Abstract (en)
[origin: EP1253293A2] The fixing device fixes a turbine blade (3) to the rotor (2) of a turbine. The blade has a foot, an aerofoil (32) and a platform (31) between these, with at least two side flanks (33, 34). Each blade has resting surfaces (52) aligned parallel to the rotor axis (4) to act with the blade foot extending into the circumferential groove (1).
