Vertical Axis Wind Turbine Blades. The blades on modern turbines catch the wind and use it to rotate the shaft of a generator. The spinning shaft of the generator converts mechanical energy into electricity. The blades of a wind turbine have the most important job of any wind turbine; How well you design your blades can greatly impact how much power your turbine produces.

Design and Construction of Vertical Axis Wind Turbine

Wind turbines are classified into horizontal axis wind turbine (HAWT) and vertical axis wind turbine (VAWT). The main difference between these two is the orientation of the rotational axis. The advantage of having a vertical axis wind turbine of rotation is that it can absorb wind in all direction without the need for yaw mechanism.
