Publication number: 20100090068Abstract: The present invention relates to an aircraft with wings whose maximum lift can be altered by controllable wing components. By means of a regulating device, depending on flight state parameters and the actually measured load on the wings, wing components are acted upon such that, as a precautionary measure, the maximum possible aerodynamic lift does not exceed a desired upper limit value.Type: ApplicationFiled: December 17, 2009Publication date: April 15, 2010Applicant: Airbus Operations GmbHInventors: Alexander van der Velden, Roland Kelm, Josef Mertens

Publication number: 20080220310Abstract: Anode-supported high-temperature fuel cells with a substrate and an anode of stabilised zirconium dioxide and metallic nickel can be destroyed by air penetrating on the fuel gas side. Reoxidation causes the volume of the nickel in the anode to change. The resultant mechanical stresses may destroy the gas-impermeable electrolyte. The invention provides oxygen scavengers that can be produced at low cost for the anode, which more effectively bind the oxygen that penetrates on the fuel gas side than oxygen scavengers according to the prior art.Type: ApplicationFiled: August 5, 2006Publication date: September 11, 2008Applicant: Forschungszentrum Juelich GmbHInventors: Josef Mertens, Norbert Menzler, Hans Peter Buchkremer, Detlev Stoever

Patent number: 6415510Abstract: A method of fabricating an aircraft leading edge nose structure includes the following steps. Parallel strengthening members are welded onto a flat planar outer skin sheet. Two forming tool members having appropriately shaped outer contours contact the inner surfaces of the strengthening members, and are then pivoted and shifted toward each other so as to bend the outer skin sheet into a parabolic shape along the curved contour defined by the forming tool members. The resulting bent outer skin sheet with the strengthening members welded thereon is secured into a negative mold. To provide boundary layer suction, a perforated throttling sheet, inner ribs, and a non-perforated inner skin sheet may be successively secured by sealant and blind rivets onto the pre-bent structure of the outer skin sheet and the strengthening members. The finished structure is then removed from the mold.Type: GrantFiled: February 8, 2001Date of Patent: July 9, 2002Assignee: Airbus Deutschland GmbHInventors: Josef Mertens, Henri Lajain
