Description

The solution relates to small-sized shipbuilding, in particular, to inflatable hull vessels, mainly to tourist, pleasure, sports and for other purposes motor, rowing or sailing vessels.

Known inflatable motor small boats have a general construction principle.

A U-shaped inflatable hull, enclosed in a stern by a transom, and an inflatable bottom connected along the perimeter to the lower part of the hull. The inflatable hull, as a rule, occupies 1/3 of the height of the entire vessel. Inflatable bottoms come in different types, for example, flat, keel, catamaran type, trimaran type.

There are ships with flat contours of the bottom. Such vessels have the smallest draft and higher carrying capacity compared to other vessels.

For the vast majority of vessels, the classic contours of the bottom are keel bottoms, where in the center of the longitudinal axial bottom there is a ledge with a pronounced angle, which is set by the ship designer. Thanks to the keel, the bow of the vessel softer enters the wave and has stable directional stability.

Catamarans are characterized in that they have two floating formations on the bottom, which are parallel to each other and equidistant from the longitudinal axial bottom relative to the right and left sides. The bottom of the catamarans is flat, and when a set of speeds along the bottom of the vessel, a lifting force is generated and a planning effect occurs, the vessel rises, the mass of the vessel decreases and it glides over the water on floating formations (skegs). Catamarans have good speed characteristics, excellent straightness of the course, on-board stability and controllability in turns, there is no vessel roll. Catamaran type vessels are often used in sports competitions, at home, for high-speed walks.

Trimarans have a catamaran design, only one skeg is installed along the longitudinal central axial. Trimarans can carry more weight, but lose to catamarans in speed.

A patent of the Russian Federation for utility model No. 99763 (filed July 1, 2010, published November 27, 2010) is known, where the role of skegs is played by inflatable balloons, whether or not closed, which are interconnected by a power frame, and small floats are attached to the main inflatable balloons to form a planing surface.

Known RF patent for utility model No. 60058 (filed July 13, 2006, published January 10, 2007). The inflatable boat according to patent No. 60058 contains a U-shaped hull formed by inflatable sides, an inflatable bottom and a rigid transom, the bottom is made with the formation of plane-parallel surfaces of the deck and its keel part, and along the cylinders of each side of the boat hull from the bottom there are additionally installed at least one inflatable balloon enclosed in a shell fixed to the sides to form a skeg profile, wherein at least one elastic profile is installed longitudinally on the lower part of the shell. The keel part of the bottom of the boat is made longitudinally profiled. The skeg shell on the stern of the boat is open. The technical result of the utility model is the improvement of seaworthiness, namely the improvement of operational characteristics.

There is a patent of the Russian Federation for utility model No. 148315 (filed April 4, 2014, published December 10, 2014) in which the width of the skeleton sole is adjusted by means of the skeg cylinder, in which a partition is installed longitudinally, which fixes the height of the skeg cylinder, and the width of two lobes formed by the partition a single cylinder is set depending on the required width of the sole of the skeg.

This patent is the closest technical solution relative to the claimed by the number of common features.

However, the above analogues and the prototype have a number of limitations, such as an increase in weight due to the presence of additional elements connecting to the bottom, such as elements such as skegs, the high cost of finished products.

The proposed design of the vessel has sufficient technical simplicity of forming various contours of the bottom, cheapening the manufacturing process, increasing the speed of assembly and reducing the weight of the vessel. These advantages over the prototype are the technical result of the proposed solution.

The applicant has conducted a patent search on this topic. He showed that the proposed combination of essential features was not found. Therefore, this invention can be considered a new invention.

The essence of the invention and its practical performance is illustrated by the drawings and the following description.

A two-hull inflatable small boat formed by inflatable sides and an inflatable bottom is characterized by the fact that the channel shape of the lower part of the hull is defined by partitions of different heights, low partitions are set from the center to the edges of the hull plane, high partitions are along the edges, and there are significantly fewer low partitions creating a hydrochannel while the channel shape of the lower part of the housing may have a non-through channel, for which the low partitions can have a variable height.

