The upgraded version of the "train" "Maglev" in China exceeded a speed of 600 km / h

In the section “Talk about science” today there is a small story about how in China a modernized version of the high-speed Maglev vehicle was tested (using the combination of the words “magnetic levitation”). Usually this vehicle is called a train. It moves along a peculiar magnetic cushion on a special line, which is a canvas elevated above the surface of the earth.

To run Maglev trains, relatively small sections several kilometers long were created. For example, from the airport to the city. Typically, when moving, the speed of such a train reached 431 km / h (in China). At the same time, it could reach 470-500 km / h, but it was deliberately limited due to increasing risks.

The upgraded version of the Maglev is able to accelerate to a speed of 600 km / h and even exceed this bar. The train has already been tested by CRRC Sifang specialists at the test line at Tongji University in Shanghai - the 600 km / h bar was successfully overcome during such tests.

To reduce the risks of getting off the canvas, Maglev implemented the principle of “grasping” its edges. The design is such that, for example, if there is a roll on one side, the system will immediately begin to align its position, and the “girth” will not allow, as they say, to fly off the road.

It should be noted that earlier in Japan they announced the maximum speed of such a train at 603 km / h. But never a speed above 600 km / h was not used in a practical version. Now it is planned that at such speeds the updated Chinese Maglev will be able to carry passengers.

Given the fact that, from the point of view of passenger transportation, the project has been causing losses for several years, it is important to note the following: Chinese space industry is very interested in it. The fact is that there is a project according to which the acceleration system when using the effect of magnetic levitation could be used to launch a certain payload into space. In particular, the option is being considered with the launch of satellites into relatively "low" orbits.

Yes expensive. China has the most high-speed lines, but they do not cover the mileage that is available for simple trains. Take the same Peregrine Falcon ... optimally 200 km / h is not very bad, but ... for it you need high-speed roads, which are few. And reworking the entire infrastructure for high-speed trains is kapets how expensive.

[Zeev zeev]

Nevertheless, passengers carried supersonic planes for almost thirty years. And the main problem was the high cost of fuel, which can be changed at the current level of development.

Yeah, they threw it back: we walk in sandals, it itches with a bump, we wipe ourselves with the Pravda newspaper. This morning I stood in a traffic jam for two hours - the robbers were driving.

[RESEARCHER]

And I would for comments, from which for 100 versts envy envy, would ban mercilessly, as for a mat and even more.
And according to the material of the article, I have such an opinion. Until economists are removed from the economy, it will not become modern.

[AU Ivanov.]

Economists are different. There are theorists who try to turn the steering wheel or give us very smart predictions, usually with a HSE diploma. And there are practices that have created and rule entire business empires. Without specialized education, but well knowing where the money comes from and how to make a lot of it. So they must manage the economy

[RESEARCHER]

Do not say, economists should serve the creators and not be engaged in optimization. But only then everyone will try to think of himself as a creator and they all quarrel. Who will make the decisions? That's the question. Everywhere solid economists. In the RAS, in the government ... even in the church.
Who do we have most of the leaders. These are people who received a normal first education, but really did not work in their specialty. Then no second, but economic. And now the path to the career ladder is open to you

[mmaxx]

It’s better not to have them at all than like now. Let the salary, as they say in the USSR. You can’t trust them anymore.

[AU Ivanov.]

I will sooner trust my life to a simple surgeon who has performed hundreds of successful operations during his practice than to a brilliant theoretician with a degree who does not really know how to hold a scalpel in his hands. With the economy, the same thing.

And to remove, this is in the sense of a spy thriller.

Who and what stole from whom and how, there are many interesting things. They wrote that the millionaire blogger died. Some 18-year-old Nastya Tropitsel. Or maybe she and her kind are stealing our children by telling them tales about a beautiful life. And the children listen and dream to live and travel beautifully and at the same time not to work a damn thing. And then we are surprised that we have to raise the retirement age and still have a beggarly pension.

This is all fixed quite easily. It is enough for all social networks to remove the monetization of channels. As soon as bloggers stop earning money from subscribers, there will be a need to look for a normal job. At the same time, blogging will cease to be such an attractive niche for shkolota.

About "horse-drawn", I hope you wrote without thinking? Not to mention "Putinism" and "enemies" that you stuck here. . If we live in the age of nuclear energy, this does not mean that all cars need to be equipped with nuclear reactors. It is necessary to consider profitability under any power.

