The aerodynamic and noise analysis were performed through the CFD-CSD loose coupling methodology. In the loose coupling process, the trimmed rotor airloads were predicted by the in-house CFD code based on an unstructured overset meshes, and the trim of the rotorcraft and the aeroelastic deformation of the rotor blades were accounted with the CAMRAD II rotorcraft comprehensive code. The set of codes was used to analyze the HART-II baseline test condition. The effect of grid resolution and time step was examined and the loose coupling approach was found to be stable and convergent for the case. Comparison of the resulting sectional airloads, structural deformations and the noise carpets with experimentally measured data was presented and showed the good agreement.
