  • Acoustic attenuator for a turbomachine and methodology for additively manufacturing said acoustic attenuator
    Patent number: 11199202
    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.
