(57) Abstract: The invention relates to a small shipbuilding and for the creation of inflatable Multihull, mainly sports and recreational sailing catamarans. The hull has a convex shaped flexible membrane with fore and aft edges, a pair of inflatable chambers, the longitudinal dividing wall and two cavities. The partition is connected with a flexible sheath at its top and bottom edges. Each cavity formed by the inner surface of the flexible membrane and the adjacent surface of the dividing partition. Inflatable chamber positioned opposite each other on both sides of the baffle. The camera is placed in the cavities with the opportunity to interact with the shell and the partition. The partition is made rigid and are connected at their side edges, respectively, aft and fore edges of the shell. Inflatable chamber positioned along the length of the cavities. The cross sectional profile of the case is made in the form of two arcs. Arcs are connected with a common chord. The chord formed by the height of the partition wall in the cross section. The arc formed by the cross-section of the flexible sheath so that we have the following relation: (s/N ) , where s is the 3,14159... The technical result of the invention is to increase the speed of the vessel. 4 Il. / The invention relates to a small shipbuilding and can be used in inflatable Multihull collapsible vessels, mainly in sports and recreational sailing catamarans operated in open water. Known inflatable body collapsible vessel containing the circular cross-section flexible membrane, four inflatable chambers, the longitudinal dividing wall inside the mentioned flexible sheath and located around the circumference of the cross-section housing four cavities formed by the inner surface of the flexible shell and baffle, with each inflatable chamber located in the corresponding cavity with the opportunity to interact with a dividing partition [1]. In the known technical solution of the longitudinal partition wall forms an inner frame to increase rigidity around the entire circumference of the cross-section of the hull due to its compression inflatable chambers. However, this design, despite good stability, can not provide high speed is aderrasi flexible shell aft and fore edges, as well as massive longitudinal frame placed inside a flexible sheath and connected with their lateral edges of the aft and fore edge, respectively [2]. This design allows you to see some improvements in the form around the body and the stability of the vessel. At the same time in the present technical solution is not carried out, the profile contour of the shell, and not taken measures to improve the strength characteristics of the structure. The closest in technical essence and the achieved result is an inflatable body collapsible vessel catamaran base type containing convex shaped flexible membrane aft, fore edges and the Central part, a pair of inflatable chambers, the longitudinal separation of the flexible wall connected with said flexible sheath in its top and bottom edges and two cavities, each of which is formed by the inner surface of the flexible membrane and the corresponding surface of the flexible dividing walls, these inflatable chambers are located in the Central part of the flexible membrane opposite each other on both sides of the dividing flexible septum and placed in Bcoi partition [3]. In the known technical solution, the use of flexible longitudinal partition walls, connected with a flexible sheath at its top and bottom edges, and the preload mentioned partitions inflatable chambers allows to increase the stability of the hull, and the use of a pair of inflatable chambers located in the Central part of the flexible membrane opposite each other and placed in the cavities of the hull with the opportunity to interact with the Central part of the flexible membrane, prevents the hull from the action of bending moment. Having good resistance to water surface and high resistance to bending moment from the action of external forces, known inflatable body has a number of drawbacks, mainly related to the low speed of the vessel: high resistance to water flow due to the lack of good streamline shape; low strength characteristics of the housing due to the significant values of the stresses in the flexible sheath from the action of external loads, and a large gradient distribution of loads in the longitudinal direction; hydrodynamic losses associated with the turbulization of the flow from edge effects; loss enee forms the working surface of the flexible sheath. In addition, in the known construction, there are technological problems associated with the connection of the upper and lower sections of the flexible shell. The aim of the invention is to increase the speed of the vessel. This goal is achieved by