Design of the propeller for tilt-rotor UAV

Tilt-wing and tilt-rotor unmanned aerial vehicles (UAVs) represents promising direction for the future development. This paper presents the method for the preliminary design optimization of the propeller for such vehicle. It should be capable to generate high thrust in both forward flight and hover modes. This brings design challenges for the propeller aerodynamic design. All considered variants have same number of blades, engine power, airfoils and diameter. Thrust in forward cruise speed 30 m/s and in hover is computed and compared by the means of Pareto diagram. Choose of the optimal RPM is based on the computation results
