Patent number: 11623727Abstract: An aircraft-fuselage structure with an external skin and reinforcement structure, supporting the external skin and includes transverse reinforcement elements and longitudinal reinforcement elements. A door opening is in the external skin, between two transverse reinforcement elements and between two longitudinal reinforcement elements, and a door arrangement is installed therein, the door arrangement having a door frame fastened in the door opening and a door panel fastened on the door frame. The door frame and/or the door panel have/has an outer surface directed towards the surroundings and having a curvature differing from curvature of the external skin adjacent to the door opening, and an adapter arrangement is on the outer surface of the door frame and/or of the door panel and, on a side directed towards the surroundings, has at least one surface element which steadily continues the curvature of the external skin adjacent to the door opening.Type: GrantFiled: January 23, 2020Date of Patent: April 11, 2023Assignee: Airbus Operations GmbHInventor: Günter Pahl

Patent number: 8459592Abstract: The present invention relates to a fuselage nose door for sealing an opening in the hull of an aircraft. In order to make loading and unloading as efficient as possible, a door shell is proposed that is movably held between a closed setting and an open setting by a bearing device, wherein the door shell can be pivoted and shifted in relation to the bearing device. The invention also relates to an aircraft with such fuselage nose door. In addition, the invention also relates to a method for opening and closing an opening in the hull of an aircraft with a fuselage nose door, which has a door shell that is movably held by a bearing device between the closed setting and open setting, wherein the door shell is pivoted and shifted in relation to the bearing device in the opening and closing process.Type: GrantFiled: March 31, 2010Date of Patent: June 11, 2013Assignee: Airbus Operations GmbHInventor: Günter Pahl

Patent number: 8322656Abstract: A wing-fuselage section of an aircraft, which wing-fuselage section comprises a wing root at which the wing of the aircraft is connected to the fuselage, a fuselage region with fuselage frame elements that extent across the longitudinal direction of the aircraft, and a wing region with spars that extend in the direction of the wingspan. According to the invention, the spars of the wing region and the fuselage frame elements of the fuselage region form part of an integral assembly that extends at least over a middle part of the wing and the fuselage region, including the wing roots.Type: GrantFiled: April 21, 2008Date of Patent: December 4, 2012Assignee: Airbus Operations GmbHInventor: Günter Pahl

Patent number: 8240607Abstract: An aircraft fuselage section includes a first interior tube as well as a second interior tube that are produced in an upstream production step, which interior tubes are subsequently enclosed by an exterior tube. For spacing and in order to provide more stability to the tubes the interior tubes are enclosed by straps that are arranged between the interior tubes and the exterior tube.Type: GrantFiled: June 28, 2006Date of Patent: August 14, 2012Assignee: Airbus Operations GmbHInventor: Günter Pahl

Patent number: 7290736Abstract: The present invention concerns a sliding door, which, for example, can be guided on three rollers on the door side in rails on the aircraft structure. Locking of such a cargo door occurs by movement of the cargo door parallel to the aircraft X-axis with the locking pins in corresponding sleeves situated on the aircraft structure. In order to guarantee this, the door opening must be larger than the door itself. The gap produced by this is now closed by means of a locking element that clamps the door. This permits a light structure of the cargo door and therefore a weight saving.Type: GrantFiled: December 21, 2004Date of Patent: November 6, 2007Assignee: Airbus Deutschland GmbHInventor: Guenter Pahl
