The representative of the Navy: the construction of diesel-electric submarines "Lada" will be terminated

Submarines of the 677 "Lada" project will no longer be built, funding will be directed to the "Kalina" project (improved "Lada"), reports Look with reference to RIA News.

At the moment, the head boat of the St. Petersburg project is undergoing testing, the other two are being built at the Admiralty Shipyards.

"Command fleet decided to finish building two boats of Project 677 "Lada" and stop construction on this. All three boats of this project will be included in the combat structure of the Baltic Fleet. Financing will be directed to the Kalina project, ”an unnamed Navy representative told the agency.

According to him, the new project "Kalina", on which the Central Design Bureau "Rubin" is working, provides for the installation of an anaerobic (air independent) power plant on the submarine.

Help newspaper: "The head submarine of the project 677" St. Petersburg "(code" Lada ") was laid in 1997 year, launched in 2004 year and is in trial operation of the Navy with 2010 year. The ship’s displacement is 1765 tons, the maximum immersion depth of 300 meters, the crew of 35 people, autonomy up to 45 days. "

.. exactly .. low enriched uranium .. ours went, as always, in a different way ..

The first prototype of a new atomic power source - the so-called nuclear battery - will appear in Russia by 2017, said Peter Gavrilov, director of the FSUE MCC (Mining and Chemical Combine, part of Rosatom).
Such “charging” based on the beta radiation source of the nickel-63 isotope can supply electronic devices with power for almost 50 years. The manufacture of the new device is based on the beta-voltaic effect, due to which beta radiation is converted into electricity. The atomic power source has huge potential in the space industry, various underwater systems, medicine and the defense industry, and in the future in the transport industry.
We have already made targets, nickel-62 in Zheleznogorsk has already been worked out, in October we plan to load the targets in the reactor, it will take about a year, ”Tavs Gavrilova said.“ That is, at the end of 2016 we will produce nickel-63. By 2017, the first prototype of such a battery will appear, it is premature to expect earlier. ”
The uniqueness of the atomic battery is also in size. Compared to lithium-ion batteries, the nickel-63 battery is 30 times smaller. In addition, it is environmentally friendly and harmless to humans due to the production of soft beta radiation, which is self-absorbing inside the battery and does not go out.

For ALL submarines go to nuclear weapons, working without air. Therefore, the answer is logical: 100% of US submarines - have air-independent power plants. But the crew still breathes air! Therefore, no fleet has 100% non-volatile submarines yet!

In the USSR, in the 50s, tests of boats with VNEU took place.

After the war in the USSR, one of the deputies of Helmut Walter, a certain Franz Statetskiy, expressed a desire to work. Statetski and the “technical intelligence” group for the export of military technology from Germany under the leadership of Admiral L. A. Korshunov found in Germany the Bruner-Kanis-Raider company, which was a subcontractor in the manufacture of Walther’s turbine units.

To copy a German submarine with Walther’s propulsion system, first in Germany and then in the USSR under the leadership of A. A. Antipin an “Antipin Bureau” was created, an organization from which, thanks to the efforts of the chief designer of the submarines (captain I rank) A. A. Antipin the Rubin LMBP and the Malachite SPMB were formed.

The task of the bureau was to copy the achievements of the Germans in new submarines (diesel, electric, steam and gas turbines), but the main task was to repeat the speeds of German submarines with the Walter cycle.

As a result of the work done, it was possible to completely restore the documentation, manufacture (partly from German, partly from newly manufactured units) and test the steam and gas turbine installation of German boats of the XXVI series.

After that, it was decided to build a Soviet submarine with the engine of Walter. Subject development of submarines with PSTU Walter called the project 617.
In 1951, a project 617 boat, called the S-99, was laid in Leningrad at factory No. 196. On April 21, 1955, the boat was put to state tests completed on March 20, 1956. The test results indicate: ... For the first time, an underwater speed of 20 knots was reached for 6 hours ....

In 1956-1958, Project 643 large boats were designed with a surface displacement of 1865 tons and already with two Voltaire State Technical University. However, in connection with the creation of a preliminary design of the first Soviet submarines with nuclear power plants, the project was closed. But the research at the Perm State Technical University of the S-99 boat did not stop, but was transferred to the mainstream of considering the possibility of using the Walter engine in the giant T-15 torpedo under development with an atomic charge, proposed by Sakharov to destroy US naval bases and ports. The T-15 was supposed to have a length of 24 m, an underwater range of up to 40-50 miles, and carry a thermonuclear warhead capable of causing an artificial tsunami to destroy coastal cities of the United States.

[Technical engineer]

The first such boats were the Germans during the war years, the second the USSR in the fifties. So, you should not think that anaerobic plants, something new. Just something anaerobic submarines will be inferior to conventional diesel-electric submarines. Although the other is superior. The question is simply which parameter is in priority. Underwater speed or noiselessness.

