flange. Repaired cylindrical components are also provided.

Abstract: A process for producing an internal cavity in a CMC article and mandrels used therewith. The process entails incorporating a mandrel made of a fusible material that is melted and drained during a thermal treatment of a CMC preform to form the CMC article. The mandrel material is preferably non-wetting and non-reactive with any constituents of the CMC preform during the thermal treatment. The mandrel is preferably tin or an alloy of tin.

Abstract: A mask is provided for an additively manufactured part including a plurality of openings in a surface of the part. The mask is made with the part and includes an attachment ligament configured to integrally couple to the part adjacent the plurality of openings. A cover member include a proximal end integrally coupled to the attachment ligament and distal end extending at least partially over the plurality of openings. A detachment member may optionally extend from adjacent the cover member. The attachment ligament is the sole connection to the part. The mask may have an L-shape in cross-section.

Abstract: A mask is provided for an additively manufactured part including a plurality of spaced openings in a surface of the part. The mask is made with the part and includes an attachment ligament configured to integrally couple to the part between the openings in a cantilever fashion. First and second cover members include a proximal ends integrally coupled to the attachment ligament and distal ends extending at least partially over a respective portions of the plurality of openings. A detachment member extends from each of the first and second cover members. The attachment ligament is the sole connection to the part. The mask may have an umbrella shape in cross-section.

Abstract: Methods and features for repairing CMC components are provided. Methods include positioning a plurality of CMC plies at a damaged area of a CMC component and densifying the component and plies. For example, each ply may be a unidirectional ply positioned at the damaged area such that the plurality of plies is oriented in a plurality of directions. As another example, each ply may define a ply direction and comprise a plurality of ceramic fibers substantially extending along the ply direction, and the ply directions of at least two plies may be differently oriented. A repair patch for a CMC component also is provided that comprises a plurality of CMC plies. Fibers forming a first ply extend substantially along a first ply direction and fibers forming a second ply extend substantially along a second ply direction. The first and second plies of the repair patch are oriented in different directions.

Abstract: An anti-rotation shroud dampening pin is disclosed including a shaft, an anti-rotation dampening tip at a first end of the shaft, and a cap at a second end of the shaft. The anti-rotation dampening tip includes a pin non-circular cross-section. A turbine shroud assembly is disclosed, including an inner shroud, an outer shroud, the anti-rotation shroud dampening pin, and a biasing apparatus. The inner shroud includes an anti-rotation depression having a depression non-circular cross-section. The outer shroud includes a channel extending from an aperture adjacent to the inner shroud. The anti-rotation shroud dampening pin is disposed within the channel and in contact with the inner shroud, and extends through the aperture into the anti-rotation depression. The biasing apparatus contacts the cap and provides a biasing force to the inner shroud through the anti-rotation dampening tip. The pin non-circular cross-section mates non-rotatably into the depression non-circular cross-section.

Abstract: A turbine component includes an outer shroud arranged within a turbine and further including opposed extending portions. The component further provides an inner shroud shielding the outer shroud from a gas path within the turbine during operation of the turbine and including opposed arcuate portions extending around and in direct contact with a corresponding extending portion of the outer shroud for supporting the inner shroud from the outer shroud. The component further provides a load path forming region at least partially extending between facing surfaces of each arcuate portion and corresponding extending portion. During operation of the turbine, load path forming regions extend into direct contact between at least a portion of the facing surfaces of each arcuate portion and corresponding extending portion, resulting in formation of a loading arrangement having generally evenly distributed radial load forces at the load path forming regions.