[dauria]

It is necessary to consider profitability under any power.

Not only count, but also manage this profitability. Taxes, customs barriers, (or rates, as in the USSR). Forcing cash flows to be redirected to the right niche in the country. So let me disagree with you. In the USSR there were children's railways, unprofitable. There was a metro in cities - everywhere unprofitable except for Moscow. Close? In our city, trams were removed for unprofitability. All moved to personal cars. And now traffic jams - it’s faster to reach on foot. Now what ? To rebuild the whole city with roads and parking lots for personal cars is very cost-effective ...
The Chinese made a road, albeit a unique and unnecessary one ... But they got a bunch of intelligent engineers "in the load." The profitability is different. Short-term and long-term.

[Vadim237]

It’s cheaper to create and launch a hypersonic passenger plane with a scramjet engine than to build roads for such trains across the country.

[demo]

In China, today is the largest number of bicycles in the world.
I remembered one moment.
Once the Chinese invited me to go with them "to nature."
On three minivans drove towards the Sino-Korean border.
It was necessary to go for two and a half hours.
And in some place there was a need to refuel.
The company came across a little smoker, so there was an opportunity to get poisoned.
Moved away from the gas station to the side and look at the field.
And I can’t understand what is happening there.
And there a man goes with a harrow to get a horse, and next to him the little man steps and throws something into the ground.
I ask a Chinese man who was poisoning with me - what is this?
He looked and said (since the company works with Russia, there are a lot of Russian speakers) - it’s he who plants some local culture.
I say - for myself?
He was surprised - why for himself, for sale.
We drove away from the gas station, and I looked around and saw hundreds of such Chinese in the field on horseback plowing and sowing land.
And then it dawned on me - this is the reason for the cheapness of Chinese products.
Costs - feed the horse, but yourself with a bite to eat.

Such a train is more a status and a lesser means of transportation.
High-speed trains require the construction of special railway tracks.
Fenced and inaccessible.
But these still need to be covered from precipitation (snow, showers).
And if something happens, such a projectile, if it flies off the road (there were precedents in China), is clearly a mixture of meat, bones and magnets with wires.
Such a road, in general, should move in an isolated requirement, in an airless space, preferably two hundred meters below ground level.
And at distances of five hundred to seven hundred kilometers.
And go where mountains, deserts, forests, i.e. where it’s difficult and impossible to build roads in the usual way, on the surface.

[Sahalinets]

On this occasion, you will have to upset. The USSR imported grain not for the population, but for livestock feed. And mainly for feeding cows. Now we have a failure in beef, we import, but there are a lot of birds. And the feed costs there are completely different. To get a kilogram of beef requires 7 kilos of grain, and only 1,5 kilograms of chicken. This is how we got the "extra" grain ...

[Avior]

Grain is strife
Wheat was imported for the population.
Corn and carded food.

[AU Ivanov.]

Wheat was imported into the USSR, just to feed the population. "Ear of America"

[Okolotochny]

To get a kilogram of beef requires 7 kilos of grain, and only 1,5 kilograms of chicken. This is how we got the "extra" grain ...

No need to pull out of the general sense. The production of pork in the Russian Federation is the same as in .... the USSR !!! Did you catch the difference? Now calculate the cost of feed and for the production of pork. In beef, the peak of its production occurred in 88-89 years, somewhere under 4 million tons. Why do you know? In pursuit of reporting figures and a plan, because of feed shortages, she went MASS slaughter !!! And yet, in the USSR there was completely no branch of production of purely meat cattle, only meat and dairy. It is for information only. Not everything was smooth then. And do not mindlessly groan the current time.

[Piramidon]

Quote: Sahalinets

The USSR did not import grain for the population, but for livestock feed.

In the USSR, it was strained with durum wheat, which went to "feed" the population. It was imported. And its own (soft varieties) went to feed in animal husbandry.

[Vadim237]

47 million tons purchased by 1986 are somehow awesome for cows. Moreover, cows don’t eat one grain and bought 3,4 classes of grain because it was cheaper and they also bought under 500 thousand tons of meat. And we must admit the USSR lost a lot of its grain during transportation. Russia has as much meat production as the RSFSR in 1990 — more than 10 million tons, grain 120 million tons — and this with reduced sown areas of 377000 square kilometers 1177000 against the current 800000.

