N2 - Four-rotor dish-shaped UUV is a new type of equipment for aquaculture to survey water pollution, which can land on the seabed by extending the hydraulic support. In this paper, the instability state of the UUV is defined, and the mathematical model of the instability state is established. Unstructured mesh generation is carried out using Ansys ICEM. Considering the coupling of the UUV between flow field and seabed, the numerical simulation calculation is completed by using Ansys CFX. 4 different flow velocities, 4 different distance and 4 different attack angles are calculated, and the curve of the fluid force and torque for the UUV landing platform is drawn. Finally, the relationship between the stability of UUV and the variables is analyzed and summarized. Application of this landing method and the results can be used for practical design and experiment purposes for the new UUV platform.
