No load turbine speed
I can't find a definitive answer on the internet so I hope the forum can help.
What would be the approximate shaft RPM of a 2 meter horizontal 3 blade mill in an 8MPH wind with no load, just free rotation? An odd question, but I am putting an idea together to see if it is viable  |

Could be as high as several hundred rpm - depending on bearing friction.

Blade design and pitch is going to dictate the free spinning speed to a point.
It also depends on what style of over-speed protection it has. |

I can bore you with my plan, which may help answer the question. I could do with some input before I expend too much energy or worse, money
