At what angle should the blades of a wind turbine be positioned? Featured science projectScience project video


The results show that increasing the angle of which the  wind turbine blades are positioned up to 75° will increase the output voltage. Beyond 75° the output voltage will decrease .

Blade Angle 15° 30° 45° 60° 75° 95°
DV Volts produced 0 0.15 0.45 0.6 0.85 0.95 0
