Vertical Axis Wind Turbines ind ind The Persian windmill was used around 1000 b.c. to turn a grindstone. It is the oldest known windmill design. The machine works by blocking the wind blowing on ½ of its sails. The sails exposed to the wind are pushed downwind due to drag, causing the windmill to rotate. The anonometer is an instrument for

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 wide use. Figure 1.2 shows a diagram of these two types of systems.

Vertical-axis wind turbines were the first structures developed to produce the electricity, paradoxically in contradiction with the traditional windmill with horizontal axis. They have the advantage of having the control members and the generator at the ground level, which make them so easily accessible.

These plans are for the construction of vertical axis wind turbine, modelled after a design by the Finnish engineer S.J. Savonius in 1922. His idea was to mount two half-cylinders on a vertical shaft. It was simple to build, and could accept wind from any direction. However, it was somewhat less efficient than the more common horizontal axis ...

the windmill used to steer it into or out of the wind automatically. Tap - a tool for making thread inside holes so you can fit a screw into the hole. Thrust - The force of the wind pushing the machine backwards. Tower - The mast supporting the windmill. Trailing edge - The blade edge furthest from the leading edge.
