RU2319636C2 - Submersible boat - Google Patents

Abstract

FIELD: marine engineering; new types of sea-going submersible boats.

SUBSTANCE: proposed submersible boat has outer hull with ballast tank, storage battery and watertight buoyancy motor room, as well as fore and aft trim adjusting tanks. Submersible boat has two pressure watertight compartments (fore and aft compartments) which form constant buoyant volume of boat. Located in between watertight compartments is non-watertight changeable transportation module.

EFFECT: possibility of fast change of one kind of armament by another.

Description

The invention relates to marine technology, namely to its new class - submersible boats (PC).

There are well-known PCs of foreign companies: "Subskimmer" - Great Britain, MK-1 SSB - USA, SRC - Great Britain (railway station No. 10, 1998), as well as the design of the diving boat 1231 GMF "Dolphin" (railway station) . "Military Parade" No. 3, 1998) - analogues of the invention.

The main task of the created boats is the secretive delivery of divers (combat swimmers) and cargo (weapons) to the combat mission solution area.

Consider the design of submersible boats on the example of the project "Subskimmer-85" of the English company "Submarine Product Ltd" (m. Combat Craft, Sept./October, 1985) - a prototype.

PC "Subscimmer-85" is a lightweight planing boat with a rigid hull made of fiberglass and soft inflatable sides made of nylon fabric impregnated with polyurethane.

For movement in the above-water position, an outboard gasoline engine is used, closed by a waterproof casing, puffed out air, the pressure of which is automatically maintained.

For movement under water, two propeller-driven columns with electric motors are used, located in the bow of the boat and powered by a battery.

The boat can deliver 4-6 combat swimmers with cargo to the area of solving the problem. The movement speed in the surface position is about 20 knots, in the underwater position - up to 2.5 knots.

The boat has two ballast tanks and one equalizer. As ballast tanks, soft inflatable containers on the sides with end caps are used. The equalization tank is located in the middle of the boat and has a blowing system. The air pressure in it is maintained automatically and is equal to outboard. It provides immersion of the boat after filling the ballast tanks and maintaining zero buoyancy in the underwater position at different salinity of the water.

The SRC (Submersibl Recovery Craft) PC has a similar design, but it can carry a large payload. It can be equipped with a machine gun, 30 mm cannon or NUR for firing at coastal targets. The immersion depth of the PC is 27 m, the payload is 1270 kg.

The disadvantage of the existing submersible boats "Subscimmer" and SRC is a very limited list of tasks and the range of delivered weapons and cargo.

At the same time, there is a need for multi-purpose PCs that allow delivering goods such as:

- anchor and bottom sea mines;

- small torpedoes;

- cargo airtight containers;

- unguided rockets;

- groups of combat swimmers with underwater vehicles and without them.

In this case, the depth of immersion of the PC in some use cases can reach 100 or more meters.

This need cannot be realized within the framework of the design of existing PCs.

The objective of the invention is the creation of a multipurpose PC that allows you to quickly replace one type of weapon with another.

The problem was solved by equipping the PC with a permeable replaceable transport module (STM) located in the center of the PC and balanced by buoyancy with two durable dry PC compartments located in the bow and stern.

The drawing shows a layout diagram of a PC.

The proposed PC contains: feed differential equalization tank 1; engine compartment 2; compartment with removable transport module 3; crew cabin 4; nose differential equalization tank 5; ballast tank 6; battery 7.

Using a PC is as follows.

In the base, in compartment 3, a removable transport module is loaded, previously hung up to normal negative buoyancy. A more accurate sign and trim is made using trim-equalization tanks 1 and 5, with the ballast tank 6 filled. In this case, the large negative buoyancy of the permeable STM and the lightweight PC case is compensated by the strong dry sealed compartments 2 and 4, which make up the constant floating volume of the PC.

In the above-water position on the go of the PC, its weight is significantly reduced due to the purge of the ballast tank 6 and the discharge of water by gravity from the permeable STM. Thanks to this, the PC enters hydrofoil planing mode.

In the underwater position, the ballast tank 6 and STM 3 are filled with water, and the PC sign is close to zero due to differential equalization tanks 1 and 5. The PC is moved by the battery 7 and the propeller motor located in the engine compartment 2 on the same shaft with the diesel engine .

The use of the invention is possible both for military and civilian purposes, for example, for the quick delivery of divers and repair equipment to the accident site of an underwater pipeline.

Claims (1)

An immersion boat comprising a light hull with a ballast tank, a battery and a sealed dry engine compartment, as well as a bow and stern trim-equalization tanks, characterized in that it contains two durable sealed compartments (bow and stern), which make up the constant floating volume of the boat, between which hosts the permeable interchangeable transport module.
