Technical FAQs 4

What are the two types of vertical axis wind turbines?

The two types of vertical-axis wind turbines are the Darrieus wind turbine, which turns a shaft using lift forces, and the Savonius wind turbine, whose cups are pushed by direct wind forces. Vertical-axis wind turbines can produce electrical power at lower speeds and at a variety of changing speeds.

Why is vertical axis wind turbine design important?

Modern vertical axis wind turbine design is advancing rapidly, thanks to improved structural layouts, material science, and control systems. Despite some limitations, vertical axis turbines offer compelling advantages: low noise, omni-directional wind capture, strong wind resistance, and lower maintenance needs.

What is a vertical axis wind turbine (VAWT)?

Vertical axis wind turbines (VAWTs) provide distinct advantages in specific environments and use cases that are not always practical for traditional horizontal axis designs.

How does a Savonius vertical axis wind turbine work?

The Savonius vertical-axis wind turbine uses cups, called scoops, instead of blades to capture wind power. Figure 5 shows an example of a Savonius vertical-axis wind turbine. When the wind blows, it creates a positive force in the scoop and a negative force on the back side of the scoop. This difference in force pushes the turbine around.
