Spain has completed tests of its own anaerobic unit for diesel-electric submarines

Project S-80 lead submarine at Navantia in Cartagena


The latest Spanish submarines of the S-80 project will receive a non-volatile power plant (VNEU). This was reported by the press service of the Spanish shipbuilding company Navantia.

According to published data, Navantia, together with Abengoa, completed a test program for a promising anaerobic power plant designed for the latest Spanish diesel-electric submarines of the S-80 project. It is reported that enterprises are already preparing for serial production of the installation. The first VNEU will be installed in July 2021 on the third Cosme Garcia submarine under construction, Project S-80. The first two submarines of this project will be built without VNEU, the addition of the system will occur after the introduction of submarines.

The Spanish non-volatile power plant for submarines of the S-80 project is based on the principle of bioethanol decomposition (BioEtOH) in special reactor processors with the production of high-purity hydrogen. The resulting hydrogen, together with oxygen, is supplied to the fuel cells. Oxygen is stored in liquid form in a cryogenic high pressure tank. The carbon dioxide obtained during the decomposition of bioethanol is removed overboard in a mixture with sea water.

The declared power of VNEU is "not less than 300 kW", and the duration of the stay and the course of the boat in the underwater position should be 15 days.

S-80 project diesel-electric submarines are 80,8 meters long and 11,68 meters wide. The displacement of ships is 3 thousand tons. S-80s can reach speeds of up to 19 knots. The submarines are armed with six torpedo tubes of a caliber of 533 mm for torpedoes and anti-ship cruise missiles.

In 2004, the Navantia shipbuilding company pledged to build a series of new submarines of the S-2 project for 80 billion euros in order to replace 4 diesel-electric submarines of the Agosta type of the Spanish Navy. The delivery of the head submarine was planned in 2011. However, miscalculations in the design led to the weighting of the submarine and problems with the ascent. Due to financial and technical problems, the construction of boats was delayed for a long period, and their planned cost increased from contract 1,756 billion euros to the currently planned 4 billion euros.

        In lighters, a closed-type diesel engine was with a pile of related problems and still undeveloped technologies.
        Here the reaction of cold combustion and low-power installation. Cryogenic oxygen can also be kept overboard in the superstructure of the lightweight body or baffle.

      At least we don’t have such “overlays” as the submarine’s drag on 1500 tons. with a shift of the center of gravity in the stern, plus a roll on I don’t remember which side. laughing
      Based on their problems with weight and weight distribution, it would be naive to expect the imminent appearance of submarines, especially with VNEU. And advertising is always faster than thought laughing This is evident by the stupidity of the videos.

          Either put on your underpants or take off your cross and don’t worry. All the same, there are more "dunduks" in the world and they are not interested in the fact that in road accidents they die more than from the same war in Syria or Caucasus.

        Americans do not build them at all. Neither diesels nor VNEU. Rented (like the Swedes), ride and spat. 300 kW - these are only trolling engines. Creeps slowly for 15 days. Full speed is still from the batteries, it means not for long. The Japs came to the conclusion that the section with additional batteries with the same weight and size gives almost the same effect without problems with liquid oxygen and the entire coastal infrastructure for its receipt and refueling. Dead end. It is ridiculous, but the Germans came to the same conclusion as early as the 43rd year, remodeling Walter’s boat from VNEU to the usual famous diesel engine of the 21st type. The prototype of modern diesel engines.

          Project 613 E. Katran. VNEU based on ECG. You can type in the browser, there is information on the Internet. All tests, including state ones, were completed in 1988-1989 and were considered successful. Underwater autonomy at a low speed of 2-3 knots was up to 4 weeks.

            just somewhere long ago, I don’t remember even which author I read that we still had post-war projects with VNEU. based on the acquired German projects. however, we did not begin to build such ones - we took the path of the nuclear power plant.

