How do these types of wind turbines maintain their face into the wind? No vertical stabilizer?
I've seen a lot of them lately turned away from the wind, just doing nothing. Why no tails?
It seems that if the wind blew on a 3blade arrangement, it would always want to turn in the direction of the two blade side and it would just swivel off the wind. If it managed to get going, the 2bladed side would change with 1/2 revolution and then it would want to swivel off to the other side. Do they simply swivel a little bit in one direction, then the other at half rev, then the other at a full rev? Seems like a little bit of a tail would help greatly with that. Surely the wind on the nacelle isn't going to be enough to keep them facing the wind. That doesn't look like much of a tail. Is it enough (at least in most case) to keep them heading into the wind?
