Cable winding has become redundant: a new approach in military shipbuilding

Example of a ship's hull cable winding

Many inexperienced readers wondered what they girdle warships at the stage of fine-tuning, when their transfer is approaching. the fleet... This process is called ship demagnetization, which increases protection against sea mines by reducing the magnetic signature.

Until recently, it was customary to resort to demagnetization by stationary installation of cable windings on board. However, the Australian company AMRA, which works closely with the French defense company ECA Group, decided to resort to a different technology as part of its military shipbuilding program.

Our solution is a real technological breakthrough because it simplifies the [production] process and reduces the required time

- explained the contractor in this regard.

In his words, the traditional demagnetization, which consists in wrapping the entire hull of a ship or submarine in a massive wire coil and passing electricity through it, has become superfluous. Instead, an innovative approach has been developed. AMRA plans to place the coils on the seabed within a specially designed structure and pass current through it. In this case, demagnetization will take just one day instead of the previous ten, not to mention a decrease in labor intensity.

It's a great collaboration model to help you outrun the competition when it's time to compete.

- noted in the Australian government.

will work, the figly stuck a giant coil to the bottom, and as I understand it, what kind of hydraulics is there to adjust its immersion, is it only needed when the plastic housings are gone?

[Fotoceva62]

Nk finally wrote about my VUS. The technology without winding demagnetization, including by means of windings laid on the bottom, has been known and applied for a long time. There are such stations in Russia. In the Soviet Union, a similar complex for aircraft-carrying ships was going to be built in the region of Cape Margopulo Sevastopol (it's no secret, the methods and norms are the secret).
But it is too early to write off demagnetization by the method of imposing working windings on the object, since in addition to the possibility of demagnetizing vessels to deploy the stand in any suitable anchorage, there is also
a lot of features ... In the photo is the first "Wed" pr.130 at the KChF.

The Germans who came to my dacha several years ago were shocked when, after the fireworks, sitting at the table, I told them that I made the fireworks myself from what was sold in the hardware store. Mom, that evening, part-time "worked" as a translator, then said that they had somehow become wary of me and whispered about something, glancing at me sideways. For a terrorist, perhaps? Ordinary Soviet childhood, ordinary military service - no terrorism.

For them, this is a very serious discovery. When they say that explosives can be collected by buying everything in a household chemicals store, for some reason they think that all Russians have such knowledge.

Aircraft modeling circle, two years in the "Center for Children's Creativity" ("treshka" with a separate entrance in the "Khrushchev" near the school). Actually, aircraft modeling did not appeal to me - I considered cord models as bullshit, and large-scale ones - too slow a result. It was boring to sharpen the plane for the IL-2 for two weeks. But the "rocket modeling department" turned out to be mine. All the guys in the yard respected the "scientific" approach to "explosives".

[Real Pilot]

Interesting! Hopefully, we will also conduct appropriate tests.

Although it seems to me (I am not a sailor, but simply an engineer) that such a system could be provided for permanently installed on the ships themselves. Insert the insulated wire into the casing, and either place the electrical part of the system on board, or on the quay (for smaller hulls) or on a special vessel. This would not be an expensive solution, but it would allow ships to be demagnetized right at sea autonomously.
And it would save resources and time at the base.

Don't worry, Australians are catching up in this matter

[AVA77]

Alas, but a patent for an invention does not shine for you Your idea is correct and has long been implemented on the nuclear submarine of pr.671RTM and the fick knows it on what else. A RU-S / 45 demagnetizer is installed on the submarine to protect it from non-contact and induction mine-torpedo weapons based on the use of a magnetic field, as well as to protect it from magnetometric detection equipment.

already ... It is called RU. For processing, a large mass is not very rational. It's wiser to build a stand.

Gryat, the famous Philadelphia experiment, is when ufologists saw the demagnetization of a destroyer.

[Pechkin]

I even imagine how some journalist passed by and asks what are you doing. And the military: we demagnetize the ship is protection from mines. Journalist: how does it work. The military: well, the ship does not seem to see the mines. Journalist: you make an invisible ship. ! Military: no, it just doesn’t magnetize. Journalist: you make an invisible, non-magnetic ship !! Military: get out of the door. The next day, there’s a military experiment, invisible ships !!!

[mat-vey]

Kurchatov was engaged in demagnetization when he was made the chief on the atomic bomb ...

[Aviator_]

He did this from 41 to 42 years old, and successfully. Then - the atom, to I.V. Kurchatov, as a skillful organizer, was pointed out by Ioffe, who by this time was already old, but knew his students well.

[Fotoceva62]

These issues were dealt with in the First World War. And during the clearance of the Northern Dvina, which the British blocked with magnetic mines.

