American experts laughed at the Chinese submarine project, which will reach speeds above 5 thousand kilometers per hour

Last week, Chinese military designers announced the start of work on the next generation submarine project, which will move at a speed of more than 5-th thousand km / h. According to them, she will be able to cross the Pacific Ocean (from Shanghai to San Francisco) in 1 an hour 40 minutes. American experts called the project ridiculous. Reports about it Gearmix, with reference to the site of the English edition of the Independent.

The publication explains that "the new submarine will work on the basis of supercavitation - a method of accelerating underwater movements, which was first developed by the Soviets in the 60-ies, but so far applied only to torpedoes."

It is reported that "the method is implemented using a special nose fairing that creates a gas bubble that surrounds the vessel, and since the air is less dense than water, the vessel, while in this bubble, can move faster."

Nevertheless, the implementation of this method in practice is extremely difficult due to technical problems related primarily to the control of the boat (water is needed for the rudders) and air compression in the bow of the ship at such speeds.

“But the very thought of submarines with nuclear missiles on board, capable of circling the globe in half a day, is staggering”- writes the author of the publication.

According to the newspaper, "so far one of the fastest torpedoes working on this principle - the Soviet" Squall "- develops the maximum speed in 416 km per hour, and the speed of the modern German torpedo" Superkavitierender Unterwasserlaufkörper "does not exceed 450 km per hour."

Chinese researchers, on the other hand, claim that their management team decided to create a “liquid membrane with varying friction in different parts of the vessel.” According to scientists, “combining liquid membrane technology with supercavitation can significantly reduce launch problems and simplify ship control at cruising speed.”

American weapons specialist Norman Friedman, in turn, points to the fact that "even supercavitating torpedoes are good only for a sprint and are not able to swim further than 3000 meters." According to him, “for submarines, this range can be extended to 72 km, but a sharp increase in the distance and speed of movement seems to be a transition from scientific research to science fiction.”

If you did not know about the Shkval torpedo and you would be told that under water you can move at a speed of 500 km / h, I think the reaction would be the same. The Chinese, at least, are not going to build a starship, and there is a medicine provided for cutting the budget dough - a pill weighing 9 grams for intracranial use.

Here is another question, imagine that something weighing several tens or hundreds of tons is moving under water at a speed of 5000 km / h, the question is backfill: what height will the wave be on the surface of the ocean? and how much will this boat be invisible?

and a cut is provided for a budget dough - a pill weighing 9 grams for intracranial use.

Such a "medicine" can and does work, but not always as prevention.

[dr.star75]

5000 km / h is probably a fantasy, like a manned expedition to Mars, but if they reach an underwater speed of at least 100 km / h, there will be a breakthrough, then sshamam will no longer be laughing

[severniy]

Yes, and develop 5 tyr mona, we’ll plant it in the engine compartment .... say half a billion fighters, the transmission system of stars from the shimano, and .. oppa !!! so it’s possible to use it as they say ...

There will be no wave.

[Wedmak]

Are you talking about a circle on the water? So this is a shock wave, it moves at a lower speed.

[iConst]

Americans just torn their stomachs when they heard about the Flurry. When it was confirmed, the grin became crooked.

But here, when you consider that the submarine will be inhabited - I think the Chinese have overdone it. Or a new variety of tea was bred - abruptly dill dill.
The point is not even the technology of achieving such a speed - combat fighters have buried themselves in the "ceiling" - the overload on the pilot has already reached the limit of even a trained person.

Imagine that on the way of such a boat there will be a major hindrance - an undead sperm whale.

Let's just think about it. A submarine is not a plane. By the way, planes do not fly at that speed, and they don’t have to bother with the carpet!
Well, let the underwater displacement be 1000 tons. Let them decide the issue of management and cover. Fuck with him! Those. we have the air resistance that this thing overcomes in motion.
Do you have physicists? Who will calculate what engine power should be, so that a canoe with a mass of 1000 t moves at a speed of 5800 km.h. in the air? This engine is definitely not a screw or water cannon. At the moment - only a jet engine.

