The engine nozzle looks huge. Could it be domestic engine installed for testing?

The Chengdu J-20, the PLA Air Force’s first fifth-generation stealth fighter still has three major weaknesses to be overcome before it is ready to enter service, China’s Global Times reports.

The first major weakness is the engine; China is currently unable to design and produce engines powerful enough for advanced fighters. The prototype J-20 currently has the Russian-built AL-31F engine. However, Chinese pilots flying J-10 fighters using the AL-31F have experienced several accidents related to its poor reliability.

Furthermore, if the PLA continues to rely on Russian-built engines, it will never be able to operate its fighter free from the influence of Moscow, Global Times said. The article suggested therefore that Chinese engineers should design their own engine through studying the Russian technology. This would be far from the first instance of Chinese engineers back-engineering Russian technology.

Second, the design of the J-20′s fuselage seems unfitting. While the weapons bay has been designed large enough to carry various types of payload, the aircraft’s wings appear too small. A lack of proper aerodynamic design configuration compromises the stealth capability and maneuverability of the J-20, the report said.

Finally, Global Times said the J-20′s two engines are positioned too close with each other and could cause a dangerous vortex when both are running at high speed.

In sum, the J-20 is some way away from entering service, the report concluded, noting that in Western countries it is common for it to take between five and eight years between the design of a fighter prototype and the aircraft entering service.

Those are prototypes, production versions will be different.

Nothing to see here. The article in question is a reprint of a WanChinaTimes article. A Taiwanese newspaper known for its biased views and inaccurate reporting on China matters. The WanChinaTimes article's main source is a Global Times article from China but fails to give a link to the original article of the Global Times. So that the readers can judge for themselves.

Relax, the mass production version of J-20 will more look like this↓, WS-15 not AL-31 jet engines.

Let's waiting for J-20 N.o2003 come out, it will be China's YF-22 ==> F-22 change. Soon J-20 N.o2003 will out at ChengDu SAC, rumors said N.o2003 maybe the production version of China J-20.

Bs story....get ready for war....

I don't know much about jets but my analysis on three problems are..
1) yes engine is problem...
2) wings are small I think person who had with article has not even seen pictures of J-20 it has huge wings.
3) engine in raptor are also very close to each other.

It's still prototype not in production...
