Abstract：In order to analyze the effect of speed on shipborne tethered unmanned aerial vehicle (UAV) system, a nonlinear dynamic model of the system is established, and the cable tension and UAV movement in different speed regions are numerically analyzed. In region I, the UAV phase trajectory is closed, showing single-period motion characteristics, and the end tension under the cable produces frequency doubling response; In region II, there are intersection points in the UAV phase trajectory, showing period-doubling motion characteristics; In region III, the UAV phase trajectory is not closed, the motion trajectory is not coincident, showing chaotic motion characteristics, and the end tension spectrum under the cable is continuous spectrum. The research results of this paper can provide theoretical reference for the safe flight of tethered UAVs following ships.
