J-20 5th Gen Fighter Thread IV (Closed to posting)

[latenlazy]

still 2012 !!??

Hard to tell if that last digit is a 2 or a 3.

EDIT: A second look suggests it might be a 1.

Here's an interesting article to read. It talks both about the current carrier project and a possible navalise J-20. I didn't know where to put it, so I put it here.

China is likely to complete the construction of its second and third aircraft carriers with the ability to carry J-20 fifth-generation stealth fighters, although a carrier-friendly model may need to be designed first.

China’s domestic aircraft carriers currently designated ‘Type 001A’ will look very similar to the Liaoning, the country’s first aircraft carrier bought from Ukraine and refitted. They are most likely to be equipped with a ski-jump ramp. The displacement of each vessel is expected to be around 70,000 tons, similar to the Liaoning’s maximum displacement of 67,000 tons. China Shipbuilding Industry Corporation has already received contracts for the construction of two Type 001A carriers, at a projected cost of 50 billion Yuan (about US$9 billion.) Work on the second aircraft carrier has already started at the Dalian shipyard. This carrier, the first to be designed and built in China, is expected to be commissioned by 2020.

The PLA Navy is planning to form two composite air hangar decks, with 50 fighters for each carrier (compared to the Liaoning’s single deck hanger storing 30 J-15 fighter jets). However, the design of the Chengdu J-20 is currently too large to be deployed aboard the Liaoning, according to the report. Domestic carrier versions will have to be larger to accommodate them, putting them at an estimated 80,000 tons. Furthermore, they may use a steam catapult or electromagnetic aircraft launch system.

The current J-20 prototype is not designed for carrier operations, and is not suited to take off or land on a carrier. The length of the first domestically built aircraft carrier may be be longer than the Liaoning by an estimated 20 meters but a new version of the J-20 will have to be redesigned into a more compact size, similar to the current J-15.

Eventually, China’s future carrier air wing may come equipped with 25 stealthy, 5th generation fighters such as the navalized J-20s, which will become the carriers’ first line strike fighter, capable of attacking denied or contested enemy airspace or naval forces, along with 25 J-15B 4th generation fighters, which will provide second line attack, self defense, electronic attack and refuelling support.

Once completed, further carriers will greatly increase China’s force projection capability into the Western Pacific and Indian oceans.

This article looks like empty speculation.

...

How often again do we have to discuss this ???

This article looks like empty speculation.

Not only that, it sounds like the author doesn't know much about fighters or aircraft carriers at all. First he says that it will be similar to Liaoning, 70,000 tons with ski jump, but then talks about it being increased to 80,000 tons and equipped with EMALS or steam catapult, making it a beast of a whole other league. And that's not to mention that he thinks J-20 is significantly larger than J-15. He's probably just writing cus he had to churn out an article for his job...

Some new photos said were taken during this national holiday (flying with a J-10B)

Any news - or even at least a rumor - regarding '2013' or that mysterious second airframe we saw in the hangar while 2012 was making its taxi tests in July ??

Something I've been meaning to do for a while now -- a chart that depicts the J-20's EODAS style ports all around the aircraft.

We haven't had that many clear pictures of the aft of J-20's cockpit, but the few clear pictures we do have seem to suggest there is an aperture there -- akin to F-35. Virtually ever port on J-20 is in a similar position to F-35.

First is an F-35 pic I found on the net a while ago, and the similar one for J-20 I made. Note, on the J-20 three view I've highlighted a few ports more than once. Both planes have the same total number of ports (6)

A few caveats:
This doesn't necessarily reflect that J-20's EO surveillance system is similar in capability to F-35, specifically in the 360 degree, helmet view way. F-22 also has multiple Missile Launch Detector apertures (which EODAS was based on) arranged around the aircraft, and it serves as an advanced MAWS rather than as a comprehensive pilot surveillance, tracking, and display tool like EODAS. However, the fact that J-20 has its own EO ports arranged in what is obviously a 360 bubble, makes me think that it is more than a MAWS and it does have a role similar to EODAS. For instance, I do not believe F-22 has an MLD aperture facing directly forwards on the nose like J-20 and F-35 do.
Also, it's worth cautioning that just because J-20's ports are arranged similarly to F-35, doesn't necessarily reflect any espionage or copying of the actual technology. There are only so many ways you can arrange such ports to form a 360 bubble around your aircraft, and form will naturally follow function. (That is likely a similar reason for why J-20's undernose IRST/EOTS is so similar to F-35's in both position and shape)

Outstanding post bltizo, and I agree with everything you have observed, and fully concur with each point, no doubt the J-20 has taken advantage of all the available technology, and I have no doubt that the J-20 is more advanced than the F-22 in these areas, but that both probably trail the F-35 in situational awareness.

I'm pretty sure the little frontal trapezoid is a forward facing EO aperture. I believe the F-22 has full 360 degree IR coverage, but only for missile warning.

As a side note, the PAK FA's 101KS-U also seems to have full 360 degree IR coverage.