The vessel is characterized in that the partitions along the transverse section are equal in height or have a uniformly decreasing height from the longitudinal central axial, or decreasing height relative to the longitudinal central axial, are wing-shaped, or cone-shaped, or rectangular in shape.

The vessel is characterized by the fact that the inflatable bottom in the stern ends with a transverse straight cut or continues in the stern behind the transom with an armhole along the central longitudinal axial axis for installing the motor, and in the latter case it is formed by the cut of the bottom and partitions, which are long in the required places of the vessel.

The vessel is also characterized by the fact that between the upper and lower hulls on the right and left side, in the places of their connection, channels are formed that serve as ballast tanks equipped with automatic or fixed drain water valves, or ballast tanks are installed in the necessary places of the vessel.

This application proposes (FIG. 1, FIG. 2) a small hull small vessel 1, consisting of an upper inflatable hull, for example, a U-shaped form 2 and a second lower inflatable hull 3 having an upper part flat and a lower part forming the shape of the bottom 8 , for example, flat, keeled, catamaran, trimaran, channel.

In the two-hull small vessel (FIG. 1), the U-shaped inflatable upper hull 2 and the lower hull 3 are connected to each other along the perimeter along the line of coincidence of the contact points (connection line) 4. The upper hull (FIG. 2) for the entire inflatable height 9 serves the sides of the vessel and forms the area of the cockpit, and the lower hull 3 forms the plane of the deck 10 of the vessel and the contours of the bottom 11, while varying the thickness and shape depending on the configuration of the bottom. If the vessel is motor (FIG. 1), the U-shaped inflatable upper hull in the stern is closed by a transom 7, if the vessel is a rowing, U-shaped inflatable upper hull in the stern is closed by an inflatable element 6, if the vessel is a sail, U-shaped inflatable upper hull in the stern may be open (position 5). A rowing vessel can be equipped with a mounted transom for installing a motor.

A two-hull small vessel (FIG. 4) may have an open upper hull in the bow. On the lower inflatable hull 3, two inflatable balloons 21, which are the sides of the vessel, are symmetrically fixed along the connection line 4 of the two hulls at the edges of the longitudinal axial 23. The nasal end 22 is the lower body of its nose. In the stern, the vessel may have a transom, a closed inflatable part or an open end.

The lower part of the body (FIG. 2) may have a bottom 8, with a flat shape, keel shape, catamaran shape, trimaran shape, channel shape.

The flat shape of the bottom (FIG. 2) is created due to two planes - upper 29 and lower 30 and partitions 12 having the same height and shape (FIG. 5) in the places of formation of the plane. Partitions are fixed to the lower and upper inner surface of the lower part of the housing.

The keel of the lower part of the body (FIG. 2) is formed by partitions 12 of different heights and shapes (FIG. 5), mounted on the upper and lower surface of the body, the height and shape of the partitions sets the keel of the bottom. Keeled can also be formed (FIG. 6) due to the cut of two halves 25 of elastic material of the type of two sinusoids 26, connected together along a sinusoidal line 27, creating a convex keel 28 along the longitudinal axial on the bottom of the lower hull of the vessel, while the partitions can be the same in height . Keeled can be set by combining two technical structures - partitions 12, forming keeled and cut two halves 25 of elastic material like two sinusoids 26, connected together, creating a convex keel 28 along the longitudinal axial on the bottom of the lower hull.

The lower part of the hull may have a catamaran bottom shape (FIG. 2) due to the convex formations 13 (skegs) located parallel to each other and equidistant from the longitudinal axial bottom to the right and left side. To create convex formations between two surfaces of the lower part of the hull, partitions are fixed along the longitudinal axis of the hull of the vessel, which have different heights. Where there should be a high part for the formation of the base of the skegs, high partitions 12 are fixed, which are much higher - to create the necessary air intake height. Partitions are located symmetrically relative to the longitudinal axial from the right and left sides, and low partitions 12 are fixed symmetrically with respect to the longitudinal axial axis. Thus, the height of the skegs and the width of the planning plane are formed. The width of the skeleton sole 14 depends on the number of symmetrical high partitions, and the aerodynamic surface, contributing to the formation of air flow and lifting force under the bottom of the vessel, is created due to the number of low partitions 12 forming the planning plane 15.

