Lenz2 Style VAWT Test

A brief test of a small VAWT modeled after the popular DIY "Lenz2" design. However, instead of having a circular leading edge and straight sides like a Newman Circular Nose airfoil, this one uses an NPL EC airfoil that has an elliptical leading edge and cubic sides. In keeping with the Lenz2 design, the solidity is 1.0 which is higher than my previous models, and the airfoil has a thickness of 46% which is high compared to the others. Also the trailing edge is rotated inward 15 degrees about the mid-chord point as with the Lenz2. I also curved the airfoil around the circular path that wing travels. I don't know if that is a good thing or not, but it seemed to make sense to me. The result is a turbine that starts turning in a light wind and seems to increase speed smoothly as the wind speed increases. I don't know yet if the RPM will be high enough to light an LED, but it looks promising.
