Chinese Next Generation Fighter Jet: J-XX
There is no concrete names for PLAAF's next Gen Fighter.
It can be called J-12, J-13, J-14, but gernerally ppl refer it as J-XX.
5th Gen Fighter Requirements:
- Supersonic crusing (Supercruise)
- Thrust vectoring
- Super maneuverability
J-XX vs F/A-22.
J-XX Next-Generation Stealthy Fighter Aircraft
According to the reports of the Jane's Defence Weekly, China has already launched its next generation stealthy fighter aircraft programme, and Shenyang Aircraft Industry Co. (SAC) has been selected to head research and development of a new fighter for the PLA Air Force.
Development of the subsystems including the engine and weapon suite for the next generation fighter has been underway for some time, according to the report from Jane's. Images of the concepts show a twin-engine aircraft sharing some design traits with Lockheed Martin's stealthy F/A-22 "Raptor" multirole fighter such as the internal carriage of its weapons.
Meanwhile there isn't much public information about the programme. The aircraft, which could be designated as J-13 or J-14, is still going through initial concept work, the same stage as the USAF Advanced Tactical Fighter (ATF) programme in the early 1980s, which later led to the F/A-22 Raptor. Sources within China's confirmed that the SAC is looking at a twin-engine, single-seat, single vertical tale fin design, but other design proposals has yet been ruled out.
As China has developed close ties with Russia's aerospace industry and has license produced many planes of formal Soviet designs, it can be predicted that the J-XX would include some, if not many Russian technologies and designs. China has been offered a 'joint development and production' of a new fifth-generation fighter by Russia -LFI. Russia has been trying to sell this concept both to China and India for some time, but neither of them has committed fully yet. According to Russian resources, the LFI will be able to counter U.S. second fifth-generation Joint Strike Fighter (JSF).
Stealth and thrust vectoring are two must-have features in all aircraft being designed in the 21st century. If is not clear that how much progress Chinese designers have made in these areas, and Chinese aircraft industry may have to take Western/Israeli/Russian helps to make the J-XX truly fouth-generation (or fifth-generation using the Russian standards). Once introduced, the J-12's immediate rival will be U.S. F/A-22, JSF and India's MCA (Medium Combat Aircraft).

Chinese article about J-XX
Some military fans' words about J-XX
I think the best account, by most standards, is what we have heard from Sukhoi officials at MAKS 2003 about the JXX (remember, Sukhoi is assiting in the development due to lack of funds to Sukhoi from Russia). According to them, it is a full-fledged 5th Gen. (Stealth) fighter. It is expected to have advanced stealth characteristics (it greatly resembles the F-22) and is expected to be finished (my take on this statement is ready to begin prototype phase) ~6 years after the F-22 enters service (putting it around 2012 for prototype, and 2015-2018 for production). They classified it as an F-22 class fighters (whether by weight or tech has yet to be seen). Also, it was stated that the JXX is far ahead of PAK-FA (in terms of pace...no mention of tech).
The J-13 (The F-22 style) is the only windtunnel model that is known to the public. It is widely believed that the J-12 (the J-10/Mig-1.44/Tailless delta) was rejected. No-one I know of has stated anything on J-14 (Triplane style), but it is my belief that we will see an F-22 style JXX.
Some military fans' words about J-XX
Authoritative sources from the Chinese military aviation industry Group One told Kanwa that some major progress had been made in the development of the sub-systems used on the 4th generation stealth fighter, particularly the engine. The WS10A turbofan engines originally designed for J10A by Shenyang Liming Motor Company may very likely be installed on this 4th generation fighter for trial flight. The air test of WS10A had already been completed on SU27SK, including a total 256 test items.
Chinese Aviation experts emphasized that the Chinese version of TVC nozzle currently under development can perform 360 degree rotating. Earlier President Jiang Zemin inspected this project, which is one of the key aviation development programs during the "ninth five-year plan. Television images indicate this TVC nozzle can rotate at a range of +-15 degree, the source says that it has also been planned that the China-made TVC engine would be upgraded at appropriate time and installed on J10A in order to " improve the fighter's short-distance taking-off and landing performance and attain the maneuverability standard of F35."

China launches new stealth fighter project
JANE'S DEFENCE WEEKLY - DECEMBER 11, 2002
YIHONG CHANG JDW Correspondent
The Shenyang Aircraft Company has been selected to head research and development of a new heavyweight fighter for China's People's Liberation Army Air Force (PLAAF), according to a senior source at the China Aviation Industry Corp I (AVIC I).
Development of the engines and weapon subsystems for the fourth-generation fighter has been under way for some time, according to the source, who revealed that a number of design concepts have already been created. Wind-tunnel tests of these are about to start, including the two configurations pictured here. They show a twin-engine aircraft sharing some design traits with Lockheed Martin's stealthy F/A-22 multirole fighter, now undergoing tests with the US Air Force, such as the internal carriage of its weapon systems. The Chinese designs retain a more conventional wing, however, and use a single vertical tail fin.
AVIC I officials told Jane's Defence Weekly that the new aircraft - tentatively dubbed the J-X and possibly to receive the service designation J-13A - could use the WS10A turbofan engine designed by the Shenyang Liming Motor Company during its development and trials process.
In development for more than a decade, the WS10-series power plant completed air trials earlier this year with an Su-27SK (NATO reporting name: 'Flanker-B') fighter. The WS10A is scheduled for introduction with the PLAAF's new J-10A fighter, which has yet to be formally unveiled.
Continuing research into advanced control techniques is expected to in time allow the air force to field WS10A-powered J-10A and J-X fighters equipped with thrust-vectoring nozzles offering improved aircraft manoeuvrability.
Chinese television has shown images of President Jiang Zemin inspecting this project. The concepts indicate that the thrust-vectoring nozzle can be deflected by up to ±15º in any direction. Perfecting thrust-vectoring flight is one of the key aviation development programmes within Beijing's current five-year plan - a cap ability tipped to "improve the J-10A's short take-off and landing performance and [enable it to] attain the manoeuvrability standard of the F-35 Joint Strike Fighter", said one industry source.
An assessment of potential multi-function fire-control radar systems for the new stealth fighter is also under way, with candidates including China's indigenous Type 1473 design. According to an industry source, this has a search distance of 150km and can track up to 15 targets, attacking between six and eight of them simultaneously. The design is currently undergoing upgrade to allow for the integration of a phased-array antenna.
Another option is the Russian Zhemchung system, which could allow a future naval variant of the J-10A to deploy advanced weapons such as the Kh-31A (AS-17: 'Krypton') medium-range anti-ship missile. In addition to planning its own active and passive phased-array antenna design, China is giving consideration to Russia's Pero active antenna, and has also already received 20 980mm slotted antenna sets from Russia.
While AVIC I sources will not speculate when the new fighter might make its first test flight, a debut around the end of the decade could be expected if the project matches the development process for China's J-10A and J-8D projects. Further impetus has been placed on the new programme, however, through Zemin's encouragement that relevant weapons and technologies be acquired from Russia and Ukraine. Zemin has also committed future funding for the J-X concept's continued development.
In a related development, an authorative source within China's military industry has also confirmed to JDW that the air force's first 10 AL-31FN-engined J-10A fighters were deployed with the country's Nanjing Military Command during August 2002 for training activities. The PLAAF's first two-seat J-10B fighters will enter manufacture next year, featuring enhanced air-to-ground and maritime attack capabilities.
