One more copy paste from the world's biggest XEROX copier machine.
It is now in the open that J-20 is a copy of MIG1.44, which they have now showcased at MAK airshow . Sometimes I wonder how Russia even tolerates this THIEF of a nation.
IDN TAKE CHINESE J-20 IS THE CANCELLED SOVIET MIG 1.44/1.42 STEALTH FIGHTER
TUESDAY, AUGUST 11, 2015 BY INDIANDEFENSE NEWS
The remarkable design resemblance between the two fighters is just not any coincidence - The J-20 is heavily based on the Mikoyan design bureau’s cancelled ‘Project 1.44’ to develop a fifth-generation fighter for the Russian Air Force
Mikoyan Project 1.44/1.42 Flatpack
The Mikoyan Project 1.44/1.42 Flatpack was a technology demonstrator developed by the Mikoyan design bureau. It was the Soviet Union’s answer to the U.S.’s Advanced Tactical Fighter (ATF), incorporating many fifth-generation jet fighter aspects such as Advanced Avionics, Stealth Technology, Supermaneuverability, and Supercruise. The design’s development was a protracted one, characterized by repeated and lengthy postponements due to a chronic lack of funds; the MiG 1.44 made its maiden flight in February 2000, nine years behind schedule. The Mikoyan 1.44 was eventually cancelled in 2000.
Chengdu J-20
The Chengdu J-20 is a Stealth, twin-engine fifth-generation fighter aircraft prototype being developed by Chengdu Aircraft Industry Group for the Chinese People's Liberation Army Air Force (PLAAF). The J-20 made its first flight on 11 January 2011, and is expected to be operational in 2018. China's J-20 platform has the potential to be a capable, long-range strike system in the Asia-Pacific region, but a number of technical challenges will need to be overcome before production can begin.
Origins of the J-20 came from the J-XX program which was started in the late 1990s. A proposal from Chengdu Aircraft Industry Group, designated "Project 718", had won the PLAAF endorsement following a 2008 competition against a Shenyang proposal that was reportedly even larger than the J-20.
Flight Testing
On 22 December 2010, the first J-20 prototype underwent high speed taxiing tests outside the Chengdu Aircraft Design Institute. On 11 January 2011, the J-20 made its first flight, lasting about 15 minutes, with a Chengdu J-10S serving as the chase aircraft.
Conclusion
The J-20 is heavily based on the Mikoyan design bureau’s cancelled ‘Project 1.44’ project to develop a fifth-generation fighter for the Russian Air Force. The layout is virtually identical, with the main differences being the position of the intakes and the larger fuselage on the J-20. To give due credit to the "MASTERS OF CLONING", the J-31 is the spitting image of the Lockheed F-35 Lightning II – America's latest and greatest technological creation. However, the new project, being referred to as the Shenyang J-31, paints a much more disturbing picture than the J-20. The J-20’s heritage could be traced back to an abandoned Soviet project that was deemed irrelevant before it even got off the ground.
Why is this similarity to the F-35 worrisome? Because as recently as 2010, Lockheed Martin publicly admitted that six to eight of its subcontractors had been “totally compromised” by cyber-intrusions. Later it emerged that BAE Systems, Britain’s largest defence contractor and a key partner in the F-35 programme was among the breached firms. The proof, however, is in the pudding – the J-31 resembles the F-35 in everything but the engine configuration. The intakes are identical, as is the nose, wings and control surfaces. Note that despite choosing to use all-moving vertical stabilisers on the J-20, the J-31 features rudders like the F-22 and F-35.
The J-20 or the J-31 will take years before it enters operational service, and even when they do, they are not expected to match Western sophistication in propulsion, sensors, avionics, and pilot interface. What is inescapable, however, is that basic airframe design and construction of fifth-generation aircraft is no longer an area where the West retains mastery. Whether China acquired this expertise honestly or not is moot. The fact is that they have put two prototypes into testing in one-fifth the time it took either Russia or the United States, and are catching up everywhere else. (Credit: Angad)

China's J-20 is a stealth fighter. The Mig 1.44 was not.
China's J-20 has air intakes on the side. The Mig 1.44 has air intakes below its fuselage.
China's J-20 has DSI intakes. The Mig 1.44 does not.
China's J-20 has stealthy S-ducts (or serpentine ducts). The Mig 1.44 does not.
China's J-20 has angled vertical stabilizers for stealth. The Mig 1.44 does not.
China's J-20 has an AESA radar. The Mig 1.44 does not.
China's J-20 has planform alignment. The Mig 1.44 does not.
China's J-20 has its canards directly in front of its main wings. The Mig 1.44 has canards located at a higher elevation than its wings.
China's J-20 has internal weapon bays. The Mig 1.44 does not.
In conclusion, China's J-20 has no relation to the Mig 1.44. The only thing you can claim is that they are both delta-wing fighters. However, many aircraft worldwide are delta-wing fighters (such as the Eurofighter, the Rafale, the F-14 Tomcat, etc.).

It is very much possible. The russian military did not choose MiG's design and MiG was broke.
The russians later made/is making MiG LMFS out of 1.44.
So with the plans and data from 1.44 and the stolen data for f-35, j-20 comes to life.
Note: I'm not criticizing the Chinese. Beg, borrow, steal whatever it takes to achieve the aim.

Whatever you have listed is a car company doing facelift of existing models. For example changing headlamps, tail lamps, a new grill, a new dash board, upgraded engine with turbo, etc. and voila its a new car. Mig 1.44 developed in response to F-22 and the above was a TD which was to be converted into a stealth fighter but then USSR was finished and this model was scrapped for SU 50 PAKFA.

