What is the wind turbine vertical?

, which is usually built only with two or three blades, is a wind turbine (VAWT) vertical axis (VAWT) with a type of wind turbine, in which the main rotor shaft runs more vertically than horizontally. Although there are different styles of these types of turbines, one version looks like an egg engraving. On the other hand, his movement is similar to spinning the coin on the edge.

When most people hear the sentence "wind turbine", they visualize the horizontal wind turbine (Hawt). Hawt looks very similar to the propeller aircraft. The reason why people closely associate Hawt with the concept of wind turbines is simply because the wind turbine vertical axis is not as common as its horizontal counterpart. In fact, VAWTS is generally not used for commercial purposes and are rarely connected to electricity networks.

Of course, despite their differences in the appearance and their different traffic modes, both Vawt and Hawt create electricity by converting wind energy filming torque using a rotating shaft. It means thatE wind turns the wind turbine blades around the turbine rotor. This rotor is connected to the main turbine shaft and that the main shaft is powered by a generator that produces electricity.

In the design of the vertical wind turbine axis, certain advantages are connected. The generator and turbine gearbox can be placed close to the ground level, making it easier to maintain and reduce the initial construction costs. Also, they do not have to face the wind like Hawts, which increases their ability to use wind strength and thus increases their overall reliability. Manufacturers also claim that Vawt is less noisy than his Hawt counterpart.

However, the primary disadvantage associated with a vertical wind turbine is that its efficiency is reduced because wind speeds are lower near the ground. This type of turbine is General You can produce as much electricity as the Hawt design. Vawts also do not care, an obstacle to the grid power connection. For these reasons it is for the instalor often selected wind turbine vertical axis when the main problem is of cost or reliability. If the most important aspects of overall performance and efficiency are usually used by the wind turbine horizontal axis.

Research is carried out on Vawts in an effort to increase their energy performance and minimize their mechanical and aerodynamic noise. Engineers hope that this type of wind turbine is improved so that it can eventually be widely used in urban landscapes, where the space for installing wind farms is limited.

of many types of vertical types of wind turbines, two most commonly designed are Savonious and Darrieus turbines. A Finnish engineer named Sigurd J. Savonius invented a simple turbine type of campaign and French engineer Georges Jean Marie Darrieus was inventing a more practical lift turbine in 1927. Cycling.
