WELCOME TO VERTOGEN LTD - Vertical Wind Turbines

Hi, Just keeping you updated on our progress. Recent work has refined the performance within normal working conditions. To dynamically monitor the variable pitch system, we designed and installed wireless hardware to a turbine blade to monitor VAWT blade pitch, RPM, Voltage, Watts, Generator RPM, Wind Speed, Wind Direction and full weather conditions.

Vertical Axis Wind Turbine: All You Wanted to Know

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.

The horizontal axis windmills primarily rely on lift from the wind. As stated in Bernoulli's Principle, "a fluid will travel from an area of higher pressure to an area of lower pressure.". It also states, "as the velocity of a fluid increases, its density decreases.". Based upon this principle, horizontal axis windmill blades have ...

Vertical Axis Wind Turbine - an overview - ScienceDirect

Vertical axis wind turbines (or VAWTs) have the main rotor shaft arranged vertically. Key advantages of this arrangement are that the turbine does not need to be pointed into the wind to be effective. This is an advantage on sites where the wind direction is highly variable. VAWTs can utilise winds from varying directions.

Types of Wind Turbine: Horizontal and Vertical Axis Wind ...

In a vertical axis wind turbine, the blades are aerofoil shape and it can take the wind from any directions. The rotor is not self-starting. The rotor is supported by a system of guy cables. The base of the wind turbine rotor is coupled to a generator by a drive flexible coupling. Here the blades rotate around a vertical axis.

Vertical-axis wind turbines: what makes them better ...

For instance: Efficiency – When the wind blows on the blades of a HAWT, all of them contribute to energy production. When wind blows on a vertical-axis turbine, only a fraction of the blades generate torque while the other parts merely 'go along for the ride'. The result is comparably reduced efficiency in power generation.

• Vertical Axis Wind Turbines (VAWT): the rotational axis is perpendicular to the wind direction or the mounting surface. The main advantage is that the generator is on ground level so they are more accessible and they don't need a yaw system. Because of its proximity to ground, wind speeds available are lower. 12
