Hogwash! If China has no experience in viable geometry? what is the FL-62 and millions designed patents filed?

It is more about that China haven't build an actual variable geometry plane that goes into service. The US (F-14), Russia (Mig-23), and EU (Panavia tornado) all have those experience, China doesn't.

Because it is bad and terrible concept and everybody is ditching it. To begin it add weight and complexity to the plane Other is concept of low level penetration is outdated with the proliferation of SAM!

If you look at recent trends in aviation, adaptive geometry (i.e, variable geometry v2) is a new thing, with the entire wing intended to be morphed around. Moreover, improvements in actuator technology (remember that China has the rare earth monopoly) could make it so that the effective weight costs of swept wings could be reduced.

It's an incredibly interesting direction, but one that China currently lacks technological maturity in.

Not necessarily true. If you need your aircraft to fly efficiently at sufficiently disparate operating conditions, variable geometry is still the gold standard solution, though costly. As you mention, for various reasons such requirements have currently diminished in importance, but that's not to say they can't come back if circumstances change. In WWI maneuverability was the top priority in a similar manner to the current situation, but in the meantime there were phases where it was markedly deprecated in favour of speed.

If the Pacific does become the dominant theatre of operations as many expect it to, the tyranny of distance could usher in a renaissance of speed.

Two academic papers of interest. They are beyond my ability to translate adequately. It'd be great if our Chinese speakers can summarize the important/interesting points.

First, a paper on a new structural load testing system for a "next generation fighter".

Here's the English abstract:
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.


The second paper is authored by Yang Wei, the chief designer of J-10 and J-20. He sketches out ideas and requirements of a 6th-generation fighter.

Below is the abstract:
Recent years have witnessed extensive discussions on the change of warfare forms and the development of post-4th generation fighters against the background of great power competition and batches of 4th generation fighters entering service. This paper reviews the origin of fighter generation classification and the driving elements behind each generational leap, outlining the evolution of Observe, Orient, Decision, Act (OODA) loops for air combat and proposing the essence of OODA 3.0. After a summary of the supportive and progressive relations among mechanization, informatization and intelligentization, it explores the dialectical relationship among autonomy and manned/unmanned, as well as that among platform, system of systems, and distributed operation, followed finally by a discussion of an agile and efficient development approach of future fighters.

Basically, most of the papers published in this latest issue of Chinese Journal of Aeronautics are related to J-20's research and development, including the first paper you quoted.

Below is the abstract:
on the second paper, i noticed the following key points:
1, OODA 3.0 is mainly about adding AI elements in each of the phases, but
2, given current technology maturity level, 6 gen fighter will be AI-assisted manned aircraft. Unmanned a/c will not be dominant
3, wrt the "Mosaic Warfare" concept, the author argues that in future combat, highly capable platforms are very critical, and they will not be replace by swarms of low-end, low-cost platforms
4, new procurement process and agile development methodology, will result in quick development and deployment of 6 gen fighter. The dev-to-initial-deployment cycle could be as short as five years.

Not sure if this belongs to this thread, but it seems like a good candidate. The first image appears to be an illustration from an academic paper that I cannot locate. It shows a design concept of what looks like a supersonic platform with canards and wings on the same plane (thus the edge alignment). It features no vertical tails. The second image doesn't appear to be from the same paper; it's probably a fan-made 3D model based on the illustration.

Next gen fighter jet upcoming 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.
