Axial turbo engine rotor with sealing disc

摘要

The axial turbo machine rotor, particularly gas turbine, has a rotor body formed in a rotation symmetrical manner around the rotor axis, a rotor blade ring having a multiple rotor blades fixed to the rotor body by a blade foot. A sealing disk (7) is formed in a rotation symmetrical manner around the rotor axis that is arranged to the outer edge (10) adjacent to an axially extending protrusion (6) of the blade foot, so that a hollow space (9) is formed between the blade foot and the sealing disk. A sealing ring (14) is formed by multiple sealing ring segments arranged in circumferential manner.
