Re: JXx news.

I doubt any of those pictures (three views, CGI's, whatever) hold any real evidence of the plane. Usually there will be a couple of relatively non-PS-esque photos of the plane which we then judge to be the real thing (as happened with the J-10B).
Challenge's photo, at any rate seems to me a PS.

Though a few guys on CDF are saying similar things about the F-22 style canopy, black paint scheme, but the length's been revised to around 19m.


If that's the actual design then I have legitimate concerns about its RCS.

May I ask why, out of interest? Both of airsuperiority and challenge's pictures (though probably not reflective of the real thing) have obvious stealth shaping.

I only have a basic understanding of stealth shaping (what I could glean from wikipedia and online forums), but that design has serious planform alignment issues and having the canards not only sit on a different plane but being elevated diagonally creates extra angles that need to be taken care of when accounting for the direction of radar reflection. Unless they tested that design and shaped everything so that radar is reflected away even without the planform alignment that kinda design will pose problems for RCS.

One possible reason we don't see planform alignment from the top view is because in fact the angles of the canards are in fact in alignment with the main wing, only in that elevated position, so the canard shape itself is a different shape but forms the same angle in that tilt. Still, I don't know if that would work.

Ah right. Pushing this topic a little, I think the canards on that picture is on the same plane, and is aligned with the main wing (leading edge and triangular trailing edge area which kind of bends into the engine nozzles).
The only area I see which may not be too stealthy is the round, JF-17 style LEX.

Regardless, it's only a random three view anyway. Not even a well drawn one : /

Re: New Generation Fighter

There has not been any valid photo coming out thus fast and dont expect any to come out for at least a year, I would guess it probably would not come out until 2012. Until then, we will see a continuous stream of cg and ps photos. Even if someone gets a photo, it would be blocked from coming out.

Re: New Generation Fighter

I completely agree with You - even if I hope we are wrong !! - but since the CAC facility is so much "public" I can't see how they would make high speed taxy-tests or even a first flight without being noticed. The only way ... at night; and I can't think of that.

In comparison to the J-10, there was no real internet community ... no BLOGs aor such active spotters in China around ... and now, even the J-10B was noticed before it was "semi-officially" unveiled.

As such I have strong hopes that with the XXJ or J-20 ... we will see it much earlier.

Flight Global is saying that the JXX will be an 'F-22' look a like, but given how uncharacteristically shoddy this entire piece is written, I'm hardly convinced about the validity of such a statement.
