Brief Introduction To The Darrieus Wind Turbines

Darrieus wind turbine explained.The darrieus wind turbine is a type of vertical axis wind turbine (vawt) used to generate electricity from the energy carried in the wind.The turbine consists of a number of curved aerofoil blades mounted on a rotating shaft or framework.The curvature of the blades allows the blade to be stressed only in tension at high rotating speeds.

  • Darrieuswindturbine Definition Of Darrieuswind

    The blades of a darrieus turbine can be canted into a helix, e.G.Three blades and a helical twist of 60 degrees, similar to gorlov's water turbines.Since the wind pulls each blade around on both the windward and leeward sides of the turbine, this feature spreads the torque evenly over the entire revolution, thus preventing destructive pulsations.
