Aircraft wing and method for reducing airframe-generated noise

1. Field of the Invention An aircraft wing useful for reducing wing-generated noise comprises:(a) a main element having a leading edge and a trailing edge;(b) at least one slat having a leading edge and a trailing edge, wherein the slat acts cooperatively with the main element to provide lift to the aircraft, and the main edge leading edge and slat trailing edge define a cavity there between; and(c) at least one sound-absorbing structure located on at least a portion of the main element leading edge, at least a portion of the slat trailing edge, in the cavity, or combinations thereof.If located on the main element leading edge or slat-trailing edge, the sound-absorbing structure may be a honeycomb load-bearing structure such as a honeycomb load-bearing structure having a perforated skin or a machine grid structure having an outer skin which is bonded or perforated. If located in the cavity, the sound-absorbing structure may be a flow blocker. The sound-absorbing structure is typically covered during the normal cruise portion of the aircraft's flight, and thus does not adversely impact aerodynamic performance. A method of reducing such wing-generated noise comprises providing the above-described wing for use in an aircraft in flight.
