Abstract

This invention relates to a vessel propulsion system with a toothed propulsion wheel which dips partly into the water, the rotational axis of the said wheel being essentially at right angles to the direction of propulsion of the vessel propulsion system. The vessel propulsion system also exhibits a cover partly enclosing the circumference of the propulsion wheel, said cover being arranged in relation to the propulsion wheel such that with operation of the vessel propulsion system a circulating flow is formed in the rotational direction of the propulsion wheel between the circumferential surface of the propulsion wheel and the cover. To improve the efficiency of the vessel. Propulsion system it is suggested with this invention that the leading and trailing faces of each of the teeth formed on the propulsion wheel exhibit a spherical, convex surface, that the tooth tip of each tooth is curved convexly in the axial direction and that the starting point of the radii of curvature of the spherical surfaces and the contour of the tooth tip are located in a plane extending orthogonally to the rotational axis of the toothed wheel, said plane also including the center point of the propulsion wheel in the axial direction.
