"The Russian engine does not have the required thrust": the US press on the new Chinese power plant for the Y-20 aircraft

The Chinese defense industry managed to create its own military transport aircraft in the person of the Y-20, but until recently it was equipped with D-30KP-2 engines, which are produced by the Russian company Saturn. This power plant did not allow the full potential of the new machine to be revealed.

This opinion is expressed by the American edition of The Drive. As noted, the Y-20, which entered service in 2016, is "broadly similar to the US Air Force C-17 Globemaster III." The carrying capacity of the Y-20 with the D-30KP-2 engines is 60 tons, the C-17 - 77,5 tons, the Il-76 - 43,5 tons [it is not clear where this figure is taken from: the IL-76 carries up to 60 tons].

As the publication explains, the PLA operates approximately 20 Il-76 units. However, many more machines of this type are required. At the same time, Beijing could no longer acquire them. [Apparently, this means the reluctance of the Il-76 operators to sell their aircraft, and the revival of their production began only in the 2010s, the first Il-76MD-90A took off only in 2015].

The Drive believes that under these conditions, China managed not only to create the Y-20, but also to equip it with new WS-20 turbofan engines of its own design. This, as noted, is evidenced by new photographs of the transport vehicle.

A remotorized Y-20 could close the gap with the U.S. Air Force in transport capabilities

- writes The Drive, indicating that before that, the deployment of limited production of a new power plant was expected only in 2024.

The WS-20 is expected to provide about 14 tons of thrust, compared to 12 tons for the D-30KP-2.

The original Y-20A is powered by four Russian low-speed D-30KP-2 engines, which do not have the required thrust and efficiency characteristic of modern high-speed turbojet engines.

- writes the US press.

Well, the usual, and obviously well-paid ifforvzroz, the tale that Russia only knows how to weave sandals, and the Chinese are obliged to crawl to the USA on their knees and beg to sell them their engines for transport aircraft. Such deceitful nonsense the Internet is piled high above the roof!

[Nazar]

Thrifty - what else to expect from the Amerovsky The Drive?
But the fact that China could no longer buy IL76, it is true - we produce them individually, serial production is not getting started in any way, we can say there is a queue behind them - and for the A100 it is needed just as a transporter to replace the depleted sides and in the Ministry of Emergency Situations. what kind of Chinese are there, they do not have enough for their needs.

Alas, in this case this dubious "victory" will go to our translator. For he is lazy (he translated the article for almost a year) and stupid, since he does not know the simplest terminology at all. It is not clear how (here How??!) could translate this:

russian low bypass Soloviev D-30KP-2 turbofans

... how "low speed"?
And the D-30KP, by modern standards, really has a low bypass ratio. It is a fact.

This can be put to the service of both traction (while maintaining flow) and economy (while maintaining traction). It is energetically more profitable to throw large amounts of air at low speed than vice versa. So, by increasing the flow through the second circuit, we can perfectly increase the thrust.

For the Nth time I repeat: Il-76 (without letters), indeed, once had a carrying capacity of 43 tons. But that was still with pterodactyls and dinosaurs. Now this modification has not been flying for 20 years. Or 30.

What's not clear here? The Il-76 lifts 60 tons only in the Il-76MD-90A version with the new PS-90A engines. And with the old D-30KP-2 engines, which are on most combat aircraft, it lifts about 4000 tons for a distance of over 48 km. The Chinese Y-20 engine, judging by its appearance, is an improved clone of the D-30KP-2 with increased thrust. Therefore, the publication compares the Il-76 with the old engines with the new Chinese aircraft.

edition and compares the Il-76 with old engines to the new Chinese aircraft.

The publication does not compare the IL-76. The article "Drive" deals only with engines and mentions C-17. IL-76 is not there. And 43 tons is the carrying capacity of a "clean" Il-76, that is, an airplane of the first half of the 1970s. All questions to the V-shny author, this is his gag.

[K-612-O]

From PS-90A, Ily are raised 70 tons, from D-30 to 60, at a distance of 2,5k, Il is simply lighter than the Chinese, and the combatants are gradually brought to the MDM version as part of repairs and put PSKs on them. And the D-30 was really outdated 20 years ago.

What's the news?
That the Russian engine is weak? So this is a no brainer, it's not for nothing that instead of him they adapted the new version of the ILA PS-90.
That the Chinese have made their own WS-20 is not news either.
Or that the author of this article caught the eye of The Drive and was able to translate what is written there?
Then congratulations. Although, the translation turned out to be so-so.

43. But this modification has not been flying for a long time. TD and MD are lifted by 48 tons.

[lopuhan2006]

For me, I no longer began to write a new article instead of the author. There are many modifications. The main thing is that PS-90 gives 16 tons, so the carrying capacity is immediately 60 tons. Only the Chinese are not yet pulling 60 tons, even with their own.

I only corrected that not 42, but 43 and that this modification can no longer be considered in our time, because it has not been flying for a long time. Only "MD" and "TD" and made on their basis, as well as a few MF and TD-90 / MD-90.

[lopuhan2006]

Thanks. We are waiting for the real indicators of the Chinese. I think they will spend a lot of time with the engine.

[Zaurbek]

The Y20 was originally designed for more powerful turbojet engines than the D-30. This is a temporary turbojet engine, the Chinese said so. All this way has passed the Russian Federation on the Il-76-476, from D-30 to PS-90-76. The difference is that the Chinese fuselage is designed in modern times according to modern standards and is more convenient for transporting equipment and drugs. And the Il76 was originally designed for the airborne forces, but now it has only been lengthened. As a result, MBT climb back to back in width. And there are a lot of equipment based on tank chassis.

If only the pictures were attached to the article. Yet the first Y-20B flew reliably.

It is interesting at what rate the Chinese will release them. If that serial Y-20 has already done much more than all the new Ilov-76 together with prototypes, and the Chinese took their wings a year later and for China this is a completely new machine, the manufacturer did not produce transport workers of this scale before.

[Vlad5307]

Some kind of stupid dispute turns out, i.e. about nothing. It is clear that the old engine is inferior to the new ones in terms of power and efficiency, but that is why there is technological development. But in any case, the carrying capacity for small, medium and long-distance transportation for the same aircraft will be different. If you compare, then it must be done correctly. There are many inconsistencies in the article and the author is clearly biased, which makes the article not analytical, but a camouflaged propaganda of the superiority of the West in this area. But our manufacturers quickly closed this gap, which makes our modern engines competitive with similar ones, and this is like a sickle in the West in one place. Hence all these supposedly analytical articles.

And how many of the available flying Il76 can carry 60 tons of cargo? 5-10 percent of the last released series? And let's not compare it not only with the C17, but even with the C2006 taken out of service in 141, which the Il76 did not reach in many respects. For example, flight range without refueling
