Structural Development and Optimization of Wind Power Plants Rotor Blades

Dr. Christoph Katzenschwanz, ACENTISS GmbH

Various engineering disciplines designing wind turbines can be supported by engineering expertise derived from aerospace design activities. This presentation compares the system requirements in the aerospace and wind-energy sectors, addressing requirements from the airlines, aircraft suppliers and significant loadcases for aircraft. Those specifications are discussed in comparison with requirements on wind-energy installations and design-determining factors. Design development processes, materials and manufacturing processes are also presented focusing on the transferability from aerospace application to wind energy converters. Under this context, the numerical results derived from the structural development of rotor blades in the scope of optimization procedures are presented. Aiming for high energy wind turbine plants a specifically developed rotor blade with segmented layout is discussed.
