Patent number: 6958105Abstract: A forming jig includes a grid pattern of support walls arranged on a support base and having upper free ends located along an imaginary curved surface, and modular sectional profile members arranged on the walls to enclose a vacuum chamber within the jig. Grooves, channels and air passages between neighboring profile members communicate into the vacuum chamber. The outer surface of the profile members matches the intended inner surface of a structural component to be fabricated using the jig. In the fabrication process, a film is applied to the outer surface to pre-establish a vacuum, the film is removed while simultaneously a vacuum skin is applied, stringer members are set into the grooves, fiber skin layers are laid up, a sealant is applied around the perimeter, a structural shell is vacuumed onto the skin layers, and then this preformed component is removed from the jig, injected with resin unless the skin layers were pre-impregnated with resin, and cured.Type: GrantFiled: August 8, 2003Date of Patent: October 25, 2005Assignee: Airbus Deutschland GmbHInventors: Axel Siegfried Herrmann, Arno Pabsch

Publication number: 20040173605Abstract: A microwave device for de-icing and keeping areas of hollow body structures free from ice keeps atmospherically exposed leading edges and adjacent areas free of ice by means of a coolant circuit. The surface segments between the adjacent areas are kept free from ice as a result of the effects of a microwave device on the wall of the surface segments and the heating that occurs by the exposure to microwave radiation. A series of consecutive microwave-tight chambers is disposed behind the wall of the exposed area. A microwave source supplies microwaves to the chambers with the aid of a decoupling structure disposed therein, resulting in high/multimode excitation. The waste heat of the microwave sources is collected by means of a coolant circuit and transported to the r areas adjacent the leading edge for permanent heating in order to keep the surfaces free from ice. The microwave sources are cyclically operated.Type: ApplicationFiled: October 10, 2003Publication date: September 9, 2004Inventors: Lambert Feher, Arno Pabsch

Patent number: 6485594Abstract: A method for producing sections in sandwich structures of fiber composites is provided, as well as the structures. The method involves shaping sectional cores around a cut-out, applying bands circumferentially along the perimeter of the cut-out, and covering the sectional cores and to circumferential bands, with layers. The sandwich structure is then impregnated with resin.Type: GrantFiled: May 26, 2000Date of Patent: November 26, 2002Assignee: Deutsches Zentrum fur Luft und Raumfahrt e.V.Inventors: Arno Pabsch, Wilm Felix Unckenbold, Axel Herrmann

Patent number: 6257858Abstract: In a process for producing large-surface structural elements from fiber-reinforced composite materials by resin transfer moulding, a mold (2) that can be evacuated has a dimensionally stable part (4) and an elastically deformable part (6). The mold (2) has connections for injecting a resin mixture and connections to a pressure sink. A fibrous fabric (12) is set into the mold (2). Elongated pipes having a large supporting surface (22) and a cavity (24) that extends in the longitudinal direction of the pipes above the supporting surface (22) are provided on the surface of the fibrous fabric (12) opposite to the dimensionally stable mold part (4) to inject the resin mixture and to ensure the connection with the pressure sink. The supporting surface (22) of the pipes has a narrow slit (26) which extends substantially over the whole length of the pipes and which is in communication over its whole length with the cavity (24).Type: GrantFiled: June 19, 1998Date of Patent: July 10, 2001Assignee: Deutsches Zentrum fur Luft-und Raumfahrt e.V.Inventors: Arno Pabsch, Christof Sigle, Matthias Piening

Patent number: 5924649Abstract: An aircraft with supporting wings including wing shells with good shear strength made of fibrous composite materials, particularly fiber-reinforced plastics, having members taking up tensile and compressive forces on the inside of the wing shells. The members have unidirectional fibers extending longitudinally of the wing, and fixing elements which can be joined detachably to fuselage attachments are provided on the members at the root end of the wing. Stringers are constructed on the inside of the wing shells and spaced longitudinally of the shells, their fiber component being formed by a fiber layer joined to the fiber layer of the wing shell. Fiber bundles are arranged between spaced stringers as unidirectional stiffening elements. The fiber bundles are embedded in the synthetic resin matrix of the plane load-bearing structure and extend longitudinally of the supporting wing.Type: GrantFiled: August 9, 1996Date of Patent: July 20, 1999Assignee: Deutsch Forschungsanstalt fur Luft-und Raumfahrt e.V.Inventors: Matthias Piening, Arno Pabsch, Christof Sigle
