An Analysis of Lift and Drag Forces of NACA Airfoils Using Python

The aerodynamic Airfoils of wind turbine blades have crucial influence on aerodynamic efficiency of wind turbine. This involves the selection of a suitable Airfoil section for the proposed wind turbine blade. Lift and Drag forces along with the angle of attack are the important parameters in a wind turbine system. These parameters decide the efficiency of the wind turbine. In this paper an attempt is made to study the Lift and Drag forces in a wind turbine blade for NACA0012, NACA4412 & NACA6412 Airfoil profile is considered for analysis. Data for the Angle of Attack, Co efficient of Lift and Drag of NACA Airfoil taken from NACA Airfoil Tool. Lift and Drag Forces analysis for different parameters is carried out using PYTHON(x,y) 2.7.9.0 programming. xlrd library used to read the Airfoil data from excel file.
