초록

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 the...

1. An aircraft wing comprising:(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 element leading edge and slat trailing edge define a cavity therebetween; and (c) at least one sound-absorbing structure located on at least an exterior portion of the main element leading edge, at least an exterior portion of the slat trailing edge, in the cavity, or combinations thereof.
