20120286518 | Maritime Current Power Plant Park and a Method for Its Production - The invention relates to a maritime current power plant park, comprising several maritime current power plants which respectively comprise a rotor-like water turbine and an electric generator which are connected by means of a drive train, with the drive train comprising bearing components for supporting the rotor-like water turbine. | 11-15-2012 |
20120301294 | TURBINE BLADE FOR A WATER TURBINE WITH BI-DIRECTIONAL FLOW - The invention relates to a turbine blade for a water turbine, comprising, at least over part of its length, a curved profiled element having a median line created point-symmetrically in relation to a point of symmetry on the chord of the profiled element, half-way down, in such a way as to form an S-shaped curve. The median line splits the profiled element into a first side and a second side. The invention is characterised in that the turbine blade comprises an overflow device between the first side and the second side of the profiled element. | 11-29-2012 |
