Browser in China: AL-31F engines do not provide increased combat radius J-20

In the Chinese thematic media, the theme is that the J-20 fighters lack truly powerful Chinese-made engines. Once again, it is noted that Chinese aircraft manufacturers have reached "heights" in the use of "stealth technologies", the creation of an airframe using modern composite materials, but there is still a problem with engines.

Chinese columnist Hu Mikai writes that the J-20 fighters were "diagnosed with heart failure." With this term, the Chinese author denotes problems with aircraft engines, which are characteristic of both the J-20 and the J-31 under development.

From the material of Hu Mikaya:

Now J-20s are equipped with Russian AL-31F engines or Chinese WS-10 engines. But their performance is still low for the tasks that are set before the fifth generation fighters. Russian engines of this model do not provide an increase in the combat radius of the J-20. According to the plans, the combat radius is over 2 thousand km, but in fact it does not exceed 1,5 thousand km.

Is it connected with Russian engines?

According to a Chinese observer, "the WS-15 engine is a big hope for Chinese aircraft manufacturers."

Target values ​​of thrust for this engine are not less than 18 tons. At the moment, it is said that it was possible to bring the thrust indicator of Chinese aircraft engines to 16 tons, but after that the developments "stalled". An increase in engine thrust leads to an abrupt increase in fuel consumption, which, of course, negatively affects the radius of combat use of a new generation of Chinese aircraft. As a result, instead of 2000 km, values ​​appear that are a quarter less than the declared indicators.

Hu Mikai hopes that when the WS-15 engines are refined, "the combat effectiveness of Chinese fighters will be revolutionized."

And what is there to drive? Did they design the airplane for a reason? We use other engines for the aircraft of the 5th generation, and we designed them for a specific engine. Our AL-31F, for what was designed and gives out, no more, no less. The way out, either the engine is different, or the design of the aircraft is to be improved, to lighten, but then you have to throw everything out of it ..., in general, there is always a choice.

[hydrox]

Chinese comrades should be advised:
If you don’t know how to build engines for airplanes - go to drones or MLRS ... there you don’t need such power and thrust.

[Bad_gr]

Now J-20s are equipped with Russian AL-31F engines or Chinese WS-10 engines. But their performance is still low for the tasks that are set before the fifth generation fighters.

It is not a low-performance engine, but an aircraft too large for these engines. Among the aircraft claiming the fifth generation, the J-20 is the largest.

[Herman 4223]

After that, they will say that their plane is less visible on radars than ours? The greatest exposure is given by the glider, and the larger it is, the greater the exposure.

Does China hope to get product 30? Is this a hint from Chinese journalists? Product 30 will be ready in only two years.

In the summer of 2022, the military will begin testing an improved version of the fifth-generation fighter of the fifth generation Su-57, which received the official name "Su-57 of the second stage" and the unofficial nickname "Super-Dry."

Among the changes in the next version of the Su-57, one should expect a new engine and a package of modern avionics and airborne systems. The aircraft itself will become more maneuverable, tenacious and inconspicuous.

Megapolis development work on the creation of the Su-57 of the second stage includes equipping the fighter with a high-power engine, which is now known as “Product 30”. The new engine will allow the aircraft to accelerate to supersonic speeds without afterburner. The engine will receive a modified nozzle shape, which will reduce the visibility of the radar apparatus. Also, electric motors will contribute to this, which will replace the hydraulic drives of the control surfaces.

Pilots will be provided with new screens and a wide-angle collimator sight. In addition, the aircraft will expand its arsenal. The transition to the production of new aircraft will begin only after 2024.

They wanted, at least, to buy AL-41s from the Su-35th, they were told only with the plane. So they wander, it’s not so and it’s not that.

[Tcheluskin]

Why can't they buy AL-31F-M1, or we don't sell them? The thrust is ~ 1 tf higher, that is, plus 2 tf per aircraft.

[Cyril G ...]

There was a big contract for the supply of Al-31 engines to China, I don't remember the details. equipped with them mainly Jian-10

emnip, they got the M1. The plug is in their shoulder blades, they cannot copy it in any way ... This is called - there is no academic school. American professors in China joke - "you can bring a few thousand more professors here - there will be sense only in three or four generations"

The point is in school, in continuity. And if they, using our collapse and their spies around the world, sprinted in aircraft construction, then the story with engines is somewhat different, too versatile competencies are concentrated in them. We have also lost specialists and we cannot launch the Il-114.

