Abstract
With the environmental deterioration and people's increasing attention to its protection, it is urgent to save energy and reduce emissions from ships. Reducing ships' drag and using a biomimetic propulsion device as the alternative power to drive them is an effective solution. In this paper, a ship propulsion unit composed of movable flapping foils is proposed. The flapping foils make a reciprocating treading motion in water to generate power to propel and heave ships. By heaving ships out of the water, the drag of the hull is eliminated, which considerably reduces energy consumption. By controlling the attack angle of flapping foils in groups, a good motion control performance can be obtained. Compared with hydrofoil ships, the propulsion unit can heave the ship out of the water at a low speed, and it utilizes both the lift and the drag from foils. It can actuate the ship with 6 degrees of freedom.
