The World’s Largest Wind Turbine Blade


Siemens has built a record breaking rotor; in more ways than one. Not only have they constructed the world’s largest rotor blade for wind turbines, but it is also the world’s largest fiberglass component to ever be cast in one piece. The giant, 75 meter (246 ft) long rotor blades will be installed in an offshore prototype wind turbine in Denmark later this year (2012). Called the Quantum Blade B75, this rotor is almost the length of an Airbus A380.

Record-Breaking rotor: World’s largest rotor blade
With a length of 75 meters, Siemens has built the world’s largest rotor blades for wind turbines. The giant components made of fiber glass will be used by Siemens’ new offshore wind turbine generation with a capacity of 6 megawatts (MW). They will be installed on the first prototype of Siemens’ 6-MW offshore wind turbine with the 154-meter-rotor, which will be erected this summer in Denmark’s Østerild. Each rotor has a diameter of 154 meters covering 18,600 square meters, which is the size of two and a half soccer fields. The tips of the blades move at up to 80 meters per second, or 290 kilometers per hour. The huge rotor was made possible by special technologies that enable Siemens to make extremely strong yet lightweight structures.
