Description: Das Projekt "Advanced Aerodynamic Tools for large Rotors (AVATAR)" wird vom Umweltbundesamt gefördert und von Energy Research Centre of the Netherlands durchgeführt. The motivation for the AVATAR project lies in the fact that up-scaling wind turbines towards 10-20 MW is expected to lead to radical innovations and design challenges in order to make such turbines feasible and cost effective. Many of these innovations (i.e. design philosophies leading to slender blades with tailored aeroelastic characteristics, thick airfoils, high tip speeds and the use of distributed flow control devices) have a strong aerodynamic component and can be considered as unconventional from an aero-elastic point of view: they violate assumptions in current tools on e.g. compressibility and Reynolds number effects, as well as assumptions on flow transition and separation effects, all in combination with a much more complex flow-structure interaction. Hence the analysis of these up-scaled rotor designs falls outside the validated range of applicability of the current state of the art computational aeroelastic tools. AVATAR will therefore bring the aerodynamic and aeroelastic models to a next level and calibrate them for all relevant aspects which are expected to play a role at large (10MW+) wind turbines.
