Abstract: To overcome the shortcoming of the current ducted tail rotor that is unable to provide lift force, a ducted tail rotor with asymmetric layout was proposed. The aerodynamic performance of the topological structure of the ducted tail rotor was theoretically and numerically studied. The effects of the flight speed and opening angular displacement on the lift force, pull force and moment were obtained respectively. The aerodynamic characteristics of the symmetric and asymmetric ducted tail rotors were compared. It was shown that this ducted tail rotor with asymmetric layout can not only produce axial force to control aircraft attitude, but also produce radial force to provide additional lift force for the aircraft. Therefore, proposed ducted tail rotor with asymmetric layout has certain feasibility and application value.

Key words: computational fluid dynamics, ducted tail rotor, asymmetric layout, aerodynamic characteristics
