MORE ON WIND POWERED DEVICES

V. Ryan 2006 - 2009

 

Another example of a wind powered device is seen below. A simple crank mechanism seen in the centre of the animation is the key mechanism. (click here for more on mechanisms including cranks)

   
   
 
   

As the propeller revolves the crank mechanism is pushed round. The speed of the wind determines the revolutions per minute (RPM) of the crank.
   

A small, lightweight model can be attached/fixed to the top of the crank mechanism. As the crank revolves the model moves from side to side in a relatively smooth action.
