     The invention relates to shipbuilding, in particular to icebreaking vessels.
    The purpose of the invention is to increase the ice permeability by reducing adhesion and friction between the front surface plating and ice.
    Figure 1 shows the location of the nozzle for feeding the working mixture in the outer skin of the frontal surface I of the vessel; Fig. 2 shows the gas supply circuit; to the nozzle I in Fig. 3, the bow end of the vessel with a plating heating device, side view; 4 - the same: heating with ballast water or fuel; figure 5 - the nasal tip of the vessel, the heated piping system in which flows a liquid or gaseous medium, side view.
    j The icebreaking vessel has a forward-inclined frontal bow in the bow.
    The surface 2, which, at its outer lateral edges, is bounded by two side edges 3, which are partially curved, mainly in the longitudinal direction. cue to, located above the hull of the vessel. The front surface 2 of the bow 1 of the vessel, increasing from front to back, may be bent or bent down in the middle of the vessel. Along with the flat shape of the frontal surface 2 bowed at the front of the bow of the vessel 1, this front surface 2 can also be convex or concave. On the side of the frontal surface 2 of the bow of the vessel 1 goes to the side 4.
    In the area of the outer skin of the inclined frontal surface 2 of the fore part 1 of the vessel, i.e. in the bow zone, the device is provided for less (L

    nor the resistance of friction of ice, which consists of a certain amount -. in the outer skin of the frontal surface 2 of the output holes 5, through which a mixture of external water and hot exhaust gases of the machine installation 6 is ejected
    In the area of the outlet 5 is located the nozzle 7, made in the form of an ejector. The arrow 8 shows the supply of working water to the nozzle, and in the direction of the arrow 9, the flow of exhaust gas takes place, namely via the appropriately provided pipelines. (not shown).
    Outlets are provided in the decorative trim wherever the critical areas of the outer shell must be supported; hot and cold condition, which reduces the frictional forces of snow and ice acting on the outer hull of a ship hull. Along with sources of heat in the ship's hull, sources can also be used. Energy to create high frequency oscillations.
    S The exhaust gas for the nozzles 17 is through the gas exhaust pipe 10, coming from the main drive of the ship machine 6 and leading into the chimney 11. In the gas exhaust pipe 10 (figure 2) there is an exhaust gas boiler 12 and a silencer 13, The extraction of exhaust gas occurs predominantly between the waste-heat boiler; . C 2 and a silencer 13 through: a line 14 leading to the exhaust pipe 10 leading to the nozzle 7, and a blower 15 is connected to this line 14. With this blower, the exhaust gas is taken from the exhaust pipe 10 and fed to the nozzle 7. Exhaust gas supply The nozzle is controlled by a three-way valve 16. The exhaust gas from the three-way valve is returned via line 17 back to the gas exhaust pipe 10 between the silencer 13 and the chimney 11.
    The installation of nozzles 7 is carried out predominantly in the outer hull of the ship hull, namely in the critical outer zones that must be maintained in a hot condition; or in the outer skin of the frontal surface 2 of the fore part 1 of the vessel (FIG. 1),. The number of nozzles provided. 7 depends on the size of the hot zone or frontal surface 2. In addition, it is also possible to place the nozzles in other areas of the bow of the vessel or in the upholstery of the vessel adjacent to the bow of the vessel in the underwater part, through which friction resistance can be reduced ice, all of which are driven by a mixture of exhaust gas and working water.
    The embodiment shown in FIGS. 3-5 shows the bow, part 1 of the icebreaking vessel with a sloping, mostly flat frontal surface 2, which can be performed as a plug). to reduce the friction resistance of the ice, and this device 18 consists of a device 19 that heats the inclined frontal surface 2, the outer skin of the frontal surface 2 so that the frontal surface 2, because it has a contact In the presence of friction with broken ice, it has a temperature above the melting point of ice. The solid ice cover is indicated by the position 20, and the destroyed ice floes are indicated by the position 21 (FIG. 3).
    The hull areas of the hull, in which frictions of ice and traction occur, can also be heated from the hull of the hull, this heating is due to the location of tanks or compartments 22 for water, operational materials or liquid cargo adjacent to the outer hull of the hull. The reservoir fluids are brought to a temperature somewhat higher than the freezing temperature of the water, or to the silts, by directing the hot engine gases along the required outer skin surfaces. . Heating can also occur from the hull hold of the vessel by directing hot working fluids along the desired plating surfaces.
    It is preferable to increase the critical zones of the outer skin due to the wave-like appearance of the outer skin and thereby increase the heat supply. When you target

