Patent
CA 2681992
The invention relates to an underwater power plant which comprises a propeller- shaped water turbine in horizontal rotor configuration with a plurality of rotor blades which are fastened to a revolving unit, with each rotor blade being associated with a swivel axis which extends substantially along the respective rotor blade, with the rotor blades being arranged elastically about the swivel axis at least in sections of the longitudinal extension concerning a torsion and/or the fastening of the rotor blades to the revolving unit enabling a rotation of the rotor blades about the swivel axis, and the position of the swivel axis is chosen relative to the profile shape of the rotor blades in such a way that hydrodynamic forces acting during operation on the rotor blade generate a moment which is directed in the feathered pitch position and the centrifugal forces originating during the rotation cause restoring centrifugal moments on the rotor blade against the feathered pitch position.
