This is a bit different from the wind turbines we have near EDLN (Cologne area). If the wind is too high they feather their blades but still are being turned to face the wind - I think this is being required by the layout of the hub structure. When the wind is 'right' they rotate at a speed that is depending on the wind speed. The conversion into alternating current of a fixed frequency is being done electronically already for a looong time. I think this applies to almost all German and Dutch wind turbines that _I_ have ever seen (and I'm already in the mid-thirties) - not that I claim to have seen all wind turbines in our country .... :-) Martin. -- Unix _IS_ user friendly - it's just selective about who its friends are ! -------------------------------------------------------------------------- _______________________________________________ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
