摘要：
To investigate the underwater non-screw propulsion method, research of bionic turtle hydrofoil propulsion technology was performed. A bionic-hydrofoil propulsion system named "Leonardo" was developed, which included the propulsion executive system, control and sensor system, and security detection system. Then test experiments with variable motion parameters and bionic system direct navigation and yawing on the spot were carried out, and the influence that hydrodynamics of hydrofoil propulsion have on the bionic system motion in numerical simulation experiments was verified. The test results showed that hydrofoil stroke spin angular velocity had a decreasing acceleration proportional effect on the direct navigation speed of the system, and hydrofoil azimuth spin amplitude influenced the stability of bionic system speed to some degree. Furthermore, a first increased and then decreased action on the direct navigation speed and acceleration of the system was shown, and the influence curve of palmiped offset angles on the yawing angular velocity of the system had a cosine shape. This hydrodynamic performance research of the bionic hydrofoil propulsion technology provides significant basis for study on control strategy of bionic-hydrofoil propulsion system movement.
