Mechatronic Design and Fabrication of Aerogenerator composed of Vertical Axis Wind Energy Station with Helical Blades

摘要

An innovative research, supervised by the Research Group of Advanced Robotics and Mechatronics (GI-ROMA) and the Mechatronics Engineering School at Ricardo Palma University, was conducted, which explored the development of a helical vertical axis wind energy station. The mechanical design of the helical vertical axis focused on determining the blade type to achieve a shear stress of τ=5*10<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-10</sup>, nearly negligible, to let a continuous air flow and obtain a desired voltage output of 5 V. The electrical and electronic design included developing a voltage rectification stage to obtain a regulated output of 5 V; subsequently, 6 V 4.5 Ah batteries were charged and connected in series, with a maximum voltage of 12.67 V, as determined experimentally, which was then connected to a voltage inverter which produced 220 V at 200 W, capable of powering appliances like a 5 W light bulb with a 78.50% efficiency.
