Abstract

A shock strut for an aircraft landing gear is disclosed. The shock strut may include a piston with a piston inner surface and a piston outer surface. A telescoping component may be coaxially aligned and slidably engagable with the piston. At least one of the piston and the telescoping component may be a titanium material. A groove defined by an upper lip and a lower lip may be coupled to at least one of the piston or the telescoping component. A piston ring may be in direct contact with the titanium material. The piston ring may be non-metallic and provide sliding engagement with the titanium material to seal a radial space between the piston and the telescoping component. The piston ring may be at least partially held within the groove, and the groove may limit axial movement of the piston ring.

First claim

What is claimed is:

1. A shock strut comprising:
a piston having a piston inner surface and a piston outer surface;
at least one telescoping component coaxially aligned and slidably engagable with the piston, wherein the at least one telescoping component comprises a titanium material;
a groove defined by an upper lip and a lower lip coupled to at least one of the piston or the at least one telescoping component;
at least one piston ring in direct contact with the titanium m…
