Exploring Wind Turbine Blades

Figure from experiment 5 from Investigating Wind Energy


Blade design and engineering is one of the most complicated and important aspects of wind turbine technology. The blades of a wind turbine are the parts of the turbine that catch the wind. This causes the turbine to spin, which causes the generator to generate electricity. If the blades do not move, the wind turbine cannot generate electricity.

Blade design engineers try to design blades that efficiently capture wind energy. They also need to design blades that are durable, quiet, and affordable.

In this experiment, you will explore how blades interact with the wind and make the turbine spin. You will use data-collection equipment to measure the output of the wind turbine to determine how blade orientation affects the flow of electrons in a circuit. This information will allow you to set up your turbine correctly as you explore more advanced blade design in other experiments.


  • Explore how the orientation of a blade affects the direction in which the wind turbine spins.
  • Measure current and potential difference (voltage) output of a wind turbine with a Vernier Energy Sensor.
  • Explore how orientation of a blade affects the sign of the current and potential difference values.
