The present report summarizes the part II of the activity performed in the framework of the "VITAS-OR4" Project funded by Piaggio Aero Industries SpA. In details, the aerodynamic analysis of "Piaggio P180" propellers is addressed by a Boundary Element Method for potential compressible flows around 3D lifting bodies. Stemming from the knowledge of the inflow incoming to the propeller, the proposed model is used to predict blades unsteady pressure distribution. These data are then used within part III of the research project as input to the aeroacoustic solver for the prediction of the noise generated by the propulsive system of the vehicle.