Nature laws. And we still do not offer them a new engine model.

We'll have to suggest. "Product 30" for the Su-57 will go to the Chinese.

Russia is seriously tied to China with the export of raw materials. Europe is leaving

Well, let’s say that Gazprom will even more or less survive without Europe. But Europe without Gazprom gas - no. There is simply no supplier in the world who could replace Gazprom in the European market. Every year this dependence is growing.

But, just in case, put you a plus.

[voyaka uh]

The whole world is switching to liquefied natural gas.
It is still, on average, more expensive than a gas pipeline, but this is only
a matter of time. Terminals and storage facilities are being built throughout Europe.
And on the Atlantic coast of the United States too. Gas is distilled there from Texas.
For export to Europe.
So far, Qatar rules in Europe, but the Americans are already squeezing it out.
Turkey is trying to combat this expansion by creating a large hub,
but it is unlikely to beat the liquefied gas.

Gazprom supplies the EU twice as much gas as all LNG producers combined (including the Russian Federation).
As correctly noted, Qatar in the LNG market in the EU is more crowded than the Russian Federation, not the United States.
Plus, the Chinese market, which seems to have already raised duties on American gas, respectively, of the Russian Federation, and here it becomes a major player.

It is more expensive. He is more dangerous. Why don't Americans heat them at home?

You feel like a "good gas specialist", not a word on the essence of the problem, however, this is your style so apparently.

Well, yes you heard .... The dilemma of Ishak and the padishah ..

They are building terminals and storage facilities throughout Europe.

The economy is really nothing to do with ....

[Zaurbek]

Determines the entire distance from extraction / processing to the consumer. Up to several thousand kilometers a pipe is more profitable, more than liquefaction and a tanker. The main enemy of the Americans is Qatar, it is a competitor for liquefied gas. On the scale of the Russian Federation, where there is a lot of gas, but there is no access to the sea or to the ice-free sea .... but somewhere there is. The main thing is not to get hung up on the pipe. We wrote that we are starting to patent liquefaction and buy companies with patents and liquefaction technologies .... we were puzzled by tankers. This means that the main development will be in the area of ​​liquefaction.

Smishno ... we're like, with tears, will be forced to "give" the Chinese Su-57 so that they buy resources from us? Like Capitol Hill crying every new Penguin shipment?
Yes, and get acquainted with the share of SOEs in the Europa gas market in absolute and dynamic over the past 15 years ...

[voyaka uh]

"... we will be forced to" give "the Su-57 to the Chinese

----
Over the past decades, Russia has had two modern and complex
military developments that went into the troops: Su-35 and S-400.
And both of them were sold to China. Why ?: Your quote at the beginning of my post.
Now China needs a Su-57 with a new engine.

[5-9]

Far from being the most complex ... S-400 is just S-300 on a new element base, simply because Soviet S-300s simply cannot be produced ... S-300VM is no worse than, for example

[at84432384]

Gazprom has someone to sell gas to the Russian consumer. We have no end for our consumers, but how China will feel in six months or a year and whether it will have the resources to develop its aviation is a big question. The global economic crisis is just beginning.

I have suspicions that our engine is being abused! Maybe an American one with an F 35 or 22 was stolen. They are the Chinese, they need an eye and an eye behind them.

[Doccor18]

Hu Mikai hopes that when the WS-15 engines are refined, "the combat effectiveness of Chinese fighters will revolutionize

It is logical, and we hope that the AL41 will increase the capabilities of SU57.

[exo]

They won’t do it. Westerners, in the light of what is happening, don’t shine. And copy at a decent level, stolen, not enough technological groundwork.

[bar]

Our AL-31F cannot disperse the brainchild of Chinese aircraft manufacturers who have reached "heights" in the use of "stealth technologies", in the creation of a glider using modern composite materials? It's sad.
And these talented aircraft manufacturers under what engine did they sculpt their offspring? If it is for AL-31F, then apparently in their "stealth technologies" they miscalculated somewhere, since it does not fly. And if some other engine was meant, then what is our Russian to blame? Let them make their own, a flag in their hands and a drum around their neck.

