Aircraft landing gear

1. An aircraft landing gear including:

a first component;

a second component;

a coupling region movably coupling the first component to the second component, the coupling region defining one or more side walls extending between the first component and the second component, the coupling region comprising a noise-inducing region; and

a cover arranged to fully enclose the noise-inducing region in an adjacent manner to inhibit an airflow negotiating the noise-inducing region when the landing gear is in use, the cover comprising a flexible material arranged to permit the movement of the first component relative to the second component, the cover being in contact with the coupling region all of the way around the side walls and all of the way along the side walls so as to extend all of the way around the coupling region and all of the way along the coupling region;

wherein the cover encloses no more than one pin joint.

2. The aircraft landing gear according to claim 1 , wherein the cover is arranged to prevent the airflow passing through it.

3. The aircraft landing gear according to claim 1 , wherein the cover includes a coupling portion arranged for attachment to one or more components of the landing gear to maintain the cover in position.

4. The aircraft landing gear according to claim 3 , wherein at least half of the coupling portion is adjacent to the one or more components.

5. The aircraft landing gear according to claim 1 , wherein the cover comprises at least part of a sleeve.

6. The aircraft landing gear according to claim 1 , wherein the cover comprises at least part of elongate strip of material wound around the noise-inducing region.

7. The aircraft landing gear according to claim 1 , wherein the cover is arranged to resiliently grip the one or more side walls.

8. The aircraft landing gear according to claim 1 , wherein the noise-inducing region of the coupling region has one or more outer peripheral surfaces and one or more inwardly extending surfaces or cavities, and the cover is adjacent or in contact with the outer peripheral surfaces of the coupling region so as to provide a low profile cover that conforms to the coupling region.

9. A method of reducing noise created by an aircraft landing gear in use, the method comprising the steps of:

providing an aircraft landing gear including a noise-inducing region wherein the landing gear includes a first component movably coupled to a second component via a coupling region, the coupling region comprising the noise-inducing region; and

fully enclosing and contacting a periphery of the noise-inducing region all of the way around and all of the way along the noise-inducing region in an adjacent manner with a cover to inhibit an airflow negotiating the noise-inducing region when the landing gear is in use, wherein the cover comprises a flexible material arranged to permit the movement of the first component relative to the second component, and wherein the cover encloses no more than one pin joint.

10. The method according to claim 9 , wherein the step of fully enclosing comprises sliding a sleeve over the noise-inducing region to form the cover.

11. The method according to claim 9 , wherein the step of fully enclosing comprises winding a wrap around the noise-inducing region to form the cover.

12. An aircraft landing gear including:

a first component;

a second component;

a joint movably coupling the first component to the second component, the joint comprising a noise-inducing region; and

a cover comprising a cover portion arranged to fully enclose the noise-inducing region in an adjacent manner to inhibit an airflow negotiating the noise-inducing region when the landing gear is in use;

wherein:

the cover portion comprises a flexible material arranged to permit the movement of the first component relative to the second component;

the cover is in contact with one or more outer surfaces of the joint all of the way around and all of the way along the joint; and

the cover portion encloses no more than one pin joint.

13. An aircraft landing gear including:

a first component;

a second component;

a pin joint movably coupling the first component to the second component, the pin joint comprising a noise-inducing region; and

a cover arranged to fully enclose the noise-inducing region in an adjacent manner to inhibit an airflow negotiating the noise-inducing region when the landing gear is in use;

wherein:

the cover comprises a flexible material arranged to permit the movement of the first component relative to the second component; and

wherein the cover encloses no more than one pin joint.
