eng.wind-turbine-tip-speed-ratio Calculator
Calculates wind turbine tip speed ratio (TSR = blade tip speed / wind speed) and relates it to optimal blade angle and power coefficient. Optimal TSR for 3-blade wind turbines is approximately 7–8 — below-optimal TSR wastes wind energy; above-optimal TSR increases drag losses.
Inputs
V Wind M S
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
N Rpm
Rate of movement. 1 m/s = 3.6 km/h = 2.237 mph.
R M
Distance from centre to edge of a circle. Radius = diameter / 2.
B Blades
Count of items or occurrences.
Results
tip speed ratio TSR
The computed rate of movement or processing.
tip speed (m/s)
The computed rate of movement or processing.
