Chengdu J-20 5th Generation Aircraft News & Discussions

[Asoka]

What is the J-20?

To put it simply, J-20 is a very long range fighter/striker/intercepter with a unique and creative combination of world's first 5th generation fighter, F-22's Stealth, Supercruise, Supermaneuverability and Situational awareness (4S), plus F-35's Electro-Optical Distributed Aperture System (EODAS), Electro-Optical Targeting System (EOTS), Adjustable Diverterless Supersonic Inlet (ADSI), 360 degrees Integrated Helmet and Display SightingSystem (360IHADSS) Combined with High Off-Boresight Missiles(HOBS), plus All Moving Vertical Tails (AMVT) of FA-117, and Adjustable Canards (AC) of Typhoon, Rafael, Gripen, and J-10, and a powerful Active Electronically Scanned Array (ASEA) radar with 2000 T/R modules.

All combined into a technological marvel of an unrivaled, agile, lethal and long range Air Dominance Machine (ADM).

Why you repeated same annoted images again & again

Why you repeated same annoted images again & again

Really, someone has already posted them? I don't know that. I am new to PDF. I just summarized the main features of J-20 in the caption and used the two pictures as illustrations.

Bro, ignore those back seat drivers, they're good in picking bones out of a cream cake, perhaps if they're the ones spending time and efforts surfing around to look for NEW, INTERESTING pictures, they will think otherwise LOL
Nobody is responsible for the satisfaction of these so-called readers, like it or not,
I DON'T GIVE A SH@T period

J-20 and J-10B

xxxxxxx

And you guys have any concrete evidence of using a domestic engine on the J-20, other than fanboy pics?

No need to get defensive.

Absence of evidence doesn't mean WS-15 does not exist, or haven't been tested on one of the J-20 yet. It simply mean China has choosen not to reveal its status at this moment.

An accomplishment for China that is enviable -- yes.

A technological marvel ? Not even hardly, but simply -- no.

Am not saying that to be mean to China as I have always praised the J-20, but there is nothing on the jet that is groundbreaking or new. Not even DSI.

Has anyone got a picture of J20 with canards not open...!!!!!!!!

Looks like a few days gone by and you have not gotten the appropriate help.

The correct word you are looking for is 'deflection'. Not 'open'.

The canard is a flight controls structure or element. It helps the jet uses aerodynamic forces to maneuver.

The definition of 'deflection' is away from a base or neutral condition. What you are looking for is the J-20's canards in a neutral position. In post 6720 you can see that.

So to use the proper aviation related terms and phrasings, it is 'deflection'.

Gambit said "but there is nothing on the jet that is groundbreaking or new."

There are things we can't see underneath the skin, since you or we have no access to the plane. For example, new coating materials, new structural materials, new design process, new manufacturing process, new testing procedure, new avionics or software, new self-defense measures or counter-measures.

Aerodynamically, the combination of a distantly coupled canard, and small edges between the canard and the main wings is a definitely a new innovation. It solved the problem that has long bedeviled designers, namely, how to achieve both subsonic and supersonic supermaneuverability using canards. Using this aerodynamic combination, J-20 will have both fearsome capability in both subsonic and supersonic speed.

I don't think most observers have realized the profound implication of this innovation yet.

The combination of 4S is ground breaking for F-22, although individually it may have accomplished in other planes first.

I say it is a "technological marvel " because it still got ample room for further development like the F-15, and Su-27 family so we don't know how it will end up in 20-30 years. Whereas F-22 has already stopped production, and F-35 has no more room for further development because it's already grossly overweight.

The biggest innovation is probably tactic, with very long range and stealth, J-20 could attack enemy's vital support planes such oil tankers, AWACS. This is really a game changer like the ability of FA-117 to penetrate enemy air-defense at will during the Gulf war.

This tactic is truly revolutionary. With every oil tanker down, several enemy fighters will dive into the sea, and if an AWACS is down, the enemy strength for the mission will be down by 50%. No oil tanker or AWACS have been lost in combat yet, but the prospect is truly scary for mission planners. This is even more effective than attacking the enemy's runways, because they can be repaired in matter of hours.

And China and Russia already have long range (300-400Km) missiles for just such purpose of attacking AWACS plane.

Remember, it was the Israel Air Force's excellent trainings and outstanding tactical innovations that destroyed the Arab air forces in previous wars. They claimed even if they switched planes with the Arabs, the results would still be the same.

When you said "closed", do you mean like the vertical canards of this F-16/CCV?

History
The first YF-16 (#72-1567) was rebuilt in December 1975 to become the USAF Flight Dynamics Laboratory's Control Configured Vehicle (CCV). CCV aircraft have independent or "decoupled" flight control surfaces, which make it possible to maneuver in one plane without movement in another -- for example, turning without having to bank.

The CCV YF-16 was fitted with twin vertical canards added underneath the air intake, and flight controls were modified to permit use of wing trailing edge flaperons acting in combination with the all moving stabilator. The fuel system was adapted, so that by transferring fuel from one tank to another, the position of the aircraft center of gravity could be adjusted.

The YF-16/CCV flew for the first time on March 16, 1976, piloted by David J. Thigpen. On June 24, 1976, it was seriously damaged in a crash landing. While still more than half a mile out, the engine suffered from a loss of power and in the resulting crash landing the landing gear collapsed. Repairs took over 6 months, and its flight test program was resumed in the spring of 1977. The last flight of the YF-16/CCV was on June 31st, 1977, after 87 sorties and 125 air hours had been logged.

A few years later, the F-16/AFTI program would capitalize on the experience gained from this CCV program.

I don't know about that claim. It has a larger air frame than the F-22 while having much less powerful engines. In addition, the USAF has operated stealth jets for at least 3 decades (4 if you count the SR-71). Even as far back as Vietnam War, the American pilots were aware of the need to present minimal radar return to the enemies when flying strike missions. J-20 represents a major leap forward for China, but certainly calling it an unrivaled air dominance machine is far fetched.
