Abstract

FIELD: transport.

SUBSTANCE: proposed hull comprises watertight wall with water line dividing said wall to surface and underwater parts. At least one foil is arranged at the wall straight section on every board and inclined to waterline to displace vertically from underwater position to surface position and vise versa. Every foil has gas-filled cylinder fitted at its end, its lift partially compensates for its weight in water.

Description

The invention relates to the field of modeling of civil vessels, mainly large cargo ships.

Known hull containing a waterproof wall with a waterline, dividing it into surface and underwater parts, hydrofoils [1].

The objective of the invention is to increase the propulsion of bulky cargo ships.

The technical result of the solution of the problem is achieved by the fact that in the hull of the vessel containing a waterproof wall with a waterline, dividing it into the surface and underwater parts, hydrofoils, at least one located on the wall section between the bow and stern sections from each side the hydrofoil inclined with respect to the waterline with the possibility of its rotation from the working state to the non-working one and vice versa. The underwater wing is made flat, attached to the wall on hinges, has a rotation limiter and an attachment element for a cable wound on a winch drum located in the above-water part. The hydrofoil has a gas-filled balloon at the end, whose lift partially compensates for its mass in the aquatic environment. The hydrofoils have the shape of an arcuate / rectangular / triangular / rhombus / trapezoid and are located one above the other / with an offset of one relative to the other.

In FIG. 1 shows the hull of a vessel for transporting bulk cargo with hydrofoils mounted on its wall between the bow and stern sections from each side (the first and second hydrofoil pairs along the vessel are located one above the other, the third pair with the displacement of one wing relative to the other) located oblique to the waterline, side view; in FIG. 2 is a view of FIG. 1 along A, where, on the starboard and starboard sides, the hydrofoils are, respectively, in working and non-working states; in FIG. 3 shows a fragment of the wall of the body with a hinged swivel underwater wing in the form of an isosceles trapezoid; in FIG. 4 shows diagrams of various forms of hydrofoils.

The hull of a cargo vessel, for example a vessel for transporting bulk cargo, contains a waterproof wall 1 with a conditionally applied water line W, dividing it into surface 2 and underwater 3 parts. Below the waterline from each side between the bow 4 and the stern 5 sections, flat hydrofoils 7 are mounted to the wall by hinges 6, located one above the other / with the displacement of one wing relative to the other (Fig. 1). On the wall of the hull, hydrofoils are located (installed) at an angle α = 2-12 ° with respect to the waterline (angle α is formed by the intersection of the X axis lying in the plane of the hydrofoil with the waterline W at point O). The hydrofoils can be in working and non-working states (Fig. 2) depending on the tension of the steel cables 8. The cable is clamped in one side of the hydrofoil by the fastening element 9, and on the other end is attached to the drum 10 of the winch 11 located in the surface of the hull (figure 3). Winches can be combined into a single system (not shown) for controlling the hydrofoil rotation. Instead of a cable, a round link chain can be used. Each hydrofoil has a rotation limiter 12. The hydrofoil can have a gas-filled cylinder 13 at the end, the lifting force of which partially compensates for it (the wings) in the aquatic environment. The hydrofoil can be arched (figure 4, a-d), rectangular (e, f), triangular (g, h), rhombus (i), trapezoid (j, k). A traverse (pivoting, retractable, folding) with a signal (color, light) beacon at the end indicating the boundary position of the underwater wings can be attached to the wall from each side of the hull in its surface part from above.

A model, an experimental sample of the ship’s hull, having a wall 1, with a water line W applied to it, dividing it into surface 2 and underwater 3 parts (FIG. 1 and 2) is made of water-resistant materials. From the sheet material (metal, plastic) are made (for example, by gas, laser, mechanical cutting, stamping, molding) hydrofoils 7. The planes of the hydrofoils are made even and smooth, the edges are rounded. The fabricated hydrofoils are installed (suspended) on the hull wall from each side on hinges 6, placing them between the bow 4 and the stern 5 sections with the X axis inclined with respect to the waterline at an angle α = 2-12 °, for example, α = 6 ° (Fig. . one). On the wall of the body hydrofoils are mounted one above the other or with the displacement of one wing relative to the other. At the same time, each hydrofoil is mounted rotatably from the working position to the idle (Fig. 2) by tensioning / loosening the cable 8. To perform the operation of turning the hydrofoil, the cable is clamped from one end by a fastening element 9, and attached to the drum 10 from the other end winch 11 (Fig. 3). The limiter 12 prevents the rotation of the hydrofoil above a predetermined (horizontal) operating position. To reduce the turning force of the underwater (metal) wing, a gas-filled cylinder 13 is fixed at its end, the lifting force of which partially compensates for its mass in the aqueous medium. An equivalent technical solution is to fill the balloon with ballast, for example lead shot, in the manufacture of a hydrofoil from a composite material whose density is less than the density of water. Form (figure 4, a-k), size, number of hydrofoils are selected depending on the carrying capacity and a given speed of movement of the model ship. To the hull wall in its above-water part from the top, a beam is attached with a signal beacon indicating, for example, an oncoming vessel, to the boundary position of the hydrofoils.

When moving a cargo vessel in the water area (sea, lake, large reservoir), hydrofoils in the working position create a lifting force that can slightly raise the hull relative to the water surface. In this case, the hydrodynamic resistance of the hull to the oncoming water flow decreases, and the propulsion of the vessel increases. In the case of a roll of the vessel, for example, when moving the bulk cargo, the hydrofoils are left in the working position on only one side (roll) of the hull, while its buoyancy is maintained. When loading / unloading a ship in port, hydrofoils translate (loosen the cable tension) to the inoperative position.

The invention increases the propulsion of the vessel.
