  • Vertical Axis Wind Turbine Evaluation and Design

    There are two main types of wind turbines. The two general categories for wind turbines include vertical axis or horizontal axis wind turbines. The turbines are classified upon how the shaft of the generator is mounted. The horizontal axis wind turbine HAWT was invented before the vertical axis wind turbine (VAWT), which led to its popularity and

  • Vertical axis wind turbine - Wikipedia

    A vertical axis wind turbine has its axis perpendicular to the wind streamlines and vertical to the ground. A more general term that includes this option is "transverse axis wind turbine" or "cross-flow wind turbine." For example, the original Darrieus patent, US Patent 1835018, includes both options.

  • Vertical-Axis Wind Turbines | Symscape

    A Savonius vertical-axis wind turbine is a slow rotating, high torque machine that is ideal for driving pumps. Whereas most wind turbines use lift generated by airfoil-shaped blades to drive a rotor, the Savonius uses drag and therefore cannot rotate faster than the approaching wind speed.
