Experiment Log January 6, min. I followed all procedures and took care while using the fan. Then I used every blade size and shape at the angle of 45 degrees. Post-Experiment Log January 17, min. Change variables and repeat tests 7. Communicate your results Learn more about the scientific method.
What is a wind turbine experiment? We'll begin with the equation that determines how much power you can produce with your wind turbine from awea. In a wind turbine experiment, when you change one variable, remember to keep all other variables constant. Setup You will need to setup a model wind turbine and a fan. You will also need some kind of meter to measure the power output of your data, unless you are using your turbine to do non-electrical work such as weight lifting.
Here are some materials besides a turbine and fan that you may want for the experiment: Tape: for marking a constant spot for your turbine to remain Multimeter: or some kind of meter or load device that will measure the amount of electricity your turbine produces.
Wind Speed Meter: If you want to see how wind speed affects power output, you should use an anemometer to measure the wind speed of your fan. Fans: you should use a floor fan that has at least 3 settings so you can experiment with how wind speed affects power output.I had never built PMA before, but had a real itch to do so. The chip board in the photo caused some problems later. Be sure to scroll all the way down the thread to see photos of these clever designs! I started to science up information on the internet. Wild are three sets of three coils so that each leg of the story has three coils morbid in series. Calculations: If you do any marriage for your project, write your arteries in this hypothesis. The hub should now fit fair the other, and the blades should windmill something readable this.
It has 24 inch blade that are hooked to a hub. The cm2 blades were a too big for the windmill. Once you've established a circle of pennies, use a compass, string and a pencil, or whatever you have that will draw a circle through the center of the pennies.
Red colored plastic red LEDs are hard to see lighting up in daylight. European post-mill whole tower and mechanism turned to face the wind profoundly affected European development from the twelfth to nineteen centuries.
The price is reasonable, and during my tests the performance was good enough to light LEDs under table-fan power. February 7, I finalized my pre-experiment and Experiment log.
These electrons start moving very quickly and move through the copper wire. Fan power may frequently be the only option if the turbine must be demonstrated indoors. But it's well worth it!
The more accurate everything is done the better. The LEDs light very easy without any blades. I think it's a great site for anyone even casually interested in building PMAs , regardless of how they are driven. It will style your machine like a commercial wind generator. The weights can then be screwed to the hub. I finished my journal.

You'll have to choose the size of pipe you use depending on the diameter of the motor you selected; that's why we don't give specific diameters of pipe here.
Once you've established a circle of pennies, use a compass, string and a pencil, or whatever you have that will draw a circle through the center of the pennies. An electric hand drill is used to perforate the center of the wooden block. Our design was very simple -- we ran a 4" long bolt down through the top, fastened underneath the yaw bearing to a pipe cap.

Scientists estimate that some 2 percent of sunlight energy received by the earth is converted to kinetic energy of the winds. I finished a rough draft of my procedures. It is very hard I can not do it at all to light the LEDs by hand spinning the shaft after the blades are attached. Look at pictures of commercial wind generators for good ideas on proportions and lengths. Now is the time to pull together what happened, and assess the experiments you did. Test them by trying to pull them out.
