Abstract

The invention relates to a wind turbine that does not produce a negative visual impact, dampens noise and is not dangerous. The solution found by the inventors is to insert the wind turbine blades into a wind concentrator. Specifically, the wind concentrator is a vertical structure having an annular cross section comprising nozzles through which the wind circulates. The wind turbine is formed by a motor system composed of the wind concentrator and blades firmly connected to a drive shaft. All the nozzle outlets face the same direction of rotation of the turbine, allowing the rotation speed of the blades to be increased and, therefore, energy efficiency to be increased. The wind turbine also comprises a drive wheel (9) firmly connected to the drive shaft (4), support arms (7) and a plurality of generators (8) interlinked to the drive wheel and perimetrally disposed on the drive wheel.
