In this work aerodynamic performance simulations of the full scale BO105 main rotor in hover flight conditions are conducted using the CFD Euler/Navier-Stokes flow solver FLOWer. Navier-Stokes calculations were made for a wide range of rotor collective pitch angles and compared with experimental data. In a first approach the rotor performances were simulated assuming the blades as rigid bodies. Large overestimations were found in the comparison of the predicted rotor thrust and power values with the experimental data. Substantial improvement of the results was obtained taking into account the aero-elastic blade deformations.
