These exercises are partially held in English and partially in German.
The students can classify and describe the various wind turbine types and their aerodynamic characteristics. They are also capable of solving or programming the blade element method, and to use the method to relate the energy balances to the flow physics. Using the wind turbine design software QBlade, the students can quantify the aerodynamic performance and the power output of any rotor design. From the structural part, the students know the various designs of modern rotor blades. They are familiar with typical load cases resulting from several sources. They can analyze typical damages which may occur in composite rotor blades, both in composite and sandwich structures. Furthermore, they are able to use classical ways of mechanical analysis with respect to stiffness and strength including the usage of codes like eLamX.
