摘要

There is a growing need to utilize alternative energy sources to achieve sustainable development goals and address the challenges posed by climate change. Wind turbines are widely used for large-scale power generation, with commercial systems capable of producing up to 3 MW of electricity. However, there is also a demand for small-scale wind energy systems capable of generating approximately 1 kW of power for residential applications. This research focuses on the design, analysis, and development of wind turbine blades specifically intended for small-scale power generation in residential areas. To enhance the mechanical performance and durability of the blades, Polyethylene Terephthalate Glycol (PETG) and Carbon Fiber (CF)-reinforced PETG composite materials were selected. These materials were rigorously evaluated through mechanical testing, including tensile and bending tests, to assess their suitability and reliability for wind turbine applications. The blade design was developed by considering the aerodynamic forces acting on the blade to maximize power generation efficiency. Autodesk Inventor 2024 was used to model the blade geometry, while ANSYS Workbench R20 was employed to analyze its aerodynamic performance under various operating conditions. The simulation results were compared with theoretical calculations to validate the accuracy of the design. Finally, the optimized wind turbine blade was successfully fabricated using 3D printing technology.
