Abstract
Coupled fluid-structure simulations of high fidelity tools have the potential to deliver a more accurate prediction of the aerodynamic and structural properties of helicopters in forward flight than comprehensive rotor codes. Within this paper the aeroelastic behavior of a trimmed helicopter rotor was investigated using strong and loose coupling approaches. Results of the coupling chains HOST-TAU and SIMPACK-TAU are compared to experimental data from the European GOAHEAD test campaign. The validation test case is a cruise flight condition at Ma \(=\) 0.204 related to an advance ratio of \(\mu = 0.33\). Pressure distributions along the blade and blade deflections are in good agreement with experimental results and among the coupling approaches.