[Viktor Sergeev]

They built one miracle and realized that the fare is much higher than a conventional train, since creating an ultra-powerful magnetic field is much more expensive than wheels. But China can afford to get involved.

[Titsen]

The Chinese are just great!

[Viktor Sergeev]

In what? The fact that they built a non-viable vehicle? Plane is faster and cheaper.

[Thrifty]

The author, with the help of what exactly do you want to get magnetic levitation for an apparatus that can go beyond the Earth’s atmosphere with the same levitation? Of course, magnetic fields are good, but how exactly using only one field you can break away from the surface of the planet, and even go beyond the atmosphere? This topic has been procrastinated for decades! Humanity does not yet have the necessary technology to use subtle magnetic disturbances in the planet’s atmosphere to obtain power sufficient to accelerate to 7,8 km / s. , and exit into orbit!

[minus]

Apparently acceleration along the guides. In fact, a Gaussian gun. And compared with Railgun there is no wear of conductive rails.

[Motorist]

Quote: Minus

Apparently acceleration along the guides

I would do something combined: the start of acceleration on "electric", somewhere in the "end of the beginning" - connecting the taxiway. It's easier to carry a smaller mass of fuel ...

[knn54]

Not just to withdraw, but also to stabilize. Or magnets should be very complex in construction.
The train has a different principle.
Permanent magnets will not pull, and electromagnets need super powerful power sources. And "provide" superconductivity.

[Zeev zeev]

All problems with electricity and stabilization are completely solvable.

[Viktor Sergeev]

But the problems with the huge cost of creating a powerful magnetic field are the same solved? How much is the gap and how does its size depend on the power of the magnetic field? China has money to splurge, but economically this is a dead end.

[akropin]

But can’t it be used as an overclocking unit?

[Coward]

Before the green or No. 2 metro line reached Pudong, the project may also have been breaking even. But after they began to ride it only for the sake of curiosity. The main passenger traffic was transferred by metro.

[Kelwin]

So this is a cool toy, but this is what will happen in the event of an accident at the power supply section, if the electricity runs out ... this beautiful 600 km train will simply flop on its belly, or it has "emergency wheels" there))

This is a dead end tool, experimental, no one does this anymore, because it is unprofitable. Expensive, high cost of operation.

[rocket757]

The topic really appeared a long time ago, but no one could allow such an excess ... let's see how it goes for them.

and now all of Germany is on bicycles (although some are priced at the price of a car). In Germany and in France they didn’t go on the road to the Maglevs, it will be unprofitable, given the biting prices for tickets for ordinary wheeled high-speed trains (ICE and TGV), then no one will go to ManLevy

[kpd]

The Shanghai Muggle was commissioned by the Shanghai authorities by the German consortium Transrapid, which included Siemens (Transrapid 08 trains) and ThyssenKrupp (road) in 2001-2003. And in Germany itself, after an accident on a demo squad, the Muggle has not yet developed.

[Klingon]

I am aware that Maglev is not developing in Germany, what do you think the Germans will agree to pay 300-500 € per train ticket no matter how fast it is? Now more and more active people in Germany are changing to FlixBus (intercity buses) shopping mall. For example, a price from Basel to Frankfurt am Main on ICE costs about 75 € with FlixBus only 10 € and then 75 € is by the way still a very good reasonable price. and since electricity prices are creeping up, DB (Deutsche Bahn) will certainly increase ticket prices. And Maglev, in comparison with the conventional train of electricity, probably eats orders of magnitude more

[kpd]

Trains of this type have one chronic sore - they really do not like icing of the track, it can work in a warm climate, but in Germany or Russia in winter there are big problems.

[Viktor Sergeev]

They have a different sore: the greater the distance between the hull and the tracks, the more the magnetic field is needed, as a result, a trip on such a miracle will be more expensive than on an airplane.

[Old26]

Quote: SS-18

the future has come. Isaac Asimov could not have imagined such a design ..

