(57) Abstract: The invention relates to shipbuilding and concerns the design of a wing devices hydrofoils. Wing device has a hydrodynamic bearing surface. Bearing hydrodynamic surface rigidly attached to the hull by means of racks and divided into similar sizes of the upper and lower bearing surfaces, which are rigidly connected by the scope of the internal vertical posts with education in a constructive attitude bezriskovoj farm. The distance between the upper and lower bearing surfaces is 0.3 - 1.5 chord vertically and 0 to 1.5 chord horizontally with the possible removal of the bottom surface in the fore or aft relative to the upper. The technical result from implementation of the invention is to increase the stiffness and strength bezriskovoj farms compared with conventional beam design and as a consequence in the reduction of weight of the wing device with a large hydrodynamic size that allows for hydrofoils with a large displacement. 4 Il. The invention relates to shipbuilding and concerns the design of a wing unit (CU) of the courts on Java N. A., Masculina A. I. "Domestic hydrofoils", Leningrad: Sudostroenie, 1967 and Blumina C. I., Ivanova L. A., Mateeva M. B. "Transport hydrofoils", M: River transport, 1961. Classification of structural diagrams of RL with power point of view is given in Vakhitova M B, Zaharieva M. S., Snigireva C. F., "Calculation of wing device ships strength", Kazan: Kazan Tatar book publishing house, 1975 in the table.2 on page 10. Console single column KU with a split and a continuous monoacrylate apply to SPK with deep wings. Mnogotochie KU with continuous wings are used for the SEC with malomagnitnye wings. Mnogotochie KU with split wings are used for the SEC with emergent wings. There are projects with the SEC etazherochki KU. Current improvements KU aimed at improving the hydrodynamic characteristics or performance of the vessel. In the Patent of Russian Federation N 2006413, the IPC 63 In 1/24, 63 H 11/04, published 30.01.94, to ensure unseparated flow profile that is N. Boitsova designed wing, the upper suction surface which has a system of slotted nozzles associated with the cavity inside the wing, connected with gerv 63 In 1/24, published 27.01.96, offers a different twist along the span of the wing. From the Patent of the USSR N A published 26.01.70, known KU, in which the Central portion of the bearing surface is divided into two: the upper and lower surfaces. In RL, protected by the Patent of Russian Federation N 2057674, the IPC 63 In 1/26, published 10.04.96 made asymmetrical profile side racks aft of the wing above the waterline operational speed, which increases seaworthiness. The patent of Russian Federation N 2059513, the IPC 63 In 1/28, published 10.05.96, provides for the implementation of each HRSG with supplementary stand with attached to it a horizontal wing, which improves performance. The stiffness of the hydrodynamic bearing surfaces of all the above types of KU bending is small due to the small thickness of the profile. Fender and rack do not create a unified power structure, perceived workload separately. The increase in displacement at the limited speed of the vessel leads to an unacceptable increase in the relative weight of KU and the unprofitability of the SEC as a vehicle. In the monograph Shanenko N. N., Kutenkov B. P., Tarasov, I. K., "hydrofoils", Leningrad : Sudostroenie, 1981 in Fig. 1.5 page 17 shows the statistics of the relative weight of the TOP 25%. Extrapolation according to the displacement of 1000 tons results in a 50%. Greater bending stiffness is selected prototype - KU, described in UK patent N 572413, the IPC 63 In 1/30, published 08.10.45. This KU contains slotted wings attached to the hull with the help of shock absorbing devices, and hydrodynamic surface of each wing is divided into two: the upper and lower bearing surfaces being rigidly connected at the ends and at intermediate points of the inner vertical wing elements with education in a constructive attitude bezriskovoj farm. The prototype has the following disadvantages:the mounting wings are provided only through a shock-absorbing device, which can lead to resonance phenomena with some combinations of SEC speed and wave height, - split the wings, substantially projecting beyond the casing unacceptable to many layout solutions SPC, especially with a large displacement. The present invention is the development of KU, which can be implemented for the SEC large displacement, free of the above disadvantages of the prototype. The technical result from the use of KU is to increase the mass of KU with a large hydrodynamic size. This result is achieved by the fact that KU containing hydrodynamic bearing surface rigidly attached by struts to the hull, this hydrodynamic surface is divided into two similar in size to the upper and lower bearing surface rigidly connected to the swing of the internal vertical posts with education in a constructive attitude bezriskovoj farm, and the distance between the upper and lower bearing surfaces is 0.3-1.5 chord vertically and 0-1.5 chord horizontally with the possible removal of the bottom surface in the fore or aft relative to the top. The proposed KU is illustrated in the drawings, where Fig. 1 shows a structural diagram of a typical KU, Fig. 2 - the location of the upper and lower bearing surfaces without displacement relative to each other horizontally in Fig. 3 - with removal of the lower bearing surface in the nose, and Fig. 4 - aft relative to the upper bearing surface. To the hull 1 by means of racks 2 fixed biplane wing 3. The upper 4 and lower 5 bearing surfaces have a wing profile, mounted at an angle of attack, and are connected to each other internal vertical posts 6. Adopted the following denoted by the sheer surface 5 relative to the top 4. The height H may vary in the range of 0.3 - 1.5 chord, removal and within 0-1.5 chord. Biplane wing could be swept and/or deadrise. When entering the cruising mode, the vessel will be fully retained lifting force occurring on the upper 4 and lower 5 bearing surfaces of the wing 3 in the form of a distributed scale hydrodynamic loads. This distributed load causes bending bezriskovoj farm between the posts 2, rigidly connecting the wing 3 and the hull of the vessel 1, which is implemented in the form of longitudinal forces in the upper 4 and lower 5 bearing surfaces, and local bending of the upper 4 and lower 5 the bearing surface between the inner vertical posts 6. To assess the effectiveness of the proposed KU calculations to compare the weight and drag of the biplane and monocryl, creating the same lifting force. The number of internal racks for half of the symmetric biplane varied from one to eight, the moment of inertia of the cross section of the racks were taken equal to one, ten and hundred moments of inertia of each wing surface. The maximum bending moment in the biplane reduced to 7% of maximum torque in monocryl, the mass of the biplane to 50% by weight of monocryl. Hydrodynamic The P> Thus, the proposed RL SPK provides increased strength and rigidity, a corresponding decrease in the mass of the KU while maintaining high reservoir quality that allows you to create SPK large displacement. Wing device hydrofoils containing hydrodynamic bearing surface rigidly attached by struts to the hull, and this hydrodynamic surface is divided into two similar in size to the upper and lower bearing surface rigidly connected to the swing of the internal vertical posts with education in a constructive attitude bezriskovoj farm, characterized in that the distance between the upper and lower bearing surfaces is 0.3 - 1.5 chord vertically and 0 to 1.5 chord horizontally with the possible removal of the bottom surface in the fore or aft relative to the upper.
