发明名称 Skin of an airplane door and method of making door with same
摘要 The skin of an airplane door conforms in use to a surrounding surface contour of an airplane fuselage. The skin is connected with a door frame which has supports arranged in a longitudinal direction of the fuselage and spaced with respect to one another in a circumferential direction. During flight the skin and door frame are exposed to a pressure load direction. To provide the skin of an airplane door with a clearly smaller dimension for the purpose of a light construction thereby avoid displacements on the skin, the skin and door frame are preformed against an in use pressure load direction. During the flight at cruising altitude, the door has essentially no displacements with respect to the surrounding surface contour of the fuselage, and thus essentially no displacements occur which could increase the flow resistance of the skin. Relative to a material, it is possible to thus construct the skin in a smaller thickness than in the case of known doors, but disturbing displacements on the skin are nevertheless essentially avoided while permitting a weight reduction of the door.
