Wind Turbine Variable Pitch Blade Design Initial Test

This was our first test in our wind tunnel of our design for variable pitch blades. We took this video to document this test and perhaps help us identify points of the blade angle switching. To aid this, we attempted to line the camera up with the edge of the blades so we could see any change in their projected width, as well as our thermo-anemometer so we could tell at what wind speed they changed.
Additional tests will need to be done to characterize this design, hopefully with data logging. It appears that there is some variance in the power output, which could be due to un-damped oscillations caused by the spring.
