Chengdu J-20 5th Generation Aircraft News & Discussions

Just imagine, the second line with J-31 and then SU30... damn force!
No Su-30...
Even J-11B can perform better than Su-30 in PLAAF/PLAN...

What is the exact role of this aircraft? always seems like too bulky ... too wide too long with small canopy...
The size of J-20 is not bigger than that of Su-27.

Oo
What is the exact role of this aircraft? always seems like too bulky ... too wide too long with small canopy...

Optical illusion caused by low vertical height of the canted tails and its relatively small size. Putting on the vertical tails of Flankers or the huge tails of F-22, this air craft instantly becomes smaller and slimmer than before.

Next gen fighter jet forthcoming in great power competition: J-20 chief designer

A revolutionary, cognition-subverting next generation fighter jet, characterized by long-range, high capabilities in penetration, awareness, firepower and fast decision-making, is about to come into being amid great power competition, according to a recent paper by the chief designer of China's J-20 stealth fighter jet.

Artificial intelligence is a key field to help pilots process vast information and make decisions in complicated battlefield environments, it said.

Amid great power competition and the commissioning of more and more fourth generation fighter jets (or fifth generation under US classification, which includes China's J-20, US' F-22 and F-35), there have been extensive discussions on the changes in types of warfare, and the development of post-fourth generation fighter jets, said Yang Wei of Aviation Industry Corporation of China (AVIC), in a paper published in Acta Aeronautica et Astronautica Sinica, a Chinese monthly journal on aeronautics, last month.

Yang is the chief designer of China's first fourth generation fighter jet, the J-20.

In the paper, Yang said that in older generations of fighter jets, maneuverability used to be the deciding factor, but this concept is becoming outdated with the development of advanced medium-range air-to-air missiles with their beyond-visual-range attack capabilities.

Information has now become the deciding factor, as modern fighter jets focus on gaining more information with the help of AESA radars and data chains, while also reducing opponents' ability to gain information, including using stealth technology and electronic countermeasures.

When aircraft can get more information with these advanced devices, pilots must have extensive knowledge, sharp analysis and sound decision-making to put them to use.

Yang said artificial intelligence will help pilots process the information, and help them become mission objective-oriented.

Each step in the original observe-orient-decide-act (OODA) loop in the air combat decision-making process will feature artificial intelligence's assistance, the paper said. "Intelligence becoming the deciding factor" will be the essence of what Yang calls an OODA 3.0.

Citing foreign projects, Yang said that a future fighter jet will generally require a longer combat range, longer endurance, stronger stealth capability, a larger load of air-to-air and air-to-surface weapons, and the functionality to provide its pilot with easy-to-understand battlefield situation images and predictions. In an integrated system, the aircraft should be able to form a network, draw real-time integrated situational images, create multiple attack routes, and transmit target information across mission areas in real time.

Yang's vision could indicate what China's future fighter jet might be like, a Chinese military expert told the Global Times on Monday under the condition of anonymity.

Usually the Chinese military simultaneously equips a current generation of weapons, develops a next generation, and conducts pre-study on a further generation at the same time. So as J-20s are being commissioned into the Chinese Air Force, the next generation fighter jet must have already started development, the expert said.

China is eyeing to develop a next generation fighter jet by 2035 or earlier, which could feature laser, adaptive engines and the ability to command drones, reports in early 2019 quoted Wang Haifeng, another senior designer at AVIC who participated in the development of the J-20 and J-10 fighter jets, as saying.

Su-27 bigger on overall length, wingspan & surface area. But the fuselage density, thickness, the J-20 is bigger than Su-27 that is quite skinny with engines spread apart and forward fuselage sitting higher. Your photo of J-20 lining abreast in front of J-11B shows the big difference.

Still publishing articles on behalf of avic. Looks like Indians were totally out to lunch on him being sacked
 

Korean KFX is fake model kit that doesn't fly and shouldn't be on this list. Japanese ATD-X is just a trainer aircraft that copied design from F-22 and is not stealth therefore it shouldn't be here neither.

The YF-23 is 67ft long and 12ft height, it looks small compared to J-20. T50 took design from YF-23, should put them next to each other.
 
Here is the full paper the article was referring to by Yang Wei. If a member would be so kind to translate the key details of this paper, that would be awesome!
This paper introduced the full-scale aircraft ground strength test and its requirements and analyzed the new problems and challenges in the test. Through the top-level planning for the test, new design mode and advanced loading technology are adopted to develop the overall technical scheme from the aspects of test boundary conditions, integrated platform, power system, measurement and control, and damage detection and monitoring. A number of new technologies, such as full-hard single-side bidirectional loading technology, test comprehensive platform design technology, boundary condition simulation technology, and power system design technology, have been studied and applied, which have improved design efficiency, accelerated test implementation speed, and improved test safety and reliability. These new technologies of this project have been successfully applied in the full-scale aircraft static/fatigue tests. The results showed that the test systems are safe and reliable, indicating that the test requirements and expected objectives have been achieved. The technologies have made great progress in the full-scale aircraft ground strength test, and the results have provided a high reference value for subsequent tests.

And this is a plain stupid ignorant post :mad::crazy::hitwall: since the KFX is in no way fakes, its prototype is just in final assembly, the Japanese ATD is no trainer but a test bed and the Su-57 was never based on the YF-23's design.
 
Su-27 bigger on overall length, wingspan & surface area. But the fuselage density, thickness, the J-20 is bigger than Su-27 that is quite skinny with engines spread apart and forward fuselage sitting higher. Your photo of J-20 lining abreast in front of J-11B shows the big difference.
What is you talking about J20 has length of 66 feet and Chinese flankers have a length of 72 feet J20 definitely smaller than Chinese flankers but larger than rest of the 5th gen jets (F35/f-22/su57) there was lot of pictures ( satellite) side by side with Chinese flankers showing j20 is smaller than Chinese flankers in this vary thread
