A leaf seal for sealing off a shaft rotating around an axis, particularly in a gas turbine, is disclosed. The leaf seal includes a plurality of leaves arranged spaced apart from one another, where the leaves are produced integrally with a basic element supporting the leaves by a generative production process. A process for producing a leaf seal for sealing off a shaft rotating around an axis is also disclosed.

A device for attaching seal elements in a recess, particularly in an installation groove designed in a flow machine, is disclosed. At least one fixing body is arranged between a seal carrier element and a clamping body assigned to the seal carrier element, where the fixing body is integrally connected to the seal carrier element and the clamping body by bar-like connections that can be detached when subjected to a force. In addition, at least one plastic deformable structure is designed on the fixing body. An attachment method as well as a production method for the device is also disclosed.

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 () comprising a material for bristles is wound over two wire cores () disposed at a distance from and running parallel to one another, to form a tightly packed metal filament or wire package (). As the next step, the metal filament or wire package () is fastened to at least one wire core (). Then the region around at least one of the two wire cores () is locally heated. Subsequently, at least one of the two wire cores () is displaced.

The invention relates to a brush seal, in particular for the sealing of gaps occurring in turbomachines, including a plurality of individual fibers, individual wires or bundles of individual fibers or wires, wherein, in each case, at least two individual fibers or wires, and/or at least two fiber bundles or wire bundles are braided or twisted into a fiber or wire package. In addition, the invention relates to a method for producing a brush seal.

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.

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.

Brush seal

A brush seal system for sealing a gap between components of a thermal gas turbine that may be moved relative to one another includes a gas seal housing that receives at least one brush head of a brush seal and a support element by means of which a brush packet projecting from the brush head of the brush seal may be supported against flexing. The support element and the brush seal housing are embodied as separate components. The invention furthermore relates to a method for producing such a brush seal system and to a thermal gas turbine having such a brush seal system.

The invention relates to an apparatus () for securing sealing elements () in a recess (), more particularly in an installation slot in a turbomachine, having at least one sealing support element () comprising at least one sealing element (). At least one fixing piece () is fitted between the sealing support element () and a clamping piece () associated with the sealing support element (), and the fixing piece () is integrally joined to the sealing support element () and the clamping piece () by strut-like connections () that can be broken by the application of force. The invention also relates to a securing method and to a method for manufacturing the claimed apparatus ().