Yes that's for sure.
In the early 80s, I was on a business trip in Moscow. Returned by train Moscow - Rostov-on-Don. Travel time is approximately 20 hours. Anyone who traveled by train on a business trip during the Soviet era knows that the main thing is to kill time. There were no tablets or e-books. All that remained was to buy newspapers and magazines (sometimes a whole bundle). Once, on such a business trip, before leaving the train, I bought at the station a book (series "Science", paperback) entitled "Urban Transport of the Future". If you flip through it now, you can say that 95-98 percent of what is written there exists. And some of the existing ones were not described there. So yes, the future has come and now it is even more difficult than 40 years ago to "fantasize" how the same transport will develop

[Viktor Sergeev]

That miracle rides is garbage. Can you lay out how much it costs to drive one kilometer? How much fuel is spent to maintain a powerful magnetic field? And then compare with the cost of flying on an airplane.

[Old partisan]

I am very happy for Russian Railways.
Nothing else a little bit and we will get out of the vaults of the Steam Engine and rush into a breakthrough into a brighter future !!!!
Hooray.

[Vadim237]

I am also glad - 70% of the entire composition of Russian Railways have already been updated, and you keep your own locomotives of delirium.

[Viktor Sergeev]

Steam locomotors are there. What does not suit you Russian Railways? Electromagnetic trains are nonsense, and very expensive nonsense. The wheels are much more economical, and the plane is the same. Only the Chinese were able to build this under-transport, and then one small route, that's all, physics and economics can not be fooled.

Of course, everything is learned in comparison, but it is still not worth focusing solely on money. Yes, travel on this train is probably more expensive now. It may be expensive for a long time, but ... Agree, if your main factor is the time factor (well, plus convenience), you will choose the best option. It may be more expensive, but convenient for you. Sometimes it is more profitable to pay "more" and move "faster" than "cheaper", but at the same time "longer".
After all, people flew on the Concorde across the ocean, spending more money, but at the same time three times less time. And so everywhere.
Here is an example. Summer 2010 Business trip to Moscow. I need to get to Vnukovo Airport from the center of Moscow. Two options
1. By metro to "South-West" and from there by minibus to Vnukovo
2. By metro to Kievsky station and from there by express train to Vnukovo
The price of the Aeroexpress is about three times more than the minibus. But outside the window is Saturday morning. According to information on the road, giant traffic jams. It may turn out that on the minibus I do not have time for the plane, getting stuck in traffic. What is selected? Yes, everything is correct, more expensive, but at the same time a high-speed route (in time). And so always and everywhere. Maybe at first this train will be expensive and unprofitable, but several years will pass and everything may change

[Viktor Sergeev]

Nobody needs a train that is much more expensive than a train and an airplane. Do you want speed: airplane, you want savings: train. Transport with 600 km \ h requires huge energy costs, smooth roads, very expensive service. Concord actually covered because of the high cost, and not accident, which was meager.
Do you need to get to the plane? And can you imagine how much the path will cost for such an electric car and how smooth it should be? This is all a toy.

[Klingon]

when the TOKOMAKI (ITER and others like them) work for us, then it will be possible to massively introduce Maga-Leva into the transport infrastructure, but for now it’s economically unprofitable fantasies apart from short trips from the terminals to the gate at some big cities

[mmaxx]

Still, I think that so far this is a technology demonstrator. The efficiency of a magnetic suspension is not a fountain, yes, and overcoming resistance is not a free thing.
But in the development of high-speed trains, China is cool. A very convenient thing. And better than the French for sure. Ours is not that either.

Such a project requires huge costs, no one thinks that it will be cheap. The costs are enormous, especially at the initial stage, but if you do nothing, such projects will not be cheaper or even implemented. Progress is underway, because electric cars 40 years ago did not have the same characteristics as they do now.
But if you need to get, for example, to the airport, which is at a distance of, for example, 50 km from the city border. Plus 20 kilometers from the airport in the city to the outskirts of the city. In total, let it be 70 km. At a speed of 600 km / h it will take you 7 minutes. At a lower speed at the same range - a little more.
In some situations, such transport will be necessary over time, in some - unnecessary. Let's say the same shuttles that go in such cases (buses). How much they transport people and how much they move. Of course, everything needs to be considered, but so to say right away that all this is nonsense and nobody needs it - too simple and presumptuous.
For example, railways to the south, for example, from Rostov to Vladikavkaz, can be made and the road will take, for example, an hour or a half instead of 10-12 by bus or 1,5-2 hours by plane. A regular train will also go 12-14 hours. So to do sooner or later have to. But of course you need to count
