ABSTRACT:
An aircraft in which the fuselage and wings are configured in a blended wing design has a door opening in the fuselage adjacent the wing and a door assembly for closing the door opening. The door assembly includes a door having an exterior panel that conforms to the shape of the aircraft at the location of the door opening when the door is closed and having an interior structure configured in a series of steps. The door is movable between a closed position in which an upper edge of the door panel is adjacent an upper edge of the door opening and an open position in which the door panel lies substantially within the wing and in which the upper edge of the door panel is adjacent an upper surface of the wing and spaced from the fuselage. When the door is in the open position, the steps form a stairway leading from the fuselage up and out of the aircraft to the upper surface of the wing. Preferably, the door assembly also includes a movable wing panel which is slaved to the door such that, as the door is moved from the closed to the open position, the wing panel moves to uncover an opening in the wing upper surface through which the door passes to reach its open position.
