<p>A propulsion system for water vessels comprises a rotor (14, 15) located at the rear end of the vessel body (10), which rotor rotates inside a shroud (12) and generates a thrust force, and a stator (16, 17) located behind the rotor for recovering the rotation energy created of the rotor. An unexpected high noise reduction is accomplished because the rotor (14, 15) is mounted on a hollow drive-shaft (19), through which an axle (18) extends which is fixed to the body (10) of the vessel, and which axle support the stator (16, 17) and the shroud (12) that surrounds the rotor, without further supporting devices. <IMAGE></p> |
