Thanks to its horizontal-plane rotation and airfoil-shaped blades—borrowed from aircraft wing design—the vertical axis wind turbine operates with ultra-low noise levels, often undetectable under normal environmental conditions. Multiple recording units were placed in line downwind of the turbine to investigate noise propagation. The. . Vertical Axis Wind Turbines (VAWTs) offer a unique approach to wind energy generation compared to their more prevalent horizontal axis counterparts. This configuration concentrates the main stress points around the hub, reducing the risk of blade detachment, fractures, and ejection.
