Abstract
A thin-skin support member is provided. The thin-skin support member may include a semi-circular edge and a flat edge that define a hollow cavity. A cylindrical cavity may be adjacent the hollow cavity and at least partially defined by the semi-circular edge. The cylindrical cavity may be configured to retain a strut assembly. A mounting interface may be coupled to the semi-circular edge and the flat edge. A torsion interface may be disposed adjacent the cylindrical cavity and configured to receive a torsion link. The thin-skin support member may be made using additive manufacturing and thus may have a grain structure grown in the direction of material being added.
Claims5
A method of making a thin-skin support member for a landing gear, comprising:
- selecting a metal;
- and
- forming the thin-skin support member from the metal, wherein the thin-skin support member comprises a first semi-circular edge adjacent to an elongated surface extending to a second semi-circular edge aft of the first semi-circular edge, the thin-skin support member defines a hollow cavity and a cylindrical cavity at its interior, wherein the thin-skin support member has a grain structure grown in the direction of material being added and wherein the elongated surface comprises a rounded surface comprising a radius of curvature larger than a radius of curvature of the first semi-circular edge and the second semi-circular edge, wherein the thin-skin support member further comprises a cutaway section on an open upper end of the thin-skin support member, and wherein an external boundary of the open upper end comprises the cutaway section.