In Sweden, in 1988, the Nakken-type head submarine was converted to Stirling engines. With them she went under water for more than 10 000 hours. The Swedes ushered in an era of submarine shipbuilding ancillary anaerobic propulsion systems.
Russia at that time (USSR), under the control of the traitor Gorbachev, began to slide into the abyss. The submarine fleet was not up to anaerobic propulsion systems.

.. different approach to solving the problem .. The characteristics of the new Russian engine were not disclosed, but it is known for sure: it belongs to the type of air-independent power plants. Such engines have the most advanced German diesel-electric submarines of the U-212 and U-214 projects to date. The Russian anaerobic power plant is based on the conversion of chemical energy into electrical energy without movement and combustion. In fact, it is an electrochemical generator where a chemical reaction occurs - a combination of oxygen and hydrogen, while the electricity is released silently, and the only by-product of the process is distilled water. The efficiency of such an installation reaches 70 percent, and the noise level of the submarine on the anaerobic course is lower than natural sea noise ..

The Americans do not build closed-loop boats on the basis of anaerobic tubes although a similar engine was created back in 1986, but why not answer? The USSR and now Russia has been carrying out technological development for almost 50 years and .......... .
The Germans came to the conclusion that there is a dead end in this technology and are slowly starting to abandon it.
Refusal to build boats of Project 677 "Lada" I consider a mistake, according to available information, our engine still has "childhood diseases" and needs improvement, not to mention that it is inferior to the German one.

The reports of the American Physical Society and the National Academy of Sciences of the USA note: in order to implement the program of widespread use of hydrogen energy it is necessary to make a technological breakthrough in at least 100 areas of modern science

Quote: Maxom75

Apparently, what was expected didn’t go, did you decide to immediately jump over the generation?

A series of 3 (5th generation, Lada) essentially became a test ball for the introduction of non-nuclear energy in submarines (NPL).
"St. Petersburg" by the end of construction did not receive the installation promised by the industry. The stand and the compartment on the submarine are two big differences, as they said in Odessa. The stand VNEU on the ship did not pull ... 60 (70)% of the nominal is the failure to fulfill the TTZ. Nobody will take responsibility by deciding to build a large series of "underfuel"? Vysotsky, just as he merged Bark, also leaked Lada, saying that the fleet did not need such boats.
Then the naval "drew attention" to the "wonderful" capabilities of LIAB !!! And already the designers from Rubin screamed about the tremendous capacity of such AB, giving 2500 h / A from one element, for underwater movement. As a way out of the situation, we decided to put them on the 2nd building of Lada (Kronstadt) and see what happens (the 3rd is still reserved for VNEU). But the intrigue developed further.
Brothers "Tatars" from the Kazan Institute of Organic and Physical Chemistry. AE Arbuzova, "experimenting" with palladium and platinum membranes, suddenly discovered that precious "products" can be replaced (without compromising the quality of hydrogen) with organic ones !!! And at once everything becomes profitable: the price falls, the attractiveness of the "non-gold" installation increases sharply.
Next, more. "Sarov" skated our VNEU at sea. It reached its design capacity (300, according to other sources - 400 kW), while the best "for a ruble ebony" installations = only 180 kW. Light dawned at the end of the tunnel!
Science and promises have sworn on the Bible that they will do by 2018, and by 2019 they will put a transport version of the installation on the ship. Therefore, Chirkov, leaving the reserve, decided to build Kalina. The Queen in the Northern Fleet needs nuclear-powered submarines and 6th generation nuclear submarines to close the BMZ fleet and to ensure the deployment of the main missile-based submarine. Therefore, Lada with the whole herd and go to the BF! What is very good for the fleet, because who will comb Gotland.
That's where the foreign interest in our VNEU came from.
And Kalina - it is cured from childhood diseases Lada. But an ambush is also expected here if our experimenters fulfill the threat of equipping the ship with modular structures and uninhabited underwater vehicles. Then we will definitely wait until 2025 for the wunderwaffle of the domestic fleet, which has no analogues in the world.

On hydrogen fuel cells, most likely. In them, the reaction of the combination of hydrogen and oxygen with the formation of water and the release of heat.

Electricity is produced by combining hydrogen and oxygen, which are supplied from the air to the proton exchange membrane in a stack of fuel cells.

(Whatever it means )

[donavi49]

Not two options.

Reactor with hydrogen.
Stirling - but stirling will require a revolution in engine building at least in a separate complex (traditional knocks, troits, the main thing works, take the engine will not take off) and support the cosmic culture of production. Stirling has fantastic requirements for precision manufacturing, and these are machines that are quite difficult to get now, and for that class of machine tools it’s the turn of 5 + years. These are unique requirements for build quality, individual debugging of each engine, numerous tests, on-site commissioning, proper monitoring and maintenance.

