Wind turbine specialist aerodyn Energiesysteme GmbH (Rendsberg, Germany) reports that it has developed a 111-meter TC1B rotor blade for 11-15 MW wind turbines. To reduce the cost of using carbon fiber, aerodyn says the blade design features hybrid CFRP-GFRP spar caps and can be adjusted according to wind turbine specifications and site conditions.

At a rated power of 14,000 kilowatts, aerodyn’s rotor blade design features a 128-meter rotor diameter with a nominal speed of 7.54 rpm and nominal tip speed of 90 m/s. A 1B design class type, the 14-MW blade maintains a 7.018-meter maximum chord and has 4 meters of prebending at the blade tip. Additionally, the BCD blade root length reaches 5,050 millimeters. 

The company is currently working on 10-MW offshore wind turbines, as well as a future generation of 15-MW systems. For more information, read aerodyne’s technical data sheet
