How the "underwater terminator" was created

91
The Soviet nuclear submarine of the 705 "Lyra" project became the top of the food chain in the underwater world. Like a shark. Thanks to the revolutionary technical solutions, the submarine could catch up and hit any target, but no one could hit it. The creation of the Alfa (the name of NATO submarines according to the NATO classification) changed the world tactics of underwater combat, the US high-speed torpedoes and missile-torpedoes came into being thanks to the submarine.
The only weapons of the 705th project were torpedoes, six devices in the nose. The submarine was created to hunt for enemy submarines and duel situations. IN aviation such devices are called fighters. The designers were given the task: to create a submarine that can evade weapons. To this end, a special decree of the Central Committee and the Council of Ministers of the USSR SKB-143 (now SPBMB Malachite) was allowed to depart from the norms and rules of military shipbuilding if they prove the need for such measures. The designers completed the task.


The boat turned out to be a small one, with a displacement of just over 3000 tons, with one propeller and a compact streamlined cabin. The swift outlines of the Lyra resemble a large marine predator - for example, an orca. The titanium hull reduced the visibility and weight of the submarine, sharply increasing speed and maneuverability. The design of the submarine applied revolutionary at the time solutions.

The reactor was with a metal coolant. This created a lot of problems with maintaining its working temperature, but the boat developed a full course from its place in a minute. The power plant turned out to be light - the weight of the reactor on the 300 tons less than that of other submarines - and compact. In this case, the complexity of the construction of "Lyra" was included in the legend. Virtuoso welders "Sevmash" bent the electrodes and used mirrors to lead the seam in a jumble of cables and pipelines.

Submarine control was maximally automated (even the galley was mechanized), thanks to which the crew was tripled compared to conventional submarines. There were no watch in the compartments - control of all systems of parameters was carried out from the central post. A combat shift consisted of eight people. On the "Lire" first appeared rescue capsule - in an accident the crew went into the pop-up cabin. For 20 years of operation of this type of submarine they did not die a single person.

- We had highly professional crews: an 24 officer, six midshipmen and a sailor. And when not a first-year-old sailor sits at the console of acoustics, but a captain of the third rank, a fire, water and copper pipes, he discovers such targets that no electronics can see, ”said Alexey Potekhin, who had commanded one of the Lear for eight years.

Good advertising submarine made American fiction writer Tom Clancy. In his novels, Alfa was described as the evil genius of American submariners, invulnerable and deadly. Able to escape from the enemy torpedoes and catch up with any ship "Lira" has earned such a reputation. Under the water, "Lira" accelerated from the spot to the 41 node in a minute and at full speed could in 42 seconds turn into 180 degrees.

The favorite entertainment of Soviet long-range pilots was to scare American aircraft carriers. Having tracked the warrant somewhere in the Atlantic, the Tu-95 was sneaking up on a shaving plane and roaring over the flight deck. Aviators photographed enemy technology and showed friendly gestures through the windows. The underwater analogue of the fun (and the combat mission at the same time) was the pursuit of American submarines. Off the coast of the United States, the Lyra stuck to the missile carrier that had gone on combat duty and pursued it for weeks without giving it access to the destination area.

Especially for the "Lyra" created a pneumatic torpedo tubes, which allowed to shoot from any depth, and later became the famous rocket-torpedoes "Squall". The option of equipping the submarine with ballistic missiles was considered, but it required serious changes in the design of the submarine and abandoned the strategic version. "Lira" remained underwater fighter, titanium shark.

      The society needs to restore the request for a similar state of affairs. For 25 years of the open collapse of education and the destruction of morality, a generation has grown up far in its mass from the understanding that all Russian peoples can only survive together. Liberalism, which has taken the form of banal egoism, must be eradicated. When the majority understands this, then we will have a sufficient number of design school, production, boats and submariners themselves, and everything else will appear ...

        So far, the youngsters have the opinion (inspired by annoying advertising) that EVERYTHING can be achieved without any extra effort. Never sweating and never getting sick of ... They don't read, they don't study, they just crawl on the table with the "mouse". And in the computer games they love so much, they don't want to do anything that strains the brain. They want to bend right away. The trend is dangerous. the Americans have achieved their goal. Most of the younger generation is completely mortified.

