On Hydrodynamics of Bionic Flapping Hydrofoil Propeller

The bionic flapping hydrofoil propulsion, as a new propulsion mode, is different with the traditionary screw propeller, and it has attract the interest of the technologist in the aeronautics, astronautics and marine field. The underwater bionic flapping hydrofoil propeller is a system which can produce the thrust and can also produce the control force. This paper describes a hydrodynamics model of the bionic flapping hydrofoil propeller. The model is used to simulate the hydrodynamics of the bionic flapping hydrofoil propeller. The simulation results indicate that the hydrodynamics model of the bionic flapping hydrofoil propeller is effective and accurate. The results also show that the flapping hydrofoil propeller can create the steady thrust.
