Primary 5 – 7 have linked up with the Glasgow Science Centre to take part in a Renewable Energy project.
Today, we constructed model wind turbines and experimented with different blade designs, some flat and some with folds.
We then tested our models and found that putting a fold into the blade made the blades turn much more easily. Have a look at Lewis demonstrating the efficiency of the flat blade first. He then placed a fold in his blades. Look at the difference in how the blades rotate!
Conclusion by Lewis:
The wind turbine blades with a fold has more drag which causes it to catch the wind current. It has a higher, more efficient rotation rate than the blades that are flat. That means the folded blades will go faster than the ones without flaps.