Calculated power? Now calculate how much rocket fuel is needed for this engine to work for at least an hour!

Now, as far as I know, the only engines capable of such a speed are direct-flow reactive and rocket (two boots are a pair, in general). But the first starts to work at a speed greater than 3000 km / h, and the second should, in addition to fuel, have an oxidizer reserve. So neither one nor the other will work again.

[arane]

In fact, I meant the second, fuel + oxidizer. All right. It’s difficult, a lot, hard, voluminous and dangerous.

Yes! But the turbo-fuel supercharger in such rocket engines still work on the physical principle of operation of the propeller. And the propeller has the limits of its indestructible rotation, and depends on the radius thereof. Therefore, the key task is how to overcome these non-destructive limits of rotation.

[Wedmak]

Fuel is also different. You can supply fuel simply by pumping pressure into the tank. There are many ways and without a screw.

A squall with a diameter of 533,4 mm, that is, there will be a collapse, but small. As well as "waves", diverging from this collapse, compression sections. Now imagine the collapse of a tunnel 5-6 meters in diameter !!! ALL sonars will go deaf and die, fish will float up belly, stunned animals will drown ... And if such a submarine passes along the coast? This is almost the same as an earthquake, a tsunami is provided.

[Mol]

It is also interesting how a submarine will maneuver at such a speed ?! Or do the designers plan that the boat will sail only along the shortest route, in a straight line from point A to point B ?! The boat lay on course, the Chinese engines cut engines at full power and flooded ahead without turning anywhere ?! What if, as IConst wrote above, a sperm whale appears on the submarine's path? Or another large sea dweller? A submarine of a potential enemy ... I can imagine an attempt to make an unexpected sharp maneuver, avoiding a collision, a turn. "Fast and the Furious" is resting!

Do not believe in the Asian yellow genius!

[arane]

Absolutely in the hole! Here is another important point. This figovina will (I'm sure that will not be at all) fly at a shallow depth, because gas generator to create a carpet must overcome the pressure of water. With increasing depth of immersion, the power of the gas generator (and, accordingly, its size) will grow exponentially.
At this speed, before collapse, the pit will be there to the depth of immersion.

just about here! Close to the topic!
In fact, there is really no suitable engine right now. If anyone has heard - tell me? .. But you can consider the option of using water as a "working fluid": the jet stream from the rocket engine heats up the water entering the "combustion chamber" through the ejector, and then the superheated steam, together with the plasma from the RD, through s / s nozzle flies "back"! That is, we get a jet water cannon, by the way, with a sickly thrust! Not very scientific - but similar developments have taken place. Another thing is that it will hardly be possible to accelerate this jet to 5000 km / h
Or maybe everything is easier ?! Maybe the Chinas have opened anti-gravity ?! Then they have problems maneuvering on the drum! .. True, it is not clear why they need a submarine then? ..

Nope, I think they got to the book "The Secret of Two Oceans" - a science fiction novel by Grigory Adamov.
Quote:

Krepin was carried away by the idea of ​​increasing the speed of movement of the "Pioneer" by covering its body with something like slime.
However, if it were possible to cover the surface of the "Pioneer" with artificial
mucus, anyway, it would be continuously washed off with water. After a long search
Krepin found a completely unexpected way out. In cases where necessary
was to reach especially high speeds, he surrounded the body of the "Pioneer" instead
mucus with a layer of hot steam. Using your inexhaustible reserves
electricity, "Pioneer" with its help heated the entire outer hull of the submarine
to a temperature of two thousand degrees. At this temperature, a small layer
the surrounding water instantly turned into steam. Due to fast movement
submarines more and more new layers of water came into contact with her
a heated surface, continuously creating a continuous around it
gaseous shell. This eliminated the friction of water and friction arose in
gaseous medium, the density of which, however, was more significant than
the density of atmospheric air, but many times lower than the density of water.
Steam forming around the submarine as soon as it moves away from a given point,
immediately cooled under the influence of ambient low temperature and
turned again into water, not reaching the surface, in the form of bubbles.

