J-12/J-13

China’s two major fighter aircraft manufacturers, Shenyang Aircraft Corporation (SAC) and Chengdu Aircraft Industry Co. (CAC), are both working on advanced 4th-generation fighter designs that could enter the PLAAF service as early as 2015. While Shenyang has been engaged in a brand new F-22-class stealth fighter design known as J-12, Chengdu has been focusing its development effort on an enlarged twin-engine, stealth version of its J-10 fighter possibly designated J-13. Both development projects are believed to have benefited from Russian aviation and weapon technologies.

The Chinese aviation industry began the preliminary research for China’s 4th generation fighter programme in the mid-1990s. In 1998 the U.S. Office of Naval Intelligence (ONI) reported that an advanced F-22-class twin-engine stealth fighter known as J-12 was under development at SAC. Later in 2003 an Internet source photo revealed a fighter mockup for wind tunnel test which may be linked to the J-12 project. As more details of the fighter began to emerge, it was understood that the fighter will also be fitted with an internal weapon bay and possibly active phased array radar.

Considering China’s records in combat aircraft development, a project like the J-12 may prove challenging. It will involves technology advancement in a number of fields including materials, high-performance aviation engine, electronics, flight control software, and stealth technologies. A project of this scale will also require huge amount of investment and considerable knowledge of complex project and manufacturing management. While China may be able to benefit from some “off-the-shelf” dual-use technologies available in the commercial market, it will almost definitely seek assistance from its traditional military technology suppliers such as Russia and Israel. However, none of these two countries possess the experience of developing an advance fighter of this class.

Russian Sukhoi Company (JSC), which has developed close ties with Shenyang over the licensed co-production of its Su-27SK fighter as J-11, has been reportedly working with Shenyang in developing the next-generation fighter technology and sub-systems. Although Russia has yet been able to develop an operational stealth fighter, the J-12 project may benefit from its technologies in two particular areas: thrust vectoring engine and stealth design. China may also seek potential partners from Russia, Israel and Europe to co-develop avionics and weapon suites for its 4th-generation fighter aircraft.

J-12 (Jianjiji-12 Fighter aircraft 12) / F-12

Besides carrying on with the improvement of the J-8 series and the licensed production of the Su-27, the Shenyang Aircraft Company (SAC) is now engaged in preliminary research for the "No. 12" project for the development of the Chinese Air Force's main fighter aircraft for the 21st century. Also known as the "XXJ," this fifth generation PLAAF fighter, is currently projected to enter service in the 2013-2015 timeframe. The aircraft is projected to have a crew of two, is anticipated to be in same class as US F-22 fighter, probably based on significant Russian technical assistance.

The J-12 designation was apparently previously applied to a lightweight STOL fighter aircraft built at Nanchang in the late 1960s. With a first flight on 26 December 1969, reportedly somewhere between one or two and six airframes being constructed prior to the program's cancellation in 1978. Said to resemble a scaled-up MiG-15/17, it was in competition with the J-7 and J-8, though with a less robust weapon system

J-13 (Jianjiji-13 Fighter aircraft 13) / F-13

The genesis of the original J-13 was in 1971, when the 601 Institute began researching a new fighter aircraft for the 1980s to replace the J-6. The new aircraft used cantilever wings and fuselage side mounted air intakes - it resembled the French Mirage-F1. By the late 1980s the project continued, although the operational requirements had increased to match the Russian MiG-29 and American F-16 light fighters. In the early 1990s the project was finally abandoned because of the success of the Chengdu J-10 project.

Some sources suggest that the J-13 designation will be applied to the Su-30.

By late 2002 the Shenyang Aircraft Company had been selected to head research and development of a new heavyweight fighter for China's People's Liberation Army Air Force (PLAAF). Development of the engines and weapon subsystems for the fourth-generation fighter had been under way for some time, with a number of design concepts having been created. These include a twin-engine aircraft sharing some design traits with Lockheed Martin's stealthy F/A-22 multirole fighter, 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.

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. 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.

photos du J-12:
remarquez que l'avion n'a pas encore prix une forme définitive, des fois avec une seule entrée d'air, des fois avec deux entrées à la raptor! les tuyères aussi sont à la raptor ce qui est très improbable vu que les moteurs seront probablement russes

Images magnifique raptor!!

En plus c'est un appareil qui m'interesse bcp!! (le j12) Mais la en plus tu m'apprend qu'il y'en a un 2eme! le pied!!!

Il y'a un truc qui me chiffonne.... apparamment, les chinois ne cherchent pas la futivité totale a mon avis pour 2 raisons (d'apres les photos) : la premiere: les tuyeres ne sont pas "couvertes" a l'image du f22, la deuxieme : emport d'arme externe sur le croquis...

etrange... mais je me trompe peut etre...

au contraire, le projet J-XX est un projet d'avion furtif avec soutes interne, l'emport en externe c'est une option supplémentaire quand la furtivité n'est pas necéssaire, même le F-22 et le F-35 en une possibilité d'emport en externe.

pour les photos se sont pour la plus part des impressions d'artiste donc il est difficile d'en avoir une idée claire de ce nouveau chasseur, tu trouveras dans ses photos beaucoup de contradiction, ex:
Monoréacteur/Biréacteur
Tuyères style (Sukhoi)/Tuyères (F22)
...
mais je pense que ça sera surement un biréacteur avec des tuyères style sukhoi, car il sera doté de motorisation russe, la même que pour le Su 35BM et le PAK FA.

le f22 aussi n'est pas un avion furtive c'est un avion d'une tres faibles signature radar pour une furtivite il faut annuler les Gouvernes de direction et les Gouvernes de profondeur (le cas du B2) ou plus les inclinees vers l'exterieur et vers l'avant ou l'arriere (le cas du F117)

vous pensez que a terme, le j-12 et le j-13 seront exportables?

faudrait trouver des acheteurs dabord

à aujourd'hui on ne sait toujours pas si le projet J-XX va aboutir, ce n'est pas un secret que la chine ne maîtrise pas bien les technologies aéronautique, et donc pour développer un chasseur de 5ème génération elle est dépendante de la technologie russe qui est aussi en cours de développement et n'as vu le jour que partiellement.
souvenez vous que pour développer le J-10 qui est un chasseur de 4 génération la chine à fait appel à la technologie israelienne pour venir à bout de se projet.

Un avant goût de ce qui va bientôt sortir ou ce qui existe déjà....
