Wind Turbine Blade Pitch Electricity Science Fair Projects

PURPOSE

The first purpose of this experiment was to determine which degree of turbine blade pitch produced the most electricity.

I became interested in this idea when I saw wind turbines on a hill. I wondered if a different degree of turbine blade pitch would produce more electricity.

The information gained from this experiment would help society by coming up with a more efficient way of producing electricity from a non-polluting source.

This also makes a great project for classrooms, science camps and groups. Check out the discount prices.

HYPOTHESIS

My hypothesis was that the 60º of pitch would produce the most electricity.

My second hypothesis was that the 20º of pitch would produce the least amount of electricity.

EXPERIMENT DESIGN

The constants in this study were:

• The tower structure.
•  The height of the tower.
•  The width of the tower.
•  The materials used to create the tower.
• The amount of wind.
• The type of shop-vac.
• The distance of the leaf blower from the wind turbine.
• The type of wood used to create the blades.
• The amount of wood I started out with to make each blade.
• The materials used to create the blades.
• The length of the blades.
• The place I conduct the experiment.
• The thickness of blades.

The manipulated variable was the angle of pitch of the turbine blade.

The responding variable was the electrical output.

To measure the responding variable I used a millivolt-meter.
