"One of the obstacles to stealth of the J-20 fighters are the Russian Al-31F engines" - Indian expert

Indian media publishes materials that examine the degree of threat from the Chinese fifth generation J-20 fighters. One of the Indian experts looking at this topic is Srinjoy Choudhury.

Traditionally for many Indian experts - without providing specific technical and technological justifications (and this is what Chinese experts are guilty of) - Chowdhury writes that the PLA J-20 fighters “do not have a high enough level of stealth to allow them to remain unnoticed by ground-based air defense radars. and aviation India. "

Indian expert:

It may not turn out to be at all the stealth in its level, which should be characterized by modern requirements. The J-20's stealth deficiencies will allow Indian air defense to catch their breath - it is quite easy to track Chinese aircraft in the air.

The Indian press indicates that the PLA Air Force J-20 fighters have already twice been detected by the radars of the Su-30MKI aircraft of the Indian Air Force.

Srinjoy Chowdhury:

One of the obstacles to the J-20's stealth is the Russian Al-31F engines.

It is added that during the afterburner the aircraft "consumes a huge amount of fuel, which reduces its range, while making it visible to radars."

As a result, the Indian observer sums up:

The J-20 is a challenge from the PLA for the Rafale fighters acquired by the Indian Air Force, but it has drawbacks that the Indian air defense system can exploit.

Leading engine builders, aircraft builders and air war tactics write.

Uh-huh, these are the Indian experts who armed the army with three rifle models, unfinished a flawed tank, abandoned work on the project of their own aircraft and rent our nuclear submarines, dirtyly allowing the Americans and not observing secrecy? Gygygygygiants of advanced technical thought are unthinkable.

calmly, there conditionally the true kshatriyas are engaged in war.
Merchants / Vaishnavas / only make deals. Satisfy the needs of high Kshatriyas. India uses a unique paradigm. India can buy weapons and technology from 2 centers at once. The Western world or Russia can provide TECHNOLOGY. This is such a complicated thing that you cannot explain. cupola...

[ZEMCH]

I agree! What is not Hindu is a stealth expert))) It's like British scientists = Indian experts

[Real Pilot]

Yes sir! Leading experts

The J-20 is a challenge from the PLA for Rafale fighters acquired by the Indian Air Force, but it has drawbacks that the Indian air defense system can exploit.

But for some reason, for Rafaley, but they were observed on the Su-30MKI radars But Rafali was not seen, they were standing somewhere in hangars ...

Well, the flaws will be exploited by the Russian-made air defense system

The article as a whole reads: do not buy Russian engines, they are bad but to myself: let the Russians sell us better

[Zaurbek]

The correct move ... Tejas with Al31 and, later, Al41

[iouris]

In search of the "ultimate weapon" ...

[Gubernia]

Let the Indians create at least something like that themselves and check it in battle, and then compare
Pancake experts found
P / S / Your op and dances on military airfields before flying out on a mission .. Everyone sees and even dances It's hard to negotiate with you Indians
Sooner or later, you will remember Russia and regret it

[Zaurbek]

At least they will unify the fleet, make competent purchases of equipment and get rid of the "Zoo" of aircraft.

Why would they? They had a clash with the Chinese in the summer at the border, wall to wall, with the use of crowbars, clubs, various stabbing and cutting weapons. Now they need to study the Medieval experience and fill up the forges with orders ... although here the Indians have an advantage can "mobilize" the War elephants!

It is useless, this is their mentality .. The brighter and brighter, even if expensive, the better ..
And they are fighting on old Soviet flashes and even shot down something ..)))))
They are not fixable .. Someday they will be ripped off in full, even from a small country in the neighborhood

[Zaurbek]

Oddly enough, the only correct contract is the assembly of the Su30MKI.

It was them .. So they got it with their Bluewood in arms)))) ..
How much can you explain to them the strategy of military affairs and the standard of weapons, regulations, etc.
And they all dance.))))

Let's laugh together .. Thank God there is no such thing in Russia ..

