    Abstract: A process for manufacturing a composite rotor blade includes manufacturing an oversized root region of a root region of a composite rotor blade; fixturing the CMC blade into a machining fixture at a primary Y and Z axis datum located at an attachment fillet radii of the root region; machining V-notches into the oversized root region to form a Y′ and Z′ axis datum of a sacrificial datum system in relation to the primary Y and Z axis datum; applying an oversized coating layer over the attachment fillet radii of the root region; fixturing the CMC blade into a machining fixture at the Y′ and Z′ axis datum of the sacrificial datum system; machining the oversized coating layer to a machined coating layer forming a Y″ and Z″ axis datum with respect to the Y′ and Z′ axis datum of the sacrificial datum system; fixturing the CMC blade into a machining fixture at the Y″ and Z″ axis datum; and machining off the sacrificial datum system removing the V-notches.

    Abstract: Core assemblies and methods for manufacturing components of gas turbine engines include a first core body having a first trunk configured to attach to a first location of a cavity core structure, a first branch extending from the first trunk and configured to form a first portion of a first cooling circuit, the first branch having a first joining surface, and a second core body having a second trunk configured to attach to a second location of a cavity core structure, a first branch of the second core body extending from the second trunk and configured to form a first portion of a second cooling circuit in the component. The first branches of the core bodies joined to form a junction. The junction defines a merger of the first cooling circuit and the second cooling circuit proximate to an exit of the first and second cooling circuits.

    Abstract: A component for a gas turbine engine includes a wall that has an exterior surface and an interior surface spaced from the exterior surface. A cooling circuit extends from the interior surface to the exterior surface. The cooling circuit includes a feed passage that has a first end defining an inlet at the interior surface and a second end spaced from the first end. At least one second passage is in fluid communication with the feed passage. At least one slot passage is in fluid communication with the second end of the feed passage and a cooling slot in the exterior surface.

    Abstract: A hanger for mounting an exhaust liner to an exhaust duct is provided. The hanger includes at least one cable, a cable flange, and a J-shaped flange. The at least one cable extends lengthwise between a first end and a second end. The cable flange has at least one cable aperture configured to receive a portion of the cable. The J-shaped liner flange is configured for attachment to the exhaust liner. The liner flange and cable flange are configured to mate with one another to prevent substantial relative motion between the cable flange and the liner flange in a first direction and in a second direction. The first and second directions are substantially orthogonal to one another.
