China is developing a four-screw convertoplane

The Hong Kong newspaper South China Morning Post reported that China is developing a four-screw convertoplane under the designation "Blue Whale", mil.news.sina.com.cn writes today.

As expected, the maximum speed of the convertible with four rotary four-bladed propellers will reach 700 km / h (the highest speed among aircraft of this class, by 40% faster than the American V-22 Osprey of Boeing). Cruising speed will be 538 km / h, load capacity 20 t, flight range 3100 km, ceiling 8615 m, which is also higher than the V-22.

Nevertheless, some experts doubt China’s ability to create a fully functioning prototype convertiplane during the planned five-year period. It is expected that the "Blue Whale" will be mainly used for military purposes.

China is mainly tyrit technology. But they can embody. The name of the tiltrotor killed ... They will sell to Geyropa, but not buy, they will say that they do not respect the rights of homosexual whales. And blue geyropets will have to drive on blue whales.
But seriously, it is alarming. Have they started to do something themselves, and not be based on other people's technologies and developments?

[klimpopov]

That's all brought to the point of absurdity. After all, the blue whale is a beautiful animal and its like that. And the blue sky is beautiful after all, but associated with fagots and for the rainbow I’m generally silent. And yes, not blue, but pedagogy as Nikita said ....

[Skiff]

Yes, it’s strange why the blue whale, and not the blue monkey, because the monkeys are such thieves that directly reflects the essence of the Chinese, but in fact it’s funny that in 5 years they will build something they never did.

Well, excuse our government! Immediately you have to choose, either the Olympics and the oligarchs - or "implementation". There is not enough money for everything at once, the USSR could afford both the Olympics and military developments, with the state plan and a planned economy. RF, a stub of a union, with a market economy and a corrupt vertical of power. So bear with it.
And the Chinese should be respected, if only because they steal technology for the good of their country, are not shy about their means - so they can afford not to be shy.

[Civil]

Well, where are the "specialists" who will tell us tales about the fact that China can never do it. As with a carrier-based fighter for example).

We would have to resume the WIG program. And China, if it does not match the control system for the V-22 Osprey, is unlikely to cope with the control technology of such an aircraft

The Chinese are copying US forces

[svp67]

It would be interesting to know from where the "legs" or "wings with screws" "grow" in this "Chinese" project

[ALEXXX1983]

Well, even we can exhibit layouts Not the fact - that they will get anything out of this (the alleged x-ki are already outstanding).

[xetai9977]

I'm not sure that IT will be put on stream. Obviously, they were stolen from the Osprey, but I can hardly imagine how it will fly horizontally with parallel wings. Obviously not a working layout.

[Asgard]

Well, firstly, four engines on rotary crossbars ??? this is an impractical design ....
secondly, there is such a thing as vibration, so this vibration from four engines when turning the power plants will have to go into resonance and destroy the structure, the screws are huge gyroscopes, the two can still be synchronized, although the resonance period is still there and the mother shakes don’t worry))) but three or more, no way .... with such a weight tiltrotor ....

so the project))))By the way, there are models (they are small in weight)), but they also do not live long.

[787nkx]

My relative, a specialist in vibroscopy, did not express such doubts. In his practice, more powerful units were synchronized and balanced.

[Asgard]

when turning a working engine ....
read carefully....
as an engineer I tell you)))
Four moves are put on civilian airliners and military bombers, but they are not forced to change the plane of rotation there)))
they work perfectly in one plane, though there are critical modes there ... when maneuvering ....

[Mature naturalist]

There is such a thing called "silent block". You will not believe how effectively it dampens vibrations.
So, any technical problems are solved by competent design solutions.
If so, I'm also an engineer.

[Asgard]

RE zone ns, resonance, zone with its own type of oscillation ... ... repeating
So, (I see the silent blocks for the first time)))) vibrations with different frequencies overlap each other, which often leads to an increase in the frequency and amplitude of vibrations and, as a result, to destruction of the structure .... (not immediately)))
Moreover, when applying the gyrostatic effect with the vector of its deviation (by changing the plane of rotation)) ,,, even when the plane goes into a sharp climb, it shakes (c-blocks do not help)))
critical flight modes are called .....
According to the tiltrotor BellX-22A. which is shown below, I can say that the worthless engineers designed it, well, I had to make sure from my own experience, with gaps in the structures (weak points) and threaten the bucks ... and abandon the project as unrealizable .....
although everything is calculated elementarily, still at the design stage ,,,,,
and Engineer, remembers silent blocks)))))))

[Mature naturalist]

we remember, we remember that soldiers were forbidden to walk in step on bridges (bike?), well, the "dancing bridge" too ...

