The problem of aerial docking of fixed-wing UAVs restricts the development of the chained-wing UAVs. The aero-dynamic modeling and path planning of the wing docking process of fixed-wing UAVs were investigated. At first, the aerodynamic model of the wing docking process of fixed-wing UAVs was established by using the numerical lifting-line theory. The aerodynamic coupling effects of the UAVs at different relative positions were analyzed. Then, the path planning of the wing docking process was considered as a weighted directed shortest path problem. The optimal wing docking path was obtained by using the path planning method based on the Dijkstra algorithm. Numerical simulation results demonstrate that the aerodynamic modeling method can reliably describe the aerodynamic coupling effects during the wing docking process. The optimal wing docking path significantly reduces the wingtip vortex interaction.
