| Abstract |
| Wind energy has proven to be an important source of clean and renewable energy. the design of aerodynamic-efficient blade is required not only to improve the performance and reliability of wind turbines, but also to operate these turbines in a safe condition. This project focuses on designing an efficient small-size wind-turbine that can operate efficiently in low wind speed regions as the situation in north Egypt. The design objectives include: cost-effective manufacturing and assembly of the turbine's components, select the size, shape and orientation of rotor blades for maximum induced power, minimize startup friction. In this project, a manually pitch-controlled small-size rotor diameter of wind turbine has been designed, constructed and tested for aerodynamic performance. The present report covers four main tasks. First, careful design of number of flat blades with different size and shapes & make a simulation for each blade on Blade to outline the characteristic of each blade. Second, a pitch control system is to control the pitch angle manually by a moving mechanism implemented to the hub. Third, design the main body of the turbine, & test the numerous blade designs at different pitch angles and record the result of each blade to decide the best pitch angle for each blade and the next stage is to compare the blades with each other to choose the optimal design. Fourth, to enhance the per performance of the turbine is by reducing the friction losses generated due to the ball bearing, so we design a magnetic bearing |
