In this research, Blade Element Momentum theory (BEM) is used to design a HAWT blade for a 300 kW horizontal axis wind
turbine. The airfoil is Risø, produced by RISØ National Laboratory, Denmark, for a class of 300KW wind turbines. Design
parameters considered here are wind tip speed ratio, nominal wind speed and diameter of rotor. BEM is used for obtaining
maximum lift to drag ratio for each elemental constitution of the blade. Obtaining chord and twist distribution at assumed tip
speed ratio of blade, the aerodynamic shape of the blade in every part is specified which correspond to maximum accessible
power coefficient. The design parameters are trust coefficients, power coefficient, angle of attack, angle of relative wind, drag and
lift coefficients, axial and angular induction factors. The blade design distributions are presented versus rotor radius for BEM
