Abstract
Stator clips may be disposed in the recesses of aircraft brake stator disks to increase the lug strength of the stator disk. The clips may interface with the splines of a torque plate and may comprise ridges that reduce contact between the torque plate barrel and the clip, while maintaining the overall integrity of the clip structure. Furthermore, reduced contact may enable a reduction in drag, improving brake performance.
Claims18
A stator clip, comprising:
- a spline interface, comprising:
- a first face;
- a second face, wherein the first face is opposite the second face, wherein the first face and the second face each comprises a ridge;
- and
- a third face bridging between the first face and the second face, wherein the third face is orthogonal to the first face and the second face;
- a first flange pair, the first flange pair being orthogonal to a reverse side wall of the first face, the first flange pair comprising opposing flanges, each flange defining a lug recess;
- and
- a second flange pair, the second flange pair being orthogonal to a reverse side wall of the second face, the second flange pair comprising opposing flanges, each flange defining a lug recess.

A brake assembly, comprising:
- a torque plate barrel comprising an outer surface disposed around a first reference axis, wherein the outer surface comprises a first spline proceeding about the first reference axis;
- and
- a stator disk assembly mounted on the torque plate barrel, comprising:
- a stator disk comprising an inner perimeter disposed about a first aperture, wherein the inner perimeter comprises a first recess, wherein the inner perimeter comprises a first lug and second lug proximate the first recess, wherein the first lug and the second lug are disposed on either side of the first recess, wherein the torque plate barrel extends into the first aperture of the stator disk;
- and
- a first stator clip disposed within the first recess, wherein:
- the first spline is disposed within a spline interface of the first stator clip, and
- the spline interface comprises:
- a first face;
- a second face, wherein the first face is opposite the second face, wherein the first face and the second face each comprises a ridge, and
- a third face bridging between the first face and the second face, wherein the third face is orthogonal to the first face and the second face.
