Design and Analysis of 5 kW wind Turbine Blade for Rural and Remote Areas Institutions in Ethiopia: Case of Degua Warren Kebele

Halefom Kidane, Gebremeskel Tekle

Small wind turbine has great role in rural and remote areas in which the electric accesses from the grid is difficult. In this paper, horizontal axis wind turbine blade which has capacity of 5 kW was designed and verified with the help of the blade element momentum theory. Using this theory, the twist angle and chord length for each section the mid radius and the local tip speed ratio blade were calculated. Lift force is the main force for operating the wind turbine to produce useful power. Thus, Maximum lift-to-drag ratio is criterion for choosing the air foil family. Here SG air foil family were selected because they specifically designed for small wind turbine.
