3D scene simulation of UAVs formation flight based on FlightGear simulator

To solve the problem of scene simulation for unmanned aerial vehicles (UAVs) formation flight, a method based on FlightGear is proposed. The 3D scene simulation system scheme is designed. The formation flight control system of leader-followers is established by the Matlab/Simulink, where the flight state data of UAVs is output to the FlightGear simulator by the interface of Matlab. A 3D model of UAV is designed based on AC3D software. A friendly man-machine interface is designed, which combines the simulation data with 3D animations, to make the simulation results more exhaustive. Finally, the UAVs formation flight scene simulation results show the effectiveness of the proposed method.
