The wind turbine blades turn a circle
The blades multiply the wind’s force like a wheel and axle, so a breeze is often enough to make the blades turn around.
The blades multiply the wind’s force like a wheel and axle, so a breeze is often enough to make the blades turn around.
The majority of wind turbines have a horizontal axis: a propeller-style design with blades that rotate around a horizontal axis.
As wind forces the blade to flex, twisting changes the blade’s angle of attack (the angle at which the blade meets the wind), and thus reduces the load on the blade, decreases stress, and allows fo.
Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity. To see how a wind turbine works, click on the image for a demonstration.
