The students learn to combine the small-scale effects of rotor aerodynamics with the large-scale interactions of the complex aeroelastic system and to understand both system-specific and component-specific effects. They learn the fundamentals of rotor aerodynamics and are able to perform a simple analysis or design of a rotor. The methods learned are extended for aeroelastic calculations of modern multi-megawatt class systems. The goal is a deep understanding of the complex, three-dimensional and transient flow processes on the rotor and the fluid-structure interactions in modern wind turbines.
