The deficiency of traditionally used wind wheels is in their direct power of rotation at the main shaft of the wind turbine, which requires lengthening the blades in order to increase the capacity of the wind turbine. As such, traditionally used rotors have reached their technical limits (the length of the blade is more than 60 meters and the mass exceeds 7 tons).
Kazakh inventors Shaikenov B. and Shaikenov E.B. designed the new form of the wind wheel. The blade in the invented rotor design consists of two parts: a short root part with an elbow bend and a long wing-shaped part. The short root part of the blade is divided into an axial segment, which is secured to the hub mounted on the main shaft of the wind turbine and a sleeve segment, connected at 30-600 angle, thereby creating the elbow bend. The long wing-shaped part is connected to the sleeve segment through swiveling devices.
This new design feature creates effective wind current kinematics with high wind capture coefficient, due to special design of lever-shaped blades with two force application fulcrums and two points of force application on one side.
The invention opens up new horizons for wind power generation. It increases the coefficient of rotational force of the wind stream and allows using more powerful energy generators. The invention also allows reducing the blade’s length and decreasing the weight of the nacelle and the tower, thereby, increasing generation of annual unit of electrical power per unit of swept area, and reducing the cost of kilowatt-hour of energy for materials consumed and its construction.
