Wind turbine blade design for low rotational inertia materials at variable speeds with different twisting angle using Q-Blade

In this current investigation, the comparison and analysis of two-dimensional model for aerodynamic characteristics of the wind turbine blade was studied. The aero profiles of NACA0008 and NACA0012H compared and simulate. NACA0012H aero profiles were transformed to three-dimensional model with variable twisting angles and compared with exhaustive literature. The blade element momentum (BEM) method was used for the calculations of aero profile’s lift, drag, pressure coefficients using Q-blade software. Coefficient of lift, coefficient of lift and drag ratio and Coefficient of moment is getting better result of NACA0012H from NACA008 this may be due more chord thickness. Power and coefficient of power is better in NACA0012H with 30° twisting angle with TSR and Thrust. A parametric report generated here showed advanced estimations of cutting edge aero foil and twist speed in Q-Blade programming. Power coefficient increase up to blade in three airfoils with different twist angle and finds the maximum power near to 10.0 TSR value.
