Man 2001 looks really beat up.

She's a working woman now latenlazy, all the make-up and nail-polish and hairspray gets blown off, you will also note that this is the initial roll-in to the bank as the right aileron is deflected downward a great deal and the left aileron deflected upward slightly, so this is a fairly vigorous approx 2-3 g turn. For those who are not pilots, an old aeronautical rule of thumb is that in a 60 degree bank you are pulling 2gs, and that is one of those "universal truths of aerodynamics".

It is nice to see the princess again in her true element, but this picture reminds us that if indeed 2001 is indeed being operated in a fifth gen flight regime, it is very hard on airframes and pilots. The fanboy non-sense that because we lost another F-22 means the J-20 is propelled into the top slot indicates a real lack of understanding of just what a fifth gen fighter does in her everyday life. The F-22 first flew in 1995, the loss of four airframes and two far more prescious lives is indicative of just what a robust and safe airplane the F-22 is in actuallity. These aircraft are pushed to the limit every day, these fanboy comments about how dangerous or unsafe the F-22 is, give light to the lack of "light" in the individual posters awareness. The fact that the F-22 was lost on recovery to the airfield reminds us that "flying" is dangerous, and you don't breath easy till shes on the ground and in the chocks.

So go ahead, make all these bold statements that are derogatory to the F-22, and lift up your glorious J-20 and J-31, you have three airworthy airframes, 1, 2, 3, meanwhile the F-22s are out there every day and night defending freedom, wherever it may be challenged. In the meantime, I'll thank my God that our little sister, flung her fearless operator to safety as she paid the ultimate price. Now that is true nobility, and worthy of a little respect!

So gentlemen, educate yourselves a little before you go off on that little internet chicken dance, flapping your wings and such! and remember, wifey just asked why I was smiling, she said you always smile when you're typing, and yes I am smiling, but remember, no one on here has bragged on and complimented the J-20 or Dr. Song for his vision as I have, but, as poor old NIKE X used to remind us all, this is a dangerous business. Y' all have a nice day, I'm going to church, and my Sunday School lesson mentioned Dr. Bill Wallace, a man who loved the Chinese People enough to pay the ultimate price! Now that is true nobility. Have a great day guys, and remember, somebody in America loves you, in fact lots of somebody's!

What's more interesting is the question asked in one comment: What's the plane doing with the two trailing edge flaps pointing at different directions (one up and one down)?

And so far, what has attracted my attention often is that the canards are most of the time in angles that push the nose down. Here I ask again: Does this mean that the airframe, especially the nose section, generates great amount of lift such that, when the aircraft's not turning, the canards have to be used to balance out this lifting force?

An emphatic YES to your last question, and to your first question they are FLAPPERONS not just flaps, and they are in fact the primary roll control of the J-20, left flaperon deflected upward, [decreasing lift], right flaperon deflected downward, [increasing lift]. Flapperon is the proper name for the combination aileron/flap on the trailing out board main wing on the delta, Elavons are the proper name of the combination elevator/flaps on the inboard trailing edge of the main wing. That was indeed the first thing I noticed about this picture player, and I am typing this after posting about it before I read your post. Good Catch! AFB

Thanks, Brat! It's obvious that combination of the two flapperons will make the plane roll, say 90 degrees, into banking. And once the plane's banking/turning and to keep it turning, both flapperons will then deflect upward, won't they?

Another F22 crashed, that's why I always say if they can deploy J20 by 2016, it has a good chance of becoming the first operational stealth fighter in the world.

Don't really understand the sentence. The F-22 is already an operational stealth fighter and in fact the only one.

Surface patterns on both wings are different. Why?

Come on peoples, it's clear as day: the "patern" you see are strain gauges. Light play tricks in certain conditions, i'm sure pics from above of 2001 from different angle/ light conditions will show it's not "beaten up". It's less than 2 years old and has in the region of at least 100 sorties (i suspect), how can it be "beaten up"?

Anyway, so any insider news about the real 2003? Thanks.

Yes they will Player, and thats one of the many reasons I say that the J-20 is such a smart airplane, as Dr. Song alluded to the FBW is quite an engineering achievement in and of itself. Thats probably one of the reasons I have stayed away from aft mounted deltas, because the aerodynamics are quite complex and intertwined, thanks to the engineer I finally understood that downward deflection of those canards when the aircraft was obviously displaying a positive angle of attack, but forward fuselage lift solved the mystery, now I imagine as the aircraft passes through Mach 1 and would experience Mach Tuck, that all these forces come into a harmonious balance? Thats why I wish I could be a little mouse at Chegdu, I just love all this stuff! Have a great day guys, AFB

The same reason, why the vertical stabilizers are not showing in the same direction?

The canted vertical stabilizers function both as elevators and rudders. When they move in different direction, they function like elevators. When they move in the same direction, they function as rudders.

It's interesting reading articles following the emergence of the J-31 stating that making a stealth fighter stealthy goes beyond just stealth shaping which includes RAM paint. I seem to recall critics of Chinese fanboys when the J-20 came out downplaying RAM paint saying if it was that effective as the fanboys were arguing, then you can significantly reduce the radar signature of any aircraft by RAM painting. I'm an admitted amateur but it's sort of odd to me that supposed professionals are now arguing what Chinese fanboys were criticzed for. I assume they're just not talking about RAM paint either. So what else? Isn't electronic means detectable? You might not know exactly where it's at but you have an idea to send interceptors at least.
