Aeroelastic Optimization of MW Wind Turbines

This report contains the results from the Energy Development and Demonstration Project “Aeroelastic Optimization of MW wind turbine” (AeroOpt). The project has had the following five Work Packages: 1. Geometric non-linear, anisotropic beam element for HAWC2 2. Closed-loop eigenvalue analysis of controlled wind turb ines 3. Resonant wave excitation of lateral tower bending modes 4. Development of next generation aerodynamic design tools 5. Advanced design and verification of airfoils The purposes of these Work Packages are briefly described in the Preface and a summary of the results are given in Section 2 . Thereafter, the results from each Work Package are describe d in eight subsequent chapters.
