  • Design of a vertical-axis wind turbine: how the aspect

    2014-8-2 · There are two types of wind turbine which produce electrical energy from the wind: they are horizontal-axis wind turbines (HAWTs) and vertical-axis wind turbines (VAWTs). The second, and in particular straight-bladed VAWTs, have a simplified geometry with no yaw mechanism or pitch regulation, and have neither twisted nor tapered blades .

  • Eastern Wind Power's Sky Farm ™ 50 kW Vertical Axis

    Why Vertical Axis Wind Turbines. Our focus has been on Vertical Axis Wind Turbines since they have many advantages over horizontal bladed turbines for roof-top as well as for pole mounted applications. VAWTs are quiet, do not harm avian life, do not have
