Love the pictures and the details. Bird looks amazing. I have few questions.

1. Is there any development towards adding stealth component to the canopy? when I see an F22, the canopy kind of glows and read somewhere that it has some stealth features.Even Rafale has it if i am not wrong.
2. Whts the thing just under the nose cone. I am no aerodynamic expert but would that not increase the RCS?

some earlier post in this thread...



on the Airshow China 2016...the newly founded Aero Engine Corporation of China（AECC）also demonstrated something ...

the three A9 actuating cylinders of TVC system...

and the brief functional diagram explained by someone ...the XXM of DS forum.

-------------

it is said that at this moment, the primary TVC project is related to the WS-15 Engine project which is also the genuine engine for J20 project... it will take another a couple of years to see the TVC on J20 if it goes well...

It's called ETOS or EODAS, you would google it.

Whenever i see these flanker Chinese clones i always wonder where would Russia's economy would be had China actually paid for Licenses/Royalty or actually bought these aircraft starting from J7 to whatever these photocopies are called now....and why in hell mighty USSR or present Russia allowed that to happen ?

The Russians only care about the money. Chinese are still buying weapons from them actually keeping them in the #2 arms exporter spot they buy so much. They aren't exporting them to compete with Russia so the financial loss isn't enough to get them outraged. Considering how much money China has pumped into Russian oil and gas industry it is those funds that keep Russia tapping their harder to get reserves as the easy ones dry out.

Well, think about how those foreign drug companies would be profitable if India pay the fair amount for their drug patents.

and why in hell mighty USSR or present Russia allowed that to happen ?

For USSR, that was not a issue for her at all, it took Chinese more than 20 years to digest her 1960s technologies;
For Russia, well, they were compensated from other contracts.

I don't agree with the statement you just made at large but don't want to discuss that in this forum...barring very few exception most of the world agrees on India's ethical behavior in all aspects.

Like i mentioned even if you disagree i would not like to debate any further on this forum.........................30 Character

Meta-materials and the J-20
AIR

It was in his interview at the People's Assembly Palace in front of dozens of journalists that YANG Wei, chief engineer of the J-20 program, spoke quickly about the use of "meta-materials and composites" on the plane. Chinese fighter of last generation.

Without giving any details as to the exact part or parts of the aircraft that benefit from the unusual physical properties of this kind of material whose research is very active today, the "revelation" of YANG generated a lot of enthusiasm and speculation. But what do we really know about this subject?



Long associated with the term of invisibility, thanks to their negative refractive index, meta-materials are macroscopic and three-dimensional composite materials, artificially designed with a periodic architecture. This carefully researched combination then has electromagnetic properties that are not found in a natural material.

We then talk about concrete applications such as invisibility cloak in infrared or visible light, or a radome with negative index to make compact antennas and directives ... etc.

Meta-material studies in China have started since 1989, if not earlier. If we believe in the number of R & D publications made public, which goes from just 200 in 1989 to more than 11,000 in 2014 before falling to fall below the 4,000 mark in 2017, the Chinese focused on applications of these "super-materials", literal translation of 超 材料 in Chinese, in the optical field, electromagnetic, seismic and acoustic.


The number of Chinese R & D publications on meta-materials between 1989 and 2017

The first link that could be established between the meta-materials and the J-20, for its part, dates back to 2017, at least according to the officially published elements. In fact, we learn that a strategic partnership has been signed between the 611 Institute of the AVIC Group, a design office responsible for the design of the Chinese fighter plane, and the Kuang Chi Group (光启), a Private Chinese founded in 2010 in Shenzhen by five doctors and specializing in meta-material, aerospace and artificial intelligence. The two entities signed an agreement to jointly develop "functional and structural aviation" products (先进 航空 功能 与 结构 产 产))), such as advanced antennas, radar electronics, data link and infrared equipment.

The chief engineer of J-20 is also part of the Scientific Committee of the "State Key Laboratory of Metamaterial Electromagnetic Modulation Technology", a national laboratory based on Kuang Chi teams and approved by the Chinese Ministry of Science and Technology in 2011. The structure, now employing 23 doctoral graduates, is inaugurated in 2015 before successfully passing the quality audit of the national 863 program in September 2017.

