Beschreibung
Zusammenfassung:	A blade arrangement with a rotor and a plurality of blades which are distributed in a ring along the circumference of the rotor is provided. Two immediately adjacent blades of the ring form a blade pair, between the blades of which a damping element is arranged, and wherein the respective damping element comes into contact with the two blades of the blade pair assigned to them during a rotation of the rotor about a rotor axis as a result of a centrifugal force which acts in the radial direction. In order to bring about frequency detuning of the oscillation properties of blades, as a result of which machining of the turbine blade becomes unnecessary, it is proposed that the blade ring has at least two blade pairs with different damping elements.
