Description

Technology area

The stated solution relates to the field of shipbuilding, namely to the structures of motor boats.

State of the art

Known solution RU 88642 U1 "INFLATABLE MOTOR COMPOSITE BOAT", containing a rigid hull, consisting of a deck, a bottom with a power set, inflatable U-sides and a device for lifting and lowering the boat.

The disadvantage of the known solution can be considered that inflatable boards, which can be damaged by collision or collision with sharp objects, require additional care and attention during operation. Another disadvantage is the impossibility of installing the wheelhouse or the windshield, because of the impossibility of fastening to the inflatable sides, or the wheelhouse can be installed, but only on a hard bottom, which significantly reduces the size of the installed wheelhouse.

Known boats in which the sides are made of rigid material, and to enhance rigidity and maintain shape, having a significant number of bulkheads, both longitudinal and transverse, which increases the weight of the structure.

Disclosure of essence

The task to which the declared solution is directed is the development of the design of a motor boat, with rigid sides, allowing to fix the necessary equipment, including the deckhouse or windshield and other elements, while maintaining light weight and driving performance, as well as having high reliability and allow you to perform any shape of the side, including in the profile section, without losing rigidity.

The claimed solution allows to solve the set tasks due to a simple design of a similar design of an inflatable motor composite boat, but with the execution of inflatable boards from light, thin, rigid material with gas injected into the inner space. The injected gas makes the board rigid and makes it possible not to use frame bulkheads, which reduces the weight of the boat without losing rigidity.

The declared motor boat (1) has a rigid bottom (1.2), an open contour of the sides repeating the U-shape (1.1), a transom (1.3) for the power plant.

Unlike analogs, the boards (1.1) are made of light, thin, rigid material. The inner space of the sides (1.1) is filled with pressurized gas. The inboard pressure must be higher than atmospheric pressure and provide structural rigidity.

The preferred inboard pressure is in the range of 0.5-3 atm.

Filling with gas under pressure makes it possible to make sides of any shape both along the outer contour and in the profile section. So the sides can have bends, turns, thickenings, niches, etc., without reducing the rigidity and can be made on the basis of the U-shape of FIG. 1, i.e. be integral and follow the contour of the boat, or from segments repeating in the assembly the U-shape of FIG. 3, or be made on the basis of the I-shape and located along the edges of the boat of FIG. four.

As the material from which the sides (1.1) are made, aluminum, aluminum-magnesium alloys, dural alloys, fiberglass, kevlar, carbon fiber, carbon, steel can be used.

This design of the side makes the boat light and reliable, not afraid of punctures when hitting or colliding with sharp objects, and also allows you to install, with emphasis on the sides, elements that require rigid support during operation, for example, the wheelhouse and / or deck, and / or the wind glass, and / or fasteners for oars, and / or handrails, and / or awning, etc.

Filling with gas increases the rigidity of the sides and the hull of the boat as a whole, increases the carrying capacity and buoyancy.

In the particular case of the design to strengthen the structure, in the places where elements creating a significant load are installed on the sides, at least one transverse bulkhead (1.1.1) of Fig. 1 can be installed inside the sides (1.1). 2 to form more than one chamber. Bulkheads (1.1.1) may have at least one opening for communication of cameras.

As a result, the claimed solution is lightweight, resistant to damage and allows the installation of the necessary elements without loss of functionality and space.

Implementation of the invention

A motor boat (1) is made with a rigid bottom (1.2), a transom (1.3) for the power plant, an open contour of U-shaped sides (1.1) or from segments or I-shaped, and made of light, thin, rigid material ... The inner space of the sides (1.1) is filled with gas at a pressure of 0.5-3 atm.

In the particular case of the side board in the place (s) of installation on board the element (s) creating (their) significant load, for example, the windscreen attachment points, are made with at least one transverse bulkhead (1.1.1) with the formation of more than one chamber. The bulkhead (1.1.1) may have at least one opening for communication of cameras.

In the particular case of execution, the necessary equipment is installed on the boat during operation and requires rigid support and fastening for the sides, for example, they install: the wheelhouse and / or deck, and / or windshield, and / or fasteners for oars, and / or handrails, and / or awning.

The finished boat is launched and operated in the usual way.

In the particular case of execution during operation, the necessary equipment is installed on the boat and requires rigid support and fastening for the sides, for example, they install: the wheelhouse and / or deck, and / or windshield, and / or fasteners for oars, and / or handrails, and / or awning. After which the boat is launched and operated in the usual way.
