Abstract
A seal arrangement for a turbo-engine, for sealing a peripheral gap between a rotor and a stator is provided. The stator a seal holder provided with at least one groove for respectively receiving a segmented, dynamic seal. Segments of the dynamic seal are made up of a plurality of brush seal segments, and free ends of bristles of the brush seal segments extend in the radial direction project from the respective groove and lie on the rotor. The or every groove for receiving the brush-type seal segments is designed without an undercut, the brush-type seal segments being received in the respective groove without an undercut in a positive manner.

A seal system for a turbo-engine, for sealing a circumferential gap between a rotor and a stator, the stator comprising a seal holder having at least one circumferential groove for receiving a segmented dynamic seal, the segmented dynamic seal including a plurality of segments;
- each of the segments being brush seal segments having bristles, the bristles having free ends, the free ends of the bristles extending in a radial direction projecting from the at least one groove and resting on the rotor, the at least one groove being a groove without undercut, the brush seal segments being positively secured in the groove.
A seal system for a turbo-engine, for sealing a gap between the radial inner ends of stationary guide vanes and a rotor, the stationary guide vanes comprising a seal holder having at least one circumferential groove for receiving a segmented dynamic seal, the segmented dynamic seal including a plurality of segments;
- each of the segments being brush seal segments having bristles, the bristles having free ends, the free ends of the bristles extending in a radial direction projecting from the at least one groove and resting on the rotor, the at least one groove being a groove without undercut, the brush seal segments being positively secured in the groove.
A seal system for a turbo-engine, for sealing a gap between the radial outer ends of rotating rotor blades and a stationary housing, the housing comprising a seal holder having at least one circumferential groove for receiving a segmented dynamic seal, the segmented dynamic seal including a plurality of segments;
- each of the segments being brush seal segments having bristles, the bristles having free ends, the free ends of the bristles extending in a radial direction projecting from the at least one groove and resting on the rotor, the at least one groove being a groove without undercut, the brush seal segments being positively secured in the groove.
A seal system for a turbo-engine for sealing a gap between two stator-side components comprising a first stator-side component and a second stator-side component, the first stator-side component having at least one groove for receiving a static seal, the static seal being designed as a brush seal having bristles, the bristles having free ends, the free ends of the bristles projecting from the groove and resting on a second stator-side component,
- the groove being a groove without undercut, the brush seal being secured in the groove with a radial clearance.
