    Abstract: An acoustic attenuator for a turbomachine and methodology for additively manufacturing the acoustic attenuator are provided. The acoustic attenuator includes an annular body (202) having an outer surface (204) and an inner surface (206). The inner surface of the annular body may define a bore (208) extending along a longitudinal axis (209) of the acoustic attenuator between a first end and a second end of the acoustic attenuator. The annular body may be formed by a plurality of axially-successive cross-sectional layers (e.g., 632, 634, 636) unitized between the first end and the second end of the acoustic attenuator. The plurality of axially-successive cross-sectional layers may be transversely disposed relative to the longitudinal axis of the acoustic attenuator. At least some axially-successive cross-sectional layers of the plurality of axially-successive cross-sectional layers (e.g., 632, 634, 636) defining a pocket (214) disposed between the outer surface and the inner surface of the annular body. At least a segment of a periphery of the pocket comprises two sides (1452, 1454) arranged to join at a common end point to form an apex (1460) of the pocket.

    Abstract: A method for protecting a turbomachine from corrosion may include creating a first sand mold in a drag of a casting flask, coupling a cope of the casting flask to the drag, removing the runner pin and the at least one riser pin from the cope to expose a runner and at least one riser, respectively, and pouring a molten first material in the runner to cast a first component of the turbomachine. The method may further include removing the first sand mold, creating a second sand mold utilizing the first component in the drag, coupling the cope to the drag, removing the runner pin and the at least one riser pin from the cope to expose a runner and at least one riser, respectively, and pouring a molten second material in the runner to cast a second component of the turbomachine integral with the first component.

    Abstract: An impeller may include a hub section, a plurality of blades, and a shroud. The hub section may be mounted on a rotatable shaft. The hub section may define a central opening for the rotatable shaft to extend therethrough and may define a plurality of holes disposed in a circular manner about the central opening. The plurality of blades may be connected to or integral with the hub section. The shroud may be connected to or integral with the hub section and the plurality of blades. The plurality of holes may be either through holes or partially drilled holes. A bottom of some or all of the partially drilled holes may be flat, conical, or rounded. Some or all of the partially drilled holes may have one or more bleed holes that may permit quenching material to flow therethrough and prevent the quenching material from stagnating therein.
