Experimental submarine tested in China

The Chinese military conducted the first test of a submarine with a magnetohydrodynamic power plant, working with the use of superconducting magnets to create strong magnetic fields that push the submarine forward, according to the portal www.popmech.ru.

There are no moving parts in the power plant, which makes the submarine extremely inconspicuous.

“This technology was considered promising at the end of the 1980-s - the Japanese Yamato-1 with a magnetohydrodynamic power plant was tested in the 1992 year and reached a maximum speed only at 8 nodes. However, the engineers did not manage to make such engines work on submarines, ”the resource reminds.

It is not entirely clear why this happened - “the probable cause may be the difficulty of creating sufficiently powerful electromagnetic fields for moving ships and submarines at an acceptable speed,” the author notes.

The principle of the magnetohydrodynamic installation demonstrates this video.



Now the submarine with a magnetohydrodynamic power plant was first developed and tested by Chinese experts. Details of the test are not given. It is only known that the submarine "has reached the designated speed" - which one, so far remains a mystery.

"But if China really managed to implement the magnetohydrodynamic technology in practice, it would be a powerful advantage over Russian and American submarines," the publication concludes.

It all starts with the first step and the one who goes comes along, well done Chinese, we need to be very careful with them and reconcile every step we take, but there are many things in this matter ...

[NIKNN]

which makes the submarine extremely subtle.

A moot point. It is difficult to hide the magnetic field, all the more powerful. Plus, I think this masterpiece will revive the development of magnetic mines and torpedoes. And then

There are no moving parts in the power plant

And what will generate electricity, I doubt that solar panels ..

[Teberii]

The idea is interesting, there are questions but answers will come with the time of testing. And the fact that China demonstrates high technology, others will need to think carefully.

Any ideas require attention and study. It is not a fact that they will be used specifically in submarines, perhaps in other industries this idea will be even more revolutionary.

At one time, a rather serious indicator of economy and efficiency was achieved when the magnetohydrodynamic unit was connected to a boiler room. The effect was triple. After burning gas or other energy carrier in the boiler furnace, the exhaust gases (they are ionized) entered the generator that generated electric current, then the gases entered the steam generator of the thermal power station, additionally heating water or steam for heating. It should be noted that in those days the efficiency of such a combination was 65%, and this compared to the traditional efficiency of old boiler houses 50%.

Nirazu worked at MHD there. just like an ordinary thermal power plant.

Interesting news. And this case is not a fake or a publicity stunt?

In general, of course it’s cool, everyone is trying to level the electromagnetic field, for the sake of secrecy, but here it is not necessary to look for it. All loose glands will move in her direction.

The Chinese are still tricksters. They love to mislead the world.

Strong magnetic fields? No, you heard it, a subtle submarine with strong magnetic fields. Only Lavrov with his "D B" and quote after that

Experimental submarine tested in China
It's ridiculous. Do not swim, do not mind. Only what after her electromagnetic trace will remain, and the background, oh mother dear ....
PS. For the first time I saw such a boat in the picture exactly 47 years ago in the magazine "Young Technician".

This article has already been here.
All countries worked with MHD in the 70-80s, and so abandoned it, considering the direction unpromising.
China has discovered these technologies for itself only now and is trying to teach it as "having no analogues in the world."

[Vadim237]

They also promised to create a submarine, with an underwater speed of 5000 meters per second.

[Manul]

And I wonder - where does the electricity come from to service the submarine, charge the batteries, and more? Is good old diesel still in stock?

[san4es]

... a submarine with a magnetohydrodynamic power plant ...

... And what will Comrade say Gridasov? ..

... Alyoyo! ... welcome !!!

[gridasov]

Magnetic force fields are complete abstraction and unreality. Another thing is the properties of magnetic force flows, which form linear, rotating, rolling and, of course, vector quantitative algorithms that determine the quantitative parameters of each point of one or another magnetic force flow. In general, if the Chinese or Russians or Americans don’t know the methods of calculating and analyzing the interactions of magnetic fluxes, then creating something track-like is impossible. This time!
The fact that water and air saturated with water vapor has been moving along magnetic force flows since the 19th century. But how to create the maximum motive force of the water flow through the action of a magnetic flux on it is obvious that no one knows. Moreover, they don’t know how to create a high magnetic flux density of one or another dominant direction, so that there is no breakdown like on a collider. Moreover, fundamentally different induction coils are needed without the parasitic effect of self-induction. In general, the Chinese, like others, are still too far from success ..
It is worth recalling that Tesla allegedly discovered rotating magnetic fluxes, but the Newtonian forms of motion are also a direct consequence of magnetic interactions. But! Tesla did not create induction devices that can replace permanent magnets, but controlled and with a high density of magnetic fluxes.

