A damping system for damping vibrations of a rotor blade of a rotor of a turbomachine is disclosed. A damping element is guided on a support such that the damping element is radially outwardly movable during a rotation of the rotor and is contactable with a lower platform area of a rotor blade. A circumferential contact surface is formed by an elevation on the lower platform area, where the circumferential contact surface is a limit stop for a movement of the damping element.

Damping element and method for damping rotor blade vibrations, a rotor blade, and a rotor

A coupling elementis disclosed for arrangement between shroudsof adjacent rotor blades, the coupling element having force-transmission surfacesfor bounding damping gapsbetween shrouds, and a rotor having at least one coupling elementof this type.

Coupling element for mechanically coupling blades and a rotor

An integrally bladed rotor disk () for a turbine, including rotor blades (), which are joined in a substance-to-substance bond to a disk element (), and a sealing device () for preventing or reducing the extent to which cooling air is able to flow from a high-pressure side () of the rotor disk () through openings () on the rotor disk () to a low-pressure side () of the rotor disk ().

Integrally bladed rotor disk for a turbine

The invention relates to a gas turbine blade (), in particular a compressor blade and/or turbine blade for a turbomachine, wherein the gas turbine blade () comprises at least one receptacle () for the form-fitting arrangement of a connecting element, by means of which a mechanical load can be introduced into gas turbine blade (). The invention further relates to a shrouding band segment () for arrangement on a gas turbine blade (), a connection system having a gas turbine blade () and having a connecting element, a method for connecting a gas turbine blade () to a connecting element, and a rotor for a turbomachine having a rotor disk () joined to a blade ring or having a rotor ring joined to a blade ring.