      And they were ruined by the lack of coastal infrastructure .. Well, they could not build a boiler house on the coast to supply heat to the boat and they could not organize electricity either. So they ruined the first boat in the series .. Alas, but this error is systemic, for some reason under the USSR they did not spare money for billions of dollars in equipment and pitiful millions for infrastructures for both equipment and people were a pity .. The most expensive ship in the history of the Soviet Navy " Ural "was destroyed for the same reason, like many other things ..

        > And ruined their lack of coastal infrastructure.

        even now fast neutron reactors are the most problematic and unstudied among nuclear reactors, here the BN-800 was commissioned with great difficulty. Slow neutron reactors passed this power level somewhere in the 70s - this difference is due to the huge and not completely solved scientific and technical problems of operating reactors with BN.
        Today, in the world, in addition to the Russian Federation, not a single country is developing the direction of nuclear energy with fast neutrons - they cannot, it does not work out. The Japanese, even having received a full package of documentation on BN-600, could not launch it.
        Of course, BN reactors have enormous advantages and prospects, after the basic issues of their operation are resolved.

        Soviet submarines with BN were accumulating experience in operating and designing such reactors, and when land reactors with BN enter the problem-free category, the fleet will definitely have to return, but at a different technical level.

            1) Isn't the speed of thermal neutrons small compared to that typical of BN?

            2) And why confuse the forum readers with the special terminology of the nuclear industry, for them, for the most part, incomprehensible?

            And about "not in nature" you said it strongly. For any beam / stream of particles with a rest mass above zero, there is always a velocity spread, which means that for this stream / particle stream the expression slow particle always meaningful

        The cars were beautiful. I saw them in Zapadnaya Litsa in 1988-89, such babies, compared to the "loaves" and our BDRM, stood next to them on the "Kumzha". It was interesting to see how the people were walking back and forth through a small "hole" in the forward part of the wheelhouse, it was unusual for us. And with the infrastructure then really was not very good. The food from the shore was constantly jumping, and for the 705, steam was also needed.

          Of course, it is easier to close the plant and deprive specialists of work than to build wastewater treatment plants. Is it true? And the transfer of the plant is so expensive, it’s easier to close it. What about people? What about people? Let them go to managers and traders!

          factories: ChMZ,

          While alive, but on its last legs, the production of "200" (uranium products, that is), almost everything was transferred to subcontractors in Omsk, Novosibirsk, Krasnoyarsk-26 .. It was it that brought the main money. Despite the statements of Rosatom (about contracts for 100 nuclear reactors), judging by the volume of orders for zirconium and related materials, ALL of them (Rosatom) are going to buy it somewhere else .. This technology (zirconium) is used only by us, China, and France, ChMP does not have any contracts for this type of product (100 reactors are VERY many) and no one in Russia produces zirconium anymore (all the others work with semi-finished products from ChMP), the French are expensive, and the sanctions are expensive, China remains with its stolen technologies (I remember as in the 90s, Chinese delegations walked in droves around a regime enterprise) these should be cheap (rollback), but here's the quality .. So there are two options, either Rosatom sounds about 100 reactors (otherwise, the workshops would be reconstructed and work in 3 shifts 7 days a week ) or everyone should put Chinese "friends" ..
          rs: And still very disturbing news, the state reserve is being removed from the plant, which they could not completely sell off even in the 90s when absolutely everything was dragged from the enterprise. They are transferred to other cities to factories as related companies, and this is a direct hint that the factory of the khan .. And with it the city of Glazov ..

      The submarine of project 705 (705K) is a two-hull, single-shaft. The body, made of titanium alloy, was a body of revolution along its entire length. The fencing is of a “limousine” type (its contours smoothly interfacing with the contours of the ship's hull were worked out by TsAGI hydrodynamics). The robust housing was divided by transverse bulkheads into six watertight compartments. The 3rd compartment, where the main command post and office space is located, was limited to spherical bulkheads designed for full outboard pressure.

      Comparison of these types among themselves, even by such subtlety as secrecy, looks extremely ambiguous ....

      It’s rather a matter of opinion which one to apply. But taking into account all the factors on the 5-generation, the most optimal one will probably be the one that is now on the 885 / 885-single-hull in parts.

      And on Lear’s account ... Ships came out very ambiguous ... The appearance of new American Mk-48 torpedoes, and after the Tigerfish at the Britons, with their speed and driving characteristics, very quickly depreciated Lyra's speed qualities.

