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 clamp device includes a clamp portion defining a threaded opening therein. The clamp portion is configured to contact a first side of a beam. The clamp device also includes a threaded fastener configured for insertion into the threaded opening via a hole defined within the decompression panel. The clamp device causes the decompression panel to contact a second side of the beam when the threaded fastener is tightened within the threaded opening.

A fabric barrier for an aircraft compartmental barrier includes a fabric barrier portion and a flexible crosspiece, wherein at least part of one edge of the fabric barrier portion terminates at the flexible crosspiece, wherein the flexible crosspiece is adapted to fit into and be retained within a partially covered groove, wherein the partially covered groove includes a pair of opposing flange portions covering a groove whereby a central longitudinal portion of the groove remains uncovered, wherein the flexible crosspiece is adapted to be released from the partially covered groove by passing between the pair of opposing flange portions during a decompression event. A decompression system for an aircraft compartmental barrier includes said fabric barrier, and a method for isolating two internal volumes within an aircraft using said decompression system.

A water-inflow prevention device is provided by installing a closing lid 6 for blocking a duct 2 of an air pressure regulating valve 1, which regulates air pressure inside a cabin 101. A buoyant body 9 is attached to the disc-shaped closing lid 6 installed to the duct 2 so as to be rotatable around a rotation shaft 7. The buoyant body 9 receives a buoyant force from water when immersed in the water. Since the side of the closing lid 6 in which the buoyant body 9 is attached is thereby floated in the water, the closing lid 6 automatically rotates around the rotation shaft 7 so as to close a ventilation port 2a.

A lining panel having a panel element, a rectangular through hole and a flap is provided. The lining panel has a flap which is rotatable about a hinge integrated into the panel element in order to open and/or close the rectangular through hole. A fuselage element for an aircraft includes such a lining panel.

A passenger aircraft (10) comprising a pressurized cabin, which comprises a top volume (13) and a passenger deck (12), the passenger deck (12) comprising at least one passenger compartment (14) separated from the rest of the passenger volume (16) by walls (15), is characterized in that a burstable wall (22) that extends below the ceiling (19) of the passenger volume and defines the passenger compartment (14) is arranged so as to be adjacent to the side wall (20), the space (23) between the burstable wall (22) and the side wall (20) being open towards the top volume (13) and forming a common pressure chamber therewith.

A pressure relief latch includes a housing, a bolt, a cam, and a spring assembly. The housing includes a door panel, a first lateral panel, and a second lateral panel. The first lateral panel and the second lateral panel extend outward from the door panel. The bolt includes a bolt body and a roller bearing. The bolt body is pivotably mounted to the first lateral panel and the second lateral panel at a bolt pivot axis. The bolt body is pivotable about the bolt pivot axis between a latched position and an unlatched position. The roller bearing is rotatably mounted to the bolt body. The cam is pivotably mounted to the first lateral panel and the second lateral panel. The spring assembly is pivotably mounted to the cam. The spring assembly is configured to bias the cam toward the bolt.

An explosion vent mounted to seal an opening formed on a wall of a closed space comprises a cover being dimensioned to fit on said opening and having a perimeter with an edge adapted to seal the cover against the opening with a sealing element. A spring element is arranged to hold the cover in the opening and the spring element has a direction of spring action. The cover is held by opposite retaining surfaces in the opening and the cover and he retaining surfaces are acting against the spring action of element. The sealing element is positioned against the opening so that the sealing force is directed at least partially crosswise to the direction of the spring action of the spring element.

A decompression lock (10) having a bolt comprises at least two separately formed bolt elements (12, 36), wherein a first bolt element (12) comprises a bolt head (14) and a second bolt element (36) comprises a connecting means, the bolt elements (12, 36) are connected to one another in a rotationally fixed manner such that they can be detached from one another, and a clamp element (16) is provided, which enables the detachable connection. The clamp element (16) is connected securely and non-detachably to one of the bolt elements (12, 36), in particular to the first bolt element (12) and is detachably connected to the other bolt element (12, 36).

Systems, apparatuses and methods provides for technology that moves a locking vent door from an opening position to a locking position, where in the opening position, the locking vent door opens a locking vent, and in the locking position, the locking vent door closes the locking vent. When the locking vent door is in the locking position, the technology prohibits movement of a handle from an engaged position to a disengaged position. When the locking vent door is in the opening position the technology moves the handle from the engaged position to the disengaged position, moves a lock from a locking position to an unlocking position, and moves a pressurization vent door from the pressurization position to the depressurization position based on the lock being moved from the locking position to the unlocking position.
