Wind turbine optimization through optimal blade shape design for low wind speeds

Current electricity needs continue to rely on depleting fossil fuels such as fuel and coal. The current government effort is find non-fossil alternative energy sources. Wind one of the efforts use ecologically friendly renewable energy. Studies development new are now undertaken. One them a series research utilization wind in numerous places Indonesia through construction turbines. blade that explicitly makes contact with most critical sections turbine. shape airfoil determines whether or not used. focus this was determine optimal type by comparing coefficient power (Cp), maximum power, lowest produced various NACA (National Advisory Committee for Aeronautics) airfoils. 4410, 4412, 4415 airfoils were employed study.