      Plus, their secrecy was not at the highest level, because the thermal field there was very powerful, plus the primary acoustic one at speeds higher than 20 nodes, too, and it was on 40 .... But at a low-noise operation mode there were less, so the stories the fact that they thundered in all modes is still a fairy tale.

      Plus, due to its acoustic field in the corresponding modes, the corresponding interference was created with the operation of its own HAC, which is also not good ...

      Another drawback of the project is to add a meager mod-potential. For upgrades, as a rule, they require free internal volumes, and this is the 1 criterion that determines the mod, but here it was .... Plus, the nuance boats turned out very small, and for them very specific models of equipment were created that were used only on this project, and, say, they wouldn’t fit in any other way ... The same goes for nodes from other projects. That is, you couldn’t even think about unification -for this project was required make only nodes and assemblies only for him, due to its uniqueness.

      Something like that.

        You are partly right! Much of what was used and passed trial operation was subsequently used on other projects of combat nuclear submarines and special purpose nuclear submarines. This also applies to titanium and advanced automation and remote control systems. Small weight and size characteristics of the equipment are just a plus, not a minus. By the way, the Bulava-705 radio intelligence complex is one-to-one, but under the code R-736, 671 RTM projects were used on the nuclear submarine. The use of a 400 Hz electric network, in addition to advantages, also revealed disadvantages, so this current frequency was no longer used on boats as a power one ... This is also a plus. Remote control of the torpedo-missile system began to be used "everywhere". Etc.

      Yes, and we will not forget about the noise, which at full speed, albeit a record one, was such that it was not possible to observe the tracking object. Of course, the training of an unprecedented highly qualified crew allowed us to work miracles, but still the boat resembled a deadly predator that was blind to pursuit. Conclusions have already been made, the game was not worth the candle. Without having served and 20 years all are withdrawn from the fleet. Of course, there is reason for pride, as well as some developments. Let's just say that they are ahead of their time.

    At the modern level, with a new approach to nuclear power plants, automation, with new computers and hydrodynamics, such underwater "predators" could even now "give a rustle" to the striped-eared fleet. Reactors with a liquid metal coolant, with new materials and "Caliber" in torpedo tubes - and the fighter turns into a "ministertega"! True, this boat made a lot of noise at full speed. And all the same, hitting one, maneuvering at a depth at full speed - and not at once figured out what. A nuclear warhead, is that?

        It all depends on the torpedo detection distance. And then it may not catch up, constantly eating the distance until the HB triggers.
        In the history of the fleet there is reliable evidence of an attack by 705 British. Lyra left the torpedo. yes

          Right. Depends on distance and whatnot. "Catch up" at 705 should be fired further than from 25-30 kbt.

          Could you provide a link to the aforementioned "reliable epoch"? For, it seems to me that this is a "fairy tale" retelling of an episode from Tom Clancy's novel "The Red Storm Rises ...", when "Lyra" in a 3 versus 1 situation drowns two of his opponents, moving away from torpedoes (though later it gets here old man Tom was cunning: in that situation I would have left him)

    A masterpiece ruined by inattention to the need to create a coastal structure for basing.

    On the other hand, in the submarine fleet the same situation developed later as in aviation: the means of destruction could catch up with any object at a speed in the submerged position of up to 50-60 knots and at a depth of up to 600-700 meters. And stealth became the most important parameter. And "Lyra" with "Pope" gave way to "Shchukam-B" and then to "Ash"

      At the Nerpa shipyard, the entire infrastructure was practically ready to receive nuclear submarines with OK-550 installations: a boiler room, a separate berth + supply to it of all energy media, including steam and high-frequency chambers, but somehow it did not work out - restructuring began ((((.

    The project, of course, is avant-garde, but what is its real value? The main advantage compared to the rest is speed and acceleration. But at this speed it’s not necessary to talk about stealth or about the possibilities to find an adversary.
    The key factor in the effectiveness of the submarine is still different - to detect the enemy before they can detect it and use weapons with a high probability of hitting the target. And another factor that is extremely important is the effectiveness of the maintenance / service to maintain the readiness to use weapons for a reasonable / sufficient time.

