  • Vertical axis wind turbine technology continues to improve

    07/08/2017  1.3 How to design a good small vertical-axis wind turbine. 1.3.1 Although different from a HAWT, the core technology of a VAWT remains a wind mill structure with blades. After choosing an airfoil, it is necessary to calculate a concave orientation, angle, width, and quantity because each of these factors determines the performance of the VAWT. So a first step is to choose a low-speed airfoil ...

    A vertical-axis wind turbines (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind (but not necessarily vertically) while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair. VAWTs do not need to be pointed into the wind, which removes the need for wind-sensing and orientation mechanisms. Major drawbacks for the early designs (Savonius, Darrieus and gir

    vertical axis turbines do not care from which way the wind blows so if the wind changes direction the turbine is still producing at 100% of what it can produce at that wind speed. there is no loss in efficiency. with a propeller turbine if the wind changes direction it'll only be producing at a fraction of what it could until it can orient itself. I'm sure that turbine designers have a term ...

    31/10/2014  Efficiency – When the wind blows on the blades of a HAWT, all of them contribute to energy production. When wind blows on a vertical-axis turbine, only a fraction of the blades generate torque while the other parts merely ‘go along for the ride’. The result is comparably reduced efficiency in power generation.
