Horizontal Axis Wind Turbinean overview ScienceDirect

The rotor of a horizontal axis wind turbine must always be oriented so that the plane of rotation is perpendicular to the direction of the wind. The can be accomplished either by having the rotor face the wind with the nacelle behind (an upwind design) or with the nacelle facing the wind and the rotor behind (a downwind design).

Aug 07 2017 · So vertical axis wind turbine needs an automatic brake system. As a wind turbine starts to brake it must overcome the rotational inertia and the driving force from the wind. So a good design calculates the torque in the rotor at survival wind speed and chooses a suitable disk brake for that amount of energy. 2. Medium large VAWT technologies

How Do Wind Turbines Work Department of Energy

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades which work like an airplane wing or helicopter rotor blade. When wind flows across the blade the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
