The focus of this study is to observe the effects of friction over the wind turbine blades and how the output of the wind turbine can be improved. In this study, the factor of frictional forces exerted over a wind turbine blade is used to obtain the correct values of chord and twist to enhance the overall output of the wind turbine. A preliminary blade consisting of 4 different NACA airfoils is designed using the Glauert method and simulated to obtain the baseline data. The obtained chord lengths and twist angles are set as input parameters, whereas frictional forces acting are set as objective outcome parameters for the optimization using the single objective optimization method. Scatter plots and Pareto fronts are being used to determine the optimum candidate chord and twist for the optimized blade geometry. The design of the domain is mostly reduced, and only 05 points along the blade chord are selected to find global optimum results due to computational limitations. The wind velocities of 08 m/s, 10 m/s, 12 m/s, 14 m/s, and 16 m/s are used to compare the results of both the preliminary blade model and the optimized blade model and also to present the flow and pressure visualization. The widely recognized and commercially available ANSYS is used for the simulation purposes Structure: introduction, literature review, methodology, results and discussion, conclusion and recommendations, references

A mechanical mounting structure was designed, and the shafts, bearings, drives, and stepper motors were selected. The structural strength of the system was evaluated using 鈥淪olidWorks Simulation鈥� software. In addition, assembly process planning, assembly time calculations, and production line balancing using different methods were carried out. The thesis also includes an economic analysis, manufacturing cost calculations, and break-even point determination.
