Patent number: 8191835Abstract: A wing of an aircraft has a mainplane, which has an upper face, a lower face and an aerodynamically shaped area. The wing has an additional airfoil which is articulated on the mainplane and can be extended from a retracted state with a slot area being opened between the mainplane and the additional airfoil. The wing also has a variable-position slot-varying apparatus which is arranged on the lower face, forms a part of the aerodynamic profile of the additional airfoil or mainplane when the additional airfoil is extended, and at least partially covers the slot area between the mainplane and the additional airfoil on the lower face when the additional airfoil is in the retracted state. The slot-varying apparatus can be varied between a curved configuration, in which it forms a part of an aerodynamic profile, and an extended configuration, in which it at least partially covers the slot area.Type: GrantFiled: December 11, 2007Date of Patent: June 5, 2012Assignee: Airbus Deutschland GmbHInventors: Boris Grohmann, Johann Reichenberger, Thomas Lorkowski

Publication number: 20100294893Abstract: The invention relates to an aerodynamic component, in particular a wing, a landing flap, a pitch elevator, a yaw rudder, a fin or tail. The aerodynamic component comprises an outer shell and at least one supporting element supporting said outer shell. A drive unit rotates the supporting element. A supporting region is created between the supporting element and the outer shell. The supporting region transfers deformation forces from the drive unit via the supporting element to the outer shell. The supporting element is designed and configured for changing the distance of the supporting region from a longitudinal plane of the aerodynamic component with a rotation of the supporting element. The outer shell comprises an elastic deformation region. The elastic deformation region is elastically deformed by the deformation forces with a rotation of the supporting element.Type: ApplicationFiled: May 24, 2010Publication date: November 25, 2010Applicant: DEUTSCHES ZENTRUM FÜR LUFT- UND RAUMFAHRT E.V.Inventors: Olaf HEINTZE, Hans Peter MONNER, Markus KINTSCHER, Johannes RIEMENSCHNEIDER, Thomas LORKOWSKI

Publication number: 20090001223Abstract: A flexible control surface (1; 11, 14) comprises at least two actuators (3), which act on the control surface (1; 11, 14) at different points of action (2) which are offset laterally with respect to the circulating-flow direction (6) with respect to one another. The at least two actuators (3) are designed such that the points of action (2) can be deflected differently when the actuators (3) are operated at the same time. It is thus possible to elastically deform the control surface (1; 11, 14), in particular along the span width direction (9), without kinks, in which case it is possible to achieve uniform transitions along the control surface laterally with respect to the flow direction (6). The invention makes it possible to reduce vortices and noise induced by the control surface.Type: ApplicationFiled: December 20, 2006Publication date: January 1, 2009Applicant: Airbus Deutschland GmbHInventors: Boris Grohmann, Peter Konstanzer, Thomas Lorkowski

Patent number: 6371415Abstract: An aerodynamic component such as a helicopter rotor blade has an aerodynamic flow profile, a free end and a mounting end forming a blade root for attachment to a rotor mast. A blade section between the root and the free end has a leading edge and a trailing edge as viewed in the flow or chord direction. The blade is enclosed on its suction side and its pressure side with a respective skin. A nose flap or leading edge flap is secured to the leading edge by a bearing or hinge. The blade tilting angle is adjustable by piezo-drive elements arranged in at least one pair forming an actuator for each nose flap. The piezo-elements of a pair are arranged in the chord direction one behind the other and the pair is secured to the body of the blade by a fixed point positioned between the elements of a pair. The expansion and contraction from the piezo-element closer to the trailing edge is transmitted to the flap by a push rod.Type: GrantFiled: September 11, 2000Date of Patent: April 16, 2002Assignee: DaimlerChrysler AGInventors: Thomas Lorkowski, Frank Hermle, Peter Jaenker
