Description

Technical field

The technical solution relates to shipbuilding, in particular to inflatable boats with a low pressure inflatable bottom.

State of the art

It is known that the speed characteristics affect the movement of inflatable boats and depend, in particular, on the deadrise - the shape of the bottom of the boat, made in the form of an angle - dihedron along the entire length of the bottom. The deadrise noticeably weakens the force of the landing impact of the inflatable boat on the water, while slightly increasing the resistance of the water.

Known inflatable boat with a bottom in the form of a "gull wing" (RU 140473 U1 from 11/11/2013, class IPC B63B 7/00). An inflatable boat containing a side in the form of an inflatable U-shaped balloon, a transom installed in the stern of the boat, an inflatable bottom consisting of an upper flat bottom and a lower curved bottom attached to the lower part of the side, and an end part, while the upper and lower bottoms are made from an elastic material, where the upper and lower bottoms are interconnected by forming partitions, and the lower bottom in cross section and the lower edge of the end part of the bottom have the shape of a "gull wing".

The disadvantage of the technical solution, as practice shows, is a negative bulge in the end part of the bottom due to the fact that the air under pressure in the inflatable bottom tends to evenly occupy the entire volume. Moreover, if the partitions are symmetrical to each other, then the air is distributed evenly, which affects the shape of the "gull wing", in particular the end part of the inflatable boat, which negatively affects planing.

An inflatable elastic keel-shaped bottom is known (RUU1 dated 21.08.2014, class IPC B63B 7/08), as a means of creating a keel-shaped bottom, forming partitions are used, which are located inside the inflatable bottom, consisting of the lower and upper parts and are made of elastic of a sheet of material, the partitions forming the keel are wing-shaped and fixed through connecting elements on both sides of the axis of symmetry in the diametral plane to the inner surface of the lower and upper parts of the bottom and are interconnected along the edge of the free edge along the entire length, and the number of forming partitions is equal relative to the axis symmetry and as they move away from it, their height decreases, and the distance between the axis of symmetry and the corresponding partitions on both sides of the axis of symmetry is the same, characterized by the fact that on the upper part of the bottom in the diametrical plane the partitions are fixed symmetrically to each other, in the lower keel part of the plane of the bottoms and the partitions are fixed at a distance greater from each other than the upper part of the partitions is fixed relative to each other on the upper plane of the bottom, or the lower part of the partitions is fixed parallel to each other. The specified technical solution is taken as a prototype.

The disadvantage of the technical solution is that as you move away from the axis of symmetry of the bottom, the height of the forming partitions decreases, thereby stalling the water flow rests on the balloon, which leads to a decrease in speed characteristics and braking of the inflatable boat.

The objective of the technical solution is to develop the bottom of an inflatable boat with a "gull wing" shape, which provides increased controllability.

Disclosure of the essence of the technical solution

The technical problem is solved by manufacturing the bottom of an inflatable boat, made of an elastic sheet of material and including forming partitions, which are located inside the bottom itself, where the latter consists of a keel and a deck part, and characterized in that along the axis of symmetry in the diametrical plane to both a Y-shaped partition is added to the bottom parts, while the Y-shaped partition itself is cut out of an elastic material in two parts, where both parts are sewn, or glued, or welded together, and is attached to the deck part along the axis of symmetry, and on the keel part - receding from the axis of symmetry in different directions.

The specified technical solution provides a smooth ride during movement in rough water, due to increased deadrise, as well as more confident wave passage and directional stability.

Implementation of the technical solution

The technical solution is shown in Fig. 1-3, where an inflatable boat with a bottom is made of an elastic sheet of material and includes: a U-shaped balloon (1) representing an open U-shaped contour; inflatable bottom (2), which is a closed circuit, consisting of deck (5) and keel (4) parts, connected by forming partitions (8), transom (3) installed in the stern of the boat and serving to connect the U-shaped cylinder (1 ), the keel part (4) of the inflatable bottom, which consists of two curved parts interconnected; the deck part (5) of the inflatable bottom, which is a flat upper element. At the same time, all forming partitions (8) are built inside the bottom. And characterized in that along the axis of symmetry in the diametrical plane, a Y-shaped partition (6) is added to the keel (4) and deck (5) parts of the bottom.

The Y-shaped partition (6) is cut according to patterns of elastic material in two parts, which can be:

sewn with strong threads,

welded with a welding machine,

glued with PVC tapes.

At the same time, a Y-shaped shaping partition (6) is attached to the keel (4) part of the bottom, departing from the axis of symmetry in different directions, by a size approximately equal to the size of the height of the soma partition along its entire length, thereby forming an air channel (7), which increases the keel shape of the bottom (2) along its entire length, thereby increasing the control of the boat.

The proposed design, when moving an inflatable boat, cuts the water surface better and distributes water flows along the entire length of the bottom, which, in turn, improves speed characteristics and maneuverability, and also allows you to quickly enter the gliding mode.
