Abstract (en)

[origin: EP1862638A1] The method involves blocking new bridge segments (20) in the heat accumulation segment carrier (14). A heat accumulation segment carrier is provided, concentric to the axis of the rotor (10), in axial direction in front of and/or behind the rotor blades and below which an internal closed cooling air channel (16') proceeds concentric to the axis. The new bridge segments are protected against forces acting radially outwards.
