An aircraft decompression assembly, comprising a cabin lining element, an element opening and an air channel adjacent to an element rear face and connected to the opening. A channel outlet, during normal assembly operation, discharges air exiting a cabin region delimited by the element through the opening into a secluded area between the element and an aircraft outer skin. A first decompression opening has a first decompression flap, which during normal operation, closes the first decompression opening and, in the event of a rapid decompression, opens the first decompression opening equalizing a pressure between the cabin region and the secluded area. A second decompression opening in the lining element has a second decompression flap which, during normal operation, closes the second decompression opening and which, in the event of a rapid decompression, opens the second decompression opening equalizing a pressure between the cabin region and the secluded area.

A decompression panel assembly for use in an aircraft includes a body portion comprising a plurality of frame members defining a plurality of openings in the body portion. The decompression panel assembly also includes a baffle member integrally formed with the plurality of frame members such that the baffle member removably obstructs at least one opening of the plurality of openings. The baffle member is configured for at least partial displacement from the at least one opening during a decompression event.

A system for monitoring a pressure change within at least one compartment of an aircraft and operating a pyrotechnic device associated with a door latch, includes a securing mechanism arranged in an aircraft door that includes a pyrotechnic actuator and a latch bolt. The system includes the pyrotechnic actuator configured to move the latch bolt when the pyrotechnic actuator is actuated. The system also includes a pressure sensor configured to provide a pressure signal. The system also includes a controller configured to determine a pressure drop representing a decompression event. The system also includes an output driver configured to generate an output signal to actuate the pyrotechnic actuator when the controller determines the occurrence of a decompression event.

An environmental control system for use in an aircraft includes at least one component positioned along a length of the aircraft and a decompression panel assembly comprising an array of apertures. The array of apertures is based on a location of the decompression panel assembly along the length of the aircraft relative to the at least one component.

A decompression panel assembly for use in an aircraft includes a frame including a first surface and an opposing second surface, wherein the frame defines a grille opening and at least partially defines a flow path opening. The decompression panel assembly also includes a face panel having a first surface retained against the frame second surface such that the face panel at least partially covers the grille opening. A retention mechanism is coupled to the face panel and is configured to retain the face panel against the frame in a closed position.

An auxetic bi-stable structure that comprises an auxetic curved shell movable between a first and a second stable position, and a rigid element. At least part of the surface of the auxetic curved shell is joined to the rigid element such that the curved shell is movable with respect to the rigid element between the first and second stable positions.

A decompression assembly for use in an aircraft comprises a cabin lining element, an opening formed in the element, and an air channel arranged adjacent to a rear face of the element and connected to the opening. The air channel is provided with an air outlet which, during normal operation of the assembly, discharges air exiting a cabin region delimited by the element through the opening into an area located between the element and an aircraft outer skin, a first decompression opening, and a first decompression flap which, during normal operation of the decompression assembly, closes the first decompression opening in the air channel and which, in the event of a rapid decompression, opens the first decompression opening to allow a pressure equalization between the aircraft cabin region and the aircraft area located between the cabin lining element and the aircraft outer skin.

A privacy door assembly for installation in an aircraft relative to a flight deck door of the aircraft includes a door frame having a first post and a second post, where the second post comprises a latch recess. The privacy door assembly also includes a privacy door rotatably coupleable to the first post via a set of hinges, where the privacy door comprises a decompression latch arranged to engage the latch recess when the privacy door is in a closed position within the door frame, and where the decompression latch is configured to disengage from the latch recess in response to a decompression detected on a forward side of the privacy door.

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.
