Optimal tip speed ratio

WebThe optimal tip speed ratio depends on the number of rotor blades n of the wind turbine. The smaller the number of blades, the faster the wind turbine has to rotate to extract … WebAn optimal tip speed ratio depends on many things, but for 3-blade turbines it’s somewhere between 5-9 depending on the turbine design. That means for a turbine with an optimal tip speed ratio of 9, where the wind blows at 10 m/s, the tips of the turbines must move at a staggering 90 m/s to achieve optimal tip speed ratio.
