6.3.2 Vertical axis wind turbines (VAWTs) A vertical axis wind turbine (VAWT) is a type of wind turbine in which the axis of rotation of the rotor is perpendicular to the wind direction. The gearbox and generator are positioned at the base of the turbine, which makes maintenance easy.

Windmills and Their Technology since the Middle Ages

The first practical windmills were panemone windmills, using sails that rotated in a horizontal plane, around a vertical axis. Made of six to 12 sails covered in reed matting or cloth material, these windmills were used to grind grain or draw up water. [9] These windmills are recorded by Persian geographer Estakhri in the 9th century as …

Vertical Axis Wind Turbines

The Darrieus rotor is a type of vertical axis wind turbine (VAWT) known for its distinctive eggbeater shape. It consists of curved airfoil blades that are arranged in a vertical orientation around the central axis. Darrieus rotors are named after Georges Jean Marie Darrieus, a French engineer who patented the design in 1926.