[Taoist]

The task is certainly difficult but completely solvable ... especially since it has already been solved.
XC-142A, Bell X-22A experimental tiltrotor with not two, but already with four YT58-GE-8D engines with a total power of 1250 hp

How many Americans suffered while debugging their "Osprey". And they still have big complaints about their reliability. It will be easier for the Chinese to be wrong - they have a lot of people. Their "Kit" will fall. They will put another advertisement in the newspaper, like "Five more pilots are required for testing ..."

[Conepatus]

It doesn’t matter how much China will suffer with its convertiplane. It is important that during these torments, they will gain experience in the design and refinement of such products.
Yes, it’s expensive, but it’s a waste of money for development, it touches the future, and we have nothing to do with it.

[viruskvartirus]

What I doubt from the fact that I read about convertiplanes, I realized that their main problems are large mechanical loads on the nodes, vibration, synchronization of work. On 2 screws it is difficult, and on 4. So let them deal with the idea that a king-tank type is just as grandiose and stupid.

[787nkx]

Work with Chinese partners in other pieces of iron shows that they are not capable of such ambitious tasks.

[JonnyT]

Nice!

I like the idea, only how will they implement it?
Regarding vibrations - now on the market a lot of all kinds of sensors and control systems have taken a very long step forward. It is possible to prevent resonance by means of an intelligent tuning system for the entire machine ... the task is difficult but doable!

What about the Chinese? Well, they will do it, but what will we get down to, what will we buy from them?

[Consmo]

They let them start a toy store to do this miracle. The Chinese invented a method without runs, tests for blowing in pipes (for example, in Zhukovsky something is blowing in a pipe that only Amerov and I have). To amaze the world with their plastic crafts. For fools who think that engineering and dozens of institutes can be replaced with large the number of Chinese yesterday rice-growing.
Greetings.
The saying is "smart as a hundred Chinese"

[Marek Rozny]

The Chinese invented a compass, gunpowder, silk. Paper is also possible (although the most ancient paper artifacts were found in the Hun’s graves and there is evidence that the Turks in the famous Chuy valley used to make hemp paper before the Chinese - then it was not yet narcotic, the chuyka gained a narcotic effect due to crossbreeding with another type of hemp in the Soviet 30s) and possibly even printing (here the Koreans dispute the primacy of the Chinese; moreover, this event occurred 1500 years before the birth of Gutenberg).
European nations are very forgetful. Throughout history, it was Asia that generated inventions and was engaged in science. Germanic, Romance, Slavic peoples were on the sidelines of scientific and technological progress. The achievements of the Greeks were completely forgotten by European neighbors. The peoples of the East, on the contrary, actively exchanged scientific achievements. Five hundred years ago, the whole of Europe was only doing what was copying the treatises of Central Asian, Arab, Iranian scholars. The first universities (in the modern sense) appeared in Europe thanks to Muslims in Spain.
Only 500 years ago, Europe seized the baton from Asia, but by now Europe is running out of steam. Asia woke up after several centuries of hibernation. China, Japan, India, Taiwan, Singapore are pushing the West in this marathon. Yes, even in Kazakhstan there are more inventions per capita than in the United States (but with the commercialization of inventions, we still have a full train, but we are also learning this).
Any Asian perceives the West as an upstart "from rags to riches." Moreover, the Chinese.
From an Asian point of view, the military, economic, political triumph of the West in recent centuries is an unfortunate misunderstanding that ... has already passed.
And before you laugh at the Chinese, remember that already 2500 years ago, Chinese officials passed exams to occupy government posts. And what exams did the Slavs take then?

ZY Now I cannot call the Chinese, but I cannot call them "stupid rice peasants".

Only historians dispute this somewhat. If the Chinese are such geniuses, then why did their genius begin to appear again only in the second half of the 20 century?
And now, China has chosen technocratic development, according to the Western model, but with its own specifics. I also want to note that modern China is very different. It also has ultramodern production of electronics, aircraft, ships and collective farms in which 50000 people, and they have one tractor! It is not surprising for a country with a billion and a half countries, twenty percent of whose population do not have documents, they are not registered anywhere (the consequences of the fight against high birth rates).
And in India a similar situation. And there and there are several thousand millionaires, and millions of poor and hungry ...
As for the scientists of the East, it’s stupid to argue. Thanks to their work, we have a modern level of development of science and technology!

