Abstract
An aircraft assembly may comprise an interior aircraft monument, an aircraft structure, and a load absorbing tie rod coupled to the interior aircraft monument and the aircraft structure. The load absorbing tie rod may include an outer cylinder coupled to the aircraft structure, a piston located at least partially within the outer cylinder and coupled to the interior aircraft monument, and a compressed gas located in a volume defined by the piston and the outer cylinder.
Claims20
A load absorbing tie rod, comprising:
- an outer cylinder;
- a piston located at least partially within the outer cylinder;
- and
- a compressed gas located in a volume defined by the piston and the outer cylinder, wherein the compressed gas is configured to allow translation of the piston toward a first end surface of the outer cylinder in response to a load greater than a first load threshold being applied to the piston and to prevent translation of the piston toward the first end surface of the piston in response to loads less than the first load threshold being applied to the piston.

5 more elements
A method, comprising:
- attaching a piston of a load absorbing tie rod to an interior cabin monument;
- and
- attaching an outer cylinder of the load absorbing tie rod to an aircraft structure, wherein a compressed gas contained in the outer cylinder is configured to allow translation of the piston toward a first end surface of the outer cylinder in response to a load greater than or equal to a first load threshold being applied to the piston and to prevent translation of the piston toward the first end surface of the piston in response to loads less than the first load threshold.
