| dc.description.abstract | Designing small scale horizontal-axis wind turbine (HAWT) blade to achieve satisfactory levels of performance starts with knowledge of the aerodynamic forces acting on the blade. In this thesis Blade-element momentum theory (BEM) known as also strip theory, which is the current mainstay of aerodynamic design and analysis of HAWT blade, is used for HAWT blade design. The blade design program includes blade geometry parameters (chord-length and twist distributions) and design conditions (design tip-speed ratio, design power coefficient and rotor diameter) with the following inputs; power required from a turbine, number of blades, environmental wind velocity at Negele Borana and blade profile type (airfoil type). This thesis, focused on the design and stress analysis of small scale wind turbine blade which built for the specific environmental conditions of the small rural village for Laga-Gula kebele communities at Negele Borana. First the blade designed from the aspect of aerodynamic view and the basic principles of the aerodynamic behaviors of HAWT studied. Second modeling and stress analysis of the wind turbine blade are very critically for the further design and application of wind turbine. The small-scale wind turbine blade was focused on, considering the E-Glass fiber reinforced plastic material. Based on the parameters of airfoil and the geometrical parameters of blade, the three-dimension and the assembly models of blades were established with the SOLIDWORK modeling software. Then the models were imported into ANSYS-15 WORKBEANCH software analysis. The displacement, Von Misses and principal stress results are determined. These results show that the positions of maximal displacement and maximum stresses, but it is less than the safety displacement and Ultimate tensile strength (UTS) of the xv material, and also it shows the environmental wind speed can produced the sufficient power for Laga-Gula rural kebele communities. | en_US |
