Abstract

A landing gear assembly is also provided. The landing gear assembly may include a thin-skin support member defining a cavity and a cylindrical cavity. A cylinder may extend from the cylindrical cavity with an axle extending from the cylinder. A torsion link may be coupled to the axle and a torsion interface of the thin-skin support member.

First claim

What is claimed is:

1. A method of making a landing gear assembly, comprising:
forging a mounting interface housing comprising a base, and first and second ends that each extend upwardly from the base, wherein the first and second ends comprise first and second holes, respectively, that are aligned with one another and that accommodate coupling to an airframe to allow the landing gear assembly to be moved between a stowed position and a deployed position, wherein an open space extends between the first and second holes;
joining each of first and second sheet metal elements to the mounting interface housing;
joining the first and second sheet metal elements together to define an upper section of a thin-skin support member, wherein the first and second holes of said mounting interface housing are disposed beyond an upper end of the upper section of the thin-skin support member;
forging a mid-body support having a cylinder extending from the mid-body support;
joining each of third and fourth sheet metal elements to the mid-body support;
joining the third and fourth sheet metal elements together to define a lower section of a thin-skin support member; and
joining the upper section of the thin-skin support member to the lower section of the thin-skin support member;
wherein the landing gear assembly comprises a wheel assembly axle that is spaced from the mounting interface housing in a dimension corresponding with a length dimension of the thin-skin support member.

2. The method of claim 1 , wherein the upper section of the thin-skin support member extends from the base of the mounting interface housing and in a direction of the lower section of the thin-skin support member.

3. The method of claim 1 , wherein the first and second holes are spaced from one another along a first axis, and wherein the wheel assembly axle extends along a second axis that is disposed in a different orientation than the first axis.

4. The method of claim 3 , wherein the first axis is orthogonal to the second axis.

5. The method of claim 1 , wherein the mounting interface housing is configured for pivotal connection with the airframe about a pivot axis, and wherein the wheel assembly axle extends along a first axis that is disposed in a different orientation than the pivot axis.

6. The method of claim 5 , wherein the pivot axis is orthogonal to the first axis.

7. The method of claim 1 , wherein the joining the first and second sheet metal elements to the mounting interface housing comprises welding the first and second sheet metal elements to the mounting interface housing.

8. The method of claim 7 , wherein the joining the first and second sheet metal elements together comprises welding the first and second sheet metal elements together.

9. The method of claim 1 , wherein the joining the first and second sheet metal elements together comprises welding the first and second sheet metal elements together.

10. The method of claim 1 , wherein the joining the third and fourth sheet metal elements to the mid-body support comprises welding the third and fourth sheet metal elements to the mid-body support.

11. The method of claim 10 , wherein the joining the third and fourth sheet metal elements together comprises welding the third and fourth sheet metal elements together.

12. The method of claim 11 , wherein the joining the first and second sheet metal elements to the mounting interface housing comprises welding the first and second sheet metal elements to the mounting interface housing.

13. The method of claim 12 , wherein the joining the first and second sheet metal elements together comprises welding the first and second sheet metal elements together.

14. The method of claim 13 , wherein the joining the upper section of the thin-skin support member to the lower section of the thin-skin support member comprises welding the upper section of the thin-skin support member to the lower section of the thin-skin support member.

15. The method of claim 1 , wherein the joining the third and fourth sheet metal elements together comprises welding the third and fourth sheet metal elements together.

16. The method of claim 1 , wherein the joining the upper section of the thin-skin support member to the lower section of the thin-skin support member comprises welding the upper section of the thin-skin support member to the lower section of the thin-skin support member.
