WINDKRAFTANLAGE MIT H-ROTOR

摘要

The invention concerns a wind turbine with a Darrieus H-rotor consisting of at least two airfoil-section rotor blades (11) disposed symmetrically about the axis of rotation and rotating parallel to each other and to the axis of rotation. The blades have start-assist flaps (12) located at least at one end of each blade, the flaps pivoting out, either self-actuated or power-driven, against a stop about an axis approximately at right angles to the axis of rotation.