However, in general - Stirling is cheaper in operation and safer, the reactor is more demanding, difficult to operate.

The Germans have a reactor.
China, Norway, Japan have Stirling.

By the way, the Americans back in the 1960s created their anaerobic engine, but did not use it, since at about the same time they completely abandoned diesel submarines and only made nuclear ones. Nevertheless, today the technology of non-volatile engines is used in several countries of the world that patrol in inland seas. In limited water areas, boats of this type can cope with the same tasks as nuclear submarines, but at a lower cost. It is necessary to develop such technology in Russia: without a modern power plant, submarines become uncompetitive at sea and in the arms market; recently, foreign buyers demand, put forward conditions - to put an anaerobic engine on non-nuclear submarines. ”

The main trend in the development of submarines will always be a further increase in stealth. Small submarines equipped with air-independent power plants, according to experts, are considered the standard of invisibility, and not without reason. For example, during two exercises in the Atlantic in 2003, the Swedish Halland boat with anaerobic engines, which was used as a training target, outplayed the Spanish submarine with a conventional diesel-electric installation in a duel situation, and then the French nuclear submarine. Later, Halland in the Mediterranean managed to get away from the American nuclear submarine Houston (type Los Angeles). It should be noted that the low-noise and high-performance Halland costs 4,5 times cheaper than its nuclear rivals.

German-made Israeli anaerobic "Dolphins" have an autonomy of 30 days and a cruising range of up to 8000 miles.

They do not have strategic significance, due to low autonomy (no more than 30 days).

Not autonomy, but carried weapon determines the "strategic" of the carrier.

Yes, I understand the identity with which intercontinental nuclear weapons = strategic.
It always seemed to me that strategic is not equal to atomic at 100%.
There are also strategic tasks.


As an example of a strategic purpose.
If the 30 submarines can block all the naval communications of the adversary in the form of a whole continent, having traveled 7-8 thousand miles and staying for such a long period, then this is a strategic task.
The submarine is within reach.
DEPL with VNEU - no.

I don’t know how in Lada, but in Varshavyanka there used to be quiet horror. In any case, I thought so. Shponok for l / s only in two shifts, each does not have one. Fortunately, they didn’t run far and not for long.

Well, the Yankees on Elk (if memory serves) have one berth for two, and after all an atomic, not a DEP ... Well, you have to face the fact that non-nuclear submarines will be inferior in comfort to atomic for a long time and will not them saunas and pools like the Typhoons

30 days of autonomy .. roughly .. and there is no window to float up - snorkel - start a diesel engine - charge the accumulators .. depths of immersion up to 400 m .. for a day at 20 knots will go far .. what kind of garden to fence ???

[cosmos-PS]

The Lada project was originally supposed to be with an anaerobic plant. But with the installation, they were busy for a long time and only now something happened. But it seems that the alteration is getting serious and it's easier to start a new project. And it’s not surprising if something has become outdated during this time and needs improvement. It is good that they decided to finish building the last two boats, otherwise they would remodel them under the new project for another five years, not counting the testing and acceptance.

Thanks, read! I have already read the memoirs and memoirs of some submariners Krismarine (albeit mostly in snatches) and have already made sure that fighting on "this" was "unpleasant" (sleeping in an embrace with torpedoes, dog cold, latrine does not work ...)
Compared to U-bots Pike and S-cams, the same Varshavyanka is like a 4-star hotel after the hostel

The book is good. The author is one of the few submariners who went through almost the entire war. And besides, the commander of the submarine that survived

[NEXUS]

The question then arises is: When will the first submarine of the Kalina project be laid?

[chunga-changa]

In the west, a stirling engine is used. Since the 80s, now the main players are building the third generation of boats with VNEU. Hydrogen and oxygen are stored in the tanks on board the submarines; they ensure the operation of the engine by combustion. The engine turns the generator, the generator gives current, the current is used to move and charge the batteries. Oxygen and hydrogen are charged into tanks from the shore, where there is an installation for their production.
Ours are developing a fuel cell engine "By catalytic reforming of diesel fuel". Those. hydrogen is obtained from kerosene on board the submarine, oxygen is stored in tanks, then everything is like with foreigners.
In general, the difference is only in the method of producing hydrogen, foreigners are preparing it on the shore, ours are on board the submarine. Because of this difference, all the boron cheese. At one time, it was thought that it’s easier, you do not need to build hydrogen production plants near military bases. It turned out that the problem of reforming was not so easy to solve, as a result, we still do not have a modern non-nuclear submarine with VNEU and the prospects are still somewhat vague.
In general, as a result of the ineradicable desire to come up with our own bike that has no world analogues, we lag behind generations of non-nuclear submarines. The Swedes are now designing and building the fourth generation of submarines with VNEU, the Germans - the third, the French - the third, the Japanese - like the second, South Korea - the first on the basis of the German second, India - the first, on the basis of the French second. Even the Dutch are building with the Spaniards and Brazilians.
Submarines without VNEU are now interested in countries of the level of Vietnam-Algeria. India has announced a competition - 6 submarines for 8 billion. We are participating in it purely theoretically, because we can only offer a theoretical Amur-1650, for which there is no VNEU yet. The only hope is that they will carry out it as usual - for five or six years, by that time we may have our own creation, or we will have to install an Indian stirling engine.

