Description

An external storage compartment for a miniature submarine

technical field

The invention relates to a submarine, in particular to a multi-functional, long-distance, and externally-mounted detachable external storehouse for ultra-miniature submarines.

Background technique

The most powerful at sea is the aircraft carrier battle group, which is generally equipped with 1 cruiser, 1 destroyer, 1 frigate, and 1 attack nuclear submarine. In terms of defense, the defense range of the aircraft carrier battle group is about 500 nautical miles; And the near defense area, with an early warning aircraft, an electronic warfare aircraft, a reconnaissance aircraft, and helicopters performing anti-submarine missions;

It can attack you more than 700 kilometers away from the defense zone, but you are beyond reach;

The seabed is relatively hidden. Submarines may break through defense lines or ambush aircraft carriers. Submarine attack weapons are mainly torpedoes. Take the most advanced Ukrainian Blizzard torpedo as an example. Its speed is very fast, but its range is only 6-12 kilometers. They are Russian 65-73 and 65-76 large torpedoes, and their range is only 100 kilometers, that is to say, they have to go deep into its near defense zone to launch an attack. Also, if a submarine wants to attack a target, it must first turn on the active sonar to lock the target, but in this way The position of the submarine itself is completely exposed, and it is even more difficult to escape from the close defense zone;

The self-noise of a submarine is mainly related to its speed and tonnage. The greater the speed, the greater the self-noise; the larger the tonnage of the submarine, the larger its reflection area, and the farther and easier it is to be detected by the opponent's active sonar; the radiation noise intensity of the submarine The larger the value, the farther and easier it is to be discovered by the opponent's passive sonar.

Therefore, to deal with aircraft carrier battle groups, it is best to use manned ultra-miniature submarines with excellent concealment, low noise, large dive depth, and long range (at least more than 1,000 kilometers);

With the development of science and technology, unmanned submarines are widely used, but if unmanned submarines are too far away from the mother ship, they will not get information. Underwater communication is different from that in the air. Signals cannot be transmitted over long distances underwater; nor can they be automatically transmitted. Responsiveness; if constantly surfacing to receive information, it is easy to expose yourself;

It is best to be an ultra-miniature manned submarine of more than ten tons. When the thickness of the submarine hull is the same, the smaller the hull, the better the pressure resistance and concealment;

However, there are many problems to be solved in the design of weapons, a large number of batteries, various equipment, personnel operation and living space; the most reasonable and convenient solution is to hang some equipment externally, which reduces the load of the miniature submarine It also enriches the different equipment required by the miniature submarine, and can perform a variety of different tasks;

After long-term thinking and consulting a large amount of information, I finally designed a detachable external storage for miniature submarines.
