Publication number: 20140286691Abstract: A fuselage structure for a means of transport includes at least two fuselage segments, in each case including an outer skin with an end edge. In a connecting region of two fuselage segments the end edges of the fuselage segments are spaced apart from each other. Connecting elements establish a mechanical connection between two fuselage segments. Conducting structure-borne sound is reduced by multiple deflection of the sound path, and thus results in a reduction in structure-borne sound-induced noise in the cabin of the means of transport.Type: ApplicationFiled: March 18, 2014Publication date: September 25, 2014Applicant: Airbus Operations GmbHInventor: Wolfgang Gleine

Patent number: 8794018Abstract: A system for preventing icing in a conduit, as can occur in an aircraft's air conditioning system, includes at least one sensor for acquiring mechanical oscillations of the conduits, an electronic evaluation unit and an electronic control unit. The sensor is connected to the electronic evaluation unit, which knows characteristics relating to the oscillation behavior of the conduit and is equipped to compare the measured conduit oscillations with these characteristics, and through correlation to interpret them as conduit icing, and in the case of conduit icing to emit a signal to the control unit. If the operation-associated oscillations are inadequate, oscillations can be generated or amplified through an actuator. With this system an icing state within the conduit can be detected without the use of sensors located in the interior cross section of the conduit, which itself serves as a sensitive element.Type: GrantFiled: December 23, 2008Date of Patent: August 5, 2014Assignee: Airbus Operations GmbHInventor: Wolfgang Gleine

Patent number: 6587188Abstract: In a sensor arrangement for sensing temperature and strain, an optical fiber with a Bragg grating therein is arranged on a substrate and embedded in a cover layer. The fiber is initially adhered onto an adhesive carrier, which then positions and applies the fiber onto the substrate. The fiber is point-wise fixed onto the substrate by a binder applied through holes in the adhesive carrier. Next, the carrier is stripped off to leave the fiber on the substrate. A cover layer is applied over the fiber and the substrate. Temperature and strain variations are transmitted from the cover layer into the fiber as non-circularly-symmetrical strains. The strain and temperature can be independently determined using this single sensor, by feeding quasi-depolarized light into the fiber and measuring the overlapping birefringent reflections from the Bragg grating. The full width at half maximum value indicates the temperature, while the Bragg wavelengths indicate the strain and the temperature.Type: GrantFiled: February 2, 2001Date of Patent: July 1, 2003Assignee: Airbus Deutschland GmbHInventors: Wolfgang Gleine, Michael Trutzel

Patent number: 6536714Abstract: An elastically expandable hollow displacement element is secured to the rear surface of an aircraft wing slat. When the displacement element is contracted, the slat may be retracted onto the wing's leading edge. When the slat is extended, the displacement element is expanded to protrude convexly from the slat, thereby preventing vortex formation in the slat air gap and reducing aero-acoustic noise. A pressure control system for inflating and deflating the displacement element includes a bleed air line connected from the aircraft engine bleed air system to the displacement element, a shut-off valve and a pressure control valve interposed in series in the bleed air line, and a slat contour controller connected by respective signal lines to the valves, which control the quantity and the pressure of the bleed air supplied into the displacement element, for properly inflating the same.Type: GrantFiled: April 17, 2001Date of Patent: March 25, 2003Assignee: Airbus Deutschland GmbHInventors: Wolfgang Gleine, Knut Mau, Udo Carl

Patent number: 5875998Abstract: A method and an apparatus are provided for optimizing the aerodynamic effect of the airfoil of an aircraft by defined changes in camber. The method includes the following steps:a. determining the flow for the flight condition caused by the change in camber,b. comparing the ascertained characteristic values with stored nominal reference values for an optimal flow,c. forming differential values between the characteristic values and the stored nominal reference values,d. deriving actuator signals from the differential values, ande. changing the camber by motor, based on the actuator signals, for minimizing the differential values.The optimum wing flow is thereby maintained more exactly. For transonic wings, the position and strength of compression shocks is also effectively controlled, which leads to a reduction of the direct shock induced separation.Type: GrantFiled: December 19, 1997Date of Patent: March 2, 1999Assignee: Daimler-Benz Aerospace Airbus GmbHInventors: Wolfgang Gleine, Reinhard Hilbig, Hans-Joachim Wendt
