  • The Tip Speed Ratio (TSR) is an extremely important factor in wind turbine design.
  • ​​Tip speed ratio = \(Tip\; speed \: of \: blade \over Wind \: speed\)
  • The Tip Speed Ratio (TSR) is used by wind turbine designers to properly match and optimize a blade set to a particular generator
  • : Blade speed ratio or flow ratio (ρ): It is the ratio of blade speed to the tangential component of jet speed of a turbine.
