<p>The wind turbine is provided for the transformation of the energy of a free flow and is comprised of a rotor rotating about a vertical axis, flow collector blades being arranged at the ends of the two identically oriented rotor arms. The flow collector blades (1') are provided in their medial articulation area (2) at the rotor arms (3) with an aerodynamically shaped protuberant nose (4), by means of which the respective flow collector blade is articulated at the end (5) of the rotor arm. In a recess (6) of the nose (4) there is arranged a small corresponding flow body (7) which is secured at the end (5) of the rotor arm. An orientable stop blade (9) which may be brought by means of stops (8) to a stop effect with the flow collector blade is provided before or after the flow body (7). The rotor arms (3) are configured so as to be brought with respect to the rotor axis into a plane including the rotor axis, from an inclined position maintained by means of the action of a counter pressure element in horizontal position under the effect of the centrifugal force of the rotor. A circular element stabilizing the turbine is arranged on the rotor axis.</p> |
