Abstract

The invention relates to a propulsion unit consisting of a housing having an inlet at the bottom and an outlet at the side on which a motor having a shaft is accommodated. The shaft holds an upper rigid disk that is connected to a motor. To the rigid disk, a plurality of disks, having a gap between each other, and formed as rings with a hole, having an outer diameter R and an inner diameter r, are connected. The disks are fastened to the rigid disk by screws rivets or other fastening means. During operation water is led into the inlet at the bottom of the housing and further through the holes of the disk assembly after which the water is moved horizontally between the disks to the periphery of the housing towards the outlet. In this way a silent, highly efficient propulsion unit is provided. The invention also relates to the use of the propulsion unit as a motor for a seagoing-, lake or like vessels, such as a boat, and/ or a use as a submersible pump when a hose is connected to the outlet via a nozzle.
