Definitions
- the invention relates to shipbuilding and can be used in the construction and modernization of marine high-speed single-hull motor vessels, which use a single displacement narrow wave-piercing hull.
- the main drawback of the narrow hull is its low stability - the long narrow hull easily falls on the starboard and left sides during its evolution and under the influence of waves.
- An additional drawback is the increased requirements for the quality of the submerged surface - with its relatively large wetted surface and thus, with tangible frictional force.
- the general principle of gliding skiing is to create at medium and high speeds the lifting force acting on a moving vessel when the hull partially or completely rises above the water surface. With a significant reduction in the area of contact of the housing with water, and, consequently, a decrease in hydrodynamic resistance to movement, this allows a higher speed to be developed.
- the lifting force created by lightly loaded gliding skis with supports of small displacement allows us to ensure the stability of the movement of the only wave-piercing displacement hull of the vessel (while moving in the displacement mode) and to ensure high seaworthiness of the structure.
- gliding skis The use of gliding skis is known from the following solutions, for example, from RF patents 144285, 2034736, 2211167, 81695, and 54353. But the known solutions relate to fully gliding hulls - namely, to hulls of high-speed vessels moving in a non-displacement mode when 100% of the weight the vessel is displaced above the water surface using the appropriate hull contours and engine power.
- the planing body has known disadvantages - since the body is practically has support of its weight on the water surface, at the same time it moves at a significant speed, a meeting with the wave causes the bow of the vessel to be thrown up and the subsequent “take-off” of the entire structure above the water surface, and also (if there is a side wave) to a significant side buildup on the move .
- Existing solutions are aimed at reducing the disadvantages of planing buildings and improving their characteristics.
- Patent 2211167 The principle of the hull with sharp-edged contours, with a breakwater ski is disclosed. This design in planing mode displaces 100% of the weight of the vessel above the water surface. The stroke in the displacement wave penetration mode, this design does not provide.
- Patent 54353 The principle of operation of a planing body with sharp-pointed contours and with a bow-breaker nasal ski is disclosed. This design in planing mode displaces 100% of the weight of the vessel above the water surface. The stroke in the displacement wave penetration mode, this design does not provide.
- the claimed solution allows the use of a single displacement narrow wave-piercing hull in the design of single-hull motor vessels, ensuring the achievement of a technical result, consisting in: - stable controlled motion of a single-hull motor vessel in the mode of wave penetration - i.e. in the displacement mode of small wave / hydrodynamic resistance, while ensuring efficient damping of the energy of the broken wave;
- the claimed stabilized hull used on a marine high-speed single-hull motor vessel, provides, in comparison with the modern level of technology (single-hull motor vessels):
- the stabilized hull of a single-hull motor vessel is characterized in that the hull with a total width of not more than 50% of its length, which is in its lower part
- the ratio of the length of the waterline to the width of the waterline of the narrow section is at least 7 times, with a displacement of the narrow section corresponding to more than 50%, but less than 80% of the total curb weight of the vessel,
- - also includes two longitudinally oriented symmetrical relative to the diametrical plane of the vessel supports located on the lower surface of the hull at the maximum width of the hull, with respect to the length of the hull, the location of the supports can be either closer to the stern or to the middle or bow of the hull,
- the supports in the lower part are made with planing skis of small displacement, creating a lifting force while sailing the vessel, counteracting the weight of the hull and reducing its draft, thereby ensuring the lifting of the supports above the water surface,
- the length of the planing skis is not less than 50% of the length of the hull
- planing skis are made with planing contours of type "V",
- FIG. 1 shows a general view of the hull of a single-hull motor vessel 1 (the motor is not shown in the drawings), where dimming 2a marks its wetted surface when moving at medium and high speeds.
- the main elements are the upper part of the body 3, the wave-piercing displacement narrow section 4, the right 6 and left 7 support of small displacement, the right 8 and left 9 gliding skis of small displacement, the front high wave-piercing shaft 10.
- the narrow section 4 (Fig. 1) is made long, narrow, with high contours of small wave / hydrodynamic resistance, with a relative lengthening of the waterline L / W WL of at least 7 times - thus providing a displacement mode of wave penetration, as well as laminar flow around the entire flow path, ensuring the cutting and passage of the wave along a narrow section with minimal impact on the speed of the vessel.
- High wave piercing stem 10 allows you to cut the wave with minimal loss of speed.
- the heavy equipment of the ship and the supplies of water and fuel (if necessary) are located in the lower part of the narrow section 4 - thus minimizing the inertial moments of its weight during the evolution of the hull and lowering the center of gravity of the hull.