She appeared earlier. Just 500 years ago, the impoverished West seized the baton due to the fabulous profits that Western empires began to receive from the robbery of America and later Africa. The amount of money received cannot be calculated. West won the lottery. This money was used for the technical modernization of industry, the construction of cities, as well as the development of weapons. In a short period of time, the West not only caught up with Asia, but also overtook it. So much so that Asia was smashed to smithereens by Western soldiers and politicians - China, India, Central Asia, the Muslim world became colonies of European empires, which gave all their juices to the West. Any attempt to revive and restore independence was extinguished brutally. The West took gold, oil, cotton, food, precious stones and other resources. He pitted Asian peoples with each other when there was not enough human resources for direct participation. Only in the second half of the 20th century did the old world begin to crumble. And here I must say thanks to the USSR, which supported anti-colonial uprisings around the world, trying to win over the liberated countries of Asia, America and Africa. The winner in the Cold War was not the United States, but the countries of the East. Since the post-war years (more precisely, after the collapse of the world colonial system), India, Korea, Japan, China, the Muslim world began to revive. The fact that the Chinese are engaged in the development of a convertiplane in 2013 is the merit of Deng Xiaoping, who laid the foundations of modern China several decades ago. The Japanese began the technical modernization of their country in the Meiji era (even before the Russo-Japanese war). South Korea immediately after the end of the Korean War took a course towards building scientific potential, the main reforms were carried out in the 70s (and then the foundations of modern giants such as LG, SsangYoung, Daewoo, etc.) were laid.
Yes, in India and China there are a huge number of beggars. But take the source reference and look at how much the number of beggars in these countries has decreased over 30 years. The numbers will amaze you. And the residents of the Russian border will confirm to you that the neighboring Chinese villages across the river in front of our eyes have turned into ultramodern cities.

Pride or Asian delusions of grandeur - Asians do not care much for the everyday opinion of Europeans. Russians consider themselves more cultured and great in comparison with the Chukchi. Not a single Chinese or Indian considered and does not consider European culture and history to be particularly significant.
Not a single European, even if he is born in Japan and speaks only Japanese, will never be his own in the eyes of the Japanese. Indeed, from the point of view of the Japanese, the European is a savage who can never reach the spiritual and cultural level of the Japanese.
In this respect, only the steppe Turkic-Mongol peoples and Koreans somehow more simply treat the topic of "great, small peoples".

Returning to the topic, only a few years ago, the entire planet maliciously believed that the Chinese would not be in space for a long time. And now they have already developed a program for the colonization of the moon.

The Greeks did the same 2500 years ago the Olympic Games, so what? The Slavs and Germans (their ancestors) climbed trees, were engaged in beekeeping at that time. And what does this mean: What plastic model will be in the future commercial or military transport? You can draw anything, but we do not kick ourselves in the chest "we created".
The mace did not fly again, what does this mean? Need to work and lick the design.
And the Chinese for the working issue even not yet drawings.
Reminded.
Recently there was a World Aquatics Championship.
The Chinese women rode and shouted that they would tear our girls in synchronized swimming.
It turns out that the tear has not yet grown. It is necessary not only to scream, but also to plow for 8-9 hours in the water. And not just sit in the water but also think.

[Conepatus]

1-History of the Slavs, more ancient than the Greek. Figuratively speaking, when the Greeks climbed trees, the Slavs already drank mead in the inn.
2-Chinese do not hold the stubbornness. What they can do themselves, they will do. What they can not do, they steal, or they will invite specialists and they will do it.
3-At the expense of water. China CAM is building itself a UDC, and not buying in France, China is building destroyers (an analogue of IJIS) and in Russia they are not even designed yet.
So, if they need such a convertiplane, then they will bring it to mind, sooner or later, but they will bring it.

everything you wrote is easily refuted. For the manufacture of gunpowder, saltpeter is needed, in China it was not in antiquity, it was transported from the Middle East and India. In Europe, monk Bertold Schwartz came up with gunpowder, all the raw materials for gunpowder were available and there are documents confirming this.
Compasses were buoyed by ancient Pomors and other sea peoples, and where the Chinese sailed there is no exact data, as well as any artifacts. Coastal navigation along the coast of the compass does not require
What else has Asia invented forever but the Japanese first saw firearms in the hands of Europeans.
About universities, complete nonsense, read about Greece and Rome
The Chinese education system was designed for 25 years and consisted in memorizing the works of ancient philosophers and was completely ossified. Mao was just educated in such a system and himself recognized that it was the outdated education system that prevented China from developing as a state.
And you write about the Slavs, forgetting that the Russians founded a gigantic state that exists to this day and we helped the Kazakhs and many others get out of the yurt and embark on the path of progress and development. The Russians pulled you out of the mud and not some mythical Asians ....