Read, the described submarine is absolutely fantastic. The Chinese are resting.

[gridasov]

water, as soon as it starts to move, begins to form jets. In a turbulent flow, nodes are formed at which the flow direction changes from the compression vector to the expansion vector. This causes cavitation. So here between the layers of water there are break-in layers of a rotating stream, which allows the cavitation-free flow of some layers in relation to others. Therefore, in fast-floating and others, the surface layer is always wet. Technically, this is not very difficult.

I argue because the question is not the wetness itself, but the fact that a highly dynamic layer of water does not form a polarization with a layer in the body. The surface of the outflow is not in direct contact with the water layer in which the compression and rarefaction region is formed. If in a barrage cavitation is created by a finely dispersed known substance in contact with water, a chemical occurs. reaction, then there is a so-called. a turbine that allows in the compression area in front of a boat or aircraft to perceive and concentrate the flow in such a way that the flow around the surface of the object increases. Remember Schauberger. Only Schauberger has no algorithmic solution to use the Coanda effect. And he is very necessary

Everyone knows that when a liquid or gases flows along a metal surface, it sticks corny. However, this is evident only when the liquid breaks off this surface. Studies show that any liquid or gases ionize the surface of the outflow. And we figured out how this happens vectorically. That is, how the liquid jets are defined so that they create a polarization between the liquid and the surface. But in turbulent high-potential states of the flow of the stream, there are algorithmic differences depending on the remoteness of the layer from the surface. Complexity also considers such a relationship of simultaneous changes in the level of polarization on the surface of, for example, a screw and simultaneously in the fluid flow. That is, at each point of a certain space of a liquid, transformations occur, which are also determined by the composition of the substance of which this liquid consists. So, in fact, the most highly ionizing surface of the outflow is liquid metal. Does he even know how the substance of this liquid metal cavitates? One can only assume what the potential difference will be on the blades of the turbine we created if this substance of the flow is in the closed loop of the ionizing surface. I hope I just made it clear.

[Wedmak]

Nifiga is not easy. Either I did not finish my studies at the university, or you operate on higher matters. True, we did not have aero- and hydrodynamics. Apparently from there all these obscure phrases.

I do not blame anyone for not perceiving what I'm talking about. The fact is that understanding the very essence of the organization of a new algorithmic process is preceded by the formation of a highly productive analysis. In order to discover something new, at least it is necessary to have comprehensive information about absolutely all the studies of scientists throughout the entire existence of man.

[gridasov]

Do not think so. The whole topic of the discussion addresses the issues of highly dynamic high-capacity physical. processes. But the analysis is carried out by each as a static or laminar process. Understand that cavitation is a part, it is a short period of transformation of the flow and substance of the medium. It is part of a complex of all changes and transformations not only in the medium, but also on the surface and inside the object. Therefore, the completeness of the analysis can be ensured by a mathematical method identical to that going on. Therefore, in order to create something effective, one must first possess the mathematical tools of such a complete and highly dynamic analysis.

[pilot8878]

The question arises: what is the required propulsion power? Take an interest in leisure, what is the thrust of fighter-interceptors, of missiles. Calculate the ratio with body weight and take into account the resistance of AIR, and not much denser water, which, even with a bubble of air, even with your chest, must be pushed.
And so yes, the news amused.

[Vasek]

Quote: pilot8878

propulsion power?

and what is it measured in?

[gridasov]

The axial shift of the shaft pump at a known capacity of about 10 tons. This is not to mention the reaction of the output stream. So that is quite comparable with the most efficient aircraft engine.

So where, after all, is the "propulsion power" measured?

