Publication number: 20230265868Abstract: A hydraulic locking device for an exoskeleton joint with an extendable and retractable hydraulic cylinder, a tank and a switching valve. The hydraulic cylinder is connected to the tank via a line arrangement and the switching valve is disposed in the line arrangement. The switching valve is switchable between a release position and a blocking position. The hydraulic cylinder is freely movable in the release position of the switching valve, and the switching valve prevents retraction of the hydraulic cylinder in the blocking position. The hydraulic locking device further comprises a housing, and the hydraulic cylinder is a plunger cylinder with a plunger cylinder housing and a plunger piston movably arranged in the plunger cylinder housing, the plunger cylinder being arranged within the housing. Further, an exoskeleton joint having such a hydraulic locking device is disclosed.Type: ApplicationFiled: February 10, 2023Publication date: August 24, 2023Inventors: Christian Hart, Julian Weber, Steffen Marx

Patent number: 10201845Abstract: The invention relates to a device and a corresponding method for manufacturing brush seals with obliquely positioned bristles. The method comprises the following steps: As the first step, a metal filament or wire (50) comprising a material for bristles is wound over two wire cores (42, 46) disposed at a distance from and running parallel to one another, to form a tightly packed metal filament or wire package (48). As the next step, the metal filament or wire package (48) is fastened to at least one wire core (42, 46). Then the region around at least one of the two wire cores (42, 46) is locally heated. Subsequently, at least one of the two wire cores (42, 46) is displaced.Type: GrantFiled: April 18, 2016Date of Patent: February 12, 2019Assignee: MTU Aero Engines AGInventors: Alexander Gindorf, Roland Huttner, Martin Fessler-Knobel, Julian Weber, Christoph Cernay

Patent number: 10094230Abstract: A brush seal system for sealing a clearance between components of a turbo engine that are movable in relation to one another, in particular of a thermal gas turbine, is disclosed. The brush seal system includes a brush seal housing, which accommodates at least one brush head of a brush seal, where the brush seal housing includes a first component having a cover plate section and a second component having a support plate section. The first component includes an axial flange forming a fish mouth seal on an end opposite the cover plate section. A thermal gas turbine having such a brush seal system is also disclosed.Type: GrantFiled: June 24, 2015Date of Patent: October 9, 2018Assignee: MTU Aero Engines AGInventor: Julian Weber

Patent number: 9920838Abstract: A brush seal for a gas turbine, in particular an aircraft engine, is disclosed. The brush seal includes a support ring which has a support plate and a support structure, where the support structure is arranged downstream with respect to the support plate. The brush seal also includes bristles which are arranged upstream with respect to the support ring, where ends of the bristles protrude radially inward beyond the support plate. The support structure yields when a scraping force acting radially outward occurs on a first lateral surface of the support structure, where the first lateral surface is directed radially inward, and the support structure does not yield when an axial operating force occurs on a second lateral surface of the support structure.Type: GrantFiled: July 2, 2015Date of Patent: March 20, 2018Assignee: MTU Aero Engines AGInventors: Stephan Klaen, Julian Weber, Frank Stiehler, Christoph Cernay, Thomas Hess
