The invention relates to the field of modeling, mainly small commercial ships, such as boats, motor boats, scooters.

Known to the hull of a vessel containing a waterproof wall is coated with the waterline, which separates it on the surface and underwater parts underwater wings with holders [1].

The object of the invention is to increase the movement rate of small motor boats.

The technical result of solving the task is achieved in that in the case of a vessel containing a waterproof wall is coated with the waterline, which separates it on the surface and underwater parts underwater wings with the holders, on a straight section of wall on each side installed, at least one located at an angle with respect to the waterline, underwater wing with the possibility of vertical movement from an underwater position in the surface and back. Holders attached to the wall above-water and underwater parts and have the screw mounted rotatably, wherein the screw is provided with a nut, carrier underwater wing. Scuba wing is provided with at least one roller adjacent to the wall. Scuba wing bottom is provided with at least one longitudinally disposed rib. Scuba wing has the shape of a rectangular/trapezoidal/semi-oval.

Fig. 1 shows a housing to�tera, on the side wall of which is movably mounted to the underwater wing; Fig. 2 - view of Fig. 1 from above; Fig. 3 shows a fragment of a wall with a movable underwater wing.

The hull, for example, crew boat (Fig. 1 and 2), contains a waterproof wall 1 with the conventionally applied waterline W, separating it (the wall) on surface 2 and 3 underwater parts. Above-water and underwater parts of the wall on a straight section attached, respectively, the holders 4 and 5, with a common screw 6 is mounted rotatably. The screw is provided with a nut 7, the bearing flat underwater wing 8. The nut scuba wing is installed at an angle of α=2 to 12° in relation to the waterline (the angle α formed by the intersection of the X axis lying in the plane of the underwater wing, with the waterline W at point O). Screw and nut form a screw connection, providing an underwater wing for vertical movement from an underwater position in the surface and back. This wing can be in three positions: under water; surface water; above the water surface. Underwater wing (Fig. 3) is provided with at least one rotating roller 9 adjacent to the wall. Scuba wing may have a rectangular shape with rounded corners (Fig. 2 and 3), the shape of an isosceles or oblique trapezoidal or semi-oval (not shown). Bottom underwater glider can be equipped with �ne or more longitudinally spaced ribs 10.

From water resistant corrosion materials are manufactured model, the experimental model of the housing of small motorized vessel having a wall 1 with a deposited waterline W (Fig. 1), separating it on surface 2 and 3 underwater parts. With each side of the vessel to the wall on a straight section of it above and below the waterline is attached (soldered, welded, glued) to the holders 4 and 5 screw 6 having a nut 7. Underwater wings 8 in the form of a rectangle (Fig. 2), with equal or unequal legs of a trapezoid or semi-oval is made from a sheet material (metal, plastic), by stamping, mechanical or laser cutting. The sharp corners of the product scroogled, sharpen edges. Scuba wing supply at least one rotating rubber roller 9 and a longitudinally disposed rib 10 (Fig. 3).

Underwater wings attach directly to the nut with a tilt with respect to the waterline at the angle α=2-12°, for example, α=8° (the angle α formed by the intersection of the X axis lying in the plane of the underwater wing, with the waterline W at point O). It is possible to manufacture, for example, by the method of precision casting nut with a wing. By rotating the screw on manual or mechanical actuator, worm gear, bevel gear (not shown) scuba wing is movable vertically from an underwater position in surface and clicks�TNO. The number, shape, size hydrofoil depend on the speed of the vessel, its capacity, hull.

When you move the model, the experimental sample of a small motor vessel in the waters of the rivers, reservoirs, lakes submerged wings create a lifting force is able to increase its body relative to the water surface. When the location of the wings on the surface and above the surface of the waters arise, respectively, the effects of slip (gliding) and ekranoplane (due to the formation of the "air cushion" between the wing and the surface waters). In all cases decreases the hydrodynamic resistance of the hull oncoming water flow, increases the movement rate of the vessel. Rotating rollers exclude "scratching" underwater wing wall of the housing. The ribs are installed from the bottom hydrofoil, reduce the water flow in lateral directions. The hydraulic resistance of the screw and holder, situated (located) below the waterline, do not have a significant effect on the propulsion of the vessel. The invention improves the performance of small motor boats.
