The Aerodynamic performance characteristics of a horizontal axis wind turbine (HAWT) using by NACA44xx, LSO4xx, and NACA64-415 aerofoils were investigated theoretically by an analysis involving a combination of momentum, energy, and blade element theory by means of the strip element method, based on the detail date of C_L, C_D characteristics of the employed blades analyzed by the soft of Java Foil, and experimentally by the use of a subscale model. The characteristics of HAWT employed NACA44xx, LSO4xx and NACA64-415 aerofoil blades for the different types of the blades such as blade dia. D and number N, chord length l, twist pitch angle θ, and for large scale units are discussed and cleared by reference to the power, torque and thrust coefficient, C_p, C_q, C_T, and the tip speed ratio λ from the point of view of the optimum design and controlling.