We also learn that the products made in metamaterials have not only been applied on the J-20 but also entered into service within the navy and the force of Chinese rockets, we can cite for example structural parts, windows compliant and specific antennas. The laboratory has also launched new research projects in 2017, such as low-permeability technology for all high-permeability spectrum, for example.

For now, it's unclear which J-20 elements were made with metamaterials, but Kuang Chi's booth at the last Zhuhai Airshow 2016 probably gave us some guidance. Indeed, one could see for example structural grids, SATCOM antennas, a motor air duct, the wing, the radome with selective stealth and anti-icing panels ... etc.

With announcements of this type that provide a little more detail on the aircraft, and new variants such as the onboard version and the one with Chinese jet engine vector, the program J-20 we probably still reserved other surprises to come.

To be continued.

The reality-defying "reverse engineering" claim aside; you do know that the Mig model pictured in your post is a Mig 31 and not the Mig 1.42 prototype right?

whats right of mig 31, J (joke)20 fighter??? or mig 1.44/1.42????

 

[Hari Sud]

Nothing new!

We all knew about Chinese technology which is reverse engineered or copied, but never 100%.

 

[Bleh]

What's right of mig 31, J (joke)20 fighter??? or mig 1.44/1.42????

Oooooh savage!

Anyway, doesn't matter. They have an operational fighter claimed to be a "stealthy 5th gen" right now & Russkis don't...

 

[south block]

there is nothing reverse engineered or copy..chinese pay huge money & use trade to get know how from Russia, Ukraine & west.

True!
Legend has it, the J-11 looking like Su-30 is pure coincidence...

Chinese Air Force's J-20 Fighter First Offshore Fighting Training
Author: North Youth Time: 2018-05-09 16:12

China Air Force spokesperson Shen Jin University announced on May 9th that China’s newly developed stealth fighter, the J-20, has launched its first real battle on the sea in recent days. Military training will further enhance the Air Force's comprehensive combat capabilities.

　　The spokesperson briefed the Air Force on the in-depth study and implementation of Xi Jinping's idea of strengthening the military. In accordance with the strategic goal of "a unity of air, space, and defense," the Air Force's high-tech weaponry has developed into a system in recent years, and a series of new fighters have been put into training in the new era. He introduced that after the J-20 fighter planes were equipped with Air Force combat troops, the flying talents grew steadily, practical training was gradually carried out, and air combat training was conducted in combination with J-16, J-10C and other multi-type fighter aircrafts in the actual combat background. The exercises played an important role in providing strong support for the Air Force’s new combat capability.

　　A spokesperson for the Air Force stated that the J-20 fighter's deployment of air, space, and practical training will help the Air Force better shoulder the sacred mission of safeguarding national sovereignty, security, and territorial integrity.

The newly integrated helmet featuring a HMD:

Note the position trackers (small bumps on the helmet) that allow for integration with the aircraft's distributed eletro optic passive detection system or the IR detection system.

A model of the same helmet displayed at last year's Zhuhai airshow:

We're slowly seeing the incremental integration of advanced sub-systems on the J20. Would love to see the complete package once the programme reaches FOC.

'Not So Invisible After All': India's Su-30 MKI Manages to Detect China's Top Stealth Jet

China's fifth-generation Chengdu J-20, its most advanced fighter jet, has recently successfully completed its first maritime combat training. The latest Chinese jet has been in development since 2002 and entered into service in 2017.

A Sukhoi Su-30MKI (NATO reporting name Flanker-C) of the Indian Air Force reportedly managed to detect the latest Chinese Chengdu J-20 jet fighter, which is supposed to be a top-of-the-line stealth aircraft operated by the People's Liberation Army Air Force (PLAAF), reports Indian Defence Research Wing. According to the outlet, when the new Chinese jets where conducting flight training over Tibet, Indian pilots on Russian-made Su-30MKIs managed to detect and track them from Indian airspace.

"The Sukhoi's radar can see them. The new Chinese jets are not so invisible after all. No special technology is required to detect the J-20, as it can be detected by ordinary radar stations," Indian Air Force commander Arup Shaha said.

The Chinese Chengdu J-20 has been in development since 2002 and was made using stealth technology. It was entered into service in March 2017, with nine prototypes and two pre-serial units built so far. The J-20 has recently successfully completed its first maritime training exercises.
