Windmills
What windmill design will generate the greatest rotational speed?
In this exhibit the challenge is to design a windmill that will spin very fast. Choose a blade shape, the number of blades, and the position the blades will face in the propeller (angle of attack). The rotation of the windmill can be used to power a small electrical generator so once you have your design ready, hook it up and try it out in the wind tunnel. You can measure the success of your design by the level of electrical output that you create. Make some changes and test the "power" of your new design.
