Abstract

This research work is focused on the design and construction of a horizontal wind turbine. This present work is aimed at substantiating the generation of electricity from wind and proffering solution to drawbacks associated with non-renewable energy. The wind turbine is an electric generator moved by the action of the wind. In the first case, the blades represent the change from the wind energy to the mechanical energy. For the second case, the turn of a rotor inside of a generator represents the change from the mechanical energy to electrical energy. The designed and constructed horizontal wind turbine was used to drive a generator to produce electricity by applying the principle of faraday law of electromagnetic induction. The horizontal wind turbine consists of the following major parts; stanchion, yaw mechanism, hub, blade, nacelle, shaft, generator, tail boom, fasteners and Joiners. The results obtained shows that according to Betz’s Law, only 34% of all the mechanical energy developed by the wind will be converted to electrical energy for usage.  The speed of the turbine was obtained as 2182rpm, and rotor speed of the turbine as 228rad/s. The torque effect at the tip speed was obtained as 12.5N/m. It was determined that the maximum stress of the wind turbine blade was in tension (5.69KN/m2), and the minimum stress in compression (3.73KN/m2).
