Abstract: A turbine having a stationary shroud ring formed about rotor blades. The stationary shroud ring may include an inner shroud segment. The inner shroud segment may include a cooling configuration that includes a crossflow channel. The crossflow channel may extend lengthwise between an upstream end and a downstream end, and, therebetween, include a junction point that divides the crossflow channel lengthwise into upstream and downstream sections, with the upstream section extending between the upstream end and the junction point, and the downstream section extending between the junction point and the downstream end. The crossflow channel may have a cross-sectional flow area that varies lengthwise such that a cross-sectional flow area of the upstream section decreases between the upstream end and the junction point, and a cross-sectional flow area of the downstream section increases between the junction point and the downstream end.

Abstract: A hollowed body component made by additive manufacturing is disclosed. The hollow body has a longitudinal extent, an exterior surface and an interior surface, the interior surface having a first side and an opposing, second side. A first set of curved supports are curved along lengths thereof and extend between the first side and the opposing, second side to support the hollow body at least during the additive manufacturing thereof. Some embodiments include cooling passages open to the interior surface. Here, the curved supports extend between opposing pairs of passage-free spaces on the interior surface to support the hollow body at least during the additive manufacturing thereof. In one example, the component is an impingement insert for a hot gas path component.

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: Vibration systems and systems including vibration systems for filling incomplete components with slurry material are disclosed. The vibration systems may include a vibration platform, and a component retention plate releasably coupled to the vibration platform. The component retention plate may include a plurality of component holders positioned on the component retention plate. Each of the plurality of component holders may receive a distinct, incomplete component in a predetermined orientation. The vibration systems may also include a motor operatively coupled to the vibration platform to vibrate the vibration platform at a predetermined frequency. The predetermined frequency may be based on characteristic(s) of each of the incomplete components.

Abstract: Turbine shrouds for turbine systems are disclosed. The turbine shrouds may include a unitary body including a forward and aft end, an outer surface facing a cooling chamber formed between the unitary body and a turbine casing of the turbine system, and an inner surface facing a hot gas flow path. The shrouds may also include a first cooling passage extending within the unitary body, and a plurality of impingement openings formed through the outer surface of the unitary body to fluidly couple the first cooling passage to the cooling chamber. Additionally, the shrouds may include a second cooling passage and/or a third cooling passage. The second cooling passage may extend adjacent the forward end and may be in fluid communication with the first cooling passage. The third cooling passage may extend adjacent the aft end, and may be in fluid communication with the first cooling passage.

Abstract: An injection mold system for injecting slurry into an internal portion of an injection mold component core is disclosed. The system may include a fill clip for injecting slurry into an internal portion of an injection mold component core including a fill member for injecting slurry into the internal portion of the injection mold component core, and a latch member for removably coupling the fill member with the injection mold component core. The system may also include a fill reservoir for collecting excess slurry from the internal portion of the injection mold component core. The fill reservoir may also redistribute the excess slurry back into the internal portion of the injection mold component core.
