Definitions

  • the invention relates to shipbuilding, in particular to motor boats, and in particular to inflatable motor boats with an inflatable bottom having high fast-moving qualities, good stability and a small circulation radius.
  • the rescue services used by ships in emergency situations are widely used in inflatable motor boats, which, in comparison with ships with a rigid hull, have obvious advantages: in the transported position they occupy very little space and do not require specially equipped premises for permanent storage and launching; when quickly delivered to the place of use, for example, by helicopter, they can, if necessary, be quickly deployed and launched, including by self-inflating; at the end of the rescue operation, they can also be quickly rolled up and delivered to the place of permanent storage.
  • a number of stringent requirements are imposed on inflatable ships.
  • vessels should have a small circulation radius, which allows them to maneuver well in the channels of small rivers or river channels, quickly evading various water obstacles (shallows, small islands, flooded vessels, etc.).
  • a motor boat with inflatable sides is known (see utility model of the Russian Federation .4 ° 170, MKI: B63B5 / 24, 1993), including a hull with a rigid profiled bottom, transom and inflatable sides forming an open loop. Due to the rigid profiled bottom, the boat has high hydrodynamic properties, allowing to provide high-speed characteristics of the boat due to the quick exit for planing.
  • the main disadvantages of the known motor boat are, firstly, the significant weight and dimensions of the rigid profiled bottom in the transported position. Secondly, the assembly of a well-known motor boat is rather laborious, and the boat itself does not always provide repeated tightness of the cockpit after repeated disassembly.
  • a well-known motor inflatable boat (see utility model of the Russian Federation M ° 6549, MKI V63V7 / 08, 1998), including an open contour of the A-shaped sides in plan, transom, elastic bottom attached to the sides, collapsible flooring, as well as installed between the elastic bottom and collapsible flooring, an inflatable keel in the form of a balloon, consisting of two truncated cones connected over a wide base.
  • the advantage of the famous inflatable boat is the presence of an inflatable keel, which gives the bottom a V-shape and improves the speed characteristics of the boat.
  • the main disadvantage of the known motor boat is that the boat contains a collapsible floor installed on top of the inflatable keel, which not only increases the weight of the boat in the transported position, but also complicates the process of deploying the boat.
  • Known motor inflatable boat see RF patent N ° 2237593, MKI B63B7 / 08,
  • the main disadvantage of the known inflatable motor boat is that the boat has a keel channel with smooth transverse transitions that do not create sharp longitudinal faces (protruding cheekbones), which are important for making a small circulation radius. Having developed high speed, such a boat is not capable of making sharp turns, which means it can also maneuver well. Therefore, the specified boat, for safety, can only move quickly on large water open spaces without obstacles, which significantly limits its application.
  • a motor inflatable boat includes an open contour of the sides of the A-shaped plan in plan, an elastic inflatable bottom of a keel-shaped form, attached to the sides in their lower part and consisting of the lower and upper parts of the elastic material, interconnected around the perimeter and divided inside into longitudinal sections by sections, as well as a transom installed in the stern of the boat on an inflatable bottom.
  • the advantage of the boat, in addition to its quick deployment, is the presence of transom plates installed behind the transom, which contribute to a faster exit of the boat for gliding.
  • the main disadvantage of the known motor boat is the location of the transom installed in the stern of the boat on the inflatable bottom and leading to the emergence of turbulent water turbulence. This is due to the fact that the inflatable bottom ends with a rounding, flowing around which the water jets create turbulences, thereby disrupting the laminar flow around the hull of the boat, which increases its resistance to movement, and, therefore, leads to a decrease in speed or increase fuel consumption, thereby reducing its performance. Even equipping a boat with transom plates connecting the transom to the sides only partially solves this problem by reducing turbulent water. turbulence at the sides of the boat. In the central part of the transom and near the engine, there is no laminar flow of water.
  • the basis of the invention is the task of improving the performance of a motor boat by eliminating turbulent eddies of water jets behind an inflatable bottom.
  • the indicated problem in a motor inflatable boat including an open contour of the A-shaped sides of the plane, a transom and a keel-shaped inflatable bottom attached to the sides in their lower part, is solved by the fact that on the aft part of the inflatable bottom on each side of the diametrical plane and parallel to it, a symmetrical number of stabilizer pads was installed, so that their ends directed toward the stern of the boat reach the edge of the transom or extend beyond the transom.
  • the indicated arrangement of stabilizer pads on the inflatable bottom makes it possible to improve the performance of an inflatable motor boat by properly organizing the flow of the bottom with water jets, thereby eliminating the formation of turbulent water turbulences behind the boat transom.
  • the height of the used stabilizer pads can be made different. Moreover, along its length, the stabilizer pad can be made of the same height or with its decrease towards the bow of the boat.
  • the number of stabilizer pads installed on the inflatable bottom is determined by the step of their installation (dense or rarefied, uniform or uneven) and is set by the required high-speed qualities of the boat and the required circulation radius. When installing more stabilizer pads, the circulation radius decreases.
  • the stabilizer pad can be made in the form of a segment of a U-shaped or U-shaped profile made of rubber, plastic or metal, fixed by gluing and / or sewing to the bottom.

Abstract

L'invention concerne le génie naval et notamment les canots à moteur et plus particulièrement les canots à fond gonflable possédant de bonnes qualités en termes de vitesse et de stabilité et un faible rayon de rotation. L'invention porte sur un canot gonflable possédant un contour des bords non clos en forme de A, un tableau et un fond gonflable en forme de carène qui est relié aux bords dans leur partie inférieure. La nouveauté consiste en ce que sur la partie poupe du fond gonflable, de chaque côté du fond diamétral et parallèlement à celui-ci, comporte un nombre symétrique de stabilisateurs en applique montés de manière à ce que leurs bouts orientés vers la poupe du canot arrivent jusqu'au bord du tableau ou dépassent hors de ce dernier.
