摘要： An axial turbine for a tidal power plant, including a hub with a rotor blade holder and a rotor blade with a blade fastening section having a longitudinal axis including a fastening stub, a radial fixing and an anti-rotation element. The fastening stub includes a contact surface supported against a complementarily shaped fixing surface on the rotor blade holder whose envelope is rotationally symmetrical to the longitudinal axis. The radial fixing secures the rotor blade fastening section against a withdrawal movement relative to the rotor blade holder in the direction of the longitudinal axis. The anti-rotation element is connected with a complementarily shaped rotational stop on the rotor blade holder with an effective area of the anti-rotation element being a component of the blade fastening section arranged separate from the radial fixing, and the radial fixing comprises fastening means that has a predetermined breaking point of the blade fastening section.
