According to some embodiments, a door system includes a door attachment device and a receiver. The door attachment device may be coupled to a door, and the receiver may be coupled to a door frame. A receiving surface of the receiver may be configured to at least partially receive the door attachment device along a first axis. The receiving surface may have a non-planar portion curved relative to the first axis such that the receiving surface responds to movement of the door attachment device in a direction parallel to a second axis, the second axis perpendicular to the first axis, by repositioning the door attachment device in a third direction perpendicular to the plane formed by the first axis and the second axis.

The system for controlling the speed of opening a sliding door for an aircraft including a mechanical braking device for the door including a transmission shaft and a centrifugal absorber including a resistance shaft connected to the transmission shaft, and linking means that are designed to be connected to the sliding door and to cooperate with the transmission shaft so that when the sliding door moves in a predetermined direction, the linking means drive the transmission shaft and the centrifugal absorber applies a resistance torque to the transmission shaft in order to control the speed of movement of the door. The system includes a speed reducer connecting the resistance shaft to the transmission shaft so that the speed of rotation of the resistance shaft is greater than that of the transmission shaft when the sliding door moves in the predetermined direction.

A door assembly for mounting on an aircraft includes a rail mounted exteriorly to an outer skin of the aircraft, and a door movably coupled to the rail. The door assembly also includes a motor mountable in an interior of the aircraft, and a shaft extending through a sealed shaft port in the outer skin of the aircraft. The shaft couples the motor to the door, such that the door is movable between a first position and a second position along an outer moldline of the aircraft.

A door assembly for a seat unit provided within a vehicle cabin, in particular an aircraft cabin, the door assembly comprising at least a fixed base structure, a door element movably mounted on the base structure and which is movable between a fully retracted position and at least one deployed position, and a door slide device provided between the base structure and the door element to movably support the door element on the base structure. Further, the door slide device comprises at least a slide carrier bracket fixed to the base structure or the door element, at least one slide unit which is coupled to the slide carrier bracket in a normal operation mode, and at least one separate auxiliary slide arrangement.

A vertical take-off and landing (VTOL) aircraft provides transportation to users of a network system. The network system may include multiple aircraft or other types of vehicles to provide multi-model transportation. An aircraft may include a fuselage, a truss coupled to the fuselage, and multiple distributed electric propellers coupled to the truss. The distributed electric propellers may be positioned on at least two different planes. The fuselage may include a cabin having one or more seats for the passengers arranged in a configuration that has a compact footprint, provides legroom, provides visibility to surroundings of the aircraft, or facilitates convenient ingress or egress of passengers. The aircraft may open a port cabin door and starboard cabin door for simultaneous ingress or egress of passengers.

A door management system on an aircraft includes a fuselage extending along a longitudinal axis in a fore-aft direction parallel to forward flight, an opening in a sidewall of the fuselage, a door mounted on the sidewall to slide in the fore-aft direction between a closed position covering the opening and an open position revealing the opening, a cable attached to the fuselage and the door and a speed governor operatively coupled to the cable to limit a velocity of the door as it moves between the open position and the closed position.

Examples provide a door assembly including a sliding door carrier unit having a disengagement mechanism for utilization within a vehicle cabin. The door assembly includes a sliding door movably mounted to a door support member of a seat unit. The door slides laterally between a fully retracted position and a deployed or partially deployed position. A decoupling latch is engaged to detach the sliding door from one or more slide units on the door support member. An auxiliary slide device includes at least one guide and guide profile to support the door and enable the door to return to the retracted position after the door is decoupled from the slide unit in a backup operational mode. The decoupling mechanism enables a user to return the sliding door to a fully retracted position after a failure of the slide units to operate in a normal operational mode.

One embodiment is an aircraft including a fuselage; a bubble window provided on a side of the fuselage; a door configured to provide ingress into and egress from an interior of the fuselage through an opening in the side of the fuselage aft of the bubble window; a seal between an edge or surface of the door and an edge of the opening; and a deflector assembly connected to the door and configured to deflect from the seal an airflow created by the bubble window.

Systems for latching and locking an aircraft door and associated methods are disclosed. The system comprises a latch and a lock. The latch can be configurable between: a latched configuration where the latch interferes with a lift mechanism for causing lifting of the aircraft door to permit opening of the aircraft door; and an unlatched configuration where the lift mechanism is permitted to cause lifting of the aircraft door. The lock can be configurable between: a locked configuration where a configuration change of the latch from the latched configuration to the unlatched configuration is prevented; and an unlocked configuration where the configuration change of the latch from the latched configuration to the unlatched configuration is permitted.