            Everything should be rational / rational, especially where billions are spent, and also on defense. I can repeat once again - the armament must be effective, for a submarine, including the main quality - it was the first to be discovered, the first to be fired, the first to be destroyed. There is nothing new in this; long ago, all modern nuclear submarines are built on the principle of how anyone succeeds. If you do not take into account your desire to remove the 2 circuit, add a diesel electric ship, electromagnets and a lot of metal - why is the boat a huge excess power? Gigantic sizes, capacities are not equivalent to efficiency - we can recall the Shark, P39.

      BN reactors are more compact
      , and if they gained speed in 1 minute, then the maneuvering characteristics of the reactor in power are completely different than in VVER, for which the maximum allowable changes in power are very limited, and the most desirable mode of operation is stable.

      Compactness and the ability to maneuver with power are not at all superfluous. After terrestrial reactors with BN have been worked out, and this has been taken for about 10 years, they will find their place in the fleet

    Project 705 is undoubtedly an outstanding piece of engineering. But the idea of ​​an underwater fighter has probably lost its meaning today, in the form it was laid down in "Lear". However, the idea of ​​creating a relatively small multipurpose nuclear submarine, as automated as possible, is more than relevant. With the priority of stealth and immersion depth. Displacement from 2 to 4 thousand tons. Better to have a flock of three of these PLs than one monster, such as "Ash" or "Anthea". In any case, the combat effectiveness of such a stick will be higher.

    A ship ahead of its time. Favorite ship. The direction of thought is brilliant, the Americans were really shocked and had to urgently create new types of anti-submarine weapons. The adversary himself spoke of the value of this project - all the corps during Gorbachev's perestroika were very quickly cut into pieces with American money. And cutting titanium alloy is not that easy. The best years of service were spent on the ships of this project. In accidents, no one really died, one officer was washed overboard on the surface with strong sea waves, they were not found. There were a lot of technical and organizational innovations: a liquid-metal coolant (LMC) of the 1st circuit, a compact and very powerful reactor on the BN, 5 uninhabited compartments (we all slept and kept watch in compartment 3, only the warrant officer of the 1st battalion BC-5 periodically bypassed the compartments at sea), the officer's crew (sailor, poor fellow, provided 16 table sets per day with washing dishes - three combat shifts + change of flagship specialists-senior inspectors on board x to 4 meals a day), for the first time a system of remote control and management of all valves , devices and mechanisms of the ship from 3 compartments, etc., etc., etc. Our reactor was always in a commissioned state (so as not to freeze the same liquid metal core), so the time of the urgent exit of the ship was practically determined by the time of arrival on board of the entire regular and assigned crew. The list of weapons included not only torpedoes - we fired missiles from torpedo tubes back in the 80s. In general, you cannot list everything. There is a book about the 705th - "The ship ahead of time" is called. I would now go out to sea again with pleasure on board such a ship.

    I saw these Project 705 nuclear submarines at the base and even communicated informally with submarine officers from these vehicles. Informally, at the feasts, many of them seemed to "find fault" round-the-clock worries about their "fish", but often with pride for it. And all this "automatic boat" was initially planned with a crew of almost half the size, but the military was insured. And 705 project - it was a breakthrough of the Soviet submarine and ship industry. It is a pity that its development did not follow.

    It is not so easy even with modern systems to drown such a "shark", small size, tremendous speed and maneuverability - there is every chance to escape unharmed. And if you recreate the project at a new technical level, some people in the Pentagon will sleep very badly. But the BN reactors are still "raw", their time has not come yet. And yet - what a colossal scientific and technical potential the USSR had! Many developments were decades ahead of their time.

    There is no other important addition in the article, the reactor was cooled in the first circuit by metal, a bismuth-lithium mixture, it seems, therefore it was impossible to shut down the reactor on boats. Among the shortcomings: high noise (the noisiest boats), during operation there were problems with controllability (at maximum speeds, control was carried out like on airplanes, the boat lay in a roll and it had to be taken into account). Changes were made to the design of the hatches on the wheelhouse, during the test trip, when reaching a speed of 42,7 knots, the cabin hatch (not the main passage hatch) was torn out, and further on the boats of this project it was forbidden to exceed the speed of 42 knots.

    The alloy in the primary circuit is lead and bismuth.
    How exactly lead is circulated in the primary circuit is completely irrelevant. The important thing is this: the pressure of the medium in the first circuit was half that of the second (about 20 kg / cm2 and 42 kg / cm2). But in water-cooled reactors the opposite is true.
