A wind turbine rotates to face into the wind. The blades pick up the wind and feed into a low-speed shaft which runs at the same speed as the blades (7 to 12 revolutions per minute).

Using this technique, Tyagi rewrote Glauert’s original solution. Plus, it allowed Tyagi to extend that solution to more complicated scenarios. In particular, Tyagi included the effects of the air wind ...