[gridasov]

It seems to me that it’s more logical to choose not the measure of power, but what kind of potential the mover forms at the input of the moving flow and at the output and in relation to this medium

[arane]

Well, give the answer, what is the minimum diameter at maximum speed (you should not forget cavitation) to have a propeller to create the necessary output power for the movement of an object weighing 1000 tons at a speed of 5800 km.h.

If you are going to row a screw ...
And yet, offhand, when transmitting torque to such a screw from the motor shaft, it is not the screw that starts to rotate, but the object itself
Although, you can solve the problem with a coaxial screw of different rotation or two shaft lines

[Vasek]

Quote: arane

You can solve the problem with the coaxial screw

Most likely, at those speeds, you should forget about the screw in general.

The Chinese invented gunpowder.

The fact that it was invented by the Chinese has long been questioned. The idea of ​​China's primacy in the invention of gunpowder was thrown in not so long ago. In 1956, Professor Feng Jia-shen (People's China Journal, No. 14, July) reported that the Chinese physician Tao Hong-ching had studied the burning of saltpeter at the turn of the 5th and 6th centuries. However, Joseph Needham, who at about the same time wrote the book "Four Great Chinese Inventions", did the most to popularize the Chinese priority. It was in this book that the theses that the Chinese invented the compass, gunpowder, paper and printing earlier than anyone else were most widely voiced ...
At one time, Noel Joseph Terence Montgomery Needham was a British "generalist" in 1965. Together with diplomat D. Brian, he founded the "Society for Anglo-Chinese Understanding", which during the years of the "Cultural Revolution" helped British citizens to visit this country. These visits of certain subjects of Her Majesty to communist China are all the more interesting if you remember that even for Soviet citizens the fraternal country was tightly closed in those years. That's when they "invented" it on "invented" paper (recall the Sumerians ) not without the help of the individual submitted to the queen. Not only that, we recall the famous Chinese scholar with a capital letter, he is also the revered Chinese god La Madou, thanks to whom the Chinese learned about the great inventions of Europeans - mathematics, astronomy, etc. But about the great inventions of the Chinese: gunpowder, paper, a compass, this scout missionary, Italian Jesuit Matteo Ricci (in the form of the god La Madou) for some reason did not write anything ... Well, the last nail in the lid- The opinion of chemists is uncompromising: neither material , nor reliable documentary evidence that prior to the 15-16 centuries. at least somewhere (not only in China) they knew how to make gunpowder, no. Deposits of nitrate are rare, and potassium nitrate, necessary for the manufacture of stable formulations, DO NOT MEET AT ALL. The manufacture of potassium nitrate requires technological methods that appeared only with the development of chemistry in the 15-17 centuries.

They are talking about speed, and not about real use ... Although noise will not play any role for such speeds, because you can intercept it, the shock wave diverging in circles from the hull of the boat at that speed and collapsing at its conical stern or immediately after it, it will be even faster to push it forward, such as an additional water hammer :)))
But in general, one can praise the idea and the attempt to implement it, it will be a pity only the crew ...

[Ryndabul]

For long distances, I agree - bullshit, but if the idea is implemented for short distances, even 3-5 miles, then this is serious: bounce - hit - and leave the point of contact. And, as I understand it, the Germans are already developing the development, which means ours in the subject. There is no question: who was stolen)))

German von Braun sent them into space, a Russian Jew Rosenberg made for them, a Russian Sikorsky helicopter, according to the formulas of Ukrainian Kondratyuk flew to the moon ..., here the nuclear bomb was bombarded under the leadership of the American Oppenheimer, and even then with a motley company! And now the flagship Apple telecommunications where to collect? In China!

In any case, if this is not a mistake in order and not a simple bending of fingers, China will have technologies for the future

[gridasov]

And why is it so difficult to understand that any object in nature has a certain external potential, and therefore there is also polarization with the space of the external environment. This means that if a generator works in the range of a given parameter, then it will be determined not by sending an impulse and receiving a reflected one, but only by taking it. And such a generator has long been known.

