Really? Chinese got first Su-35 in Sep 2017 and in Nov 2018, 13 months later, their J-10B already started to fly with WS-10 TVC in air show. Wow, Chinese scientists are not that good.


There is some techs in Su-35 that Chinese wants, but not TVC.






Russians will cut their key chemical ingredients supply and stop the maintenance service for the whole production line. The Indian factory will stop working within couple of months. This is how big guys control their foreign partners.
Exactly that is why I say Russia has supported chinese engine development otherwise all Chinese su30 copies will be grounded if Russian wanted.

No jf17 could be exported without Russian agreement either. And china still depends on Russian to keep j20 flying .

How did Russia supported Chinese engine development? Russia refused to set up overhaul factory of AL31 in China from the beginning.

Until today, all Russian scientists related to jet engine field are not allowed to come to China.

No, these engines in J20 are Chinese reverse-engineering copy of AL31 produced by Chinese factory, there is not a single screw or blade sourced from Russia. There is nothing Russians can do more than spitting.

And anyone who is saying problem is not conceptual, should understand, nothing is unsolvable. But, it depends, Anyhow, My team will start working on the requirements in the near future. We will directly explore electric.
Put this way, other kids started their education from the year one of primary school. India scientists decided they should start from the university since they already read the exam paper and answer of every grade.


Fuel engines will anyhow die by 2035.
Really? Wonder why Americans, Russians and Chinese are investing heavily on 6th generation fuel engine?

Hehe so delusional. All Chinese engine are build on Russian blueprint. If Chinese reverse engined Russian engine why would Russia sell china S400 and su35??

And without these weapons china is toast as it's its own planes are junk .

Please get some basic information right before opening your mouth. WS-10 is the result of reverse engineering of CFM56.

Because
1. Chinese has no intention to mass produce them. They already started to use the latest WS-10 to build new J-20.
2. There was an agreement, that any weapons sold to China by Russian company, Chinese can decode it but can't export the Chinese copy. Those Russian weapon acquired from other channels are not covered by this agreement.

And without these weapons china is toast as it's its own planes are junk .
Whatever you say.....

Please get some basic information, CFM56 is a commercial airline engine produced by Safran and GE. It won't fit in a fighter nor does it have afterburner. WS-10 is a clear copy of AL-31F, the same engine it is trying to replace but still fails to achieve the desired spool up time and engine life.

According to Russian state media there was no such agreement. The compromise was made that China would have to place orders large enough to make it worth Russia's time to turn a blind eye to IP theft. There are several examples of such missiles being offered for export. The engines are not offered for export because not even China is comfortable using them as they still import $1 billion worth of Russian turbofans per year.

The original design of the CFM-56 has its core directly transplanted from the GE F101 engine. One of the reasons why Henry Kissinger initially opposed the CFM venture with Snecma was their concern about the core design being adopted by the French. There were also security concerns regarding civilian exports of the finished product since there was possibility of reverse engineering for military use...which is exactly what China did.

The WS-10 itself is an evolution of the earlier WS-6 research project from which Shenyang had purchased 02 CFM-56 engines through Air China in 1982

If you followed aviation history you would know that the original CFM56 based on the F101 core was a commercial flop as it was not economical enough for airline use and had to be redesigned.

The WS-10 is a reverse engineered copy of the AL-31F. Reverse engineering a commercial airline engine that was redesigned to be more economical is not going to yield the high performance required of fighter jet engines

Ya right. J20 is already a junk with even al41 can't make supercruise. And now with smoking inefficient WS10 which it will be a flying casket.

So much for Chinese stealth . Lmao..

Wow amazing analysis, whoes this fella?
you knw him personely
seems like IItians are started coming to YouTube
Damn our Economy
You don't need to be an IITian to understand these things. Most people on this forum aren't from IITs, they have a strong grip on understanding of defence/aerospace/civil technology as well as economics, history and politics.

Hehehe true. IIT is a brand. Many people who are far more intelligent or talented are not in IITs either because they dont have the money or dont want to be part of the rat race !

IITs have become hauwa actually. Not that it isn't a good college but doesn't mean that there aren't any other good colleges with top quality education in India.

No, the core was the one they wanted to copy and there was only minor re-design in this part.
And it is exactly why Chinese targeted on CFM56 because IT IS A COMMERICAL product so they have a way to put their hand on it. And they did: in 1982, 2 CFM56 engines "Destroyed" in a fire.


The WS-10 is a reverse engineered copy of the AL-31F.
Please get some basic information, before open your mouth. The WS-10 project was approved in 1986. And national test agreement for AL-31 basic version wasn't even signed until late 1985. In other words, the whole development project of AL31 wasn't finished until 1987. How can Chinese make up a plan to reverse-engineering an unfinished product? The pre-condition of reverse-engineering is you need to have the original product in the first place. At the time, the whole Soviet got only around 30 AL-31. Was Chinese spy good enough to get one of them under the watch of KGB? I don't think so.

If you could have reverse engineered CFM56 into a fighter engine yet couldn't reverse it into a domestic airline engine tells the whole story.

WS-10 did not achieve its final configuration until it became WS-10A before 2002. Reverse engineering of AL-31F had started long before that.
