The effect of changing the size of the blades on efficiency operation of a vertical-axial wind power plant

Abstract
The introduction of wind power plants makes it possible to provide electricity to remote territories during the construction of agricultural and industrial enterprises, peripheral settlements. In addition, it is relevant to provide long highways with electricity, especially when using electric vehicles. The article suggests studies that allow to increase the efficiency of a vertical-axial wind power plant, using blades using the principle of differential drag. It is known that the aerodynamic characteristics of the blades are the basis of the efficiency of the wind turbines of the Finnish scientist S.J.Savonius. The analysis of the aerodynamic coefficients showed that the increase in the overall aerodynamic coefficient of the blade, located under the action of the airflow along the course of the blade, should be greater, and when moving on the counterflow to the airflow, it should be the smallest. Such a change in aerodynamic coefficients is possible only with the transformation of the blade – with a change in its size and shape of the blade. At the same time, it is necessary to observe that such changes occur automatically without human influence. To do this, a spring was used, which was twisted under the influence of wind, and in the absence of wind pressure, the spring was restored and returned the shape and size of the blade to its original position. Changing the shape and size of the blade under the influence of wind increases the aerodynamic coefficients of the blade and increases the efficiency of the wind turbine.