    Carry a liquid oxygen tank with you. A finished component of an explosive called oxyquiquit. Adding ANY organic matter makes an explosion. War is also bombing. Shaking can do what depth bombs did not.
    A dubious advantage in terms of guarding the bases and the coast from enemy glands. Is 300 kW scuba diving a 5 knot move? Who will such a boat be hunting for? To hobble to the base when no one is chasing and bothering ....

      You won’t believe it, but there are a lot of things on the boats that can explode. Torpedoes, rockets for example. And cryogenic oxygen can also be stored in the superstructure of the light body, outside the durable.
      And 5 nodes for NAPL is very decent. More often at 2-3 knots they are drinking.

            Yes, it’s clear that not in barrels tied with ropes to the body laughing
            It’s just that if the installation is so complicated, then it probably makes sense to protect it from high overboard pressure, and then either build a second strong oxygen housing, or, well, don’t leave oxygen inside the main durable housing.

              There is an option with placement inside a durable case. But high overboard pressure is not an obstacle. Outside of a durable case, a lot of things are placed. Ballast tanks, missile silos and launchers, partially torpedo tubes, heads or fully retractable, depth rudder drives, auxiliary electric motors, etc.

        Nuclear Submarine S80 (SPAIN) NON-NUCLEAR SUBMARINE S80 (SPAIN)

        All S-80s will be assembled at Navantia shipyards in Cartagena. Submarine hull sections will be manufactured by BAe Systems Submarine Solutions. The S-80 diesel-electric submarine has a length of 71,05 m, a hull diameter of 7,30 m with a surface / underwater displacement of 2198/2426 tons. It is equipped with an air-independent power plant (AIP). The crew of the submarine will consist of 32 people. S-80 will be able to remain in the underwater position for up to 50 days and reach speeds of up to 20 knots (37,5 km / h). It is planned that the boats will be equipped with Tomahawk sea-based cruise missiles and 533 mm torpedoes, possibly DM2A4. Lockheed Martin, Kensberg, Reyteon, STN Atlas will take part in equipping the new project diesel-electric submarine with control systems and weapons. Recently, UTC Power has received a fuel cell contract for the S-80.

          Colleague! I beg you: be more critical of what the media write.
          It was expected that with a non-volatile engine the boat could be under water without surfacing for up to 28 days, however, in reality this indicator does not currently exceed a week. (Oh how!)

          Well, the Germans are "engineering", and then they have 212 dives for no more than 25-27 days.
          The second one. Nowhere is it said about the depth of immersion miracle sub! But it is unlikely that it will be more than 300m.
          Power of the power plant = 3600 kW (3 units x 1200 kW), plus 2 grams of battery for 180 "tanks", a total of 360 elements. Speed ​​also varies. In Spanish sources it is indicated: surface -14uz, underwater - 22 knots.
          In addition to the crew, the NPL can take another 8 people (military personnel). I think - combat swimmers. This is a serious weapon in the warm seas.
          An interesting story with the cost of the project. from 1,75 billion euros, then - 2,135 billion euros, and finally - up to 3, 750 billion euros for 4 buildings and coastal infrastructure.

      That bioethanol, that just ethanol, is one and the same thing. By the way, the "front 100 grams" - this was an aqueous solution of bioethanol, because vodka was driven only from plant materials. And one more thing: this, of course, is not an anaerobic plant, since oxygen is used. Anaerobic are battery and atomic.

      There is more to the question of expediency.

      ours has no analogues

      Well, the basic principle there is not so unique - an electrochemical generator. But the method of producing hydrogen for him really didn’t have analogues in the world fleet - it’s some kind of tricky process that allows you to get hydrogen from diesel fuel directly on board. The idea is good, even great: diesels aboard as you like, know to recycle yourself and use. Autonomy under water, again in theory, was supposed to exceed everything that has already been achieved by competitors. In addition, no additional mechanical noise is assumed during this process, which means (demon) noise is also at an altitude. Yes, it hasn’t happened yet.

