Wind Control Vertical Axis Wind Turbine
Compared to horizontal turbines, vertical axis wind turbines can achieve higher rotational speeds and maintain stability in stronger winds—up to 60 m/s. This configuration concentrates the main stress points around the hub, reducing the risk of blade detachment, fractures, and ejection. Several fixed and variable blade pitch models under different tip speed ratio are adopted to improve performance of the wind turbine.
