J-20... The New Generation Fighter II

They just could be divets. The DSI bump on the FC-1/JF-17 has them. The divets are like on a golf ball and makes it travel further. Air travels smoother over the curvature covered in divets.

Golf balls have divets to cause the air flowing over them to go turbulent. This increases the pressure on the after side of the ball. This is not relevant for the flow over the DSI bump.

That's self-explanatory, don't you think?

Although I am pretty sure F-16 got it too, but I guess the tech-gap (between 70's F-16 and THE 4TH GEN) is somewhat also self-explanatory.

F-16 doesn't have a true one piece canopy. It opens from the rear instead of from the front. The wire is at the rear.

The Americans apparently didn't think so since none of the JSF prototypes had things like MAWS windows or stealthy IRST installed. Those only started appearing on pre-production airframes.

1. Just because US is doing things one way does not mean China has to do it the same way.
2. F-35 is not the latest of several stealth aircraft program for US, while J-20 is close to the first, if it's not the first, stealth aircraft developed in China. Conceivably, China would like more time to fix any issues found, as early as possible.
3. China may want to compress the development cycle to close the capability cap. Unlike US, manpower seems to be less of a concern -- more things are done in parallel to compress the development time, v.s. more things are done in sequential way to lessen the peak manpower demand.

I don't think this has been posted. Huitong has updated the J-20 entry.

"Two samll dark diamond shaped windows can be seen on both sides of the nose, which could house certain EO sensors, such as MAWS and/or IRST. Two additional windows are seen underneath the rear fuselage, plus two more on top of the forward fuselage above the canard wings, suggesting a distributed situational awareness system similar to the EODAS onboard American F-35 was installed provding a full 360° coverage. "

On May 5 PM 15:30, Chinese Air Force J-20 Stealth Fighter makes its third test flight in Chengdu. The flight lasts about 55 minutes and the highlight is the aircraft front and main landing gears have been folded in the fus(e)lage.

I do wonder about the reliability of china defense mashup... it seems to occasionally come up with gems but most of the time isn't very useful. We haven't heard anything from the typical sources, but mashup did come up with a few pictures supporting the statement...
Right now I'm a bit dubious on whether these are real, until the big guns on CDF or huitong say otherwise.

Looks like it's real. I don't think you can PS multiple angles so well.
AWESOME

This is significant, Project 817 is going to its next stage.

In this case, very soon Seigecrossbow can change his profile photo for a real one.

If the WS-15 can be developed within these 2 years, we may see J-20 operational deployment with TVC by 2015 the earliest. I doubt it can be earlier than 2014 as that would be too pushing it. And of course I'm just rambling so don't put me on the crucifix.