[Aviator_]

Of course, you can do it. As far as I know, the effectiveness of British mines with magnetic fuses on the Northern Dvina was zero.

Soviet, mind you, textbooks. American people don't write about such complicated things.

My mother worked all her life in a pedagogical university, she told me that in the same America, the learning process is absolutely opposite to ours. In our country, if not everyone is mastering the program, they "pulled up" the laggards with voluntary-compulsory electives, additional lessons, etc. In America, they simplify the program, aligning themselves with the laggards - so that everyone can learn.

Hence the difference in educational level.

Recently I watched a 2011 American film, shot by a Georgian, about how two girls and a guy were accidentally locked in a sauna. The girl in hysterics demanded that the guy explain what would happen to them if they sit for several hours at 120 degrees, what is "heatstroke" ...
I understand that American textbooks do not write what will happen. And there are no photos. They don’t write in ours either, only our young people in their 20s for some reason know what "heatstroke" is, but in America they teach this at universities?

Never mind, another 10 years of "reforms" in education - and we will have the same thing.

[ghby]

Not everything is in reforms, or rather, not all reforms can spoil. It's also about natural ingenuity and curiosity. And by the way, there is an interesting series of educational cartoons just developing interest in physics - Smeshariki: Pin code. My first grader loves to watch, and then shock grandmothers by explaining or asking them something from the series: where does the electron run, or about a beam of photons (illuminating the wall of a neighboring house with a flashlight) and so on.
In America, education is sharpened on the show - they are trained in this self-presentation, and the rest is the lot of emigrants.

[Ryaruav]

that there was no information that someone died from magnetism

[rocket757]

I can say ... rough, but simpler. Try sticking your head into an industrial demagnetizer that is supposed to demagnetize a huge metal structure.
And so small such devices are used to treat joints "the CORAL device) ... in fact, a transformer with an open magnetic circuit! I demagnetized hundreds of CRTs like that.
As always, in small doses and with poison they treat, and in large, i.e. with a high intensity of the magnetic field, with an increase in the frequency of the alternating current, everything will become much more dangerous.

You can wind it yourself, it's not tricky, it was easier to take a standard coil from a starter with a magnetic core, fold the moving part and the demagnetizer is ready.

[Zoldat_A]

Yes, winding up a simple matter, but the neighbor was a TV master in the state television studio. It’s somehow undignified to go to apartments for calls with homemade products. And, judging by the fact that he himself told my father about the specifics of his work and the fact that he had the first Zhiguli (VAZ-2102) in his entrance even before the Olympics - he could buy such a device for his own money, although they were given out at work.

[rocket757]

Everyone did their best.
I had to make a similar device / stand for demagnetizing the TEZ, in which the feride switching elements are installed, although this was not provided for by the standard package.

[Mavrikiy]

Until recently, it was customary to resort to demagnetization by stationary installation of cable windings on board.

What a nonsense. During the Second World War, battleships were demagnetized and so on. What are the case windings? The whipsaws have stolen something again and pass it off as their genius.

[Alien From]

They will fry a lot of fish this way)

[rocket757]

No, HDTV is needed for frying! And so that it does not run away, it will simply rest. Those. the process will be accompanied by the stench of rotten stuff.
By the way, the rate of demagnetization depends on the intensity of the magnetic field, i.e. from the strength of the current, and not from the fact that the coil was shifted differently.

The mechanic simply did not tell you what they were doing)))) There are windings inside the ship hull and the demagnetization system works according to the earth's magnetic field, tk. depending on the latitude, the magnetic field is different and the demagnetization system changes the ship's field. And on the barrels, the current magnetic field is measured. If it is not possible to expose the ship system, then they are wrapped with cables as in the photo. So faster and in my memory it took only one time. Usually, after the delivery of the ship, if the iron has not been changed much in it, the ship's demagnetization system is enough)))

And here mines, demagnetization, girdling (I especially liked it) ...

We call it a demagnetization stand, and these stands have existed for 60 years already. In the Navy, a similar process is called to stand on a pit, ie. for demagnetization using the stand.

[Lex_is]

More than 60. Back in the Second World War, stands were used for submarines.
Only until now both methods are used.
The winding-free method has its drawbacks and does not always succeed in achieving the required result.

It's that simple! there is a problem and I say there are solutions to a completely new level: a simple device that reverses polarity when the ship's hull is ionized.

[Anchonsha]

But the simplest proposal is that you do not need to wrap the case with cables, and even more so for demagnetization, you can do just one day. And sometimes it is necessary to demagnetize only a separate part of the case, sometimes because they are not metal parts.
