The present invention relates to wind energy and can be used to harvest and convert kinetic wind energy into electricity with higher efficiency.

Wind turbine that improves the efficiency of converting wind energy into electrical energy by implementing mechanical design features which harness the entrainment effect by using main rotor blades that are mounted at some distance from the center axis of rotation to allow airflow to pass through its center and to be accelerated by any means (jet fan for example), thus creating higher velocity lower pressure air stream (according to Bernoulli’s law) behind the wind turbine increasing airflow (entrainment effect) through the main rotor blades.

The invention as claimed is a lift-based horizontal-axis wind turbine, the design of which provides higher performance efficiency by extracting more energy from the airflow and at better coefficient of performance and converting it into electrical energy, compared to conventional lift-based horizontal-axis wind turbines of the same turbine rotor diameter.

The invention relates to a wind turbine that includes a rotor rotating about a horizontal axis of rotation substantially parallel to the direction of the wind, the rotor having a front face facing into the wind and substantially perpendicular to the axis of the wind, and a rear face situated toward a support of the rotor. At least two distinct families of blades are distributed on the rotor, each family of blades including at least two blades having a free end and a blade root end connected to said rotor. Each family of blades includes a catching blade guiding the wind toward a force blade having a surface arranged substantially perpendicular to the axis of the wind, the blade root ends of each family of blades are successively offset on an exterior surface of the rotor along the axis of rotation thereof.
