  • Aircraft door and mold for casting the door
    Patent number: 6619372
    Abstract: An aircraft door has an inner framework integrally connected to an outer skin by simultaneously casting the framework and the skin in a mold that holds a single core for each frame element in the form of a rib in a freight door or a beam in a passenger door. The ribs extend circumferentially relative to a longitudinal central axis of the aircraft. The beams extend in parallel to the central aircraft axis. The single core is selected from at least one core type and four core types at the most. The frame elements in the form of ribs or beams have open arches for a considerable weight reduction.
