摘要
A propeller for ship propulsion consists of trapezoidal helically shaped wings (3) which are arranged planetarily about its axis of rotation advancing axially in a screwing mode. The wings of the propeller, constituting a portion of a complete spiral of a screw, are disposed at a certain distance (radius) from their axis of rotation, on the same or on a different perpendicular or transverse plane to the axis of the hub (1) and at the same or a different radius, being mounted on the hub by means of arms (6). The wings (3) tend to momentarily (instantaneously) immobilize a mass of water in which the propeller is operating, thus attaining a support on a solid and steady (or almost solid and steady) body/mass and consequently causing axial advance in a screw-like manner like a worm screw.
