(57) Abstract: The invention relates to shipbuilding and for the profiling of the bottom of the hull speed of a vessel with a gas caverns and water jet. Each of these drivers has a fairing intake. Speedster includes a housing with side cheeks, sidewall and transom. Its bottom has one or more transverse steps. The vessel is made with the air supply system or gas for forming artificial gas cavities in the space between the steps, the side skegs and transom. Plots of the bottom of the hull on both sides of the fairing intakes of jet propulsion in the area of the end portion of the fairing is made from a negative or reverse deadrise of the frames. The length of these sections is not less than 0.02 L and is measured from the transom of the hull, and the value L is the length of the vessel. The width of these areas is equal to not less than 0.02, where the value In the maximum width of the housing, within which are located the fairings intakes of jet propulsion. The vessel may have two or more buildings. It can additionally be equipped with engines other than jet. The technical result of the implementation from the schA, washed in the area of the water jet propulsion on both sides of the keel of the hull. 11 C.p. f-crystals, 17 ill. The invention relates to the field of shipbuilding and for the design of the bilge hull speed of a vessel with bottom gas caverns, having one or more jet propellers. Known Speedster with a jet propulsion engine, comprising a housing with side cheeks, cross step, side skegs and transom, with the air supply system or gas for forming artificial gas cavities in the space between the redan, sidewall and transom, and the fairing of the water jet propulsion device, made in the form of a keel of the hull, the bottom surface which is a smooth continuation of the bottom front of the redan (US 4587918 A, IPC B 63 B 1/38, published 13.05.86), adopted as a prototype. The disadvantage of such a vessel is not covered by the gas cavity bottom plots located on both sides of the keel of the hull in the area of the water jet propulsion. Consequently remains is washed with water a large area of the bottom. Features gas cavity to reduce the towing resistance underutilized about is achieved by that high-speed vessel with a gas cavities and one or more water jet, each of which has a fairing intake, comprising a housing with side cheeks, sidewall and transom, one or more transverse steps on the bottom and the air supply system or gas for forming artificial gas cavities in the space between the steps, the side skegs and transom, lots of bottom, located on both sides of the fairing intakes near the end of their part, have negative or that the same reverse deadrise of the frames. These areas represent a length of not less than 0.02 L, measured from the transom of the hull, and a width of not less than 0.02 B, where L is the length of the vessel, B - maximum width of the housing, within which are located the fairings intakes of cannons. Implementation of sections of the base plate, located on both sides of the fairing intakes near the end portions thereof, with a negative or reverse deadrise of the frames allows you to remove the surface of the cavity near the fairing from the intake openings, thus preventing the ingress of gas into this hole, and simultaneously allows to increase the area of the bottom, insulated from contact with in the exploring the impact of fairings vodozabornykh jet propellers on the towing resistance of the vessel. The effectiveness of the bottom of the gas cavities increases. Can be used one of the following forms of fairing water jet propellers:the fairing of the water jet propulsion, which with a length of L*measured from the transom of a fairing to a point spaced at a distance (0.01-0.20)L noobee intake hole has a rectangular or trapezoidal outer contour of the ribs, and the rest of the nose of the fairing is made with keeled ship lines; - fairing vodozabornykh jet propellers, which with a length of L*has a rectangular or trapezoidal outer contour of the ribs, and the rest of the nose of the fairing is made with keeled ship lines, with cheekbones fairing along the entire length are rounding radius (0.01-0.20)b, where b is the maximum width of the fairing; the fairing of the water jet propulsion, which with a length of L*has a rectangular or trapezoidal outer contour of the ribs with sharp cheekbones, and the rest of the nose of the fairing is made with keeled ship lines with cheekbones with rounding glad the t rectangular or trapezoidal outer contour of the ribs with sharp cheekbones or cheeks with a radius of less 0.1 b and nasal area fairings are made with fillet and has arrow-shaped in the plan. The use of these forms allows you to combine simple enough contours of the fairing with its effective operation, i.e., protection of water from entering the gas from the cavity when the maximum value of reducing the hydrodynamic resistance provided by the creation of cavities. To further simplify the shape of the nasal part of the fairing at least one of the intakes fairing may be extended towards the bow of the boat at least to the nearest step, and the initial part of its bottom surface is either slowly transforming into a bottom surface of the front of the redan, which extended fairing, either in place of contiguity to step deep in the hull of the vessel relative to its bottom surface located immediately before the step, the value of (0.05-0.50)b. Execution jet propellers placed partially behind the transom of the hull allows to increase the useful internal volume of the vessel, as well as to increase efficiency of gas cavities to reduce hydrodynamic resistance, because slusa part of the fairing intake of at least two jet propellers are made asymmetric with