  • the subject of the invention is drum vertical axis wind turbine.
  • the solution, as described in the invention, significantly increases the efficiency of a wind engine by reducing the braking torque on the rotor wings.
  • the vertical axis wind turbines known so far in applications or publications, are based on Darrieus or Savonius models or modifications and reaction turbines with drum rotor, with various solutions of wings and wheels.
  • claim no. 328038 presents vertical axis wind turbine, with wings composed of movable segments.
  • the movable segments are fixed in a rotatable manner on horizontal axis in the top part of a segment, they take normal, vertical position and they create a plane. They are fixed in such a way, that each bottom edge of an upper segment rests on the top edge of a segment situated below, independently of number of segments on a wing. That ensures the deflection caused by wind pressure is possible in one direction only.
  • the wing creates minimal drag for the air flowing in this direction, in the opposite direction, when the wing is a plane surface, there is a maximal drag to the air flow.
  • Ail movable segments and the wings are assembled in such a way on a common rotation axis, that they can move to horizontal position in one direction only, e.g. only to the left, in such case, the turbine rotor will rotate to the right under the wind pressure, creating the torque on the axis (turbine shaft).

One wind rotor transfers the torque to the e.g. stator of the generator in the opposite direction to the rotation direction of the rotor of the generator.
  • the control of the driving blades aims at changing the aerodynamic lift and the forces transferred to the driving system, and as a result, at smooth regulation of the rotation number with respect to own axis during very strong wind, considering the double wind rotors system, with rotors rotating in the opposite directions in order to transfer the wind energy to other devices.
