摘要

Siemens has produced the first batch of 75 m-long B75 rotor blades to be i installed at the second prototype of 1 the company's 6 MW offshore wind turbine. This will be erected towards the end of the year at Denmark's 0sterild test station. The turbine, with a rotor diameter of 154 m, is the largest in the world. At this size, the energy capture area and the turbine capacity have increased by a factor of 200 in the last 30 years. When operating at 10 m/s wind speed, a 154 m rotor extracts energy from 200 t of air per second. The B75 Quantum Blade, as it is called, is designed to provide high strength at a low weight. If it were produced using traditional technology, it would be 25-50 per cent heavier; heavy blades are subject to higher loads and require stronger nacelles, towers, and foundations.
