Abstract
A thrust reverser arrangement may comprise an inner fixed structure (IFS), a track beam, a translating sleeve slideably mounted to the track beam, a bypass duct defined between the IFS and the translating sleeve, and an acoustic treated fairing coupled to the translating sleeve, wherein the acoustic treated fairing is configured to attenuate noise generated during operation of a gas turbine engine.
Claims17
A thrust reverser arrangement comprising:
- an inner fixed structure (IFS);
- a track beam;
- a translating sleeve including a primary slider coupled to an inner panel of the translating sleeve, the primary slider being slidably mounted in a slot in the track beam;
- a bypass duct defined between the IFS and the translating sleeve;
- and
- an acoustic treated fairing coupled to the inner panel of the translating sleeve, wherein the acoustic treated fairing is disposed along a longitudinal edge portion of the inner panel, and wherein the acoustic treated fairing extends both radially inward from the inner panel and circumferentially toward the track beam and in the direction of a longitudinal edge of the translating sleeve in overlying relation to the inner panel so as to form a gap between the inner panel and the acoustic treated fairing, and also over the primary slider to enclose, at least partially, the primary slider, wherein the primary slider is disposed at least partially within the gap;
- wherein the acoustic treated fairing is configured to attenuate noise generated during operation of a gas turbine engine;
- and
- the acoustic treated fairing is configured to move together with the translating sleeve with respect to the track beam.