The trimaranic shape of the bottom of the bottom (FIG. 2) is no different from the catamaran type of bottom shape, except that along the central axial high partitions 12 are fixed, which form the base of the central skeg 16. The central skeg can be formed (FIG. 6) due to the cut two halves of elastic material 25 in the type of two sinusoids 26 connected together along a sinusoidal line 27, creating a convex keel 28 along the longitudinal axial on the bottom of the lower hull of the vessel. The central skeg (FIG. 2) can be defined by a combination of two technical structures — partitions 12, which form the central skeg 16 and the cut (FIG. 6) of two halves of elastic material 25 in the form of two sinusoids 26 connected together to create the sole of the central skeg 16 along the longitudinal axial on the bottom of the lower hull. The Central skeg (FIG. 2) can be formed by attaching to the bottom along the longitudinal axial inflatable balloon 33.

The channel shape of the lower part of the housing (FIG. 2) is set on the bottom of the housing by high partitions 12 from the edges to the center. At that, low partitions 12 are much smaller than in the catamaran design, and they do not create an air channel, but a hydrochannel 17, which forms a stable water flow for the operation of the water intake of the boat JET jet engine, creating a strong stream of water behind the vessel that sets its movement. The channel shape of the lower part of the housing (FIG. 2) may have a non-through channel, for this low partitions 12 may have (FIG. 5) a variable height 31.

Partitions 12 (FIG. 2), depending on the need, along the transverse section can be equal in height or have a uniformly decreasing height from the longitudinal central axial, or decreasing height to the longitudinal central axial. This is especially necessary when the skegs are formed (FIG. 2), since the plane of the soles of the skeg 14, depending on the design, may not be parallel to the water plane, but have a tilt angle longitudinal to the movement. Partitions 12 (FIG. 5) can be pterygoid or have a bending radius to the bow, or have a negative angle 24 in the stern, which forms the angle of resistance to movement of the vessel, contributing to the normal trim on the stern, or be cone-shaped, or rectangular in shape from the design of a small vessel.

The lower body may have a different design in the aft. For example, (FIG. 3) in the aft, the bottom can end with a transverse straight cut 18 or have a continuation in the stern behind the transom 19 with an armhole 20 along the central longitudinal axial axis for mounting the motor.

Between the upper and lower hull (FIG. 2) on the right and left side, at the points of their connection, channels can be formed that can be used for ballast tanks 32 equipped with automatic or fixed drain water valves. Or (FIG. 1) ballast tanks 32, which can be installed in the necessary places in accordance with the design of the vessel.

Made (assembled) of the proposed vessel 1 as follows.

First, separately according to known technology, an upper inflatable body 2 and a second lower inflatable body 3 are obtained, which has an upper part flat and a lower part forming the shape of the bottom 8, for example, flat, keeled, catamaran, trimaran, channel.

Then, the inflatable upper hull 2 and the lower hull 3 are connected to each other along the perimeter along the line of coincidence of the contact points (connection line) 4, using technology, for example, gluing or welding, obtaining a two-hull small vessel 1.

Depending on the design tasks, the bottom 8 and the corresponding partitions 12 of various shapes are performed.

Important in technology is that the bottom is not built into the container, but is attached (glued or welded) from below. The novelty of the proposed design lies in the fact that the two-hull inflatable vessel opens up the possibility of constructing more technologically advanced bottom contours, since the designer can fully realize the planned contours of the bottom, having a single area of the lower part of the lower hull, which is not trimmed with cylinders, as in a standard inflatable ship, and there is no space limitation for the formation of various contours of the bottom with the installation of various shapes of partitions in the lower part of the inflatable body.

The advantage of this design is the technical simplicity of forming various contours of the bottom, a significant reduction in weight due to the absence of additional elements for attaching to the bottom, such as skegs, cheaper manufacturing process, increased assembly speed, reduced cost of finished products.