    consistent arrangement of the wave. the profile in the direction of the flow lines can simultaneously attenuate slime--. tangled in agitation.
    The heating device 19 narzgasnoy plating the frontal surface 2 of the bow of the vessel 1 (figure 4 and 5) can be done very different way. Preferably, the heating device 19 consists of a pipe line directed along said zones of the outer skin of the system 23, in which a liquid or gaseous medium circulates and in which the temperature is maintained.
    the melting temperature of ice is constant or exceeding by several degrees.
    The heating device 19 (FIG. 4) consists of an inclined frontal surface 2 located above the compartment 24, extending over the entire frontal surface. This compartment serves to receive, for example, water, ballast water, maintenance materials, or liquid cargo; but the compartment may also be filled with another, preferably liquid, medium. This medium, such as ballast water or fuel, is heated by a heating device 25 located outside or inside the compartment 24, the heating device 25 is installed inside the compartment 24, so that heat transfer from the heating device 25 to the medium in the compartment 24 occurs directly (Fig. 4). Electric contact heating can be used as a heating device 25, but heat exchangers can also be used, which, for example, are driven by the flue gas of the main ship water machine, so that no additional energy sources are required for heating the device 25. But conventional heating devices may also be used. It is essential that the entire front surface
    2, respectively, its outer skin, by supplying heat, has a temperature above the melting point of ice. It is preferable if the outer skin is maintained at a temperature that is constant and several degrees higher than the melting point of ice. Section 24 is located mainly in
    z. the sheathing of the hull.

    which must be maintained in a hot state. In addition to one compartment, several separate compartments may be provided. Instead of compartments, tanks can be used that are in contact with the heated outer skin, in which case the tanks are made out of a material having a high thermal conductivity.
    Here, the heating device 19 may also consist of a piping system 23 (FIG. 5) through which gaseous gas circulates.
    or liquid medium, moreover as
    gaseous medium, exhaust gases are used that are taken from the main propulsion vessel engine, or liquid media are used
    is brought to the desired temperature by the heating device 26 and then maintained at this level. Circulation of the heating outer skin of the medium is indicated by the position 27,
    Circulation of the medium takes place with the help of a pump 28. A piping system 23 may consist of piping located in the longitudinal direction of the ship’s hull on the inside, side
    external plating, from pipelines extending across the longitudinal direction of the vessel, as well as from pipelines formed in the form of a grid. In addition, it is possible
    to provide a frontal surface 2 with a system of compartments (not shown), along which the heated, continuously, i.e., hot exhaust gases or heated liquid medium, which gives
    its heat to the outer skin, and it is brought to the desired temperature.
    If an icebreaking vessel with an approximate pontoon-like nose has the greatest width
    If the underwater part of the vessel has lateral edges: which penetrate the waterline that narrows behind them on the bow of the vessel, then the side edges can be equipped with heating devices for supplying heat. The heating device is adjustable in such a way that the heat input is created in the lateral edges. 1 W temperature, providing the same lubricating film of melt water, is suitable for ice conditions.
    Preferably, the thickness of the water lubricating film optimally corresponds to the icebreaking state, i.e.
    the temperature of the heating device is suitable in applying to the respectively required thermal film. The water leaving the outlets in the bottom of the vessel may drain without. the addition of air or gas on the sides above the side edges in the direction relative to the longitudinal axis of the vessel.