[Eragon]

A howitzer is nothing, dancing is everything.

in afterburner the aircraft "consumes a huge amount of fuel, which reduces its range, while making it visible to radars"

And the Indian "expert" will not tell you which aircraft engine does not consume more fuel on afterburner? It is clear that the long-standing territorial "friendship" with China requires at least injections, but why focus on Russian engines. And when will the Indians fly on their planes with their engines?

[Sandro1977]

So kickbacks for Rafaeli need to be worked out and justified somehow why the planes were not ordered in Russia

[mihail_mihail0620]

Quote: rotmistr60

And the Indian "expert" will not tell you whose and which aircraft engine does not consume more fuel on afterburner?

The Indians apparently assume that with the Al-31F, the J-20 cannot reach supersonic speed without afterburner, which makes it more noticeable.

[rocket757]

Purely professionally, I wonder what will develop faster and more efficiently ???
Stealth technology, camouflage or detection means, targeting those "invisible" ???

[Mountain shooter]

Oh, those Indian experts! Don't they like the engine? But where did the myth that the J 20 is a fifth generation fighter come from? IMHO, this is a hybrid. Elephant with a teapot. What kind of afterburner supersonic is there? There and afterburner not everything is clear ... So in this they are right. China is so ... mysterious.
And let the Indians make something for themselves. High tech. 5th generation engine type. The French have promised them something ... Wait.

[DAQ]

They were promised kickbacks!

Hmm! You might think that "Raphael" has no shortcomings ..... Although this is reasoning Indian an expert, which means -"an expert" (in quotes)!

Indian expert:

He may beI'm not that stealth at all

Key words "may", "be". Further, you can skip reading such experts.

[Pashhenko Nikolay]

Does the expert know that radars do not detect a heat trail?

The radars seem to detect fuel consumption.

the aircraft “consumes a huge amount of fuel, which reduces its range, while making it visible to radars»

Apparently on their radar screens readings of flow meters are highlighted.

[Alien From]

The most competent people say this is ridiculous.

[Vilensky]

One of the obstacles to stealth of the J-20 fighters is the Russian Al-31F engines "- Indian expert

.
Indian experts, like British scientists, who have established that there are about half of the men and half of the women on earth.

[svp67]

This is something new in the field of radar ... But damn Holmes, how ????? How does the engine and high fuel consumption make the aircraft better visible on the radar screen?

[Jacket in stock]

Quote: svp67

oh damn Holmes, how ?????

Which one to the top.
This expert does not care, the main thing is to say that Chinese is bad.
And to explain, and even plausible, it’s necessary to understand the topic at least a little.
But why, as they say, the stupid will not notice, the clever will remain silent.

[Astra55]

Yes, elementary, Watson!
You probably never paid attention to their "radar" being in India!

[Thrifty]

It would be better if this Indian danced silently than to carry such nonsense! !!

[TermNachTer]

It would be better to feed the elephant))))

[TermNachTer]

How is the exhaust of a jet engine visible on the radar screen?)))) An expert from a country that has not been able to finish something stuck between the 20rd and 3th generations for 4 years)))

[askort154]

Two tribes came from ancient India to the West: the Gypsies and the Jews. The Jews "dwelt", although they had "wandered in the wilderness" for a long time before. and their fellow Gypsies, still "wander" around the world.
And modern indigenous Indians, weeping, give their last rupees
to defend against China, regretting that then more Jews were expelled than Roma. Summary: today to have serious business relations with India, what to play preference with "scammer".
(I am never a nationalist, I am a realist )

[yehat2]

the fact that in terms of EPR efficiency, according to the Americans themselves, the f-35 is about 22-1.5 times worse than the f-2, just because it has 1, and not two, exactly the same engines. This is the logic. The more engines on the plane, the more invisible it is. And the J-20 has a problem with stealth because it had to be equipped with not 2, but 10 al-31F engines. Then not a single bastard would have detected it and the afterburner would not have to be turned on.

I would draw your attention to one point: merchants are Vaishyas, and Vaishnavas are Vishnu worshipers! That is, a Vaishnava can be a representative of any caste, but usually they are brahmanas - Vishnu worship has traditionally high standards.

Reduce the price of fighters!

This Miracle ... Ugh! You’ll break your tongue! Whether the name, or drove. Does he have something to offer the Chinese?
