A one-piece fitting (56) for a stiffened panel (51) comprising a panel body (52) with a plurality of stiffeners (53, 54, 55) arranged thereon, the fitting comprising a fitting body (56) configured to be fastened, in use, to two or more of the stiffeners (53, 54, 55) so as to provide a junction to transfer load between the two or more stiffeners, wherein the fitting body further comprises an integral functional fitting (57) arranged for engagement with a component other than the stiffened panel.

Methods and structures are disclosed. An example method includes: rotating a tubular mandrel about a longitudinal axis of the tubular mandrel; depositing a composite material on an inner surface of the tubular mandrel to form a composite tubular member on the inner surface of the tubular mandrel; inserting and expanding an inner expandable mandrel within the composite tubular member to cause the inner expandable mandrel to press the composite tubular member against the inner surface of the tubular mandrel; curing the composite tubular member; removing the inner expandable mandrel; placing a frame within the composite tubular member; and removing the tubular mandrel so as to obtain the composite tubular member with the frame placed therein.

A joining structure for two door members forming a door member for entrance opening and closing of an aircraft lavatory unit is configured so that a pair of brackets provided on the pair of door members are joined swingably by a bracket joining shaft; and one ends of a pair of covers are joined to the pair of brackets by bracket cover joining shafts, and the other ends of the pair of covers are joined swingably by a cover joining shaft, at a section farther away from the lavatory than the bracket joining shaft.

A hold open rod includes an inner member, an outer member configured to have the inner member slide in and out of the outer member, and a locking mechanism configured to selectively lock the inner member and the outer member with respect to each other. The locking mechanism includes a locking plug configured to move axially along an axis of the inner member and the outer member to a locking position and an unlocking position, a locking dog configured to move radially between a locking position and an unlocking position as a result of a camming action with the locking plug as the locking plug moves axially, and a lock transfer bar operatively connected to the locking plug and configured to move the locking plug to the locking position and the unlocking position when the lock transfer bar is moved.

A water-tight or air-tight accessible compartment has a removable hatch sealed at the edge with elastically conformable opposing seals, with elongate communication elements extending into the compartment between the opposing seals, seals conforming to the topology formed between the compartment edge and the elongate communication elements.

A vehicle having a door slidably mounted on a shell. The vehicle includes at least one assistance device, comprising both a winder carrying a strap and a receptacle, the winder including a brake for braking unwinding of the strap from the winder, one of the winder and receptacle being fastened to the shell and one of the winder and receptacle being fastened to the door, the strap carrying a latchplate suitable for being reversibly attached to the receptacle.

A door assembly for a vehicle. The door assembly includes a door frame, a door panel, a rotating strut, and a linear door guide. The door opens and closes through a combination of rotating and sliding motion, which minimizes the required operational footprint. The strut is mounted on the door panel such that the strut is hidden from view when the door is in an open position.

An aircraft that includes a body that defines a cabin interior and includes an exterior surface and an interior surface, and at least a first panel member having a front and a back. The back includes a set of panel mounting components thereon. The interior surface of the body includes a set of body mounting components thereon. The set of panel mounting components are removably mounted to the set of body mounting components.

A door panel is included in a nacelle assembly for use with a gas turbine engine to block and allow access selectively to the gas turbine engine. The nacelle assembly includes a nacelle wall and the door panel. The nacelle wall is arranged at least partway around the gas turbine engine and formed to define an opening that extends through the nacelle wall. The door panel is located in the opening and movable relative to the nacelle wall.

In an example, a seating system includes a seat comprising a chamber, a wall structure adjacent to the seat and defining a compartment, a door insert configured to move within the compartment between a starting position and a retracted position, wherein in the starting position, the door is adjacent to the seat and blocks access to the compartment, and in the retracted position, the door is retracted into the wall structure and provides access to the compartment, a closed channel extending from the chamber and operably connected to the door, and a piston operably coupled to the seat and positioned within the chamber, wherein when a load is applied to the seat, the piston is compressed, moving the door from the starting position to the retracted position, and when the load is removed, the piston is decompressed, causing the door to move from the retracted position to the starting position.
