J20 Stealth Fighter

[niceguy2011]

Similarities by Coincidence or More than Mere Coincidence?

I think it's the latter, the J-20 is a mere modification of the Mig 1.44.

Simply,could Russian make an one piece wind shield ?

Why isn't the J-20 canopy gold tinted? That is more important than a bubble canopy.

China's First Master Designer

July 5, 2011: After years of trying to keep it a secret, China has confirmed that one of their aircraft engineers, Yang Wei, is actually one of those extraordinary designers who produces one successful design after another. Born in 1963, he graduated from college at age 19 and finished graduate school three years later. He soon went to work at the Chengdu Aircraft Design Institute, and a decade later was appointed director. So far, he has designed a working fly-by-wire system, as well as the JF-17, J-10B and J-20. He did not design the original J-10, but did design the most successful version, the J-10B, and provided important upgrades for other J-10 models. The new J-20 (a stealth design that is still in development) is less of a surprise now that it's known the Chinese have a genuine ace designer working on it.
Ace aircraft designers are rare, and those that do show up tend to create a number of exceptional designs during a few decades (or much less, if there's a war going on). For example, Russian designer Mikhail Simonov recently died (at age 81). He was responsible for the Su-24 bomber, the Su-25 ground attack plane and the Su-27 fighter. Starting during World War II, for example, one American designer (who was trained in Germany), Edgar Schmued, designed the P-51, followed by the F-86 and F-100 after the war. In Germany, Willie Messerschmitt designed the Me-109, Me-110 and the first jet fighter (Me-262) plus several others during World War II, and a few after the war.

In China, Yang Wei appears to be the first designer in this tradition. He had nothing to do with the original J-10, the first modern jet fighter designed and built in China. That appears to explain the many problems this aircraft has had. The J-10 was an attempt to create a modern fighter-bomber that could compete with foreign designs. The experiment was not completely successful. Work on the J-10 began over twenty years ago, in an attempt to develop an aircraft that would be comparable to the Russian MiG-29s and Su-27s, and the American F-16. But the first prototype did not fly until 1998. There were continued problems, and it wasn't until 2000 that the basic design flaws were fixed. By 2002, nine prototypes had been built, and flight testing was going forward to find, and fix, hundreds of smaller flaws. It was a great learning experience for Chinese engineers, but it was becoming apparent that the J-10 was not going to be competitive with the Su-27s/30s China was buying from Russia. The J-10 looks something like the American F-16, and weighs about the same (19 tons). Like the F-16, and unlike the Su-27, the J-10 has only one engine. Yang Wei improved the J-10 considerably with his J-10B version.

But it was the JF-17 (also known as FC-1) that made Yang Mei's reputation. The JF-17 was developed by China in cooperation with Pakistan, which originally only wanted to buy 150 of them. All this came about because Pakistan could not get modern fighters from anyone else, and turned to China. At the time, China had nothing comparable to the early model F-16s Pakistan already had. The 13 ton JF-17 is meant to be a low cost alternative to the American F-16. The JF-17 is considered the equal to earlier versions of the F-16, but only 80 percent as effective as more recent F16 models. The JF-17 design is based on a cancelled Russian project, the MiG-33. Originally, Pakistan wanted Western electronics in the JF-17, but because of the risk of Chinese technology theft, and pressure from the United States (who did not want China to steal more Western aviation electronics), the JF-17 uses Chinese and Pakistani electronics.

The JF-17 can carry 3.6 tons of weapons and uses radar guided and heat seeking missiles. It has max speed of nearly 2,000 kilometers an hour, an operating range of 1,300 kilometers and a max altitude of nearly 18,000 meters (55,000 feet). China has not yet decided on whether it will use the FC-1/JF-17 itself. This is apparently because China believes its own J-10 and J-11 (a license built Russian Su-27) are adequate for their needs. The J-10, like the JF-17, did not work out as well as was hoped, but that's another matter.Warplanes: China's First Master Designer

No, Mig didn't help developed it, in fact Mig made it, obviously it's a Mig 1.44 in plastic decorations.

