Abstract :
Uninhabited Aerial Vehicle(UAV) has been developed quickly for decades and a new kind of VTOL(Vertical Take-Off and Landing)UAV which is called Ducted-Fan Uninhabited Aerial Vehicle attracts more and more attention. This paper presents a new structure of the ducted-fan UAV. In this vehicle, the actuator system consists of four rotary cylinders which are symmetrically installed at bottom of inside duct. The force used for attitude stabilization is generated by the interaction between the surface of cylinder and the downwash, which is known as Magnus effect. In this paper, the aerodynamic characteristics of propeller-wing interaction for the ducted fan UAV were simulated numerically based on the Computational Fluid Dynamics (CFD) by means of sliding mesh technology.