- the displacement of the narrow section 4 is related to the weight of the fully equipped ready-for-sailing vessel - including the crew, equipment, water and fuel supplies (if necessary), etc. - in the range of 50% -80%, thus in the absence of progress - for example, at the berth in the port or at the anchorage, the narrow section 4 and the supports with planing skis are completely submerged under the weight of the vessel.
- FIG. 2 shows a wetted surface 26 with no stroke.
- Symmetrical right 6 and left 7 supports are located at the same distance from the diametrical plane of the vessel at the maximum width of the hull, in its lower part.
- the supports are thin plates of structural strength sufficient for reliable fastening and ensuring the operation of planing skis in all modes, the supports are made, for example, of metal or composite materials.
- the supports have an installation angle relative to the diametrical plane of the vessel (Fig. 1 shows an angle of 10 degrees) necessary to ensure more efficient operation of planing skis to counter the swing of the hull on the waves.
- FIG. 1 shows the location of the supports along in relation to the length of the hull closer to the stern part, it is also possible to arrange the supports closer to the middle, or to the front parts of the hull.
- the supports in their lower part are made with planing skis 8 and 9 of small displacement, located on the left and right side on the width of the hull, or protruding beyond its dimensions, made, for example, of metal or composite materials.
- Bottom planing skis are made with planing contours of type "V".
- planing skis In the front part, planing skis have an angle of inclination upwards, thus, planing skis on the go create a lifting force that counteracts the weight of the body and reduces its draft.
- the lifting force of gliding skis 8 and 9 acts on the hull of the vessel, thereby providing a partial rise of the hull above the water surface - which leads to a decrease in the wetted surface of the narrow section 4 (see the change in wetted surface from "26" in Fig. 2 to "2a” on Fig. 1).
- the wetted surface of the narrow section 4 is reduced, and the hydrodynamic resistance to movement of the housing is accordingly reduced.
- the narrow shape of the supports b and 7 and their wide arrangement allow the formation of tunnel cavities 11 (see Fig. 1) between the narrow section 4 and each of the supports, where the cavities 11 minimize the wetted surface at the media boundary, and where effective damping takes place in the cavities 11 the energy of a broken stem and wave supports.
- the waves are broken by stem 10 and rolled under the hull of the vessel raised above the water surface, in the tunnel cavities 11, reducing the effect of wave impacts on the hull of the vessel.
- FIG. Figure 3 shows a view of a support with a gliding ski attached to it, and the same assembly is illustrated with sections of the view.
- this knot is essentially a thin-walled inverted T-shaped structure with a planing "V'-profile in its lower part, while the planing ski has an inclination angle upward in its front part.
- the support and the planing ski attached to it have no significant displacement, which allows them to be effectively used to counter the swinging of the hull on a wave on a motor drive.
- FIG. 4 shows an example of the passage of a wave by a body with a support and planing ski on a motor course.
- the relatively large length of the planing ski (more than 50% of the length of the vessel) allows it to lean on the crests of several medium-sized waves (see Fig. 4) while at the same time the small combined displacement of the support and ski does not allow them to "fly up” to the crest waves of larger than average size, effectively “breaking through” through such a crest. This reduces the effect of wave buildup on the hull - providing support for medium waves and stable passage of the high wave peak.
- a narrow section 4 displaces in the range of 50-80% of the weight of the vessel, while the required lifting power of planing skis is small, and amounts to 20-50% of the weight of the vessel.
- gliding skis when located on the width of the hull, provide effective resistance to ship buildup on the wave and, due to the small displacement of the supports and gliding skis, stable passage of the “peak” of the wave, this effect increases with increasing speed of the ship — that is, in this design solution, planing skis play a key role in stabilizing the course of the ship.
- the claimed stabilized body can be made, for example, of fiberglass, other composite materials, wood, metal, polyethylene, and combinations thereof, and / or other materials adopted in shipbuilding.
- the declared stabilized hull provides a combination of using a single narrow displacement section with a relative elongation of the L / W WL waterline of 7 or more times (and, accordingly, taking advantage of low wave / hydrodynamic resistance, high seaworthiness and stability), and also the time of an effective stabilization system (namely, counteraction to wave buildup) to ensure dynamic stability of the housing is better than that of modern single rpusnyh motor boats.
- the use of lightly loaded gliding skis creates additional lifting force that counteracts the weight of the hull and reduces its draft when forming the effective size of the tunnel cavities on the go, while the low displacement of the gliding skis and supports ensures a stable passage of the peak wave by the hull.
