Abstract

The TAU-HOST coupling chain for Fluid-Structure Interaction (FSI) simulations of active helicopter-rotors is validated by computing the HART II experiment. The result accuracy of the unstructured flow solver TAU is investigated in the case of a rotor which experiences Higher Harmonic Controls (HHC). Investigations are performed by a code-to-code comparison with the experiment, FLOWer-HOST, and literature. Moreover, a time-step study and mesh refinement study were performed but improvement of Blade-Vortex Interaction (BVI) intensity fell short of expectations. Nevertheless, results of rotor controls, blade loads and blade deformation show good agreement with experimental data and are in accordance with literature.
