China shocks analysts by Flight Testing 5th gen JXX Stealth fighter

[Pilotasso]

whats funny is that F-22's dont even fulfil Australians needs. They need a long range strike fighter like the F-22 and a plane with better AA capability. F-22 falls short of this but F-35 is both of those things.

A size comparison chart.

 

For me from paralay is more realistic:smilewink:

As a Chinese, I know what Chinese people think. Thousands of years ago we were the strongest country in the world yet we didn't love the taste of blood like the romans or the arabians (no offense). Today I don't think we will be changed especially half of the economy of China is beasd on orders from abroad.:)

 

Sorry I have to disagree. China was very warlike during the end of the Han Dynasty and Three kingdoms era, and was considered to be more militarily powerful than the Roman Empire (200 AD). Qin Dynasty as well, with the well known emperor who unified China with his million man army... and Ming Dynasty for driving the Japanese Samurai out of Manchuria and Korea. If anything, I think China is RETURNING to being a more militaristic country after being peaceful and learning the hard way from European imperialism and the Japanese in WWII. It is unfair to say that other civilizations are more blood thirsty. Every advanced civilization that has existed has been blood thirsty at some point.

I admit I was being racism and I apologize. But it is important to understand that in Chinese culture, the unite of the country is a very important concept. Although during the Three Kingdom era and Qin Dynasty millions of people were killed but the result of the war is the country become united, so in Chinese culture, the emperor of Jin Dynasty(who ended the Three Kingdom era) and Qin Dynasty is are considered to be great emperor. So is to Han Dynasty, before Han Dynasty beat the Huns, they were forced to give their princess out to the Huns to keep the peace for hundreds of years. Thousands of years later after the Opium War, we finally understand that as a weak country, being invaded is unavoidable. So I think at this point, you can understand why Chinese is so determined on Taiwan issue. In 1950s when China and Soviet Union were brothers, we felt strongly about building a submarine base in China for Soviet Union. Now US airbase is surrounding China with advanced fighters and bombers, I don't think China will serve them by delicious dishes.

The J-20, keep the discussion on the J-20 ;)

For instance what are those bumps in the intakes?

[3GOCHN-443]

Yesterday's picture shows that the nose lifted up and the front wheel leave the ground during the rolling. Somebody said they saw the viewing stand is building beside the airfield suggested the first flight is coming soon

Gut instinct says hiding turbine blades, but might be something to control the airflow as well.

[Pilotasso]

The lumps are boundary layer diverters.

 

The boundary layer is basically a thin layer where air speed is lesser than the ambient air due to interaction with the aircraft surface by friction. Its characterized by higher shear stresses among air particles ( small vortexes of turbulent air causing extra drag). Ingestion of air from boundary layer is not that healthy for engine components or its functioning. They cause loss of efficiency and attack the blade and vanes by erosion. If the boundary layer is divergent, normal air flow is disturbed and can cause engine stalls. Divergent boundary layer is also what causes the plane to lose lift on the wings and stall. The boundary layer becomes visible when the aircraft performs high alpha manoeuvres and produces a thick blanket of spinning vapour all around the aircraft.

Either way, it is a divertless inlet design similar to that of the F-35.

 

That, together with the large bore engines leads me to believe that the aircraft is built for subsonic performance primarily (namely fuel economy) to achieve great range. Together with stealth, it looks like a medium range tactical bomber - basically a penetrator like the F-111, but with stealth and probably A2A capability.

[Pilotasso]

which can make it dangerous in its own way, despite not being exactly a dogfighter.

[topol-m]

I thought the idea behind the stealth fighter concept was to avoid dogfighting ;)

[GGTharos]

No, not for a fighter, topol ;)

 

Or more to the point, a fighter should be able to handle all aspects of air to air combat. To be it looks like this J-20, like the F-35, is a strike fighter of some sort with A2A self-escort capability.

 

The entire idea behind the J-20, IMHO, is to penetrate an IADS and actually blow it up.

Actualy, being stealth meeting stealth it will quickly degenerate into a close quarter fight.

[mikoyan]

The f-35 test pilot says that the f-35 can do most of the things a raptor can do with the exception of post-stall maneuvering; it would be interesting to see the f-35 display.

Seems so... And judging by first looks, it would really need those canards/TVC in any "close" A2A fight to have a chance... Size and T/W is also a big question (engine wise at least).

 

And, IMO flapping those huge canards in any way will significantly compromise its stealth characteristics... So its probably going to have different control modes, ie stealth for penetration (canards off), maneuverability for CAC... etc.

 

Also, the rear aspect IR signature is not intended to be covered/reduced in any way by the looks of it, with the method they mounted those engines unlike what we see with F22 and T50 (T50 still didnt show its IR reduction nozzles yet though but you can see IR shielding by control surfaces/tail fin)

 

However, it looks mighty cool though i must admit! :)

[26-J39]

Its quite interesting to see so many posts on this thread that question the design of the Chinese fighters. If you saw a picture of a F-22 when the F-117 was in development would you think the F-22 looked "stealthy"? Just food for thought.;) I personally don't doubt China's ability's here.

[Silent Warrior]

Hm... Let's cut to the essentials: When can I expect to put one of these in my backyard? I bet Sweden'll see another election before that baby takes off for real.

and today a guy brought a portable speed measuring radar and aimed it on the J-20, the radar didn't respond.....:lol::lol::lol:

Kudos to 3GO!

[czarnyolek]

China do want this images to leek out. Even if this plane is just a study, not a production prototype, it makes them even more powerful on a paper. Stealth fighter poses (even if it is imaginary) threat to whole region, military spending of american allies in Asia will go through the roof and probably raise F-35 program. That means more spending in USA and getting "land of free" even more addicted to PRC. Everyone wins, exept for tax payers ;)

One more thing, some people say it is more technologically advanced than PAK-FA, certnaily looks so, but dont forget, taht sukhoi prototype is probablu very far from a final product. Just a platform to test most of the patents, some of witch are still in development. Final PAK-FA will most likely vary a lot from what we see now - especially stealth wise.

Thanks for sharing that video!

 

Please, let's stay on-topic. Thank you !

Thx for the video.

 

Some of those so called "radars" are actually low end laser rangefingers. Judging by the video you posted the air was filled with moisture and there was a considerable distance to the plane, so the failure of this device probably had nothing to do with stealth.

[GGTharos]

At that distance it probably should respond, regardless of stealth. Was it because the plane was moving perfpendicular to the device? There are other issues as well, such as the distance beeing too long, and the device not being calibrated/useful for speeds that these planes operate at on the runway.
