Abstract: A turbine of a gas turbine engine that includes a stationary shroud ring having inner shroud segments circumferentially stacked about a hot gas path. The inner shroud segments may include a first inner shroud segment that includes: a cooling configuration having cooling channels configured to receive and direct a coolant through an interior of the first inner shroud segment, where each of the cooling channels extends lengthwise between a first end and a second end that includes an outlet formed through an exterior surface of the first inner shroud segment; a circumferential edge; a slot formed in the circumferential edge; and a sealing member positioned within the slot. The outlet of at least one of the cooling channels may be positioned within the slot.

Abstract: A composition of matter includes from about 16 to about 20 wt % chromium, greater than 6 to about 10 wt % aluminum, from about 2 to about 10 wt % iron, less than about 0.04 wt % yttrium, less than about 12 wt % cobalt, less than about 1.0 wt % manganese, less than about 1.0 wt % molybdenum, less than about 1.0 wt % silicon, less than about 0.25 wt % carbon, about 0.03 wt % boron, less than about 1.0 wt % tungsten, less than about 1.0 wt % tantalum, about 0.5 wt % titanium, about 0.5 wt % hafnium, about 0.5 wt % rhenium, about 0.4 wt % lanthanide elements, and the balance being nickel and incidental impurities. This nickel-based superalloy composition may be used in superalloy articles, such as a blade, nozzle, a shroud, a splash plate, a squealer tip of the blade, and a combustor of a gas turbine engine.

Abstract: An air bypass system for a gas turbine engine includes a nozzle for a gas turbine engine. The air bypass system includes the nozzle having an inner band, an outer band, and an airfoil extending between the inner band and the outer band. The airfoil defines an internal passage. A diaphragm includes an inner wall, a first rail, and a second rail, which collectively define a diaphragm cavity. The first rail defines a first rail aperture. A manifold is positioned in the diaphragm cavity. The manifold and the diaphragm collectively define a manifold chamber in fluid communication with the first rail aperture. A tube extends through the internal passage defined by the airfoil and into the diaphragm cavity. The tube is in fluid communication with the manifold chamber. Compressed air flows through the tube into the manifold chamber and exits the chamber through the first rail aperture.

Abstract: A turbine shroud segment including: a target exterior surface and target interior region; and a cooling configuration having first and second channel types. The first channel type includes: an inlet and outlet; a target section extending through the target interior region; lateral ports spaced lengthwise between first and second ends of the target section; and a path within the target interior region offset from the target exterior surface by a minimum offset. The second channel type includes: dead-ends disposed at first and second ends; lateral ports connecting to lateral ports of the first channel type; and a path through the target interior region that is variable between valleys and peaks. The second channel type resides closer to the target exterior surface at the valleys than at the peaks. At each of the valleys, the second channel type resides within the minimum offset.

Abstract: Various embodiments include gas turbine seals and methods of forming such seals. In some cases, a turbine includes: a first arc segment adjacent to a second arc segment, each arc segment including an end surface and radially facing surfaces extending from opposite ends of the end surface; a slot located between the end surfaces of the first arc segment and the second arc segment; and a first seal disposed in the slot, the first seal contacting the first arc segment at the end surface and extending over the radially facing surfaces of the first arc segment, the first seal including: a shim contacting the first arc segment; a laminate material over the shim and covering the shim; and a conforming material coupling the laminate material to the shim.

Abstract: A component includes a substrate configured to receive tensile stress in a first direction. The substrate includes a recess defined therein on a surface. The recess includes a first portion having a first width defined in a second direction. The recess also includes a second portion having a second width defined substantially parallel to the second direction, and a third portion between the first and second portions along the first direction. The third portion having a third width defined substantially parallel to the second direction such that each of the first width and the second width is different than the third width. The component further includes an insert coupled to the substrate. A perimeter of the insert is sized substantially identically to a perimeter of the recess such that the insert is received within the recess in a clearance fit.
