J-20... The New Generation Fighter III

In other words the FBW thinks that the movements of the plane due to uneveness of the runway as the plane's movements in flight and tries to correct it using the control surfaces?

youtube version of the flight video, embedded for your convenience:

If you only have one chute, it might deviate and catches jet exhaust from one of the two engines predominantly, making it dangerous for the plane during landing.

The chutes are deployed after touch down, so there is no danger. But PLAAF will use only one type of chute so the heavier aircraft will need two chutes.

If the FBW were to actually counteract the undulating movement, instead of letting it be, the aerodynamic drag would be increased considerably. I saw the wild flipping of the control surfaces in only one of the many videos of J-20 taking off and I presumed it was part of the scheduled testings in the particular flight test.

Very nice !!! Did You notice at 0:30/0:31 the PU/JFS exhaust flame !
Besides that ... what (number ?) flight was it ???

yep saw that, can't wait to see more, this video is good, but we need more and better, cmon Chengdu fence climbers
you people with SLRs, stop hiding the photos!

45th flight. The 46th is going to start today, according to J-20 watchers.

I want more pictures and videos of some aerial maneuvers!

New video on the 13th!

Those are REALLY thick accents.

Is that differential deflection I see?

This PS would be an interesting look.

Just another 90 degrees and I can make my t-shirt.

From GT over at CDF.

^J-20's sexiest angle so far

can someone explain if the upper body surface right beside the canards and above the intakes generates lift? part of the overall lift or itself a lift device?

Great shot!

Now, what's the idea of the many small white patches on the wings and other places?
