Re: China J-XX official graph

Its like the J-10 and the F-22 had a love child. But seriously I think its difficult to have some concrete shape of the secret J-xx...hence lots of artist impressions flying around.

Let's hope that the F10 and F1C are able to be produced successfully before putting bets on the JXX.

Re: China J-XX official graph

It looks like another F10 development

as the J-XX pics i've scene on the net seams to much more like the
F22

The chinese are making alot of concepts at the moment

theres even an off shoot of the fc1 that looks like an fc1 fuselage with a delta wing and canards

? Not fully operational????? And with only 200 engines on order, it hardly looks like it'll be the big deal it's often made out to be.

It has at least one full squadron in service opposite to India. As for engine, it has 154 AL-31FN ordered so far (54 in the first bunch and 100 in July) which is expected to all be delivered before the end of 2006. http://www.strategycenter.net/resear...pub_detail.asp

Depending on what kind of AL-31 variant Russia is willing to offer after this delivery, China may choose to order more or stick with WS-10A which actually has better thrust and T/W ratio than the current AL-31FN.

If you can read Chinese or feel like translating from traditional Chinese to english using babelfish, check this kanwa article http://www.kanwa.com/mrdt/showpl.php?id=207

In the bottom, it says China is dicussing with Salyut for a AL-31FMN variant which will hopefully have 15000 kg thrust. Note, AL-31FM has 13700 kg thrust.

J-10 will be the work horse in plaaf, there is no question about that. Especially since China has stopped building J-11A and stopped purchase su-30mkks.

Tphuang,
I think I read the Kanwa article in English already (brought a copy of the mag in HK). Kanwa too express the notion that the J-10 may be loosing ground to the J-17 as the future PLAAF workhorse. Kanwa estimate the J-17 to be about 30% cheaper. Also, they speculate, quite reasonably, that the use of the AL-31 engine on the J-10 is tied to purchases of Su-27/30 aircraft, making the idea that China will not buy/produce further Sukhois less than likely(?).

Chinese engines like WS-10 appear some way off.

Re: China J-XX official graph

Coming back to topic;

This is not J-XX. J-Xx doesnt have delta wings, doesnt have bottom wind inlet (its suppose to have two side wind inlets under the wings) & certainly no canards.

Here is a possible lay out from sinodefence : http://www.sinodefence.com/airforce/...x_gallery1.asp

& this is the origional rough model if J-XX presented during some show: http://www.sinodefence.com/airforce/...r/fighter3.jpg

Re: China J-XX official graph

none knows what j-xx looks like. the internet concepts thet have been put out are either mig-1.44 rip-offs, su-47 rip-offs, or f-22 rip-offs.

but back on topic...
the chinese evidently want to put the al-41 on the j-xx, along with some indegedous avionics and weaons suites. the radar is uncetain, either an isreali, russian, or indegedous. it better be good thoguh!!!!

Yeah thats what i forgot to mention....realy no one knows what J-XX look like. Even the model shown at the defence exhibition may be changed as the project goes under way. So if any of u ppl find any pic on J-XX (at this moment) they are just mere asumptions & children at play.

I thought China was testing TVC WS-10 for J-XX.

Radar is said to be AESA but the version is unkown. China is said to be developing its own AESA.

yeah, I read that article too, but that article was based on the premise that china might be purchasing 500 RD-93. It looks like JF-17 might not be available for another 3 years. By then, there will be 150 more J-10s (using the pace of 50 per year). I personally think the number 500 is quite alarming, since it means WS-13A will probably never be used on JF-17. Either way, considering China has promised to purchase 250 JF-17 and PAF committed to 150, 600 engines for that really is quite reasonable. Let's not forget JF-17 is suppose to be the plane that China is marketing to poor countries. As for WS-10, it is almost complete. The current estimation is that WS-10A will start production sometimes late this year or next year. There was a problem with it in 2004, but it has apparently being resolved. As for sukhoi, China will definitely buy more sukhoi, but higher quality sukhoi than the garbage it is getting right now.

As for J-XX, I remember JDW posting that J-XX is in wind tunnel testing stage in 2003. Now, if we use J-10's develop as a barometer. I'm guessing the first prototype will come out in 2008 and probably fly in 2009 and it will go through pre-production testing starting from 2012 and join service in 2015.

As for engine, China is going to most likely use AL-41 at least in the beginning, like it is using AL-31 on J-10 right now and then some indigenous engine later when it can match AL-41 in performance. I really don't think 2 WS-10A can produce enough thrust for J-XX to compete with the likes of PAK FA and F-22.

Oh man, I don't know if you all are old enough to remember the endless artist renditions of the F117 or the Soviet "Secret" projects that the pentagon would publish to get the pucker factor up and get more funding for the military.

When the day comes that any country puts an aircraft in the air that can rival the F22, than I willl start to believe the rumours and hyperbole surrounding the percieved chinese military secrets, brought to us all by the paranoid and reaching for straws press conferences of Donald "Where is the weapons of mass destruction" Rumsfeld and company.

it's posted on an official chinese newspaper that a new engine has finished 4 month of endurance testing. It didnd't mention WS-10A specifically, but clearly it is WS-10A due to the timeframe and the description of the engine. That's considered to be the final test before certificaiton, so production should begin sometime late this year.
