The J-20-engine discussion is over and other speculative topics ... to separate from the J-20-news !

[Asoka]

The document that we are looking at is 公司公告 or Corporate Announcement, which is a document every public listed company is obliged to publish whenever there is an event that will affect its financial standing.

This is a strict requirement imposed by almost every Stock Exchange around the World. The purpose being to inform investors and potential investors on activities that will affect their investment.

Thus this corporate announcement should not be taken as a affirmative document when we view it with regard to military development.

The number of forged alloy component sets is an estimation as clearly printed on this document thus is not confirmed as such, and what is not stated is whether these components are for test engines or serial production engines, or for engines of certain variants as in variant-A, or B, C D etc.

The person preparing this document is from corporate finance of a public company and not a military source, thus we should reserve some doubt on its accuracy with regard to military development.

This is totally B.S.

This is clearly an internal production projection document intended for internal circulation, only, that got accidentally released.

It is fine to release civilians engine production figures, but to release military engine figures, with very specific part names and dimensions, is clearly a very severe violation of security protocol.

Somebody will be severely punished for this lapse.

A competent Aviation Engineer with CAD/CAM tools could reproduce a whole engine, with those specific part names and dimensions and arrive at at fair estimates of its overall dimensions and power rating.

This is a leak of the most severe category.

Obviously you do not understand the meaning of 公司公告。 Just go to their official website, these 公司公告 is for public viewing. And have you invested in public listed shares? Go to any website of the stock exchange or share investment sections of a commercial bank or a stock broker, these type of public announcement is available for all to see.

The original report with the military engine figures was quickly deleted and replaced by a report with civilian engine figures only.

This indicates the original report was released accidentally.

But luckily for us and CIA/NSA/MI6, somebody has posted the original report on a Forum, before it got deleted. They should thank me, for this free intelligence scoop of the decade. I have always thought the secrecy concerning WS-15 is too excessive.

And if the report was intended for "stock exchange or share investment sections of a commercial bank or a stock broker", they are obliged to tell the truth.

It is not a license to lie, if the report was "public announcement " intended for the public consumption.

Somebody in China is going to have a very hot New Year.

yes, but does those reports mention anything about WS-10, WS-15 and other military engines, or they are just civilian engines?

This is the "internal document" you said, and I just downloaded it within minutes.

I try to upload here but the forum rule prohibited it because the file is too large (5.14MB), why not you just go to their website to find out instead of me posting some more disclosure.

It is a long PDF document, you may search its content, who knows may be they have deleted the sensitive part? I assumed you can read Chinese?

 

[Asoka]

I have told you that the original document containing the WS-10 and WS-15 has been deleted.
Show me, in your downloaded document, that still has the WS-15 figures.

You can search for the "XS-15" keyword.

You obviously haven't read the report you said you have downloaded, otherwise, you will notice it is a report on "河北钢研德凯科技有限公司, 铝镁钛轻质合金精铸件项目, 可行性研究报告"

中国联合工程有限公司 2 0 19 年 6 月

It is not about production forecast for the coming years.

It is an Engineering feasibility study on some light weight Aluminum-magnesium-titanium alloy forged components (铝镁钛轻质合金精铸件).

My friend, 公司公告 means Corporate Public Announcement as in 公司公共报告。Internal document would be 公司內部通告/某某部门通告。

After all these publicity on the internet for more like week now, the authority would have the sensitive military part deleted but not the document. Deleting a part of document does not mean the whole document is deleted.

Internal document very seldom go up to 267 pages (your post #617), it will be a extremely rare find. Most of the company internal document seldom have more than 5 pages, check your own company's internal document, i.e. if you are a working adult.

Sign off now for lunch.

You are a member of the Emergency Damage Control Team, from the PLA's Counter Intelligence, aren't you?

I don't envy your job, right now.

This is a major leak of first order magnitude.

Yes ... and in Your opinion it once again confirms that all J-20s are flying from day one with +210kN thrust pre-serial WS-15 engines.... we all know.

I must admit as @Figaro stated, seems as if it is some sort of 'deja vu' and we are again back on square one.

Yes, Truth don't go away. They like stick around "if it is some sort of 'deja vu' "
This, I don't agreed with you.

The new 3D TVC WS-15, with 3 layers of saw-tooth nozzle petals, is an industrial engineering marvel to behold.

No wonder that PLAAF is willing to wait for this new Marvel, keep the J-20 at low production, with the current WS-15 engine.

 

[Silicon0000]

5 could be MOQ (minimum order quantity) for one batch ........ May be

You are funny ... on the ne suds you claim the WS-15 is already operational from day one, in parallel you jump the waggon "is willing to wait for this new Marvel", while at the same time fully ignore thaf the currently produced J-20s are using a WS-10C....

Your whe theory simply does not fit!

The Chinese have a saying that says: "You can't wait up a person who is pretending to be sleeping."

I have already said a hundred times before that the WS-15 engine that J-20 have flown with, since day one, is an early version. They have changed the Engine around 2015, that is shorter and have an entirely different sound, which sounds like the howling of a dragon, as some Chinese said. This is the interim model in low serial production of 25 engines per year.

Now, a new version with 3 layers of nozzle petals is under development.

This is probably the mass production model that will produce 200 units per year, or 100 J-20 per years, beginning in the middle of 2020's.


They have at least 3 versions now, according to an earlier leak, which an award was given to a design who improved a third Patch of the Engines.

Now, the mystery of WS-10/12, with saw-tooth nozzles, on J-20 is solved. These two engines are for the navalized version of J-20 to be used on China's future Aircraft Carriers, with Electromagnetic Catapult.

These WS-10 engines will synchronize their power output with the EM Catapult, which could adjust the power output level, depending on the weight of the aircraft, to be launched. In this way, the maximum g-force load on the pilot and the aircraft is greatly reduced, and lessen the damages on the pilot's spine and delicate electronic equipment.

But there is no need to knock down those WS-10/12 engines with stealthy saw-tooth nozzle petals. We don't know the maximum thrust are. They could be a giant leap above the WS-10A.

You should really chance your medicine... WS-10C = WS-12 for a so far hnknown naval J-20 that has no catapult gear and no-one even mentioned.

You are a genius ...

And why do they change to the lower-powerful WS-10 if already the WS-15 is sooooo great?

But you genious will surely explain ...
