Abstract
A shock absorber includes a first end configured to be mechanically fastened to a first component, a second end configured to be mechanically fastened to a second component, a main body, a main shaft, and a primary piston. The primary piston configured to move within the main body and further configured to provide a first damping force by movement of a fluid through the primary piston while the main shaft moves a first distance. The shock absorber also includes a deformable solid material arranged in the main body. The primary piston configured to further move within the main body and further configured to provide a second damping force by deforming the deformable solid material after the main shaft moves the first distance.

A shock absorber, comprising:
- a first end configured to be mechanically fastened to a first component;
- a second end configured to be mechanically fastened to a second component;
- a main body that is attached to the first end;
- a main shaft that is attached to the second end;
- a primary piston configured to be received in the main body;
- the primary piston being attached to the main shaft and the primary piston being further configured to be movable with the main shaft;
- the primary piston configured to move within the main body and further configured to provide a first damping force by movement of a fluid through an orifice in the primary piston while the main shaft moves a first distance;
- a deformable solid material arranged in the main body;
- and
- the primary piston configured to further move within the main body and further configured to provide a second damping force by deforming the deformable solid material after the main shaft moves the first distance,
- wherein one of the first component and the second component comprises a fixed structure;
- wherein another one of the first component and the second component comprises a movable structure;
- wherein the movable structure is an aircraft cockpit door, pivotally mounted within a partition separating an aircraft cockpit from an aircraft passenger cabin;
- wherein the primary piston is configured to move within the main body and further configured to provide the first damping force to reduce velocity during movement at a first rate of speed of one of the first component and the second component;
