1. Wind Turbine Lab (Part B)
ENGR 1181

2. Wind Turbine
Wind power industry using wind turbines is clean with a fast growth in technology and demand.
Rotor is the main component in capturing wind’s energy.

3. Today's Learning Objectives
After today's class, students will be able to:
Describe the effect of various parameters on generated power, including wind turbine blade design, number of blades, and pitch angle

4. Propeller Pitch
In addition to the shape of the air foil, the pitch of the propellers impacts the efficiency of the turbine.
In the lab you will be using these two hubs to hold your propellers. They look similar, so be careful!
30° Pitch
45° Pitch

Wind Turbine Lab Setup

6. Tips for a Successful Lab
Make sure to correctly connect wind turbine to the Arduino board, check the results
If the hub is loose and slips, ask a member of the teaching staff for a replacement
One blade may produce less than 1mW power
Be careful when cutting the balsawood!
Do not forget to clean-up after the lab

7. Important Takeaways
There are many, many possibilities of designs for air foils.
Several factors influence the performance and efficiency of a wind turbine.
