Exploration of Materials Used to Design Airfoil the Vertical Axis Wind Turbine

Abstract

This paper presents the study about role of materials to design airfoil on the analysis of a Vertical Axis Turbine (VAWT) with strength and reliability of airfoil that attached to its supporting arm joint to the main shaft of the VAWT. The materials used in production of airfoil blade wind turbine have been made resistive, cheeped, low weight. The materials Aluminum Composite has light weight, low tensile strength, and good reliability. PVC is very light weight material. This composite material has good thermo-mechanical and chemical properties. The velocity and pressure field which affects the efficiency of different airfoil angles of attack at a series of VAWT rotation angles can be obtained. The position the net force on the airfoil can also derived from the formula based on the pressure field and the airfoil geometry. Hence it is, directly related to the efficiency of the VAWT.
