OK, I found this for a NJ wind farm.

Quote:

Depending on wind conditions the blades turn at rates between 10 and 20 revolutions per minute. Considering the length of the blades, at average wind speeds of 13 to 15 mph, the tips are traveling at 120 mph. At maximum wind speeds, the blade tips are spinning at an estimated 180 mph.

Reminds me of the Chinook blades spinning at 102 rpm, with a tip speed of near 500 mph.
