Innovative Design of a Submersible Multimode High-Speed Unmanned Surface Vehicle

In this paper, a submersible multimode high-speed unmanned surface vehicle (USV) is studied. Firstly, the type design and general layout design of the USV are introduced, and then the sailing performance of the USV is simulated and analyzed. Importantly, according to the multi-modal characteristics of the USV, a repeatable submersible system is designed, and the repeatable surfacing and diving modes are studied. Finally, the control system of the USV is studied and designed. The experimental results show that the USV has the characteristics of high speed and flexible maneuverability, which has certain practical value.
