wind turbine blades,twin bladed rotor. frame for futurenergy pmg & rotor éolienne

High area/ 1.8 metre diameter rotor with high rpm / power capability mounted on a futurenergy pmg & my chassis . A 3 blade using same shape with 50% more area is used on a modified Bosch alternator, see website at bottom, It's little realized but twin bladed designs generally have higher tsr capability than the common 'danish' 3 bladed system, 20-30kw twin blade are in production & use now and work very well,like down wind Italian giai turbines, some have been in constant use for 15+ years, many twin bladers are in constant service in Holland also.

Yes some but only at very high rpm, when most turbines would have furled, for best outputs a good twin blade is very hard to beat though. My tri blade uses the same basic proven shape, but modified angles, they are very smooth and fast running awell. Dave.

So did you have any vibration problems (twin blades are supposed to cause problems due to the see-saw effect).
