    FACE SHEET OF ACOUSTIC LINER HAVING STREAMLINED HOLES WITH ELONGATED EDGES

    New search for: BIFULCO ANTHONY R

    A face sheet (110A) of an acoustic liner (110) for a gas turbine engine (20), having: a first surface (120), a second surface (140), and a sheet body (130) extending from the first surface (120) to the second surface (140); a forward end (150), an aft end (160), and the sheet body (130) extending from the forward end (150) to the aft end (160); and a hole formed in the sheet body (130), extending from the first surface (120) to the second surface (140), the hole (170) defining a hole opening (220) at the first surface (120) of the face sheet (110A), and an elongated edge (250) that extends aft at the hole opening (220), wherein the elongated edge (250) defines a flow ramp surface (300) that tapers toward the first surface (120) and is configured to direct flow toward the first surface (120), wherein the flow ramp surface (300) is a streamlining feature.
