Abstract (en)
[origin: EP1580404A2] Each rotor (1, 2) has an expansion ring with radially movable upstream blades (5) and radially movable downstream blades (7) connected to it. The ring has the same expansion properties as the rotor. The outer platforms (9, 11) on the blades are connected via an axial bridge (16) which is fixed in the rotor circumferential direction and connected radially to the turbine outer casing (10). The intermediate blades (6) and rotor shroud sections (8a, 8b) are secured to the bridge. The bridge comprises two bridge half-sections (16, 17) connected to each other and the intermediate blades are integrally connected to the second half-section.
