Gorlov Helical Turbine
The turbine consists of one or more long helical blades that run along a cylindrical surface like a screw thread, having a so-called airfoil or ‘airplane wing’ profile. The blades provide a reaction thrust that can rotate the turbine faster than the water Sow itself. The turbine shaft (axis of rotation) must be perpendicular to the water current, and the turbine can be positioned either horizontally or vertically. Due to its axial symmetry, the turbine always develops unidirectional rotation, even in reversible tidal currents. This is a very important advantage, which simpliRes design and allows exploitation of the double-action tidal power plants.
