Testing the wind turbines:
- Use the same electrical circuit as you did when testing on the battery. The optimal load is \( R_{out} = 100 \Omega \)
- Data collection
- The currents are not so high so you can use Pasco sensors for both current and voltage.
- You'll need one 'user entered data' coloumn for the tested parameter
- Use manual data collection
- Sample data for voltage and current for each change of parameter
- Data handling / calculations
- In each case calculate the power output from the turbine
- Plot a graph showing the parameter changing on the x-axis and the power output on the y-axis
When testing the impact of one parameter on the power output, you will have to make sure, that you test under simular conditions, that is keeping everything else but constant
Parameters to test:
- Speed of the wind
- Meassure the speed of the wind with an anemometer (wind speed sensor) at different settings of the fan (1,2,3) in different distances from the fan. Make markings on the paper to show the speed of the wind in the different positions.
- Shape of the wings
- Number of wings
- You'll have to borrow wings from an other group to have the same shape for all your wings
- Pitch on the wings (the angle of attack the wing relativ to the direction of the wind)
- Direction of the wind relativ to the turbine
- ??
When all of the above have been tested, join in with some of the other groups to test the power yield when the turbines are placed in a cluster. Find out the best positions for the turbines relative to each other for the highest yield.
