Aircraft door (1) including an opening (4), a frame (3), a hinge structure (5) and a circular translation guide device designed to maintain the orientation of the opening (4) during the opening or closing thereof. The hinge structure (5) is connected to the opening (4) by a lifting arm (8) allowing a lifting movement of the opening (4) relative to the hinge structure (5). The circular translation guide device includes a single link (11) connected to the frame (3) by one of the ends thereof and by the other of the ends thereof to a lever (13) which is attached to the hinge structure (5).

Systems and methods include providing an aircraft with a fuselage having a sliding door system disposed on at least one side of the fuselage. The sliding door system includes a forward sliding door having an upper slide rail and a lower slide rail, a rearward sliding door having an upper slide rail and a lower slide rail, an upper rail coupled to each of the upper slide rail of the forward sliding door and the upper slide rail of the rearward sliding door, a lower rail coupled to each of the lower slide rail of the forward sliding door and the lower slide rail of the rearward sliding door, and a plurality of actuators coupled to each of the upper rail and the lower rail and configured to displace and retract the forward sliding door and the rearward sliding door linearly with respect to the fuselage.

A system for an automated cabin-divider door for an aircraft includes a door, a motor for moving the door to an open position, a limit switch configured to detect when the door is in a fully open position and to stop the motor, and electronics coupling the motor and the limit switch to an avionics system. The avionics system determines when the door is to be opened and provides a signal to the motor for moving the door to the fully open position. A method for automatically opening the cabin-divider door includes determining whether the aircraft is on the ground or in flight, determining whether the aircraft is taxiing, and determining whether the aircraft is in a final phase of approach. When the aircraft is taxiing or in the final phase of approach, the method includes sending a command signal to the motor for opening the cabin-divider door.

The invention relates to an opening system (10) for an auxiliary door (20) of an airplane in a fuselage (30), the door and the fuselage having skins in the extension of one another. In one exemplary embodiment, the system (10) includes a framing lintel (11) integrated into the fuselage, an upper beam (2S) of the door structure arranged opposite the lintel (11), and a set of three lever links (4A, 4B, 4C). Each link is connected, on the one hand, to the lintel (11) by a lever articulation (5a, 6a) fixed relative to the fuselage (30) and, on the other hand, to the upper beam (2S) by a lever articulation (5b, 6b) mobile with the door (20), the articulations (5a, 5b; 6a, 6b) being connected respectively to the lintel (11) and to the upper beam (2S) by fittings (41, 43; 42, 44). The set of links includes two types of link mounted alternately, in which the mobile articulation (5b, 6b) remains positioned respectively close to the fuselage skin (30) and further from this skin (30), the articulations (5a, 5b; 6a, 6b) of two adjacent levers (4A, 4B; 4B, 4C) forming an evolving quadrilateral.

An aircraft-fuselage structure with an external skin and reinforcement structure, supporting the external skin and includes transverse reinforcement elements and longitudinal reinforcement elements. A door opening is in the external skin, between two transverse reinforcement elements and between two longitudinal reinforcement elements, and a door arrangement is installed therein, the door arrangement having a door frame fastened in the door opening and a door panel fastened on the door frame. The door frame and/or the door panel have/has an outer surface directed towards the surroundings and having a curvature differing from curvature of the external skin adjacent to the door opening, and an adapter arrangement is on the outer surface of the door frame and/or of the door panel and, on a side directed towards the surroundings, has at least one surface element which steadily continues the curvature of the external skin adjacent to the door opening.

An assembly is provided for an aircraft. This aircraft assembly includes a fuselage and a second system. The fuselage includes a wall and a hatch configured to close an opening in the wall. The sensor system includes an optical fiber, a transmitter and a receiver. The optical fiber is arranged at an interface between the hatch and the wall. The transmitter is configured to transmit first electromagnetic radiation into the optical fiber. The receiver is configured to detect second electromagnetic radiation received from the optical fiber to provide receiver data. The sensor system is configured to detect fluid leakage across the interface between the hatch and the wall based on the receiver data.

A frame member, a monument for a vehicle, and a vehicle are provided. The frame member includes an extrusion that has a spar with first and second opposing surfaces and first and second opposing ends. The spar includes a first retention lip extending from the first planar surface along the first end at an acute angle relative to the first planar surface. The spar includes a rub strip protrusion extending from the first planar surface between the first and second ends. The rub strip protrusion includes a third end and a second retention lip extending from a third surface facing the first retention lip. The second retention lip and the third surface form an acute angle. The extrusion also includes at least two panel protrusions extending from the second planar surface of the spar. A rub strip can include retention tabs with outward-facing notches that engage the first and second retention lips.

An aircraft includes a clearance between an opening and a door. The clearance communicates with a cavity and is oriented in a direction intersecting a flow direction of an air flow to the outside of the aircraft in flight. The aircraft further includes an upstream edge and an upstream outer surface situated in front of the clearance joined by a sharp edge with a bend radius of less than or equal to 1 mm, in order to limit the incidence of aerodynamic noise.

Actuation assemblies for emergency devices (e.g., inflatable life rafts carried on-board an aircraft) are provided with enhanced (preferably multiple) levels of security to preclude inadvertent unlatching and/or deployment but also allow access to an on-board emergency device removably positioned within a device bay of the vehicle which is normally covered by an access panel. The actuation assembly may be provided with a rotatable actuation shaft, a manually operated actuation lever fixed to the actuation shaft so as to rotate the actuation shaft in response to movement of the actuation lever between stowed and deployed conditions thereof, and a safety locking system operably connected to the rotatable shaft and having a locked condition which prevents operation of the actuation lever to thereby maintain the actuation assembly in a safe mode during normal vehicle operation, and an armed mode which allows the actuation lever to be moved into the deployed condition thereof.

A door frame for an aircraft includes first and second beams, each having a first end and a second end. The second beam is substantially parallel to the first beam. A third beam extends from the first end of the first beam to the first end of the second beam. The third beam is substantially perpendicular to the first beam and the second beam. A first flange extends from the second end of the first beam in a direction that is away from the second beam. The first flange is substantially perpendicular to the first beam.
