A vertical axis wind turbine design has vertical alignment of the shaft. One of the major benefits of such turbines is that there is no need for the turbine to be positioned into the wind to be efficient. These wind turbines are as a rule used on locations that witness a fluctuating wind direction. Wind energy from all positions can be utilized by vertical axis wind turbines (VAWT). This picture seems not be a vertical axis construction but a nice small scale wind power system.
Vertical axis means that the gearbox and also the generator can be located close by ground as there is no need for the tower to offer it support. This also means that the gearbox and the generator are at hand when you need to maintain the wind turbines. This type of wind turbine design is not what you should think about if you are about to build wind generator.
Wind Turbines – Design
The wind turbines have to take advantage of the wind energy present at a distinct position. Designers and constructors use the aerodynamic modeling for the conclusion of the different control systems to be used, number of blades, models of the blade, and the most favorable height of the tower.
The new wind turbines are primarily build for transformation of wind energy into electricity. In accordance with this purpose, the wind turbine has three major components, namely the rotor component, the generator component, and the structural component. About 20% of the cost of the wind turbine is taken up by the rotor, while an approximate 34% of the cost is spend by the generator. 15% of the cost of the wind turbine is taken up the structural components. These figures might be a bit different today.
