The construction of rotor blades for large wind turbines presents a specific challenge. On the one hand, the turbines should have a high energy yield, and on the other, they need to be inexpensive to manufacture, and require as little maintenance as possible over a planned lifecycle of up to 20 years.
Leichtwerk AG uses integrated solution approaches for the development of rotor blades by combining aerodynamic and structural design processes. Nowadays, reliability and sustainability are decisive for the economic efficiency of such modern plants, particularly in offshore projects. Leichtwerk AG works consistently on the development of methods for the qualification of sustainable materials like bondings and non-crimp fabrics. To this end, as well as for the development of new structures, the company uses the available fracture mechanic theories.
