Abstract

In the report will be presented the investigation results of the working model of rotors with variable geometry parameters in dynamics. Because of aerodynamic and economic calculations, the effectiveness of use of such designs for powerful wind stations is proved. The analysis of various designs and methods of selection of that or other design for various conditions of operation of wind installations in wide range of the wind speed change is given.
Also rather effective by cost-price method of accumulation of wind energy will be suggested that is the topical world problem and for development of which are annually spent some hundreds of millions of US Dollars.