- what will she do if she suddenly jammed the steering wheels for a dive?
- what will happen if a submerged object, a sperm whale or some other underwater obstacle gets in its way?
- how to use weapons at such a speed? means of communication and navigation?
- What do you think: at what distance SOSUS will hear this miracle of underwater engineering?
- (they already asked about the crew’s well-being, I won’t repeat myself!)
- Do khinchiks have an anti-gravity device? if not, what kind of power does the engine need to provide such a speed?

The Chinese are cunning. They are silent about the fact that not cavitation will be used, but the annihilation of space - the "transformation" of water into a saturated (not absolute) vacuum. For this it is necessary to construct a dynamic matrix with directed electromagnetic structures. If they succeed, then it will be possible to literally fly under water at a speed higher than stated. And let the Yankees laugh.

Colleague, let's get back to the definitions of science, not fiction.
Annihilation is "matter", not space. It is based on 100% reaction of matter and antimatter with a colossal release of energy, transformation of the original matter into energy and other elementary particles.
"Space-time" can be bent, they can pass one into another, but they cannot be destroyed! So the annihilation of the "Space-time" continuum is canceled for now!
Then, space is not water! (substance!) as you deigned to express yourself in your post.
To the question of vacuum. Vacuum - (simplified) airless space (space free from matter) cannot be saturated! This is already a rarefied air (underwater?) Space with a certain content of substance molecules. Thus, the very concept of "vacuum" loses its physical meaning.
Sincerely.

[gridasov]

absolutely right - no air. BUT what is there if there is no substance that creates both radial pressure and qualitative properties

When the same joke, albeit funny, is repeated many times, it becomes no longer funny...
It has already been explained that at such a speed, the density of water in the boundary layer will be a conditionally hypothetical material denser than armor alloys (a shameless exaggeration, but still). How to cut it, and at such speed? The next point: we cut it in a straight line... and now we’ll cut it along a curve (will we turn? Or until the first stone?), well, well... Next, what about the crew of the miracle projectile into artificial gravity capsules when turning? Already invented? Even without theoretical justification? Let's move on... Are we going to navigate the surrounding space? Yes? But as? Through 2 environments with known (and more or less constant) characteristics into a 3rd environment with variable gradient characteristics? There is no other way to scan with telepathy...

[Darth Revan]

Technologically, the idea is absurd. I remember a few years ago watching a program from the series “Fantastic Projects”, I think that’s what it was called, and they talked about a project that seemed absurd to me - a Transatlantic underwater tunnel in which trains from New York to London would travel in 1 hour, because the - ATTENTION! - they would move in pipes, inside of which there would be a vacuum. The idea is stupid - how much money should be spent on such a miracle, and from a safety point of view it is nonsense - if a train gets stuck in the middle of the ocean or accidentally breaks a pipe, what then? It would be better then to create stratospheric passenger aircraft. So - isn’t this what the Chinese had in mind? But I don’t know how you can enclose a submarine in a bubble from a vacuum. In general, it’s just some kind of nonsense.

[korjik]

Well done Chinese! they won’t build it, they won’t build it, but they stirred up the people, I’m already counting how high the wave is, how much fuel is needed? It’s like in the joke about a fisherman and an abandoned fishing rod on the shore.
No one has taken a bite in the river yet, but this is the fifth time.

[Cristall]

Of course, they may have bent about the parameters..
But the idea itself is not new to me. I expressed it a year ago, having become acquainted with the work of the Kyiv Institute (work on supercavitation)
I can well assume that the people of Kiev offered services to the Chinese to create super-fast boats.
This is technologically feasible - but there are various problems. And the parameters indicated in the article clearly exceed technological capabilities so far..
In general, the idea itself has been expressed; all that remains is to convert it into metal, at least as research.