the fact that the partition is made rigid and are connected at their side edges, respectively, aft and fore edges of the flexible membrane, while the inflatable chamber positioned along the length of the cavity, and the cross sectional profile of the case is made in the form of two arcs, United by a common chord, and the chord formed by the height of the partition wall in the cross section, the arc formed by the cross-section of the flexible sheath so that we have the following relation: (s/H) < , where s is the perimeter of the cross section of the flexible sheath; H - the height of the walls in cross section; = 3,14159... is a constant. A new technical solution should not be explicitly known in science and technology solutions, as the principle of the proposed technical solutions based on optimization of the whole complex of physical parameters and properties aimed at achieving the set goals. The first group of the complex otnositsea shell, what is achieved: a) the use of formative longitudinal rigid walls, on which is stretched a flexible membrane on the aft and fore edges, and upper and lower guides; b) profiling the cross-section of the housing, when the radii of the arcs formed by a flexible sheath, higher than the corresponding radii of the inscribed circles that improves the flow profile; C) the use of formative inflatable chambers located along the length of the cavities, allowing to maintain the shape of the shell in the Central, fore and aft parts of the hull, but also to reduce the turbulization of the flow from the edge effect. The second group of the complex is the minimization of the absolute values of the stresses acting in the flexible shell of the hull, which is achieved by: a) designing the cross-sectional profile of the housing in the form of two arcs, United by a common chord, and the chord formed by the height of the partition wall in the cross section, the arc - a cross-section of the flexible sheath so that the ratio of the perimeter of the cross section of the flexible membrane to the height of the walls in the cross-section less than the number that reduces the magnitude of the stresses acting in the radial and longitudinal n is; b) installing the supporting inflatable chambers that communicate with a flexible sheath along its entire inner surface. The third group of the complex is the provision of a smooth change in voltage in the longitudinal direction along the length of the flexible sheath from the action of external loads, which is achieved: a) the specified profile cross-section of the hull in accordance with the selected ratio of the sizes of the rigid wall and a flexible membrane, and also the condition of the inflatable chambers along the length of the cavities of the body and their interaction with a flexible sheath, since under the action of external loads on the hull and by the interaction of inflatable chambers with a flexible sheath in the past, there is tension directed along the normal to the surface, thus there is a slow increase of the longitudinal component of the voltage from the center to the fore and aft edges; b) by supporting the flexible membrane to the edges of the rigid partition, leading to redistribution of stresses along the length of the shell from the action of the shock and accidental loads. The fourth group of the complex includes the use of boundary conditions to minimize energy expenditure that d is spent on the formation and reinforcement of the working surface of the flexible sheath, not on the deformation of the flexible partition walls, distorting the shape of the flexible sheath; b) the use of hard edges of the dividing walls as a support for the flexible membrane on the aft and fore edges and upper and lower edge, respectively, which leads to the optimal tension of the flexible sheath. Compared with the prototype of the proposed inflatable body collapsible vessel catamaran base type has the following advantages:- inflatable body has the best faired as by profiling the cross-sectional profile, and through the use of formative hard partitioning and forming the inflatable chambers located throughout the length of the working surface of the flexible sheath; shell inflatable enclosure is designed so that the operating voltage from external loads less in absolute value and have a smoother distribution in the longitudinal direction; - inflatable enclosure provides a minimum loss of energy due to the interaction of inflatable chambers with a rigid wall, and the flexible shell of the better stretches, having a rigid support for stern, bow, bottom (kilovolts design; - when moving the inflatable hull reduced hydrodynamic losses from edge effects; - flexible shell is easier to manufacture and has the best integrity, as it has no connections on the side working surfaces of the hull (catamaran). In Fig. 1 schematically shows a collapsible vessel catamaran base type with two inflatable buildings, a General view in perspective of Fig. 2 - inflatable body collapsible vessel, side view, Fig. 3 - inflatable body collapsible vessel, a top view, section a-a of Fig. 4 - inflatable body collapsible vessel cross section B-B. Inflatable body 1 (Fig. 1) collapsible vessel catamaran base type contains a convex shaped flexible membrane 2 (Fig. 2-4) aft 3 and 4 nasal edges, a pair of inflatable chambers 5 and a longitudinal dividing wall 6, connected at their upper 7 and lower 8 edge with a flexible sheath 2. Inflatable body 1 also has two cavities 9 and 10, each of which is formed by the inner surface of the flexible sheath 2 and the adjacent surface of the partition 6. Inflatable chamber 5 are located opposite each other on both sides of the partition 6 6. Partition 6 is made rigid and are connected at their side edges 11 and 12 respectively with feed 3 and 4 nasal edges of the flexible sheath 2, and the inflatable chamber 5 are located along the entire length (throughout) cavities 9 and 10. The cross sectional profile of the housing 1 is made in the form of two arcs 13 and 14 are United by a common chord 15, formed by the height of the partition 6 in cross-section, and the arc 13 and 14 is a cross-section of the flexible sheath 2 so that we have the following ratio: the ratio of the perimeter of the cross section of the flexible sheath 2 to the height of the partition 6 in the cross section is less than the number , = 3,14159... . Inflatable body 1 can be made asymmetric about the longitudinal partition 6, which, in turn, may be solid or have openings. It is also possible different ways of connection edges 7, 8 and 11, 12 rigid partition 6 with a flexible sheath 2. In particular, to the best of forming a rigid partition 6 may be connected with a flexible sheath 2 through coverage and subsequent tension last at least two of its opposite edges. For best operanionala elements (Fig. not specified) at least one of its edge, for example the top edge 7. These options connect rigid partition 6 with a flexible sheath 2 allow the partition 6 as constant and variable height H along the length of the housing 1. For example, the profiling of the hull 1 in the longitudinal direction may be due to the gradual increase in the magnitude (s/H) with 2, 4 and nasal feeding 3 edges of the housing 1, to (s/H)max< in the Central part of the housing 1, and fore and aft end can have a rigid V-shape end, improve the hydrodynamic properties. Rigid partition 6 can be performed also collapsible. In this case, the shell 2 has a slit at the top and aft to install a hard partition 6 and the inflatable chambers 5. Inflatable body collapsible vessel catamaran base type operates as follows. When filling the inflatable chambers 5 air last interact with a flexible sheath 2 directly and indirectly through interaction with a rigid dividing wall 6 along the length of the cavities 9 and 10. In this case, the inflatable chamber 5 acquire the properties of farmoor is calculating the partition 6 does not dissipate energy in the partition wall 6, and all the energy from the inflatable chambers 5 is transmitted to the flexible sheath 2. Hard partition wall 6 also has properties forming and reinforcing element for inflatable body 1, as connected at their side edges 11 and 12 respectively with feed 3 and 4 nasal edges of the flexible sheath 2, and its upper 7 and lower 8 edges respectively with the top and bottom (keel) the edges of the flexible sheath 2, which is in this case a rigid support for fodder 3, the nose 4, the bottom (keel) and upper edges. In addition, the morphology of the structure is improved by profiling the cross-section of the inflatable body 1 due to the increase of the radii of the arcs formed by the flexible sheath 2, as compared with the corresponding radius of the cylindrical shell. Hydrodynamic perfect shape of the bow and stern parts of the inflatable body 1 allows to reduce the energy losses associated with the turbulization of the water flow from the action of the edge effect. Profiling the cross-section of the housing 1 in the form of two arcs 13 and 14, connected by chord 15, and the choice of the ratio between the height of the rigid partition 6 and the perimeter of Phnom and longitudinal directions from the action of external forces and a smooth change of the longitudinal component of the voltage, with regard to the bearing of the flexible sheath 2 to the edges 7, 8, 11 and 12 of the rigid partition 6 will lead to the best tension of the shell 2. The invention allows to improve the high-speed properties of the vessel catamaran base type, to improve its strength characteristics and to create a more perfect streamlined shape of the hull.
