BLADED GAS TURBINE ROTOR

摘要

The present invention relates to a bladed rotor for a gas turbine, with a body and a plurality of rotating blades where contact regions of a cylindrical surface of the body and front faces of the rotating blades are joined together cohesively. At least one of these contact regions and/or at least one of these front faces has at least one blind hole, in which at least one impulse body is arranged with play of movement and which is sealed and rotating blades are joined with the cylindrical surface. Alternatively, the body and rotating blades are manufactured integrally with one another by machining, and at least one blind hole extends from an inner surface of the body facing away from the blade out to one of the rotating blades, at least one impulse body being disposed with play of movement in this hole, and this hole is sealed.

主权项

1. A bladed rotor for a gas turbine, comprising:
a basic body (10) and a plurality of rotating blades (20, 30), wherein contact regions (12, 13) of a cylindrical surface (11) of the basic body and front faces (21, 31) of the rotating blades are joined together cohesively, and at least one of these contact regions and/or at least one of these front faces has at least one blind hole (40), in which at least one impulse body (50) is arranged with play of movement and which is sealed (41), in addition to the joining of the rotating blades with the cylindrical surface.
