Rotor wing or rotor blade for power production for vertical wind-power plants or turbines, has inflow zone follows cross section of basic form of counter-rotating spiral according to principle of golden section

摘要

The rotor wing or rotor blade has an inflow zone follows a cross section of basic form of a counter-rotating spiral according to the principle of a golden section. Axis parallel arrangement of rotor blades and axis of rotation, particularly a helical curvature of the rotor blades, are provided on a cylindrical outer surface.
