Dynamic analysis and CFD calculation of a differential control type for ducted fan UAV

In recent years, “Smart City” has been developing and need to obtain accurately information of the city, As a movable platform for sensing detection system in air, the ducted fan UAV will play an important role for information collecting in the complex urban environment. Because the complexity of traditional ducted fan UAV's control organ, which has strong air coupling, so there has big challenge if this kind of ducted fan UAV is used in the complex urban environment. A differential control type for ducted fan UAV has presented in this paper, through dynamics analysis and CFD simulation to the traditional ducted fan UAV and differential control type, the differential control type can keep the yaw stability of aircraft when the control flaps has a rational angle and stable lift when the control flaps become, meanwhile it can control the pitch and roll attitude through the differential motion of control flaps. So this differential control type is feasible and possesses some advantage over relative to traditional type if processing reasonable optimization and design.
