Question

why three blade wind turbine is costlier than single and two bladed wind turbine

Answer 1

three blade wind turbines are most costlier than single or two blade wind turbines because if blades are more than turbine will move easily so it will be more costliee

Answer 2

S O L U T I O N :

• With three blades, the angular momentum stays constant because when one blade is up, the other two are pointing at an angle.

• So the turbine can rotate into the wind smoothly.
