Propulsion principle and manipulation technology of the bionic turtle hydrofoil were researched. The motion characteristics of hydrofoil propulsion were analyzed through real-time state monitoring and data analyzing of the marine turtle movement. The principle of hydrofoil propulsion and the coordinated multi-drive manipulation methods were discussed from the aspects of hydrodynamics, flow field and so on. Based on it, the hydrodynamics equations of hydrofoil propulsion were established. In order to study the evolution of flow field and its effect principle, numerical simulation of hydrodynamics of the hydrofoil motion was carried out by the Fluent software, effects of flow field and geometric parameters of the hydrofoil on propulsion performance were analyzed, and morphological characteristics of the hydrofoil motion trajectories were obtained. A modularized bionic hydrofoil propulsion vehicle was developed, a series of experiments about the vehicle motion capability were conducted in the pool, the manipulation technology of the vehicle motion was discussed. The tested results prove realibility of hydrofoil propulsion and feasibility of manipulation technology for the bionic hydrofoil propulsion system.
