Описание изобретения

  • The invention relates to wind power and allows effectively convert the kinetic energy of the wind, after its (wind) accelerating, to electrical power.
    The multi-stage wind turbine, which allows multiple accelerate directed air flow (wind), even of most minimal speed, up to strong wind and convert it's energy into electrical power, is proposed. It is achieved due to modularity of installation, where the wind is accelerated within each module due to the processes of capturing the initial wind flow, injection-ejection and aerodynamic Coanda effect as well, by virtual necks and conical confusors nested one into another. The system of truncated cones and virtual necks with optimum aerodynamic sizes provides the capture of the airflow not only perpendicular to the base of these cones, but also from lateral sides of these cones. Moreover, the area of wind flow capturing by lateral surface of this system, depending on the number of stages, several times exceeds the area of wind flow capturing by base of first confusor from side of wind flow. In proposed installation for increase of output power, three parameters are used at relatively small sizes of airscrew. In this case, the wind flow, which is captured by working part of the wind turbine, is compressed by all sides, increasing the speed of the directed airflow, acting on the airscrew. All turbine stages, except the last stage, represent the not full Venturi tubes consisting of a confusors and virtual necks. The last stage represents the classical Venturi tube, consisting of confusor, neck and diffusers. The airscrew is located within the neck of the Venturi tube. Turbine is equipped with a weather vane and means of protection from destruction during hurricane wind.