There is no kerosene on the boats, only diesel fuel. Our ECG provides electricity, water and heat. Electricity - to move, or to AB. The question is about a single engine, so as not to carry a diesel engine. But this is possible with a 100% guarantee of reliability that no one will give. Nuclear carriers and those have DG ...

Quote: chunga-changa

We lag behind non-nuclear submarines for generations.

We do not have NPL yet.
But in 2019 (God forbid that everything was according to plan!) We will become the most advanced country in the NPL race. This was already understood by deutschers and quietly picking our and Amer’s theme with reforming and direct electrochemical reaction with the release of electricity without mechanically displaced elements of electric power. This technology gives an efficiency of up to 75%.

The top two TAs can fire remote-controlled torpedoes. The open press speaks only about TEST-71, but I see no obstacles to the modernization of the BIUS and the TU system in order to use the UGST, especially since it is exhibited for a foreign customer.

, so talking about our "leap" is not particularly appropriate.

So you are aware of our principle of VNU? Or, still not? Well, and if it is, for example, a mini-reactor for charging the battery? Of course, I am also a frenzied pessimist, but not to the same extent (no offense)

This is true, note:
Recently, an American consortium of federal laboratories for technology transfer (FLC) presented the Notable Technology Development Award from Hyperion Power Generation from Santa Fe. An outstanding achievement is Hyperion Power Module, an almost domestic nuclear power reactor.

Hyperion is an extremely compact plant powered by low enriched uranium. It is capable of delivering electrical power of 25-27 megawatts

So you know that it will be a mini-reactor for charging the battery? Of course, I, too, am a rabid OPTIMIST, but not to the same extent (no offense)

somehow not logical, however. When I come, for example, to a car dealership and I wish I fret viburnum. And the manager, at the same time, Kondraty will seize: because, as he will be in prostration, what the client wants is either fret, or viburnum. Which eyeliner? But not a word about vodka !!!!!!!!!!!!!!

“The command of the fleet made a decision to finish building two boats of Project 677 Lada and stop construction there. All three boats of this project will be included in the combat composition of the Baltic Fleet. Funding will be directed to the Kalina project, ”an unnamed representative of the Navy told the agency.] If you translate this message into ordinary language (philistine), it looks like this: Due to the crisis, all ministries (including the RF Ministry of Defense ) a command was given to reduce the implementation of some programs, projects, so the construction of diesel-electric submarines of the Lada project is terminated, while the financing of the Kalina project, or rather R&D and R&D under this project, requires much less funds. Moreover, there were no official reports about the immediate prospects for the laying and construction of boats of this project.

For a minus I will report. For example, "Priora", I saw before my eyes, the mileage was 160 thousand km. During the operation, the car stood up once, knocked out the fuse for the power supply of the ignition coils and other electrics on the engine. The reason was a malfunction of the speed sensor (short closure), well, "zatroil" once came out of the standing ignition coil. The most interesting thing is that the service car was used in the structure of the FSB, i.e. drove her into the tail and into the mane without sparing. Not a special vehicle, but just a traveling bibik, which is now being distributed to the Ministry of Internal Affairs and other departments.
Therefore, not everything is so bad with our car industry ...

A couple of days ago, with drumming and shouting cheers, they wrote and commented on which Lada is a great boat, now you give Kalina. To ask from designers for national money.

[Andrew]

It is a pity, of course, that the production of this submarine will end with only 3 units! The maximum delivery time is 2019, because as it was written, everything will go to the production of diesel-electric submarines of the new generation (5) of the Kalina project, it will be laid in 2018, and included in the GPV 2018-2025 (I don't remember exactly since 2018). And so it would be good to modernize all diesel-electric submarines of Project 636 "Varshavyanka" for "Lada", because at Lada, systematization is better for this there is a crew (21-35 people). And her invisibility, in childish language, is slightly better than that of Varshavyanka. And it carries not 4 anti-ship missiles / cruise missiles Onyx / Caliber, but already 10 pieces already! Despite the fact that it has a displacement less than that of Varshavyanka (1765 vs 2350), well, there probably is closer than in Varshavyanka! It would be even better if the most combat-ready, ie young and not in need of repair diesel-electric submarines of Project "Halibut" were upgraded to the level of "Lada". Well, I was already dreaming about it!)) This is Kalina, unlike Lada Kalina, has no analogues in the world (at the moment)
