 Ship / 2255020
Proposed catamaran has two hulls in form of oblong cylinders with cone-shaped fore and aft extremities, decks, propellers and steering gear. Hulls are interconnected by means of horizontal transversal rods in above-water portion and longitudinal keel girder which is connected with hulls by means of inclined rods in under-water portion of hulls. Said connection members form truss together with hulls in form of triangular prism; adjoining to bases of this prism are pointed sections in form of triangular pyramids whose vertices lie on ends of keel girder. Angle at which faces of prism intersect is equal to 40-70 deg.

(57) Abstract: The invention relates to shipbuilding and can be used to create high-speed vessels with increased seaworthiness. High-speed Multihull vessel has a surface habitable unit and two buildings with ship lines. These enclosures are linked to the surface unit racks. The vessel is supplemented by a third body. Corps crossed the free surface of the water and are located relative to each other by a triangle in the plan. These enclosures have broken lines. The ratio of the length of each casing L to its width is not more than 8. The technical result of the invention is to reduce the towing resistance of the ship at the speed corresponding to the planing mode, i.e. when the numbers Fruta displacement of one building more than 3. 3 Il. The invention relates to shipbuilding and can be used to create high-speed vessels with increased seaworthiness. Well-known and widely used "shear waves" double-hulled vessels (catamaran) with cases of high-aspect ratio (ratio of length 1. to width) of one hull L/B1= 12...16) having a curved (smooth) lines (for example, Jacotot of the inhabited surface of the block and intersecting the surface of the water blocks with curved lines, connected to the surface unit thin streamlined struts. "Shear wave catamarans have increased seaworthiness courts than traditional forms. Housing high-aspect components cleave wave catamarans provide a high driving performance in the transition from swimming to gliding) mode (at a relative speed in the form of a number Fruta displacement of the one chassis FnVI= v/(W10.333g)0.5< 3, where v is the speed, m/s; W1the displacement of one chassis m3; g = 9,81 m/s2. The lack of "shear waves" double-hulled vessels at higher speeds is a large towing resistance. The task of the claimed invention is to reduce the towing resistance "shear wave" of the ship at the speed corresponding to the planing mode, i.e. when the numbers Fruta displacement of one building more than 3. This technical result is achieved by the fact that the known high-speed shear wave Multihull vessel having a surface habitable unit and two buildings with ship lines that intersect the free surface udyogini relative to each other by a triangle in plan, have broken lines, and the ratio of the length of each casing L and width B1(L/B1) is not more than 8. The addition of the third case provides the vessel, consisting of a small lengthening of sufficient length and surface area of the unit, as well as longitudinal stability. The use of small elongation, L/B1<8, and broken contours, provides a small vessel towing resistance in planing. The invention is illustrated by drawings, where Fig. 1 shows a side view of the proposed vessel, Fig.2 - the appearance of this vessel in plan in Fig. 3 - view of the proposed vessel in front. Surface habitable unit 1 vessel is connected to three intersecting the free surface of the water with small elongation 2 with thin legs 3. In this case, all of the housing 2 have a broken shape of the ship hull 4. When the vessel is at high speeds, corresponding to the planing, small elongation, with broken lines, there is a considerable lifting force that provides ascent (decrease precipitation) of the vessel. As a consequence, the incoming flow is flown not the entire surface of each body is the resistance of the vessel - prototype consisting of elongated buildings with curved lines. Therefore, the proposed vessel has the advantage that part of the towing resistance in comparison with the prototype. High-speed shear wave Multihull vessel having a surface habitable unit and two buildings with ship lines that intersect the free surface of the water and related surface unit racks, characterized in that the ship is supplemented by the third case, while buildings are located relative to each other by a triangle in plan and have broken lines, and the ratio of the length of each casing L to its width is not more than 8.
