Calling for a ban to stop the endless posting of dribble.
Lets get back to the topic please
Yep! I second the motion! lets get back on topic, J-20 debuted at Zuhai, be happy!! or don't!!! but lets get back to the J-20, and can this "pre-school" tattling, bickering, it has no place on SDF.
Intelligent, thoughted, statement of a position or your concerns, fine!
I can only second the last two post !!!
STOP, STOP right that moment.
All arguments pro & contra were mentioned and not a single additional post will either persuade the "J-20 is a lame thing"-fraction guys nor the other ones.
As such this edless, senseless and most of all stupid back and forth ends now, right now.
Otherwise I will close the thread until some new images appear.
End of debate.

I'm perfectly fine with the articles Blackstone posts here. Don't you guys ever read through old threads and reminisce? Reading all those articles from the past about how the J-20 is vaporware, then PS, then mock up, then one off TD, etc. etc. really puts a smile on my face. What will I chuckle about in a few years when I look back at this thread if we don't have quotes from Andrew Ericsson on it?
BTW, having to skip all the pages of retarded arguments with mig-29 in those old threads was a bummer, I imagine it'll be the same in a few years when I look back at 2016 and having to skip the rants from his latest incarnation.

The dogs don't want to give up their teeth, next question????
I'm sure they could contract out the Russians to have serrated nozzles for these Al-31 variant engines if they really wanted to but I imagine that would introduce extra cost and additional time.
Superficially serrated round nozzles might look a little bit more "stealthy" than round nozzles but I doubt there is much of a big difference.

Finally, critics like to point at J-20's engine nozzles and proclaim "J-20 doesn't have all aspect stealth", while praising F-22 nozzles as the de-facto stealth design. In reality, the F-22 nozzles don't make the plane stealthy from the rear. Let's look at an illustration. Here we have a picture of F-22 on afterburners:
We know the afterburners are on because we can see the flame. The flame is held by flame holders, so what we are looking at is the flame holders themselves. One important thing to know about them is that they are concave, so as to shield the flame from very fast moving exhaust. Here, one can see the flame holders in the nozzle of a F-22, with about sixteen of them in each engine:
Needless to say, the requirement to hold the flame precludes the assembly from being stealthy. Then, there are the turbines sitting in front of the flame holders, with all sort of voids to bounce radar signal in an uncontrollable fashion. The fan at the front of the engine has the same problem, but engineers meticulously designed the intake duct so as to hide the engine from view, as illustrated:
It is hard to appreciate the design, and the amount of work in coming up with such design, until one looks at the intake duct before its installation:
So, the notion that F-22 styled nozzles give the aircraft all-aspect stealth is flawed, simply because hiding the engine from view clearly involves way more effort than just making the exhaust rectangular or adding sawtooth to the exhaust petals.
