Turbine Construction Details

 

Detail description

 

Detail Photo

Each person worked to build a separate part of the turbine. Jarvis and Steve used a rough estimate of size for a blade that I gave them to supply a frame.

Samria used the size I gave her to construct a blade design out of an Arizona iced tea can and some Fome-COR board. Approximate height is 8”.

Jarvis donated a bottom piece to hold a skateboard bearing , for the dowel to fit in.

A hole was drilled in the top of the frame to fit the dowel through, the dowel was sharpened on the end.

I constructed the alternator consisting of the original magnets along with hard drive magnets, which were halved by scoring with a file and pulling apart, which were stacked on top and attached with strong adhesive.

We used the original coils.

I conceived a concept to hold the rotor in place, by drilling a small hole with a 3/32 drill bit through the end of a ¼ in dowel and fitting a  slim finishing nail through.

Turbine Test Procedures

Testing before bringing it to class consisted of simply attaching the 1.5 volt 25 miliAmp LED light to the turbine and checking to see if we were getting any power.  Once in class we tested with a voltage meter, a tachometer and anemometer. Once we used the anemometer, it was obvious the wind speed at which the turbine would turn was rather high. We attached, 100 and 200 ohm loads and tested the voltage with that load resistance as well.

Conclusions

Calculated vs. Measured power of the improved turbine, suggests that there was some mechanical failing preventing us from reaching near our calculated power. I would suggest improving the blade design, before building a larger prototype.  When a larger frame was built along with a larger blade, the compromise was stability.  Also, I’d be interested to use a similar blade design on a horizontal, rather than vertical axis.

 

The most important factors observed in efficient turbine operation were, stability, and the distance between the coils and magnets.
