Abstract (en)

[origin: EP2299060A1] The rotor (1) has a turbine blade and a safety mechanism (7) for axial and radial safety of the turbine blade, where a blade groove and the turbine blade are provided with a turbine blade base (3). The blade groove and the turbine blade base are formed in such a way that the turbine blade base is adapted in the blade groove. The safety mechanism has a shear pin (8), which protrudes into a bore (15) in the turbine blade base.
