The main objective of this paper is to investigate an underwater unmanned vehicle (UUV) which has both flapping-foil and gliding function. Firstly, the paper introduced the advantages of the flapping-foil & gliding UUV, and described the flapping-foil motion model of bionic object turtle in detail. Then, by using the dynamic meshing technology in the code Fluent, the numerical computations of unsteady hydrodynamic characteristic for single degree of freedom (1-DOF) flapping-foil movement was carried out, which demonstrated the mechanism of flapping- foil. During the computation, turbulence effects were taken into account, and the turbulent stressed was evaluated by means of the Realizable k-epsilon model. Finally, the kinematics simulation of the UUV was performed. The design on virtual prototype of the UUV was completed in UG software, and the prototype was processed in the digital factory. Moreover, we presented the corresponding solutions aiming at the problems of the assembly prototype.
