Abstract (en)
[origin: EP2505784A1] The rotor has moving blades (8) that are located adjacent to one another in a circumferential direction (19) with respect to rotation axis. Several intermediate pieces (14) are provided in reception slot between two adjacent ones of moving blades. Each intermediate piece is provided with an outer face having curved end wall contour (17) with concave curvature in an axial sectional plane of rotor. The outer faces (15,17) of blade roots (13) and intermediate pieces are adjacent to one another and are aligned radially in the circumferential direction. An independent claim is included for method for modernizing rotor of turbomachine.
