A two-dimensional model of the Weis-Fogh mechanism, which is a mechanism of hovering flight of small insects, is applied to ship propulsion. A model of the propulsion mechanism consisting of one or two wings in a square channel is proposed. The thrust and the drag on the wing, which are defined, respectively, the force in the direction of progress of the ship and that of movement of the wing, are measured. The propulsive efficiency is calculated and is high when the moving speed of the wing is small compared with the advancing speed of the ship. A model ship equipped with this propulsion mechanism is made and working tests performed. The applicability of this propulsion mechanism to actual ships is expected to be good.
