Interesting catch...........

Thrust Vector Engines for the J-10 and Carrier News
January 20th, 2008
Richard Fisher, Jr.
Russian sources stated that China and the Russian Salyut engine concern were in the process of negotiating a future sale of the AL-31FN engine, but with a axisymmetric thrust vectoring nozzle. These sources would not state the number of engines in this package, but did confirm previous statements that the thrust vectored engines were intended to support a Chinese Navy version of the Chengdu J-10 fighter (this came at a time where J-10B was in development and there was no news of J-10AH) --presumably for aircraft carrier use. In 2005 a Russian source had noted China’s interest in the thrust vectored modified version of the AL-31FN, but in 2007 it is now apparent that such a sale is under negotiation. With its forward stabilizer “canard” configuration, thrust vectoring for the J-10 could conceivably allow a lower landing speed, or enable a faster recovery take-off from a “Bolter,” or a failed arrested carrier deck landing. Both capabilities would be of interest to the PLA Navy to increase operational safety. In addition, other sources indicate the PLA will use the thrust-vectored J-10 version to better enable useful payloads to be lifted from the high-altitude bases of the Tibetan Plateau just north of India. Otherwise, thrust vectoring would add more to the already inherit high maneuverability of the J-10’s canard configuration. Russian sources claim that the thrust vectoring nozzle will not add additional weight to the engine, which might then require airframe or ballast modifications for aircraft.

No, It means, there is a very high probability that current AL-31FN engines imported reportedly for PAF have TVC technology embedded in them....I can still recall a news calling these new ones "Improved" AL-31FNs......

AL31FN TVC turbofan ( service for J10) are on display at the 14th Beijing Aviation Expo now.

but chinese WS10B have more thrust than AL31FN and WS10 series will also press ahead with the development of TVC version soon.They have begun to feel worried and Russians are impatient to sell china TVC version AL31FN now

I think the deal has been signed already, Huzuigang's interview also pointed towards these AL-31FNs being imported for Pakistani Platforms. Thats why I raised this point that even the current btach production of J-10Bs will likely have Al-31FNs before eventually switching to WS-10B...

You do know huzhigeng also said Pakistan is getting a modified A version right?

J-10B fighters are equipped with new radar for continuous shape test
Posted by Zhao Yan 6:33:00 PM, under J-10B fighter | No comments
Recently, J-10B fighters were equipped with China-made Taihang engine and took multiple stereotypes continuous flight on an airport in Chengdu, some aviation enthusiasts said the J- 10B fighters had high degree of difficulty of maneuvering flight, the aircraft's performance is rather excellent. Before this, the J-10B fighter jets have been using Russian-made AL-31FN engine, if the engine supply problems, these fighters are easily controlled by others, Taihang engine equipped with the new J-10B flight test aircraft will complete shape, will greatly enhance our military the level of equipment, get rid of the heavy reliance on foreign air force.
J-10B fighter improved aerodynamic structure, through the installation of a new type of airborne fire control radar, a new generation of avionics equipment, and optical radar system, the installation of new electronic warfare devices, and equipped with a domestic Taihang engine, greatly improving the operational performance, its overall combat capability than US-made F-16C / D fighter aircraft and legal Mirage -2000-5.

could it be semi-stealthpakistani verison FC-20 i think there avionics are quite matchable with erofighter and rafale but question is semi stealth and super cruise these 2 things well i was thinking that FC-20 could go with WS-15 which is on J-20 but not sure about this i saw in wikipedia that on WS-15 is for J-20 and J-10B but not sure which 1 is pakistan is getting

 

[cloneman]

FWS-15 is still in developing,we won't expect to see it in massive production until 2015.And there

is a long list which is waiting for the FWS-15 like the J-20,the SAC J-XX,after that we can talk

about to fit the FWS-15 on the J-11 and J-10 variants.A realistic solution is to install the

improved FWS-10 variants on the future J-10s,the Niming factory is massivelly producing the

FWS-10 and each block of the FWS-10 has a slightlly improvement on the thrust and life

span.The FWS-10 still has a lot of room to improve,a 145kgf thrust variant will be great helpful to

the J-10.

