UNDERWATER POWER PLANT COMPRISING A WATER TURBINE WITH BIDIRECTIONAL FLUID FLOW AND UNIDIRECTIONAL ROTATION

摘要

The invention relates to an underwater power plant comprising an electric generator and a water turbine with bidirectional fluid flow and unidirectional rotation, said turbine comprising a plurality of turbine blades that have a teardrop-shaped profile over at least a portion of their longitudinal extension. The invention is characterized in that the water turbine comprises a passive mechanism to control the pitch angle of the turbine blades, wherein every turbine blade is assigned a swivel axis situated between the inflow profile nose and the threading line of the hydrodynamic centers.
