Abstract
Official abstract text for this publication.
A sealing device for an integrally bladed rotor basic body of a turbomachine to suppress a gas exchange between a hot gas stream and a cooling air stream in the radial direction in contact areas of adjacent moving blades, including a plurality of sealing elements activatable by centrifugal force, which may be situated in the area of channels which extend from a high-pressure side to a low-pressure side and are peripherally delimited by the moving blades, an integrally bladed rotor basic body having such a sealing device, and a turbomachine having such an integrally bladed rotor basic body.
First claim
Opening claim text (preview).
What is claimed is: 1. A sealing device for an integrally bladed rotor basic body of a turbomachine for suppressing a gas exchange between a hot gas stream and a cooling air stream in a radial direction in lateral contact areas of adjacent moving blades, the sealing device comprising: a plurality of sealing elements activatable by centrifugal force and situatable in an area of channels extending from a high-pressure side to a low-pressure side and peripherally delimited by the mov…
