Abstract: The present invention generally relates to a runner unit of a tidal power plant, and more particular to a device for reversing a blade of the runner unit. The device according to the invention is lighter and more efficient with respect to known solutions which involve articulated mechanisms as it is based on an auxiliary servomotor including a reciprocating linear rack which acts on the blade to be reversed.

Abstract: A hydro turbine with a runner unit allows adjusting the gap clearance downstream and between the runner end tip portion and the inner edge of the blades. This gap clearance may depend on the angular position of the runner blades.

Abstract: A runner for a tidal power plant, comprising a hub body provided with openings for receiving blades, individual rotating means for rotating each blade with respect to the hub body, around an axis that is perpendicular to a rotation axis of the runner. The rotating means include at least one linear servomotor or an electric motor capable of rotating a corresponding blade independently of the other blades, over an angle superior or equal to 180° around its axis.
