In order to lay the technical foundation for the development of 11-15 MW wind turbines, Germany aerodyn company has initially designed a 14MW wind turbine, and will use 111m long TC1B wind turbine blades. The main beam of the blade is made of carbon fiber-glass fiber mixed reinforced composite material, which reduces the cost of carbon fiber to a minimum.
Modern structural design concepts, plus aerodyn's more than 30 years of fan blade development experience, have created TC1B fan blades suitable for 14 MW fans. The blade can be adjusted and optimized according to specific conditions such as rated power, fan type, wind farm environment and so on. The development process uses the most advanced materials and manufacturing technologies.
At a rated power of 14 MW, aerodyn's fan blades can achieve an impeller diameter of 228 m, a rated speed of 7.54 rpm, and a rated tip speed of 90 m/s. At the same time, the blade maintains a maximum chord length of 7.018 m, and the blade tip is pre-bent by 4 m. In addition, the blade root bolt circle diameter (root pitch circle diameter) reaches 5050 mm.
At present, the company's work is focused on the development of 10 MW wind turbines, which will be put into production next year. In the next step, larger power wind turbines (such as 15 MW) will be available in the market by 2025, and the supply chain and necessary infrastructure are great challenges in implementing future plans.