      An ordinary diesel engine should float to the surface and rumble on the engines, charging the battery. It does this very often, and at that moment it is noticeable both for PLO aircraft, and for satellites, and for enemy ships. If there is a VNEU, a month’s boat for recharging does not surface and find it much more difficult

        If a diesel engine sits in place without consuming batteries to move, it is absolutely not necessary for it to often float up and charge, and if it has left the area of ​​operation, then you can look for it among thousands of other rattles, it will also refuel there, although there are already three diesel engines more autonomy is enough.

            Greetings hi
            1. VNEU can be installed on a submarine without violating the status of individual water areas. For this reason, our 1144 exited Leningrad / St. Petersburg under diesels. And having passed the Baltic Straits, they passed to the turbine from the PPU-YaEU.
            And the second one. Like Stalin, the goat was a “cow for the poor”, so for some VNEU countries, the nuclear reactor is “cheap”, because VNEU is 4 times cheaper than a nuclear power plant. VNEU is good for boats in the veil, at the turn of the PLO, and the like "ambushes." High speeds are not needed, but “silent glancing” is just that: you quietly charge the battery or you snoop along the line of watch, and at the same time you cannot imagine 3-4 knots for listening to the horizon.
            2. We had a VAU-6, with a capacity of 600 kW, the Nerka project. Maintenance-free small-sized block nuclear power plant with a boiling-type reactor. We converted 651 projects (B-68) for it and she went with the Dollezhal egg in the trial operation of the whole YEAR, and not 10 years, like the 677 project. And from 1985 to 1993 she served faithfully in the composition of the 7th DIP of the KSF (v. Vidyaevo). The car was wonderful for its time. The submarine could go 7000 miles at 4,0 knots! 2000 hours of continuous operation, resource - 12000 hours. Tested to a depth of 240 m while the installation provided the work of 2 GED-s and maintained a speed of 6,0 (!) Knots. It had remarkable weight and size characteristics: dimensions - 6,5 x 2,9 m and weighed only 70 tons. And this despite the fact that the German VNEU on 212 projects weighed 200 (!) Tons and occupied a whole compartment!
            But, in 1993, it all ended with the decommissioning of the BS-68 ...
            This is "se la vie!" - as the brackets say in the "custodian" manner!
            But!

            What am I talking about, a modern submarine that is normally equipped, can only detect an enemy submarine in the main, well, satellites, if the water is very clear, can see up to a hundred meters of depth when they are directly on top (and pointing such permissions is a hundred times more expensive than organizing a point bomb attack), and the boat can also be warned about this if their air is monitored in the area - aviation does not count, the acoustics will detect any anti-submarine ship before it becomes a threat. I don’t know, but if the operation for the boat is being developed correctly, only force majeure is against it, and VNEU does not play a role.

    You won’t believe it, but there are a lot of things on the boats that can explode. Torpedoes, rockets for example. And cryogenic oxygen can also be stored in the superstructure of the light body, outside the durable.
    And 5 nodes for NAPL is very decent. More often at 2-3 knots they are drinking.

    So, you do not know that any explosive has parameters such as brisance, operability and SENSITIVITY. Let us dwell on sensitivity. Measured in centimeters. Tests are carried out on a sample of explosives, 50 grams, a kilogram steel ball-weight is thrown from a height. And when the explosive explodes, the height with which the ball is dropped is measured. So, hydroxyquit explodes on its own. TNT, I don’t know. But, according to the literature, a checker can be shot with a bullet and nothing .... To undermine a mixture of oxygen-sugar, oxygen-machine oil, a slightly elevated temperature is needed. Have you heard of a heap of grain, coal, peat spontaneous combustion? And this happens when the oxygen content is 21%. And here, the local content can easily be 100%. Bondarenko Valentin Vasilievich, a Soviet cosmonaut burned down in a sound chamber. The oxygen content of 35% and accident ruined it.

      Regarding the oxygen content, the most obvious example is probably Komsomolets. Damaged gas analyzer, high oxygen content ... DEPL is even more difficult. When charging the battery, hydrogen is released, which requires afterburning. The combat alert is played while charging. All for an adult.
