Vertical-axis wind turbines (VAWTs) come in a wide and interesting variety of physical confi gurations and they involve a range of complex aerodynamic char-acteristics. Not only were VAWTs the fi rst wind turbines to be developed but they have also been built and operated at a scale matching some of the biggest wind turbines ever made.
Classification of Wind-mills ¾Wind turbines are classified into two general types: Horizontal axis and Vertical axis. ¾A horizontal axis machine has its blades rotating on an axis parallel to the ground as shown in the above figure. ¾A vertical axis machine …
The vertical arrangement allows the windmill to be effective regardless of whether it is directed at the wind. It makes the vertical axis windmill the perfect solution in areas where the wind frequently changes direction, since it can harness the wind from any direction. In most cases, the vertical axis windmill has the generator located near ...

A vertical axis turbine (VAWT: Vertical Axis Wind Turbine) functions regardless of the wind direction. The spiral structure of the helix design ensures that even during turbulence, the wind can have an effect on every part of the surface area. The …
Vertical Axis Wind Turbine (VAWT) A wind turbine cannot be a wind turbine unless it has few blades. Likewise, the horizontal axis turbines, vertical axis ones also have a set of blades. But instead of spinning horizontally, they spin vertically. So, the rotational axis of a VAWT is in the vertical direction, and that's why it got such a name.
