Abstract
A damping system for damping the vibrations of a blade union is provided. The blades arranged in a neighboring manner are coupled to one another via a coupling element, wherein the coupling element is arranged fixed in a first blade and extends into the second blade, wherein the coupling element is not arranged in the second blade but rather solely contacts there such that, as a consequence of centrifugal forces, a free end of the coupling element presses against the second blade and a friction force thus occurs, leading to an energy dissipation and vibrations being thus damped.

An arrangement, comprising:
- a first blade;
- a second blade which is arranged adjacent to the first blade;
- a coupling element,
- wherein the coupling element is fixedly arranged in the first blade and a part of the coupling element butts against the second blade,
- wherein the first blade includes a first blade tip,
- wherein the second blade includes a second blade tip,
- wherein the coupling element is arranged in a region of the first and second blade tip,
- wherein the first blade tip includes a first shroud and the coupling element is arranged in the first shroud,
- wherein the second blade tip includes a second shroud and the coupling element is arranged in the second shroud,
- wherein the first shroud and the second shroud include in each case a slot in which the coupling element is arranged, and
- wherein the slot is arranged at a side in the first shroud and in the second shroud.
