I was right not enough tail, so they added the underside strakes a-la the Lear 45 Series and the add on Strakes fot the Beech V-Tail Bonanza via an STC. They help at high alpha or so I read.
The Planform does not look like what was discussed here the other day a-la F101 Voodo., just tapered.
Notice the little but subtle Leading Edge Extension ( LEX ) from the wing to the Canard, it looks like a hard chine, again to create vortices's at high alpha.
From the rear end the lower strakes and pod it sits on is to busy, my guess not good for RCS.
Also notice the wing, a great deal of aero or geometric washout near the tip. I believe the Mirage's and the Concord did this with their Delta platforms, so this maybe more of a delta augmented by a canard and Ruddervators...
Then again, fully flying rudders can be smaller than combo rudder/vertical stablizer. But they were huge on the FX-23 as they were for pitch and yaw. The F117’s were pretty good sized and they were for Yaw only or so we were told....
But remember that this is not an operational fighter, it is a technology demonstrator.
I have read elsewhere that the lower strakes will not be on the production aircraft. They also need to figure out a way to hinge the flaps without those large hinge fairings under the wing. Makes it look like the wing of a 737.
My guess is the canard is a design compromise to give more pitch control at high angles of attack. This tells me they haven't figured out fly-by-wire quite yet. The canard also won't help the RCS a bit.
The Chinese will learn early on in this aircraft's first engagement with a foe that just because it looks like a stealth airplane doesn't mean it is a stealth airplane. There's a lot more to radar stealth than just shape....
I was thinking that with all the “add-ons” you mentioned that this thing will be about as stealthy as my motor home.
And considering the Chinese build quality I have seen in other vehicles(look good, but fall apart in 6 months) I would not want to fly it. The real rigors of combat will render it useless after a few missions.