[Russian2020]

Was there a stealth

[bar]

Was there a stealth

I would put the question more broadly - is there "stealth" in principle, or is it another "invisible dress" of the naked king? Until this is verified by a real war, it is difficult to answer this question. At least the F-117 shot down at one time in Yugoslavia is suggestive.

[Revolver]

Quote: bar

the F-117 shot down at one time in Yugoslavia is suggestive.

They shot down the S-125, but they aimed at the TVK, since it is technically impossible to achieve invisibility in the optical range so far.

[Bad_gr]

Quote: Nagan

in the optical range, it is still technically impossible to achieve invisibility.

".... The extraordinary began as soon as the engine started. This was expected: the rumor that it was necessary to wait for the start of the engine had already passed through the base, so the audience remembered all the details. It came, as expected, weakened by the distance" From the screw! " and "There is from the propeller!", then blue jets of the first exhausts burst out of the pipes on the sides of the hood, and immediately, simultaneously with the increase in speed, the plane began to disappear from view.

That it scatters, gains height, it was possible to determine already only by the movement of sound to the forest and above the forest. Following immediately both fighters rose: one began to catch up with the "invisible", and it was removed from the "twin". The survey was carried out from the ground, simultaneously from several points.

The pursuit did not work. The fighters have lost their "invisibility". And the audience lost it. That is, several times over the field, over the town, in a completely empty sky, the close sound of his engine slowly rolled, and the fighters rushed about in a completely different direction at that time ... "

Is it worth waiting for breakthrough achievements in this direction, is this a question?

[EnGenius]

I don’t understand these Chinese people. First, they write that the Al-31f is not enough to achieve the desired range, then they write that there is not enough thrust ... Did the Chinese gentlemen try to do tanks anymore? And if they also need more thrust for speed, then fuel tanks are all the more necessary! Or maybe their airframe weight is too large for these engines? Projected - now they are surprised ?!

[Zaurbek]

They are being sold Al41, what prevents them from delivering? For a transitional period.

With engines, such a trick does not pass from the word at all. You need to know HOW EXACTLY and WHAT the engine was made of. That is, you need to have a full description of the manufacturing process ... And that is not a fact.

[dauria]

That is, you need to have a full description of the manufacturing process ... And that is not a fact.

The British also thought so with "Nin" and "Derwent". Our copy was even better. Without a "complete description of the technical process". The general level is important - science, factories, engineers of all stripes ... and obstinacy. The Chinese have everything - they will do it. Actually, they fell in love with the American Pratt & Whitney F119 - 135. They've been poking around for a long time. Do the squeeze.
Something arrogant to their techies. Do not forget that their lunar rover on the moon ride?

So I don’t argue what the Al-41 analogue will do in terms of power, reliability and real resource. Someday ... In the far away light. Years of commercials in 10 if you're lucky.

Years of commercials in 10 if you're lucky.

A couple of years. Not more. And we will run to them for the engines. As we are now running after electronics. However, we are already buying electric motors and do not frown.

Why not buy Al41 now? It is serial .... we already sold it. For us, he will soon be the last generation. And you can put on J10.

[Cyril G ...]

Duc sold only motors with fighters. However, rumored to have sold a lot of motors. 24 Su-35 + 144 engines, rumored to be a fighter + 6 reserve engines. However, I repeat this rumor.

[Zaurbek]

Yes, I do not mind. Simply, if the problem is in the turbojet engine, then it is logical to install a more modern Russian turbojet engine. Maybe they can’t dock his UVT with J20 brains? So you can order without UVT.

Not. This is nothing more than a version ...... In the presentation of the division commander Zoltan Dani there the range of detection and taking escort beats more or less with theory. F-117 was detected by P-18, taken to escort CHP-125 and shot down by a two-rocket salvo.

The Ministry of Defense ordered the UEC - Ufa Engine-Building Production Association (UEC-UMPO) a universal engine that could be installed on Su fighters of generations 4+ and 4 ++. This was stated by the general director of "UEC-UMPO" Evgeny Semivelichenko.

“Every year the A. Lyulka experimental design bureau (a branch of UEC-UMPO. - RBK) receives 60–80 patents for something new. Moreover, today we are considering the possibility of creating a kind of universal engine using components of previous engines, ”he said.

Semivelichenko said that this universal engine can be installed on the Su-27, Su-30 and Su-35 fighters. “There is such an order from the Ministry of Defense, we are carrying out this work,” he said.
