Development a sail type wind turbine for autonomous energy supply according climate conditions

Abstract

The paper discusses the problem of creating autonomous power supply system based on renewable resources according to climatic conditions. The authors studied the characteristics of climate and wind energy potential in Kazakhstan and Latvia and considered the possibilities of creation of a device to convert wind energy at low speed wind. The paper describes an experimental model of a wind turbine with flexible sails. Initial tests of a sail type wind turbine model with dynamically changeable sail shape were carried out at a wind tunnel. The dependencies of the drag force and traction force at various speeds and directions of airflow were obtained. The assessment of the prospects for use of small wind turbines for individual energy supply in both countries was considered.
