    The invention relates to shipbuilding, in particular to the design of the stern end of the vessel. The purpose of the invention is to increase the efficiency of the propulsion system protection. The feed trim 2 is streamlined and tapering in the direction of the stern to a sharp wedge. On the lower and outer edges 3, trimming 2 is always wider than in the overlying area, thereby reducing the ship’s resistance and the required drive power when running in clear water, while going backward, the running and steering controls of the vessel are protected from contact with ice. 3 hp f-ly, 1 ill.

    The invention relates to shipbuilding, in particular to the design of feed adjustments.
    The purpose of the invention is to increase the protection efficiency of the propulsion system.
    The drawing shows the aft end of the hull with streamlined trim.
    The aft end 1 of the ship's hull has a bulk feed trim 2 streamlined, which tapers in the direction of the stern to a sharp wedge. This bulk cladding 2 is made along its lateral lower and outer edges 3 always wider than in the region located above. In addition, feed adjustments can extend in some part above and below the icebreaking waterline 4.
    The bulk body of the feed trim 2 toward the front part smoothly passes into the contours of the feed end of the hull. The lower side 5 of the feed adjustment in the plane of the frames is preferably flat or / - shaped; it can also be matched to the outline of the jets from the screws. Waterlines 6, including an icebreaking waterline 4, can form an angle of less than 20 ° with the longitudinal vertical plane of the vessel. The lower side of the feed adjustment towards the stern is directed downward. ''
    In icebreaking vessels with nozzle propellers, the feed adjustment cross-section smoothly passes to the outer contours of 7 adjacent screw nozzles 8.
    On the underside 5 of the feed adjustment, behind each steering pen 9, are located adjacent to each other several parallel longitudinal planes of each steering feather made of thin profiles or ice sheet 10. In addition, the lower outer edges 3 of the body of the feed adjustment 2 over a long section between the screws and poop can be made acute-angled.
    Feed dressing 2 is carried out Streamline, tapering in the direction of the stern to a sharp wedge and along its lower external edges 3 is always wider than in the region located above, due to this, the resistance to the course of the vessel and the required drive power when running in clean water is reduced, and, in especially in reverse, the ship’s steering and control are protected from contact with ice.

    Claims (4)
    [1]
    Claim
    1. Feed adjustment of an icebreaking vessel with ice-breaking devices located above the propellers with nozzles and feathers of the rudders and made streamlined, tapering in the direction of the stern to a sharp wedge, and in the bow smoothly interfaced with the aft part of the hull, while the aft part of the adjustment is located below its bow, characterized in that, in order to improve the protection of the propulsion complex, the cladding is made expanding to its bottom surface, and each of its waterlines forms with etralnoy vessel plane angle less than 20 °, wherein the keel nadelki surface is flat or V-shaped, with the aft portion nadelki located behind the propellers and rudders feathers and the side surface of the bottom nadelki abut the surface at an acute angle.
    [2]
    2. Feed adjustments according to claim 1, with the fact that it smoothly interfaced with screw nozzles.
    [3]
    3. Feed adjustment according to claim 1, with the fact that in each of its cross sections it crosses the icebreaking waterline of the vessel.
    [4]
    4. Feed adjustment according to claim 1, characterized in that the ice-breaking devices are installed on the bottom surface of the feed adjustment.