You are extremely ignorant.
You cannot tell the difference between a stealth fighter and a fourth-generation antiquated fighter.
I listed the important differences that exist between China's Chengdu J-20 stealth fighter and a legacy fighter.
If you can't comprehend the vast design differences then it is due to your complete ignorance about stealth fighters.
No one claims an F-22 is similar to an F-16. However, you are making such a claim.
There is a world of difference between the Chinese Chengdu J-20 and a legacy delta-wing fighter.

I hate it when dumb people make ridiculous claims about China's Chengdu J-20 stealth fighter. Let's go over the key concepts again.
1. China's Chengdu J-20 obeys continuous curvature. This deflects radar waves away from the J-20. The Mig 1.44 does not obey continuous curvature design.
2. China's Chengdu J-20 follows planform alignment. This minimizes the angles of radar reflection. The Mig 1.44 does not follow planform alignment.
3. China's Chengdu J-20 has serpentine ducts (or S-ducts). This minimizes radar reflection from the turbofan engine blades. The Mig 1.44 does not have S-ducts.
4. China's Chengdu J-20 has one underside internal bay and two side weapon bays. This minimizes radar reflections from weapons. The Mig 1.44 has no internal bays and its exposed weapons reflect radar waves.
5. China's Chengdu J-20 underside follows stealth facet design. Radar waves are bounced away like a mirror. The Mig 1.44 has lumps on its underside and it is not mirror smooth like the J-20.
6. China's Chengdu J-20 is covered with a stealth coating, including the engine pods. The Mig 1.44 has no stealth coating. The Russian Pak-Fa also has no stealth coating over its engine pods. The Russians have not solved the heat dissipation problem when a stealth coating envelops the metal engine pods.
7. China's Chengdu J-20 has advanced glass displays. The Mig 1.44 used old CRT screens.
8. China's Chengdu J-20 has DSI intakes for smooth supersonic flight. The Mig 1.44 needs mechanical ramps.
9. China's Chengdu J-20 has an AESA radar. The Mig 1.44 has an old mechanical radar.
10. China's Chengdu J-20 has EOTS. The Mig 1.44 has no such sensors. The Pak Fa also lacks an EOTS.
11. China's Chengdu J-20 has EODAS. The Mig 1.44 has no such sensors. The Pak Fa also lacks an EODAS.
12. China's Chengdu J-20 has canards horizontally aligned with its wings to minimize the surface area exposed to oncoming radar. The Mig 1.44 has its canards and wings at different elevations, which maximizes radar reflection.
13. China's Chengdu J-20 has angled vertical stabilizers to deflect radar away from an emitting source approaching from the side of the aircraft. The Mig 1.44 has non-stealthy vertical stabilizers to maximize the radar return to an oncoming aircraft from the side.
Angled vertical stabilizers have different fluid dynamic characteristics than non-stealthy vertical stabilizers.
14. China's Chengdu J-20 is designed to supercruise. The Mig 1.44 was never designed for supercruise.
In conclusion, only someone that is completely ignorant would claim the Chinese Chengdu J-20 and the Mig 1.44 are similar. Aside from being delta-wing fighters, there is no similarity between the J-20 and the Mig 1.44.
1. China's Chengdu J-20 obeys continuous curvature. This deflects radar waves away from the J-20. The Mig 1.44 does not obey continuous curvature design.

You are wrong and I can prove it:
J-20 has a fuselage, so does mig 1.44
J-20 has canards, so does mig 1.44
J-20 has wings, so does mig 1.44
J-20 has a fuselage, so does mig 1.44
J-20 has a cockpit, so does mig 1.44
J-20 has a landingear, so does mig 1.44
J-20 burns jet fuel, so does mig 1.44
Hell, its a copy!!

What is not beautiful about it. See it flying, the aerial display speaks for itself.
You are such a hypocrite. Why don't you criticize your daddies for Tu-144 "Concordski" or Tu-160? What about Ilyushin-86 "airbuski"?

Here is why I get annoyed when someone ignorant claims the J-20 and the Mig 1.44 are similar.
The Chinese Chengdu J-20 and the Russian Mig 1.44 lie on opposite ends of the air superiority spectrum.
The Chinese Chengdu J-20 can easily penetrate current air defense networks. X-band and upper S-band radars are useless against the Chengdu J-20.
On the other hand, the Mig 1.44 has zero chance of penetrating current air defense systems. An X-band radar would easily pinpoint the location of the Mig 1.44 and a SAM would shoot it down.
In conclusion, there is no functional or design similarities between the Chengdu J-20 and Russian Mig 1.44. Let me give you another easy example. Look at the picture of the Mig 1.44. Do you see those weapon pylons hanging off the wings? Those are not stealthy. In contrast, the Chengdu J-20 has carefully-designed internal weapon bays to hide its weapon payload from radar detection.

Some of the Chengdu J-20 stealth characteristics. There isn't enough room on the picture to label everything. For example, the bottom half of the J-20 nose is faceted for stealth. In contrast, the upper half of the nose obeys continuous curvature.

The F-35 has been a failure.
The space for the vertical fan exists on all three variants. This has lead to a less-stealthy F-35 design.
In contrast, the original unmodified F-35 prototype had a clean design. Now, the F-35 is lumpy and not stealthy.
Also, the addition of a gun above the left air duct is also not stealthy.
The F-35 lift-fan space in the middle of the fuselage has led to a wide fuselage and bulky wing-roots.
The F-35 is a compromised fighter and they really need to start over.
