Abstract
A damping arrangement for a blade () of an axial turbine, in particular a gas turbine, includes a damping element () which is arranged in a recess () in the blade aerofoil () of the blade () and frictionally dampens the vibrations of the blade (). In such a damping arrangement, simplified manufacture and assembly and a reliable and effective function are achieved by the recess being configured as a cavity () extending in the radial direction through the inside of the blade aerofoil (), the damping element () being inserted in the radial direction into said cavity ().