respect to the median plane of the fairing. This option fairings may occur if the vessel several jet propellers, intakes are placed each in its fairing, either in the case when part of the vessel consists of two or more buildings. This option fairings may allow to increase the area of the bottom covered caverns. All of the above options fairing intakes of cannons along with the proposed technical solution can be used if the vessel other types of propulsion other than water, and when the composition of the vessel includes two or more blocks. If the speed of the vessel consists of two or more buildings, a separate housing may have a cross-steps, is made asymmetric with respect to the median plane of the individual case. The shape of the contours of the fairing of the water jet propellers must be chosen for each particular vessel based on the conditions of ensuring the efficient operation of the propulsion and minimize the magnitude of the towing resistance of the hull. The invention is illustrated by drawings, where: in Fig. 1, 6, 9, 14-17 schematically in axonometric projection izobrazbe on the transom of the vessel, lying up in the bottom of Fig. 10-13 - cross-section of the bow of one embodiment of the fairing of the water jet propulsion. The bottom lines of all proposed options hull /1/ characterized by the presence of nasal cross step /2/, the bottom surface to which smoothly into the bottom surface side skegs /3/. Nasal cross-step /2/ and side skegs /3/ together limit of the bottom recess, in which is formed one or more gas caverns. To protect water from getting into them gas out of the caverns at the bottom of the vessel is installed fairings /4/ intakes /5/ water-jet propulsion. The height of the fairings are selected such that their portions of the bottom surface adjacent to the intakes /5/, they were washed with water throughout the range of operating speeds of the vessel at given angles of pitch and roll, thus preventing the ingress of gas from the cavity in the water intake holes. In Fig. 1 shows the most General version of the proposed vessel having a bottom recess, within which is placed a few additional cross-steps /6/. The number of fairings /4/ intakes /5/ corresponds to the number who revoy pitching vessel may be equipped with a longitudinal keel /7/. In Fig. 2 and 3 shows the fairing /4/ water /5/ made according to and. St. N 1081935. As can be seen from Fig. 3, portions of the bottom of the /8/ on both sides of the fairing /4/ have a positive deadrise of the frames. For this reason, near fairing /4/ there is a significant area, is washed with water (hatched area in Fig. 2). The presence of this zone leads to a reduction of the area of the bottom, which could be using the cavity is isolated from contact with water, and as a consequence makes less efficient use of bottom gas caverns. In Fig. 4 and 5 show a variant of the bilge lines, which eliminates the above drawback. Proposed contours (Fig. 5) are characterized by the presence of but both sides of the fairing /4/ water /5/ sites bottoms /9/, having a negative or reverse deadrise of the frames. The width of each area is not less than 0.05 B, measured from the fairing, the length is not less than 0.02 L measured from the transom of the hull. In this case, inside the recess is washed with water leaving only small areas near the bottom of the transom (the hatched region in Fig. 4) necessary to ensure the closure of caverns. The efficiency of the bilge gas cavity with F, using the proposed solution. In Fig. 6 depicts a high-speed vessel, in which the fairing /4/ water /5/ jet propulsion with a length of L*measured from the transom of a fairing to a point spaced at a distance (0.01-0.20)L noobee of water, has a rectangular (Fig. 5) or trapezoidal (Fig. 7) on the outer perimeter frames, and the rest of the nose of the fairing is made with keeled ostrovskoye ship lines. Cheekbones fairing /4/ the entire length can be accomplished by rounding (Fig. 8) of radius r, equal to (0.01-0.20)b. In Fig. 9 shows a high-speed vessel, in which the aft section of the fairing /4/ water /5/ jet propulsion length L*has sharp cheekbones or cheeks with a small radius (less 0.1 (b), and the rest of the nose of the fairing is made with rounded arrow-shaped form in plan (Fig. 10-13). High-speed vessel (Fig. 14) may have a fairing /4/, which extended towards the nose of the ship up to the first transverse step /2/. In this case, its bottom surface is smooth continuation of the bottom before the first crossover sponson /2/. Not possible when the additional transverse steps /6/. In this case, the bottom surface of the fairing is smooth continuation of the bottom before additional crossover sponson, which extended fairing. Possible case (Fig. 16), when the optimal can be such fairings /4/ intakes /5/, the bottom surface of which is in the nose of the fairing is deepened in the hull of the vessel relative to the bottom surface, located directly in front of the redan, which extended the fairing to a height h equal to (0.05-0.50)b, where b is the maximum width of the fairing. In order to reduce the negative impact of the fairing /4/ vodozabornykh /5/ on the gas cavity jet propulsion can be partially removed from the transom of the vessel (Fig. 17). When the movement speed of the vessel, which plots heads located on both sides of the fairing intakes near the end portions thereof, is performed with a negative or reverse deadrise of the frames (region /9/ in Fig. 5), the gas from the cavity fills this niche formed, border closures cavities on the surface of the plate is shifted closer to the transom of the vessel, and the area of the bottom covered by the cavity increases (Fig. 4). In the moistened surface to provide the gas cavity increases. 1.
