Why do some wind turbines move so slowly?



  1. 0 Votes

    The blades of wind turbines are designed to move at variable speeds depending on how fast the wind is blowing. In low winds, turbines (like pinwheels) don’t move quite as fast. The rate at which the blades move relative to the speed of the wind is called “tip speed ratio.” The higher the tip speed ratio, the faster the turbines. An ideal tip speed ratio is about 6, which means that the tips of the blades move 6 times faster than the wind. Most wind turbines have lower tip speed ratios. A higher tip speed ratio would cause the turbine to become unstable.
