Design of Naca63215 Airfoil for a Wind Turbine

Abstract

The ultimate objective of the work is to increase the reliability of wind turbine blades through the development of the airfoil structure and also to reduce the noise produced during the running period of the wind turbine blades. The blade plays a pivotal role, because it is the most important part of the energy absorption system. Consequently, the blade has to be designed carefully to enable to absorb energy with its greatest efficiency. In this work, Pro/E, Hypermesh software has been used to design blades effectively. NACA 63-215 airfoil profile is considered for analysis of wind turbine blade. The wind turbine blade is modeled and several sections are created from root to tip with the variation from the standard design for improving the efficiency. For the further improvement required in the efficiency of the wind turbine the winglet is to be included at the tip of the blade which would help in increasing the efficiency and reducing the noise produced from the blades in working condition. The existing turbine blade and the modified blade with the winglet are compared for their results.
