Aircraft Thrust Reverser Corrosion Shield
A corrosion shield for an aircraft thrust reverser includes pivot door skins and side beam skins which cover the pivot doors and side beams of an aircraft thrust reverser. The pivot door skins and side beam skins may be secured using fasteners already included with the aircraft thrust reverser. The pivot door skins and the side beam skins are configured to protect surfaces of the aircraft thrust reverser from exhaust produced by an aircraft engine.
1 . An aircraft thrust reverser corrosion shield, comprising:
a pivot door skin configured for mounting to a pivot door of an aircraft thrust reverser thereby protecting the pivot door from an exhaust of an aircraft engine; and
a side beam skin configured for mounting to a side beam of the aircraft thrust reverser thereby protecting the side beam from the exhaust of the aircraft engine,
wherein the pivot door skin and the side beam skin match up against each other, thereby substantially covering the pivot door and the side beam.
2 . The corrosion shield of claim 1 wherein the pivot door skin and the side beam skin substantially cover an entire exhaust surface of the pivot door and the side beam, respectively.
3 . The corrosion shield of claim 1 comprising a plurality of fasteners, wherein the fasteners are used to fasten the pivot door skin to the pivot door and the side beam skin to the side beam.
4 . The corrosion shield of claim 3 , wherein the fasteners comprise existing fasteners of the pivot door and the side beam.
5 . The corrosion shield of claim 1 wherein the side beam skin and the pivot door skin each include at least one fastener hole, wherein each fastener hole provides access to a fastener.
6 . The corrosion shield of claim 1 wherein the pivot door skin and side beam skin are each fabricated from an Aluminum 6000 alloy.
7 . The corrosion shield of claim 1 wherein the pivot door skin and side beam skin are each fabricated from an Aluminum 5000 alloy.
8 . The corrosion shield of claim 1 wherein the corrosion shield is 0.010 inch to 0.040 inch thick.
9 . The corrosion shield of claim 1 wherein the pivot door skin and the side beam skin each comprise an outer surface configured for directly contacting the pivot door and an inner surface configured for exposure to the exhaust of the aircraft engine.
10 . A corrosion shield for an aircraft thrust reverser, comprising:
a first pivot door skin configured for mounting to an inner surface of a first pivot door of an aircraft thrust reverser;
a second pivot door skin configured for mounting to an inner surface of a second pivot door of the aircraft thrust reverser;
a first side beam skin configured for mounting to an inner surface of a first side beam of the aircraft thrust reverser; and
a second side beam skin configured for mounting to an inner surface of a second side beam of the aircraft thrust reverser,
wherein the first and second pivot door skins and the first and second side beam skins each comprise an exhaust surface configured to face towards a center of the aircraft thrust reverser of an aircraft engine, and
wherein the first side beam skin abuts directly against a first edge of the first pivot door skin and abuts directly against a first edge of the second pivot door skin, and the second side beam skin abuts directly against a second edge of the first pivot door skin and abuts directly against a second edge of the second pivot door skin.
11 . The corrosion shield of claim 10 wherein the first and second pivot door skins cover the pivot doors and the first and second side beam skins cover the side beams, thereby shielding the pivot doors and the side beams, respectively, from aircraft engine exhaust for mitigating corrosion of the pivot doors and the side beams.
12 . The corrosion shield of claim 10 wherein the exhaust surface comprises a corrosion resistant material configured to withstand exposure to aircraft engine exhaust.
13 . The corrosion shield of claim 12 wherein the corrosion resistant material comprises an Aluminum alloy.
14 . The corrosion shield of claim 13 wherein the Aluminum alloy comprises Aluminum alloy 5052.
15 . The corrosion shield of claim 13 wherein the Aluminum alloy comprises Aluminum alloy 6061.
16 . The corrosion shield of claim 10 wherein the first and second side beam skins and the first and second pivot door skins each comprise a curvature that matches their respective pivot doors and side beams of the aircraft thrust reverser.
17 . The corrosion shield of claim 10 wherein the first and second side beam skins and the first and second pivot door skins are each manufactured from an Aluminum alloy, wherein the Aluminum alloy is galvanically compatible between the pivot door skin and the pivot door and is galvanically compatible between the side beam skin and the side beam.
