LM Glasfiber's 61.5m blade
The massive blad features a rotor diameter of 126m, and three blades on a turbine cover an area almost the size of two football fields.
A 61.5m/201.7-ft wind blade â€“ the longest on the market today â€“ has earned LM Glasfiber (Lunderskov, Denmark) a spot among the five finalists for The Confederation of Danish Industry's Product Prize 2007.
The 61.5m blade design features a rotor diameter of 126m, and the three blades on a turbine cover an area almost the size of two football fields. This is the largest, longest blade in operation, and its cost is optimized through light, stiff and large blades. From this area the blades are capable of capturing energy from the wind corresponding to a nominal effect of 5 MW, or the annual power consumption of about 5,000 households.
