Patent number: 11780558Abstract: A support stay is provided to improve failsafe configurations for movable parts of an aircraft. The support stay supports the movable part with a primary body and a separate secondary body. The primary body and the secondary body provide separate load paths. The secondary body is attached to the primary body by a mechanical connection, e.g., rivets. If one of the bodies becomes structurally compromised, for example by a crack, this configuration does not transfer shear load between the primary and secondary body, so that the other body does not become structurally compromised.Type: GrantFiled: February 25, 2021Date of Patent: October 10, 2023Assignee: Airbus Operations GmbHInventors: Dort Daandels, Markus Gibbert, Blazenko Coskovic

Publication number: 20230271719Abstract: A method and a system for monitoring a laminar flow on a surface of an aircraft is disclosed including observing a surface of an aircraft by an optical sensor, and processing an image data of that surface by an image processing system in order to determine an actual extend of a laminar flow on the surface. The actual extend of the laminar flow on the surface is compared with a previous extend of the laminar flow on the surface, and/or with a potential maximum extend of laminar flow on the surface determined from flight parameters of the aircraft. A reduction or a possible optimization of the laminar flow is detected and further processed to improve the laminar flow.Type: ApplicationFiled: February 24, 2023Publication date: August 31, 2023Inventors: Bernhard SCHLIPF, Dort DAANDELS

Patent number: 10836471Abstract: An aircraft structure component for laminar flow, the aircraft structure component having an outer skin with an aerodynamic surface, wherein the aerodynamic surface has a leading edge portion and a downstream portion adjacently downstream from the leading edge portion, and wherein the downstream portion of the aerodynamic surface includes a paint layer that is not present in the leading edge portion, so that an edge line is formed between the leading edge portion and the downstream portion by the beginning paint layer. An object, to provide an aircraft structure component that allows for a reduced aerodynamic drag, is achieved in that the edge line has a ramp-shaped cross section, wherein the thickness of the paint layer increases from a starting point over a predetermined ramp length to a saturation point where the full thickness of the paint layer is reached.Type: GrantFiled: October 31, 2017Date of Patent: November 17, 2020Assignee: Airbus Operations GmbHInventors: Bernhard Schlipf, Dort Daandels
