Development of sail type wind turbine for small wind speeds

Abstract

The present article is devoted to the development and establishment of low-power multiblade wind turbines for generate electricity using blades with dynamically changeable form. The prototype of wind turbine with dynamically changeable surface shaped blades was developed. The aerodynamic characteristics of the prototypes of blades of a wind turbine with dynamically changeable form were investigated. As a result of experimental researches dependence of the aerodynamic traction force from the speed and attack angle of wind flow, the rotation frequency of the wind turbine from the flow speed were obtained.