... Ponyaatno ... But how then is El.Tok?

[gridasov]

I explained vaguely that the field is something so extensible in understanding, and you need specific mathematical parameters that define the field as a complex of those phenomena or properties that are expressed through magnetic force flows. And which have both quantitative and vector parameters as well as potential parameters. Well, what is incomprehensible!? In addition, the electric current is a derivative of the magnetic force interactions and the parameters of the electric current expire from changes in the parameters of the magnetic force interactions. Therefore, scientists cannot understand that the voltage can be "negative" in the vector, that is, its vector will not correspond to EMF or current strength. And build yourself smart and connoisseurs. If everyone knows that why you can’t at least make the induction coil conical, and the Tesla coil inverted. At least they tried it ... Because then the magnetic force fluxes will acquire concentrated parameters alternating with scattering magnetic fluxes.

[Herculesic]

Firstly, this article on the Internet appeared at least a week ago, so the news is not new, and secondly, the MHD generator for a submarine will be heavier than a nuclear reactor, and the boat will unmask the strong magnetic field, I’m silent about the problems when creating efficient, compact, suitable for placement on board a generator submarine - this is work for many years to come!

I don’t understand why everyone was so excited then ...? Yes, the Chinese are doing something experimenting. And what's wrong with that. It doesn’t work out on a submarine that will be used somewhere else .. And as for the problems, whoever doesn’t do anything is not mistaken ..

[win]

I'm already silent about the problems car

That увидеть problems - it is necessary experience MHD generator and propulsion on it.
Here is a boat and an experimental one.
And how long these problems will be solved - that is, experts.

[gridasov]

Rotating magnetic fluxes are not linear - I hope you understand the difference. Therefore, the magnetic radiation of a moving object can be determined only by knowing the algorithms for transforming a rotating stream into a linear vector and again and so on. Moreover, modern devices cannot determine rotating magnetic fluxes because they can be detected only through the break-in moments of rotation of the medium that enters into interaction , but the plane also changes dramatically. Therefore, this is absolute nonsense when they talk about some kind of trace, etc.

[Sergey53]

If you take a closer look, the part before the cabin is similar to the American one, and if for the cabin, it is closer to ours.

[keeper03]

What does this engine eat?!? Ches it all!

[Vadim237]

Atomic pumping.

[gridasov]

What is atomic pumping? Radioactive radiation does not have a high energy density. It is scattered. Therefore, nuclear radiation can only be used to heat water and then, with primitive turbines, obtain a torque on the shaft in order to move in the medium.

[Vadim237]

By pumping, I meant electricity from a reactor turbine.

[gridasov]

Clear! But after all, how many intermediate stages of the direct radiation radiation transformation (we will call things that) to spend energy on the transformation of the potential energy of water, and then lose even more to turn the steam into the energy of the moment of rotation of the generator shaft. to get email energy. Well, only special minds are capable of such algorithms.

[shans2]

China is tying technology from other states, they even leaked f-35s via the US network), but the problem is that they do not know how to create their own from scratch. Most of all, China was lucky with the collapse of the USSR, that is how they got their cruise missiles based on the Soviet X-2000 taken from Ukraine in the early 55s ... and much more, from torpedoes to air-to-air missiles.

[Vadim237]

This country buys, and then patent other people's developments.

And you also need to find out which of these heaps of patents are really breakthrough and what comes of this to serial production.

this will be a powerful advantage over Russian and American submarines

Why would the bathhouse fall?
Well, it will not be echo sounding, but magnetic. if the sound masking of submarines is successfully mastered, then with magnetic seams in general. Again, the speed of movement? Something I doubt that it reaches the same for submarines with a screw or a jet engine.
In general, in my opinion, it turned out something like British scientists in Chinese.

