Zitat:Vielelicht ist die neue J-31(?) auch nur eine Rückversicherung gegen ein Scheitern der J-20. Kleiner, billiger, von der Auslegung wie eine F-22/F-35 und damit scheinbar risikoärmer......

Zitat: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.

Zitat:Third Chengdu J-20 prototype flies

By DX on 2 March 2014

The third prototype of the Chengdu J-20 stealth fighter made its maiden flight successfully on Saturday 1st March. According to the witness report on Chinese social media, the J-20 prototype “2011″ took the sky at about 12:00 local time, escorted by a Chengdu J-10S two-seater fighter. The entire flight lasted about 30 minutes before the aircraft landed safely.

Der Artikel sagt aus, das die chinesische Luftwaffe an der J-31 wenig Interesse habe.
Ich halte es daher für möglich, das man sich um einen Export der J-31 bemühen wird. Da käme auch eine verlängerte Variante - womöglich zur Schiffsbekämpfung optimiert - ins Spiel.
Potentielle Exportkunden gäbe es ja genug.

Zitat:J-31 stealth jet gets bad reviews after Zhuhai Airshow flight

The criticism of J-31, China's second fifth-generation fighter jet, mainly stems from the dark exhaust emitting from the jet's engine, which indicates the engine's poor efficiency in burning fuel.

Meanwhile, PLA Navy Rear Admiral Zhang Zhaozhong said in a speech in Xiamen on Nov. 17 that China's reverse engineering still has its limitations, and that it will take the country another few years to achieve a breakthrough in developing its own engines.

Zhang said the development of a jet engine involves mechanics and digital control, and the former is far more easy to master than the latter. "This part is too difficult and not something that can be achieved successly in a short time," he said.

Zhang also believes that the J-31 jet is too heavy.

Zitat:First Official confirmation of negotiation for FC-31 purchase for PAF

PAF wants to buy Chinese stealth aircraft: minister

ISLAMABAD: The Pakistan Air Force (PAF) has expressed interest in procuring fourth generation stealth fighter aircraft FC-31 from China.

Minister for Defence Production Rana Tanveer Hussain told Dawn on Friday the matter was being discussed with Chinese authorities.

It is for the first time that a senior government functionary has confirmed talks with China over purchase of the longer-range stealth aircraft — an issue that has been a subject of speculation in defence circles since the 10th edition of the Zhuhai Air Show (China) held earlier this month, when the aircraft was unveiled.

Second radar cross-section test range identified in China

Zitat:Key Points

-Airbus Defence and Space imagery captured in 2016 shows a new radar cross-section test range in China

-A J-20 full-scale test article is present at the new test range, with apparent design changes suggesting either a new powerplant installation or a new aircraft variant under evaluation

IHS Jane's recently identified a radar cross-section (RCS) test complex in China. Airbus Defence and Space imagery captured on 24 April shows a recently completed test range northeast of Dingxin Airbase (AB) - the second new test site to be identified in the East Asian nation. The first one is located southwest of Beijing near Gaobeidian. A third possible site, predating the new complexes, is situated near Luoyang.

The location near Dingxin AB is well suited for a signature evaluation complex, with flat terrain and a lack of man-made or natural obstructions near the facility. Additionally, the configuration of the J-20 full-scale RCS test article present suggests design changes may be forthcoming to China's fifth-generation stealth fighter.

Along with the Gaobeidian RCS complex, the Dingxin RCS complex illustrates China's increasing attention to low-RCS aircraft design. The Dingxin RCS complex was constructed after the Gaobeidian site, which was built in the 2009 timeframe - perhaps in an effort to establish an RCS test range in a more secure location.

Der welterste Stealth Fighter-Zweisitzer kommt aus: China

Chinas erster Stealth Fighter, die Chengdu J-20, existiert mittlerweile in dreistelliger Stückzahl. Doch nun rollte in Chengdu ein ganz besonderes Exemplar aus der Halle: Vorhang auf für den weltweit ersten Kampfjet der fünften Generation mit Zweimann-Cockpit. [...] Was da auf verschwommenen Fotos aus Süwestchina über den Werksflugplatz der Chengdu Aerospace Corporation rollt, ist der erste Prototyp einer zweisitzigen Variante des Stealth Fighters Chengdu J-20. Noch ohne Lack, nur gelb grundiert, bewegte sich der neueste Kampfjet made in China, aus der Ferne von Kameras begleitet, am 27. Oktober aus eigener Kraft über das Rollfeld. Damit hat China ab sofort etwas, was sonst auf der Welt noch niemand hat: ein Kampfflugzeug der fünften Generation, in dessen Cockpit zwei Personen Platz finden.
