Two types of wind turbine designs are horizontal axis wind turbine and vertical axis wind turbine, and the former type dominates in the wind turbine industry. Nowadays, focussed research is carried out to improve the aerodynamic profile of blades as well as enhancement in the quality of materials so that energy production can be increased along with cost reduction of operation and maintenance. Advances in the manufacturing of composite materials leads to better performances particularly in rough and corrosive environments of sea and deserts (Windtrust 2016). Blades made up of composite materials can spin faster and capture winds even at lower speed.
