Methods are provided by which a treatment fluid (e.g., a liquid corrosion inhibitor) may be applied onto the interior surfaces of an aircraft fuselage. The methods include (a) deploying an automated guided vehicle (AGV) comprising a carriage assembly and a robotic spray system carried by the carriage assembly within the interior of the fuselage, (b) closing the cabin door opening of the fuselage with the AGV positioned therewithin, and (c) operating the AGV so as to move within the fuselage along a longitudinal axis thereof to spray the treatment fluid onto the surfaces thereof.

An aircraft of flying wing or blended wing body type comprising, for access to a pressurized housing, a non-pressurized door in the trailing edge of the aircraft and a pressurized door on the pressurized housing. The distance between the center of the pressurized door and a plane of symmetry of the aircraft is less than or equal to the distance between the center of the non-pressurized door and the plane of symmetry, and the pressurized door is located on a wall other than a rear wall of the pressurized housing or upstream of a rear extremum point of the housing in the absence of any such rear wall.

Systems and methods include providing an aircraft with a fuselage, an airframe that provides structural rigidity to the fuselage, and at least one door that allows access to an interior of the fuselage through an opening in the fuselage. The aircraft includes an overlapping, tongue and groove door interface formed between a frame of the door and a portion of the airframe that at least partially borders the opening in the fuselage. At least a portion of the airframe includes a concavity. At least a portion of the door frame includes a complementary shaped profile to the concavity of the airframe. The complementary profile of the door frame and the concavity of the airframe form a seal between the door frame and the airframe when the complementary portion is at least partially received within the concavity by selectively rotating the door to its closed position.

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.

An aircraft door including a door leaf, a door frame, a support arm assembly, and first and second connecting elements. The first connecting element connects the support arm assembly with the door leaf and includes a first adjustment unit that is adapted for adjusting the position of the door leaf relative to the door frame along a first axis (x-axis). The second connecting element connects the support arm assembly with the door frame and includes a second adjustment unit that is adapted for adjusting the position of the door leaf relative to the door frame along a second axis (z-axis) that is perpendicular to the first axis (x-axis).

A vehicle door unit comprises a rotating lever supported rotatably about a first shaft at a first end, a door mounting coupled rotatably about a second shaft to a second end of the rotating lever, a door attached to the door mounting and being configured to cover an opening in a vehicle and to close off a vehicle interior, and a drive unit configured to rotate the rotating lever about the first shaft between a closed position and an open position. The rotating lever is configured to move the second shaft, on a movement from the closed position to the open position, on a circular path, due to which the door mounting is first moved into the vehicle interior and, on further rotation of the rotating lever, out of the vehicle interior.

A door assembly for an aircraft includes a door, a door hinge, and a support assembly rotatably mounting the door hinge to the door. The support assembly includes a forearm and at least one link. The forearm is rotatably mounted to the door hinge along a first rotational axis. The forearm extends along the first rotational axis between and to an upper end and a lower end. The at least one link extends between and to an inner end and an outer end. The at least one link is rotatably mounted to the forearm at the inner end. The at least one link is rotatable relative to the forearm about a second rotational axis. The at least one link is rotatably mounted to the door at the outer end. The at least one link is rotatable about the second rotational axis between and to a lowered position of the door and a raised position of the door.

The invention relates to an aircraft door having a support arm (6) connected to a support forearm (9) by a first pivot connection (7) about a first pivot axis (8), the support forearm (9) being connected to the leaf (5) by a second pivot connection (10) about a second pivot axis (11) parallel to the first pivot axis (8). The support arm (6) is connected to the door frame (4) by two hinges (13, 14) each having a pivot (26, 27) for rotating the support arm (6) about a third pivot axis (12) which is parallel to the first pivot axis (8) and to the second pivot axis (11), this pivot (26, 27) being connected to the door frame (4) by an attachment (22, 23) that is translatably adjustable in two directions (35, 37, 43, 47) orthogonal to one another and orthogonal to the third pivot axis (12).

An aircraft door having: a first handling arm and a first forearm; a second handling arm and a second forearm; a holding device movable between: an immobilising position in which the first forearm and the second forearm are immobilised relative to the door panel; and a released position in which the first forearm and the second forearm are free to pivot relative to the door panel in at least one direction of rotation.

An access system for a vehicle includes a door moveably coupled to a portion of a fuselage. The door is configured to be moved between an open position in which an opening of an internal chamber is opened, and a closed position in which the opening of the internal chamber is closed. One or more actuators are secured to the door. The one or more actuators are configured to move the door between the open position and the closed position.
