J-21/J-31 Chinese 5th Generation Stealth Fighter

That's a logical fallacy. Oil is fungible. Engines are not.

On the flip side, Armand is missing the point of Chinese agreements with foreign engine manufacturers. China has capital and has a development plan - so every little bit of foreign technology helps. You can bet that for everything the Chinese are getting through reverse engineering, China is getting twice or three times as much via cyber, indigenous R&D, and other sources. Internal estimates put Chinese engine mfg capability at Western levels in a decade, if not earlier.

Does He have any logic? you are so stupid to try to convince him.

China is the 5th largest oil producer in the world, but we still import oils.

What does that have to do with the price of tea in China?

btw, oil production has fallen 10% from two years ago.

China has become so dependent on copying others you don't have the skills to create for yourself. You have failed to duplicate SCB production technology as well as many other processes. The result is delayed projects or substandard weapon systems that will never match the original. All this while the West and even Russia continues to surpass you. No one ever expected China to be begging Russia for new fighters at this late date. So much for reverse engineering and espionage.

Why is that that J-31 was declared export only shortly after a few flights?

Why is that that J-31 was declared export only shortly after a few flights?

Because this designed was rejected by the PLA and they need to find customers to finance it.

a pic taken last winter but released recently...
it also tells how those Military Enthusiasts who care about the defence equipment developments take so many great non-official images...and this explains why we could share and enjoy these wonderful jobs on the internet...

Passion is Priceless....

CAD images suggest 'strike' version of Shenyang J-31

Key Points
CAD images that have appeared on Chinese websites suggest a strike version of Shenyang's J-31 stealth fighter
The CAD images cannot be verified but would make sense given the PLAAF's lack of interest in the existing J-31 programme
Computer-aided design (CAD) images that have appeared on the Chinese internet indicate that the Shenyang Aircraft Corporation (SAC) may be considering a larger "strike" version of its J-31 fighter.

It is not possible to confirm whether these CAD images are from a corporate source, such as SAC's 601 Design Institute, or perhaps the work of a student from the associated Shenyang University of Aeronautics and Astronautics, which was involved in designing a flying scale model of the J-31 first seen in 2010.

However, it is plausible that SAC would be working on additional variants of the J-31, which is an industry rather than military-funded programme. The lack of People's Liberation Army Air Force (PLAAF) support for the existing J-31 may have prompted SAC to develop a new version that may prove more attractive.

The lengthened J-31 concept is reminiscent of the US Air Force's interest in a stealth fighter-bomber version of the Lockheed Martin F-22, sometimes called the FB-22, which was abandoned in favour of a new long-range bomber.

The CAD images show a triplane-configured fighter with front canards and rear horizontal stabilisers. The chined nose and the vertical stabilisers are similar to the J-31 fighter that first flew on 31 October 2012. The design also features clear planform co-ordination among the lifting surfaces to aid low observability.

The wing is much larger than the J-31 and increases fuel capacity for a greater strike radius, but the fuselage does not appear to be much wider. An internal weapon bay is not pictured but one image shows it armed with a single YJ-12 supersonic anti-ship missile on the centreline.

A chart that also appeared online shows the new design in comparison to the SAC J-15 carrier fighter, suggesting a possible future role on China's current and future aircraft carriers.

The chart shows that in terms of length, height, and wingspan, the new design is only slightly larger than the J-15, and as such may be compatible with Liaoning, China's Kuznetsov-class aircraft carrier, and a second indigenously designed carrier expected to be similar in size and configuration.

This lengthened and heavier version of the J-31 would require a more powerful engine than the Klimov RD-93 fitted to the J-31 to be employed from a short take-off but arrested recovery carrier such as Liaoning.

Russia's Klimov bureau has developed the 20,000 lb-thrust RD-33MK, while unconfirmed Chinese sources indicate that a slightly more powerful version of the WS-13 turbofan is also under development. The WS-13 has been WS-13 testing on a Chengdu FC-1 fighter since about 2010.

Any New prototype of J31 yet cause this new is quite old.

China to complete J-10 development before launching fifth-generation fighter - 11/17/2009 - Flight Global

China's main priority is to work on and unveil an upgraded version of its Chengdu Aircraft J-10 fighter, with the development of a fifth-generation fighter likely to wait until that is almost completed.

"Research and development is under way to improve the J-10 to develop a more powerful variant," says Wang Yawei, president of AVIC Defence, the military arm of state-owned aircraft manufacturer China Aviation Industry (AVIC). "This will take a bit of time and we are confident we will have a very good fourth-generation fighter when this is completed.

"We will gain a lot of knowledge and information from this development. By focusing on the fourth-generation fighter, we will be able to shorten the time needed to develop a new generation of fighters. After that, we will be able to undertake the development and production of a fifth-generation fighter."

a video of SAC's new bird's test flight this Apr...and with this, we might be able to answer the following question.

Did china recieved RD-93 for any other aircraft project than FC-1 ?

--------------
RD33/93's rich fueling design is the reason why the exhaust is smokey under some circumstances...

[video=youtube_share;C8SSQcYcxgw]http://youtu.be/C8SSQcYcxgw[/video]

BTW, As I known, another prototype of UAV project(Sharp Sword) might be using the RD33/93 as well. and the replacement and basicly a copy--the WS13 medium thrust engine is scheduled to pass the national test this year. most of test items have been done successfully...

Wow, this is something else than your Tejas. Must be pretty depressing for those Tejas designers to look at these videos.

China is running two stealth programs, one of them with target the export market. Both designs are expected to be completed by 2018.

Can't wait to see it fly in PAF colors.

I think both will be inducted in PLAAF.

Yes, very depressing, two designers took voluntary retirement and third attempted suicide.

Sir,

You forget our designers will work on this

or should i say improved version of this.


Pretty depressing for Finland when these will fly by your border.

 

[jouni]

Yes, very depressing, two designers took voluntary retirement and third attempted suicide.

But it is not their fault, isn't the design originally by Dassault and based on old Mirage. Their hands were tied. Sorry to hear anyway. At least they were dedicated to their work.
