Vortex-Induced Stall on an Actively Twisted Highly Loaded Model Rotor Blade

Kurzfassung

As preparation for a future wind tunnel test of a rotor with twist actuation blades (STAR II ), a prediction effort by the contributing partners has been executed. In this paper, the results of the planned vortex-induced stall operating condition are presented. The current conclusion is that a noticeable spread of the results is given when searching the maximum attainable thrust, depending on the onset of stall once perceived by the individual simulation methodology. Some general trends for the best suited actuation settings reduce vibrations and required power could still be identified. Generally, most CFD-based results allowed to capture this physical phenomenon, but carefully tuned low-fidelity aerodynamics also managed to capture the same trends at a fraction of the computational cost.
