Design and Fabrication of Flipping Blade Vertical Axis Wind Turbine

Abstract

Wind energy is one of the renewable sources, used to generate an electric power generation. The search for environment friendly, sustainable energy has promoted in this industrial world. The present global technological society is depended on the availability of energy. The development of industry, agriculture and transportation, etc. is totally depended on the availability of power. The cost of energy is increasing day by day due to the increase in the demand of power and depletion of the resources, which are used in the generation of electricity. So, it is very essential to make use of the nonconventional sources of energy like wind energy, solar energy, tidal energy, etc. Wind energy is used to generate electrical power by rotating the rotor shaft by the conversion of kinetic energy of wind into rotational energy of the shaft. The performance of wind turbine can be increased by increasing the drag force on the blade. This paper introduces a new mechanism developed by us and this mechanism is used to change the blade position during running condition to increase the resultant drag force on turbine blade. This mechanism is simple and also decreases cost of wind turbine by using flat blades.
