Wind Turbine Blade Efficiency and Power ... - IJSRP

Ratio (TSR) which is defined as : TIP SPEED RATIO (TSR) = (tip speed of lade)/(wind speed). The tip speed ratio is a very important factor in the different formulas of blade design. Generally can be said, that slow running multi bladed wind turbine rotors operate with tip speed ratios like 1-4, while fast runners use 5-7 as tip speed ratios.
