China has tested a new submarine project Type 039A

China conducted tests of the Type 039A submarine with an air-independent propulsion system, Warspot reports with reference to the portal navyrecognition.com, while the details of the tests are not called.

The Chinese Navy, after conducting a test cycle, said that the Type 039A submarine "broke all Chinese records fleet the duration of being under water and the depth of immersion, yielding only to nuclear submarines. "According to the Navy, the new submarine can not float for two to three weeks, while submarines with traditional diesel engines can spend under water from 10 to 100 hours.

Recall that last year, China at the IDEX 2017 exhibition presented a model of a domestic submarine of the S-26 type with an air-independent propulsion system. The model was equipped with a Stirling engine, as well as a large tank for liquid oxygen. Submarines of the S-26 type are a modification of the diesel-electric submarines Type 039 (Yuan), which are in service with the Chinese Navy since the 1999 of the year. Earlier, the Navy announced plans to equip all diesel-electric Type 039 (Yuan) submarines with an air-independent propulsion system.

According to the developers, the S-26 submarine with an anaerobic installation has a length of 79,5 meters and a displacement of 2660 tons. The submarine is capable of sinking to a depth of 300 meters. Power reserve is 8000 miles at a speed in the 4 node, and the maximum speed of the submarine under water reaches 18 nodes.

Only China before - in fact, the head boat of the Chinese project already served when the Lada was a mortgage compartment. And by the time testing began, China already had 7 Type039 boats.

Let's all boats with rudders on the wheelhouse - call Lada clones. Only then will you have to call Lada a clone of the American - who first applied such technology on Skipjack boats in the distant 57.

Why would you? Why are we going to copy something? We are on a different path — hydrogen production on board, an electrochemical reaction in a fuel cell with bound oxygen, rather than carrying oxygen on board like a time bomb, not knowing what time the “X” hour is set at.
And the Chinas pulled off their project from the Swedes - and did not even frown! Just like the contours and line-up of our Lada.
Somehow, however.

Good evening,

Hi friend!
Kitaisa, very painstakingly hardworking "closers" of other people's ideas and products. It is a fact! But I missed something on the issue of NEW-Stirlig, "maid in Hina" ... Therefore, the idea has not changed, and the details cannot take the old cart to a new level: anyway, it will not become a car. I'm sorry.

Quote from rudolf

If I am not mistaken, the oxygen for ECG will be unbound. In a cryogenic state in cylinders in the interbody.

To be honest, this is news to me. Because I sincerely believed that its metal hydrites in a bound, solid form in the fuel elements would contain. If what you wrote is true - tady OH! Our technical culture is not like that of deutschers, you yourself understand what I mean ... No matter what happens ...

Quote from rudolf

when we finally give birth to our installation, it turns out that we caught up not even yesterday, but the day before yesterday.

Yes, it seems that along this path we are "young pioneers." Even amas stomp after us. Can we organize a breakthrough in new gray-ab ??? Then we jump out of a number of mediocrity.
IMHO.

[Magic archer]

I wonder where and from whom the Chinese stole VNEU ?! Atomic submarines are still the Achilles heel of the Chinese fleet. But with VNEU already

[cariperpaint]

Tests are not. Ours have been testing for years, so far there is little sense

[faiver]

well, ours have been building for a long time and through one place lately, but I don’t really believe the Chinese

[-Pollux]

The Sterlig engine is not VNEU they need air, just unlike diesel engines they can work under water. It is clear that such a submarine will buzz an order of magnitude louder than a diesel-electric

The party ordered and the Chinese engineers invented themselves, and the workers bungled)))
P.S. And so ... I think that there is nothing shameful in borrowing, if it is for the good of the Motherland. And if it is to strengthen defense power, then this is a doubly worthy feat. And robbed, let them stomp angrily with a leg --- for China their indignation is of little interest.

It’s not their fault that these cars are generally similar .... Dear Stirling, separately, and a group of Chinese engineers under the leadership of Xing Ding Ling is also separate. Coincidence. And the fact that the East takes so long ---- is in no hurry.