[Aleksey_K]

I wasn’t too lazy and went to the GearMix website. There is no link to the British independet, but there is a link to the Sploit site, and this is just a discussion blog “SPLOID is a new blog about awesome stuff.” The article on this site was written by some Omar Kardoudi without any reference to the source. I think this is still fantastic. When Jules Verne received information from the future, he couldn’t even declare it, so as not to be branded as crazy because... then his human career would have come to an end. And therefore he described information from the future, in the form of fantastic adventures. But this is acceptable and everyone considers you normal. And as for the exorbitant speed in water, I will say that this is possible by somehow moving apart the layers of water, creating a vacuum in which it will be possible to develop cosmic speeds.

[Everest2014]

Quote: Boa constrictor KAA

You can still ask questions, but I think this is enough.

The submarine received the coordinates and, with its mind-blowing speed, moved to the point of a possible attack, hit it with former Soviet jet torpedoes and also rushed off into the unknown depths of the oceans. What if it has nuclear weapons on board? This is the nightmare of any defense. Considering the speed of its movement, it is not afraid of submarines and other ships designed to destroy the underwater vehicles of their possible enemy. In short, if such a Frankenstein existed now, the seas would begin to be littered with mines for every fireman. And, the titanium hull for such boats was made by the USSR; it will hit a sperm whale like a bullet.

Just don’t think that she won’t walk at normal speeds, she will, she will.

[Dejavu]

In principle, if you tie a Chinese to Shkval and call it a submarine, it might work :)

[asdasdz]

If they suddenly manage to achieve such a speed, then they won’t care about handling and how the crew will feel. They will simply equip the submarine with a nuclear charge and send it on a direct course towards the target. You could say a long-range nuclear torpedo)

[kostyan77708]

There will be no wave. But this is nonsense! By the way, I shot a barrage.
Let's just think about it. A submarine is not a plane. By the way, planes do not fly at that speed, and they don’t have to bother with the carpet!
Well, let the underwater displacement be 1000 tons. Let them decide the issue of management and cover. Fuck with him! Those. we have the air resistance that this thing overcomes in motion.
Do you have physicists? Who will calculate what engine power should be, so that a canoe with a mass of 1000 t moves at a speed of 5800 km.h. in the air? This engine is definitely not a screw or water cannon. At the moment - only a jet engine.

Calculated power? Now calculate how much rocket fuel is needed for this engine to work for at least an hour!

so maybe the length of the submarine will be 500 km, the engine will be 499,8 km, and everything else will be 200 meters)))))))

How can one maneuver at such speeds, that is the question.

[smershxnumx]

Quote: Canep

Here is another question, imagine that something weighing several tens or hundreds of tons is moving under water at a speed of 5000 km / h, the question is backfill: what height will the wave be on the surface of the ocean? and how much will this boat be invisible?

I think it will not only be visible right up to the horizon, but also heard at the same distance

[Temer]

[Fantazer911]

Sorry for the rambling.
Heating a vessel in order to reduce the friction force under water is economically costly and not feasible, high costs in energy and heating area as well as cooling, cavitation process
vaporization and subsequent
condensation of steam bubbles into
fluid flow,
accompanied by noise and
hydraulic shocks,
formation in liquid
cavities (cavitation
bubbles, or cavities),
filled with steam itself
liquid in which it occurs.
Cavitation occurs in
as a result of local decline
pressure in the liquid, which
can occur either when
an increase in its speed and an increase in the flow of liquid is a turbulent regime of liquid flow or a laminar regime, the first is fast and the second is slow, I think that the maximum for a submarine is no more than 500 km per hour, although at such a speed problems may arise if the speed is higher then How are they going to hold the so-called bubble? for sliding, its separation is possible because it is not taken into account that there are different densities of water in different layers.

[Grandfather Victor]

Moving in a gas rather than a water environment, an object must create lift so as not to sink to the bottom along with the gas bubble. For a torpedo this can be done by giving it the appropriate shape, but what about a submarine that has a huge mass?