[Former battalion commander]

A couple of spoons of tar in this barrel of honey.
1st spoon. A powerful source of electricity is needed on the boat, due to the very low efficiency of the engine. If you put a nuclear reactor, then there can be no talk of a "small noise".
2 spoonful. The strongest magnetic fields created by this engine themselves are a unmasking factor. Since the advent of submarines, magnetic sensors have been one of the most important tools for finding them. Well, with such an engine they can even detect them from a satellite.
But the fact that the Chinese are investing resources in the search for new products is very, very important. Somewhere breakthrough will happen.

[evaee]

MHD engines themselves can be made in the form of cylindrical nacelles along the submarine (this will also facilitate maneuvering the boat by turning the nacelles), then the magnetic lines will be closed inside the nacelles and will not unmask the boat. When water passes through the gondolas, cavitation vortices can occur that create noise, but there are techniques to deal with cavitation. Those. all issues are resolved, it would be a desire ... and finances. Although the water in the seas and oceans has a different density, the boat, when moving, will shake (as when driving on a hilly road) ... Any movement of the underwater vehicle is based on giving movement to the environment or pushing away from this environment ... So acoustic waves will anyway .. Something I got into a discussion of the subtleties ...

[APASUS]

And will electricity be threshed for this diesel boat? What is the whole point then, but a strong magnetic field is an indicator for the detection of submarines is very significant. No wonder ships still demagnetize

[san4es]

... why can't you at least make the induction coil conical and the Tesla coil inverted. At least they tried it ..

... I didn’t ... I didn’t try ... We must now try.
... What about space and a nuclear engine?

..How long will the ship (the size of a nuclear submarine) accelerate to fly from orbit into deep space?

[Vadim237]

This requires a minimum of two turbojet engines, each equal in mass to the submarine in the photograph, with a thrust of 200000 tons.

[gridasov]

Of course. that did not try. ! You should understand at least why cone coils. It is important to know that fractal email. magnetic processes are due to the fact that in the medium there can be simultaneously short-wave el. magnetic processes and long-wavelengths, which means that it is possible and necessary to be able to obtain those phenomena that we call resonance, such as the processes of intersection of vectors or moments when short-wavelength pulses can transform in relation to long-wavelength ones. Moreover, the capacity of the space that will feed the necessary process is always necessary. Why ion engines cannot develop. There is no capacious process of transforming one state of energy into another (if simplified to say this)
In general, on coils with winding coils, it is impossible to obtain an effective device for receiving electric power. magnetic force flows in the entire range of interaction of vectors.

[san4es]

... you always need the capacity of the space that will feed the necessary process.

... maybe all the same matter (matter) i.e. FUEL, is it necessary to power the process? .. Because. what

the concept involves heating the working fluid with a nuclear reactor followed by discharge through nozzles. The pulsed NRE, in turn, propels the spacecraft through successive explosions of a small amount of nuclear fuel.

These were the Soviet RD-0410 and the American NERVA. They worked on the same principle: in a "normal" nuclear reactor, the working fluid is heated, which, when ejected from the nozzles, creates thrust. Liquid hydrogen was the working fluid of both engines, but heptane was used as an auxiliary substance in the Soviet Union. RD-0410 thrust was 3,5 tons, NERVA produced almost 34, but it also had large dimensions: 43,7 meters in length and 10,5 in diameter against 3,5 and 1,6 meters respectively in the Soviet engine.

[gridasov]

No! Still, the capacity of space. The fact is that space cannot be "empty." Therefore, Tesla talked about the ether. At the same time, the ether is the more enriched the less substance in it. Substances are already derived fractal structures of that primary space in which the algorithms of one or another level of substances are embedded. Therefore, when scientists talk about obtaining an ultra-small particle, one should not forget in space what even smaller, but more energy-intensive components of these particles are formed. But in fact, what they call ultra-small material formations is actually e. magnetic impulses of contact of magnetic fluxes of that which cannot be seen or registered at all.

[gridasov]

It is not a sin to repeat again that the era of spontaneous discoveries is over. You cannot create a breakthrough device with a new quality of the process, if you do not own the theoretical foundations of the justification and creation of such a process. In other words, integrated approaches are needed. And if the Chinese had created something fundamental, then this would have had a complex expression. That is, at first the conversation would be about achievements and discoveries in the field of mathematics and physics, and only then about devices.
