Overview
Wind turbine performance is often characterized by the Tip Speed Ratio (TSR), which is the ratio between the speed of the blade tips and the actual wind speed.
💡
Pro Tips
Tip Speed Ratio (TSR) = (Angular Velocity × Radius) / Wind Speed.
Optimal TSR for 3-blade turbines is usually between 6 and 9.
Too high TSR leads to noise and drag; too low TSR leads to lost energy.

Fun Facts
"The tips of a large turbine can experience centrifugal forces thousands of times greater than gravity."
"Wind turbine blades are typically made of glass-fiber reinforced polyester or epoxy."
"If a turbine rotates too fast, it can literally tear itself apart, which is why they have brakes."
