Aerodynamic characteristics analysis and robustness analysis of ducted-fan UAV based on Magnus effect

Abstract

In this paper, a new actuator system of the ducted-fan Uninhabited Aerial Vehicle(DFUAV) is presented. 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 rotary cylinder and the downwash, which is known as Magnus effect. In this paper, the characteristics analysis of the presented DFUAV was simulated by Computational Fluid Dynamics (CFD) method, the controller based on the cascaded system modeling and the parameterization of thrust of DFUAV is designed and the robustness analysis is conducted.
