J-20... The New Generation Fighter III

I think they will need 4-5 prototypes for all testing. That will take around 5 years. so 2013-2014 is still "highly impossible".

Even the the 2nd prototype may still retain round nozzle. Very high chances, it is WS-15 debuting.

Better wait to see it before implying that.

IMHO nozzles and engines are secondary respect to radar presence on the 2° protoype, of course would be fantastic if China were already testing such advanced engines, but my impression is that China has more a problem of "quantiy of the quality" than pure quality so they would be better working hard to make j20 operative as soon es possible. For example if china will produce from now to 2020-2025 tons of j10b complemented by a rising number fo j20 China would finally became an airforce superpower. On the other hand if j10b is produced in limited quantities and j20 will be mass-produced far after 2015 they will be weaker.
For now, it is great if this is the second prototype, and very nice if it has a radar on it.

I don't understand what do you mean by this sentence.. It's sound contradicting. If you follow PLAAF doctrine enough.

Here's a slightly larger one ...

Ah. If I'm wrong, then I'm happy to be so, lol. I want to see some bigger changes in the 2nd prototype, even though I know that's unlikely.

I obviously don't see anything other than that though.

That's the old one lol. The new one is on top.

I no longer remember, were there one or two prototypes of J-20, before and after the maiden flight?

Like I said, glad to be wrong in this case. .

I believed he meant mass production of high tech stuff quickly and readily available for either export or immediate defense purposes. I hope I'm not confusing you.

This picture is from the time before J-20's first flight. I'm posting this here for lulz. We can see the amount of work that people are willing to put in in their desperation to dismiss the J-20:

[QUOTE=Deino;183502]... and the ventral fins are missing !

They better not be, Dr. Song will go down to Chengdu and kick some butt, and if he calls me, I'll go with him! Leave my vertical stabs and ventral fins alone.[COLOR="Silver"

Lion I mean that is better for me a j20 as it is operative in 2015 instead of a super j20 with all stuff, nozzles , etc in 2020

went to indian forum, there is a guy doing comparsion on stealth characteristics of j20. now i'm not a stealth expert so, if anyone want to verify/aruge true or not. go for it. post #1488 & #1491

First set of pictures: F-22 doesn't have these sawtooth on the control surfaces either. Sawtooth isn't needed when proper edge alignment has already been used on the J-20. That's not to say it isn't an interesting solution. Also, read the statement on the F-22's picture, and you will see that he still thinks the trailing edge of the J-20 is "flat". Obviously, he is ignorant to the top-view of J-20.

Second set of pictures: the structure used to hide the gap on the J-20 is right in the picture. It is more elegant compared to Rafale's (and J-10's) solution because it is not an after-thought.

Third set of pictures: how does he see RAM coating and the material being used with naked eyes? What an idiot.

Forth set of pictures: he just highlighted the break in continuity in the left picture. In that same picture, we also see the top-view of F-22 showing the exact same break.

Next five pictures: I have seen this argument before. The problem with this argument is that round edge also exists on F-22, F-35 and PAKFA as the chine of the nose.

Next four pictures: Here is a top-view diagram for all three stealth aircraft. One less edge represents one less direction to reflect radar to.

please don't bring those kind of stuffs here

leave them where they belong

on topic of the 2003, we'll see it when we see it
