() The most obvious example is that mechanical computers were commonly installed on warships during this period. The fire control officer on the warship used an optical sight to obtain the enemy ship's speed, relative distance, target size, advance and other parameters.
, then manually input it into the mechanical computer, and then the computer calculates the design firing elements, and uses a wired telephone to notify the gunner to target and fire according to these firing elements.
On the basis of this mechanical computer, the Federal Research Institute added a large number of electron tubes and relays to replace some of the mechanical devices, and used the binary algebra algorithm invented by the British mathematician George Boole to increase the computer's calculation speed by dozens of
times, and realizes some automatic data input.
However, due to the addition of a large number of electron tubes and relays, this semi-electronic and semi-mechanical computer has become a bit large and consumes a lot of power and heat. It is not suitable for installation on small ships and can only be installed on small ships.
On ships with large spaces such as heavy cruisers and aircraft carriers.
With this semi-electronic computer and radar system, the King-class aircraft carrier can detect large surface ships 60 kilometers away, submarines sailing on the surface 10 kilometers away, and submarines 1 meter above the water 2,000 meters away.
Submarine periscope and snorkel.
Although this kind of radar system is easy to use, due to the lifespan and heat dissipation problems of the electron tube and magnetron, the current model of the "Lighthouse-1" shipborne radar has only a continuous power-on capacity of 3 hours, and the failure rate is relatively low.
High, so the main reconnaissance mission of the aircraft carrier formation is still completed by the carrier-based reconnaissance aircraft and the ocean-going submarines in the formation. Only in wartime or when the weather is bad and the reconnaissance aircraft cannot take off, the ship-based radar will be turned on 10 minutes apart.
hours, temporarily acting as the eyes of the fleet.
Speaking of submarines, this kind of underwater killer has always been the national treasure of the Federation. From the initial blocking of three ambush battles to the subsequent attacks on the combined fleets of the six countries, the Federation's submarines were invincible. Although in World War I,
The United Kingdom and Germany have also used submarines as a means of attack to varying degrees, but in today's world, the South China Sea Federation is still far ahead in terms of submarine technology.* w w w . s&nbsbsp;o m *
The development of federal submarines has gone through three levels and more than a dozen models, from the early "Big Yellow Fish-class" to the later "Tuna-class" to the "Shark-class" submarines currently in service. Currently, the federal navy's submarine force
, "big yellow croaker level" and "tuna level"
All submarines have been decommissioned and sealed. Only a small number of these two classes of submarines are still active in several submarine schools, serving as training equipment, or being modified into different types of scientific research submarines for various research institutes.
For marine, geological and survey purposes.
Since submarines have always been the national treasure of the federal government, Liu Fu has never agreed to sell any federal submarines or submarine-related technologies to foreign countries. Even after the start of World War I, he did not take advantage of the warring parties to become red.
He took the opportunity to sell the submarine at a high price. Because Liu Fu knew very well that not only would later generations of Chinese be good at the technical work of copycatting, but those Europeans would rely on their strong scientific and technological strength.
se.
Moreover, their R&D capabilities and research habits are even better than those of the Chinese. Once these submarines fall into the hands of European and American countries, their design ideas, special processes, material compositions, special equipment and other technologies will soon be studied by various countries.
If you understand it thoroughly, you may be able to draw inferences and invent more advanced and reasonable technologies.
By that time, the federation's submarines will completely lose their technological advantage and turn into a numerical disadvantage. For a country like the federation, which is composed of many islands, once the navy loses its advantage, and it is an Asian country that has just emerged.
, those European and American powers that have gained maritime superiority will quickly extend their claws to the federal federation and eat it.
Therefore, starting from the "Big Yellow Croaker" submarine, every decommissioned submarine has been sealed, and then dismantled and refurbished in proportion, leaving only a certain number of submarines so that they can be quickly converted into
service status to supplement the shortage in the number of active submarines.
Today, there are "Shark-class" submarines in service in the federal navy. The number is about 180. They are divided into three submarine groups and are stationed in Taiwan, Annan and Mindanao. With the addition of the East Indies to the federal territory,
, the number of submarines in these three submarine groups was already slightly insufficient, so the fourth-generation federal submarine "Orca-class" began to move from design drawings to the slipway.
The "Orca-class" submarine is the fourth-generation submarine of the Federation. It was basically successfully developed in 1913. However, due to the world's naval equipment at that time, the "Shark-class" submarine was enough to sink any main ship of any country.
Therefore, the "Orca-class" submarine was not approved for production, but the Naval Research Institute continued to improve the design.
After nearly five years of later improvements, the "Orca-class" submarine has been completely different from when it was first designed. Not only has a lot of new equipment been added, but the appearance and some more advanced manufacturing materials have also been changed.
The current "Orca-class" submarines are divided into two types: attack submarines and anti-submarines. The attack submarine refers to the design concept, which is a submarine that targets surface ships. Its level is designated as the "Orca-class"
"; The anti-submarine is a submarine designed by the Federal Research Institute to deal with possible battles between submarines in the future and targets enemy submarines. Its level is designated as the "Orca-class".
The "Orca-class" submarine has a standard displacement of 1,600 tons, a full load displacement of 1,990 tons, a length of 78 meters, a width of 8 meters, a water surface draft of 5.6 meters, and a double-hull structure. It is combined by two 8-cylinder diesel engines and two electric motors
Dual-shaft propulsion, providing 5400 horsepower on the water surface, with a maximum speed of 17 knots and a cruising speed of 10 knots
It can travel 11,000 nautical miles, provide 5,000 horsepower underwater, have a maximum speed of 21 knots, and a cruising capacity of 480 nautical miles; due to the use of a new secondary discharge battery pack, the "Orca-class" submarine can continuously rely on batteries to travel slowly underwater
More than 40 hours without surfacing greatly increases its threat.
In order to improve the submarine's survivability and stealth capabilities, the "Orca-class" attack submarine is also equipped with two silent electric motors, which can rely on batteries to provide 300 horsepower to the submarine and push the submarine underwater at a speed of 7 knots.
Navigation; This silent electric motor uses new materials and a new rotor pattern. When started, the noise and vibration are very small, allowing the submarine to be hidden in the background noise of the sea water, making it difficult to be detected by simple sonar equipment.
The "Orca-class" attack submarine is equipped with six 533mm torpedo tubes and is equipped with 24 or 40 mines. Due to the installation of the federally newly developed hydraulic auxiliary loading system, the "Orca-class" attack submarine can operate in 20
18 torpedoes were launched within minutes; due to "
The hull of the "Orca-class" is very large. The Naval Research Institute specially added a 37mm rapid-fire cannon to the submarine's front deck, plus a 19mm twin anti-aircraft heavy machine gun on the upper deck of the submarine.
The surface attack power of the Orca-class attack submarine has also been greatly enhanced.
This attack submarine is equipped with a standard crew of 55, with a designed diving depth of 150 meters and a maximum diving depth of more than 300 meters.
