Ask for information on China s latest conventional submarines, plus points

Meta-level. The Yuan-class submarine is a third-generation submarine developed by China, which is much higher than the Song-class in terms of noise control or advanced equipment, or the degree of automation, and is a relatively advanced submarine among international conventional submarines. There is a school of thought that the "Yuan" class should be the younger brother of the Russian "Kilo class", which evolved from the Kilo class, and there is also a school of thought that the Yuan-class submarine should belong to the improved version of the Russian "Amur" class.

For China's Yuan-class submarines, foreign leaders are unanimous and firm and unequivocally pointed out that China already has ALP technology, on the grounds that China's ally Pakistan has obtained the AIP technology of the Agosta-90B submarine from France, and China seems to have independently developed another AIP Stirling engine However, the efficiency is too low and needs to be improved.

A submarine is a type of ship that can dive underwater for activities and operations, also known as a submarine, and is one of the main types of ships in the Navy.

The main role of submarines in combat is: to carry out nuclear attacks on strategic targets on land and destroy the enemy's military, political and economic centers; destroy transport ships and disrupt enemy sea lines of communication; attack large and medium-sized surface ships and submarines; Mine-laying, reconnaissance, rescue and repatriation of special personnel landing, etc.

Able to use the cover of water layers to carry out covert activities and carry out surprise attacks on the enemy; It has a large self-sufficiency, endurance and combat radius, can be far away from the base, and can fight independently in a longer period of time and a larger ocean area or even deep into the enemy's sea area, and has a strong assault power; It can launch missiles, torpedoes and lay mines underwater to attack sea and land targets.

A submarine is a ship that can sail on the surface and dive into the water at a certain depth to conduct mobile operations, also known as a submarine, and is one of the main types of ships of the navy. The main role of submarines in battle is: to carry out nuclear attacks on strategic targets on land and destroy the enemy's military, political, and economic centers; destroy transport ships and disrupt enemy sea lines of communication; attack large and medium-sized surface ships and submarines; Mine-laying, reconnaissance, rescue and repatriation of special personnel landing, etc.

What about the submarine? Next time I write a note.

No. The nuclear reactor of the nuclear submarine is very radiating, and a thick lead wall should be built around it to absorb and block, otherwise the soldiers will be exposed, and the body cells will be prone to cancer. Moreover, nuclear submarines are not directly reactive to power supply, they need a lot of air to operate.

Generally, nuclear submarines travel at high speed under the sea for 3 hours, and run out of electricity after 9 hours of slow speed. It needs to be floated to the surface to charge, and it is necessary to design the air intake pipe to connect to the reactor, and the conventional power only needs to burn fuel, which is not so complicated, and the reactor armor of the nuclear submarine is very thick to prevent rupture and leakage. Therefore, it should not be disturbed to install small reactors directly.

If this is possible, why should every country that has submarines be carefully designed.

Conventional submarines use diesel engines, and the power of nuclear submarines is composed of reactor + steam turbine + diesel engine (diesel engine is used as backup power). The interior space of conventional submarines is expensive, and due to space constraints, it is almost impossible to transform them into nuclear submarines.

Of course, there is also a technology to install a miniaturized reactor (less than 1MW), but as a backup power, it still uses diesel as the main power system. It is a small nuclear-powered AIP system. It still falls under the category of "conventional submarines", or some conventional submarines can be upgraded or retrofitted.

At present, Canada has this technology, but the nuclear issue is still relatively sensitive, and no country is really pretending to be ready for it.

France's Ruby-class nuclear submarine is a large and small tonnage nuclear submarine (about 2600 tons) but its functions are limited, and the cost is not much lower than that of large nuclear submarines, so from the perspective of cost, large nuclear submarines are more cost-effective than small ones.

In addition, the nuclear submarine is not simply to add a reactor, there are many requirements.

A small reactor is also a reactor, it is only small in power, and the structure is also complete, and the working principle is the same as that of a large one. That is to say, the main noise of the nuclear submarine, the steam turbine pin reduction macro vertical gear noise, it is also indispensable, so this design provides excellent endurance at the same time, there is also much greater noise. Due to the large tonnage, large nuclear submarines can provide more space and means to reduce noise, while small submarines do not have this ability, so its noise reduction level is not as good as that of large nuclear submarines, and of course it cannot be compared with conventional submarines that only use motors.

Brother, this is not the same as your house.
