A COMPARATIVE STUDY OF STATIC STRUCTURAL ANALYSIS ON VERTICAL AXIS WIND MILL MADE OF ALUMINUM AND GFRP

Abstract

This paper studies the potential for installing roof-mounted savonius type Vertical Axis Wind Turbine (VAWT) systems on house roofs with the goal of maximizing the efficiency and reducing the cost and weight. Wind turbine efficiency depends on the material of the blade, shape of the blade and angle of the blade. So material of the turbine blade plays a vital role in the design of wind turbine. Most of the wind turbine blades are made of mild steel and stainless steel which has more density. This is main cause for huge weight. It has high corrosion and less fatigue strength. The steel can be replaced by GFRP or aluminum material to reduce the weight, to improve corrosion resistance and fatigue strength, to make them more affordable, efficient, durable and sustainable. In this paper, Aluminum and GFRP material has been used to design savonius wind blades of 1 m height and 0.5 m chord length with 4 different arc radiuses.