I personally think modified J10A version is PAF's own choice .bcz huzhigeng also said that PLAN's J10As and PAF's modified J10As will be the last batch of J10As, Then J10A's production line will be closed .PLAAF will receive the first batch of J10B by the end of this year.

Even the PAF pilot's (Sliapani...whatever..Do we have pilots named like this? lol) interview apparently gave an impression that he was testing J-10A. But there is some confusion in sources as well. While insiders like EagleHannan point to J-10B as PAF's primary requirement and presence of a test team at CFTE alongwith a Chinese one to evlaute J-10B as a reason for that. Huzhigeng point to the other side. I guess we'll know as the subsequent developments emerge to give a clear picture. But i would do like to ask a question. AL-31FN are not exclusively for PAF, Its is also reported that J-10B prototypes were tested with TVC AL-41 engines sold earlier to China by Russia. Since the current lot of AL-31FN is also TVC, there is a very high probability that these engines will land in both PLAAF and PAF's platforms. However, if PAF goes with J-10A with AL-31FN, then there must be a platform undergoing testing with a TVC engine as a design appraisal for TVC engine would be required for a platform which was orignally not ment to operate with TVC engine. Why AL-31FN would land in PLAAF platforms as well? because WS-10B testing will likely take a considerable time, point in case WS-13 on FC-1. Not to mention the subsequent developments to have a TVC nozzel. It seems logical that PLAAF will also move ahead with AL-31FN for the time being rather than wait for certification of WS-10B

China signs deal for 150 Russian fighter jet engines: Report
PTI Sep 22, 2011, 04.43pm IST
Russian fighter jet engines|jet engine-maker

BEIJING: Russia's top jet engine-maker has signed an agreement to supply over 100 high powered engines for China's new fleet of fighter jets, but Beijing is yet to ratify the deal as it is apparently miffed by some stiff conditionalties of the deal, a media report said.

"The contract will involve 140 to 150 engines, but it has not been confirmed by authorities in Beijing," Alexander A Drozhzhin, the head of press for SALUT, a top Russian company that manufactures engines for the Su-27 aircraft, regarded as the fourth generation fighter aircraft was quoted as saying by China's state-run Global Times.

According to US media reports, the Russian state arms exporter, Rosoboronexport (ROE), announced in July a sale of 123 SALUT-made AL-31FN turbofan engines to China for USD 500 million.

The engine is a variant of that used in the Su-27 and Su-30MKK/MK2 fighter jets and is designed to be used on China's single-engine J-10 fighter jet, Drozhzhin said.

The reported deal involves the third series of the AL-31FN, which have a maximum thrust of 12,500 kilogrammes and 2,000-hour service life.

The AL-31FNs currently used on China's J-10s have 11,700-kilogramme thrust and 1,500-hour service life, he said.

China's air force development made headlines earlier this year after news about the prototype J-20 stealth plane emerged. However, aircraft engine design and manufacture have been lagging behind, the newspaper said.

China, which has not got much of technological access to both US and EU aviation technology due to restrictions, is developing a range of new planes including the stealth version, but the engines for the most of these planes were still being imported from Russia and Ukraine, mostly case-by -case.

According to defence analysts, the Chinese, who are masters of reverse engineering technology, were bogged down with Russian and Ukraine insistence they should be used only planes and not for reproduction.

It is the same case with the JF-17, being jointly produced by China and Pakistan as the engines for it were being sourced from Russia.

Pakistan plans to get 250 JF-17 in the next few years. About 50 planes were produced last year and China has assured handing over another 50 this year.

Since 2009, China used Taihang engines, developed and produced by the Aviation Industry Corporation of China (AVIC), have been fitted to the double engine J-11 fighter jets, its J-15 carrier-based variant and an upgraded version of the J-10 single engine fighter.

Lin Zuoming, President AVIC said it had taken 20 years to develop the Taihang, a Chinese engine and that work on the engine was progressing very well.