Wrong, it is just a toy made in GuangDong.

 

[mileycyruslove]

Guess why didn't chinese engineers make a copy of LCA 'the indigenioness'? Hint: "she's holding back she's hiding", lol

 

[ace009]

Actually, the J-20 is indeed a version of the Mig 1.44 Technology demonstrator - probably modified for Chinese avionics, advanced stealth features (newer RAM coatings etc) etc.

Here are the picture comparisons of the two ...

As you can see, both aircraft have delta-canard shape, very unusual for 5th generation fighters. The front canard is liable to increase the frontal RCS of the aircraft.

Because the Mig 1.44 wasn't designed with stealth in mind.

 

[ace009]

Because the Mig 1.44 wasn't designed with stealth in mind.

So, how are the Chinese engineers taking care of RCS of the front canards in the J-20? in my mind, any aerodynamic gains due to frontal canards is more than negated by the loss of stealth from the canards - more so when the canards are deployed in flight to increase/ decrease lift.

 

[Armand2REP]

It's a MiG 1.44 with an F-22 copied nose. There are plenty of reports MiG cooperated with China and the evidence is obvious. It is going to have the same problems as the 1.44, if not more.

 

[asianobserve]

Don't forget that the J-20's intake design has more than a passing resemblance to that of the F35. The canopy is definitely F22.

So basically, what's emerging is that the J-20's basic airframe is Mig 1.44 (obviously courtesy of the Mikoyan Bureau) with bits of F22 and F35 on the nose, intakes and canopy (courtesy of Chinese espionage).

Aircraft 1035 is the first J-10 to be seen with the Chinese WS-10 engine since the early prototypes. The engine can be distinguished from the Russian AL-31FN by the profile of the nozzle.

The design institute at Chengdu flew a J-10B development aircraft fitted with the indigenous Shenyang Liming WS-10A Taihang engine at the end of July. All previous J-10s, apart from the first few prototypes, have flown with the Russian AL-31FN engine. The aircraft with the homegrown engine is coded "1035" and is presumably the fifth J-10B prototype, although that number may include a ground-test article.
The WS-10 has always been the intended powerplant for the J-10, but problems with its development led to an early switch to the Russian powerplant. The J-10B flight trials suggest that the engine has matured enough to now be considered for a single-engine application. Clearance of the Taihang engine would make the J-10 an "all-Chinese" aircraft, available for export without any external restrictions.
Meanwhile, an uncorroborated report of comments attributed to a high-ranking official at the Chengdu facility stated that the J-10B is about to enter production for the Chinese air force, and that the first unit of approximately 10 aircraft (with AL-31FN engines) could be delivered by year-end.
According to this same report, production of the J-10B, which features active electronically scanned array (AESA) radar and a diverterless supersonic intake, would proceed alongside that of the J-10A for some time. Chengdu Flies Chinese-powered J-10 Fighter: AINonline

parkistan will buy lots of them.

 

[LETHALFORCE]

parkistan will buy lots of them.

Better for us they buy a 3rd generation plane then world class Western Planes.

J-10B will be a 4.5th gen fighter mate. What're you talking about?

parkistan will buy lots of them.

What's the use? Their worst enemy is sitting right inside their country. But yeah, they don't hesitate to bomb their own people to smithereens as we saw in Balochistan and NWFP where Pakistani F-16 jets conducted dozens of sorties against small villages of unrelenting Pushtuns who did nothing.

Now J-10Bs would be used.

BTW they can't buy "lots of them". The only legal money they paid for weapons was for the first 36 J-10s in 2008. After that, whatever they're buying from you including the FC-1, they are doing it on soft loans by Beijing. So basically, they're buying weapons on loan.

Somehow, I really like the design of J-10B. It looks menacing and more like a single engine Typhoon. Any idea when you guys adding AESA radar to it?

 

[asianobserve]

It's rumored to already have ASEA radar.

 

[nrj]

And what are the rumored specifications of the same?

 

[asianobserve]

I don't know if we can exactly determine the radar specs from these photos:
