Disposition of groups of propulsion to jet on boats. (Machine-translation by Google Translate, not legally binding)

摘要

Arrangement of jet propulsion groups on ships, characterized in that its component part is a propeller-type pump with rotating propeller blades, into which enters a taper intake pipe converging towards the pump and having a taper angle no greater of 8 degrees and from which emerges a tapered outlet pipe diverging in the direction of the outlet, having a taper angle of no more than 8 degrees, in which several propulsion groups are placed symmetrically opposite the ship's axis within the side walls, having their intake openings protected by a net, which, in addition, in large boats having a flat bottom, the pump is positioned outside the axis of the ship, the suction pipe is mounted in a certain position of the area between the side wall and the bow, while the outlet pipe is mounted towards the side wall, preferably very close to the passage of the pro inside the side wall, whereby the complete propulsion groups are situated symmetrically opposite the longitudinal axis of the ship, and at the stern of the ship the pump is placed outside the ship's axis, the suction pipe being in the lateral wall, in the narrowest, next to the passage from the side wall to the stern, while the outlet pipe is placed in a certain position in the area of the stern of the boat, whose stern can be designed in steam cutting, whereby the complete jet propulsion group is mounted facing symmetrically with respect to the longitudinal axis of the ship, and that the motor shaft of the pumps is displaceable, at a beta angle with respect to the planes parallel to the longitudinal axis of the ship.
