As a result of the relative motion between the wave energy absorbing fins 3 and the fluid, if the wave energy absorbing fins 3 and 9 move in the direction of the water flow and an angle of attack a is created, this flow causes the wave energy absorbing fins 3 and 91 to create a fluid force. is divided into a component perpendicular to the flow direction 1 (lift force L) and a component along the flow direction (drag force D); ) body forward? force 1'+・ acting in the direction of wave energy absorption fins 3, 9
The force FA acting in the direction perpendicular to the central plane of is expressed by lift force, drag force, and angle of attack α as shown in the following equation.

The forward direction is positive, and the force FA is counterclockwise based on the 111 forward direction of the hull, and the direction of 9<jo is j[. That is, if the value of force F.1. has a positive sign, a force that moves the ship forward is obtained. On the other hand, the force FA is a force exerted in the direction of suppressing the vertical movement of the hull, and reduces movements such as heaving and pitching of the hull.

By using fins with a wing cross-sectional shape that makes C. positive and the value of C.1. large (symmetrical wing cross-sectional shape with a blade thickness ratio of about 0.15 to 0.22), wave energy is transferred to the hull. It can be converted into thrust.