Damn they give, then three destroyers, then tests of submarines with VNEU .. They rivet equipment and ships like Chinese toys, but the toys break immediately .. let's hope and here it is ..

Interestingly, and what is the range at 18 knots? 8000 miles at 4 knots is almost 3 months!

[donavi49]

Question. Well, it’s more like in football. If you count the kilometers even for what Messi you traveled in the match and calculate the average speed. You will easily overtake him. But if you put you next.

It’s similar here. When there is no special need (being in the square) - they charge the batteries, go to the 4 nodes. When the need arises, they use high speed. Then again charging. Only unlike Varshavyanka - a Chinese can spend the entire military campaign at any depth, remaining as inconspicuous as possible. Varshavyanki - have to swim up to charge.

Stirling - even if you take Chinese technology and assume significantly greater noise, especially considering that you can use the most comfortable depth or terrain, it is much more difficult to detect than snorkel + operation of the main diesels at Varshavyanka.

Submarines of type S-26 are a modification of Type 039 (Yuan) diesel-electric submarines, which have been in service with the Chinese Navy since 1999.

[NF68]

Here is backward China.

[Topotun]

There were reports in the media (a couple of years ago) that like we already have VNEU developments (like on the catalytic decomposition of fossil fuels, if I understood correctly). And it seems like they are ready to put them on a submarine like Varshavyanka. And where is it? But the Chinese are great. Although the heat of their weapons is somewhat annoying. Against whom, here's the question ....

[donavi49]

At the stand in a preprototype state.

In general, briefly:
- any reactor, expensive (that’s what you indicated - this is the German way, the differences are only in the component groups).
- Any Stirling requires a very high culture and accuracy of production. Plus has its drawbacks - for example, it is an engine, that is, a source of noise and vibration.

Now there is a new option - use a new generation of extra-large batteries. The pioneers here are Japanese (well, not surprisingly, they are No. 1 in batteries now). And they have their own Stirling on serial boats such as Soryu. But the last two boats of this project are without Stirling, with larger battery compartments and a new generation of batteries. They declare that these boats can carry a database equivalent to Soryu boats equipped with Stirling. Head through 1,5 of the year will go to the test. Cost increase from Stringing 100mln dollars (from 450 to 566mln with new batteries).

[Ace Tambourine]

But it’s interesting .. What are the Chinese people calling the servicemen in the engine compartment? Or is it the Chinese? +
And the torpedoes? ...

Last spring, the Rubin Central Design Bureau of Marine Engineering completed the design of the fifth-generation Kalina, a fifth-generation diesel-electric submarine capable of being under water for significantly longer than modern ships of this class. The new ship will receive a non-volatile power plant operating on highly purified hydrogen-containing gas. It will be received on board a diesel-powered submarine by reforming.
The resulting hydrogen will be supplied to hydrogen-oxygen fuel cells, where electricity will be generated for engines and on-board systems. With this scheme, designers expect to get a method of almost silent power generation. As expected, the capacity of the installation developed by Rubin will be about 400 kilowatts. The development of an anaerobic power plant is scheduled to be completed in 2018.

And about the Russian surface fleet, because a similar situation. Just two weeks ago, I wrote in the article “Marine Superpower” that the laying of the newest Russian destroyer of project 23560 “Leader”, the design of which was carried out since 2009, was postponed indefinitely - after 2020. This fact confirmed my version that Russian shipyards are not able today to cope with the construction of a surface combat ship with a displacement of more than 10 thousand tons. And now, less than half a year has passed, and another hint appears that poor fellow Leader may not see the horizon at all. So, according to the draft Strategy for the Development of the Shipbuilding Industry until 2035, which was prepared by the Ministry of Industry and Trade of the Russian Federation, such objects are imaginary the pride of Russians as an aircraft carrier of the 23000E Storm project and the above-mentioned destroyer of the 23560 Leader project, if oil prices fall to $ 60 per barrel or lower, they may not see the light of day until 2035. And who will need them in 2035, outdated and “dull” - the question is already another.
