Aerodynamic question.

Root of J-20 canards is on the same position to main wings while canards on Rafale is above the wings. Is this why the Chinese have no choice but to angle the canard above the wings to generate vortex to the same effect?

no true. J-31 has much small engines whereas f-23, 22 have the same engines. J-20 and j-20, su-27 and mig29, f15 and f16, these are high and low fighters

Such an armament was typical for interceptor designs from the 1950s: MiG-21, Mirage III, Su-9/11/15.

su-11 and 15 were armed with radar homing missiles and maybe 2 other IR missiles. Even smaller Mirage and Mig-21 (later version) were armed with SarH missiles. For a size fighter such as Lightning, it only carried 2 IR missiles. Badly placed landing gears leave no room for under wings pylons. Not much internal fuel. Internal space is mostly occupied by air ducts to the engines because of top and bottom arrangement. The supercruise, fast climbing Lightning was eventually replaced by f-4 and Tornado with lower climbing rate.

I rather have Xf8u-3, Phantom and F-106, designed from the 1950s.

From side and bottom view, YF-23 is very ugly. YF-22 is ugly, F-22 is most pretty. x-32 is the most ugliest. J-20 looked too long from the side view, but the front is okay.

[QUOTE=TomcatViP;2049556]Ok but he didn’t talk about carrier. Pickets ship, AEGIS, tankers, AWACS doesn’t need a huge warhead. As he said, just imagine what can achieve a “simple” Phoenix type missile with some PifPaf tech, KEV etc…

F-22, Pak Fa, mig-31, F-14 all can do these, I guess they are designed for anti CVBG mission.

Here is my thought, I got not thing to backup my BS.

New new PL-15 is clearly designed for close packing because its wings are cropped. their body dimension is roughly equal to PL-10. If the Chinese originally think they only need 4 missiles in the main bays. They can fit 4 PL-10s in there without any problem. It doesn’t make any sense for them do design another missile, PL-15 with similar size.
If they want to fit 4 missiles in the first place, they would make it more efficient by making PL-15 a little bigger because, there are clearly more room left after fitting 4 PL-15. Wasting alot of space.
I could be wrong. I think the chinese will make the hardpoints more flexible where they can move the harpoints attachments left or right, forward and backward for air to air and air to ground missiles.

There is no way to pack 6 missiles unless they shift the middle pylon hardpoint forward like in f-22 to clear the fins, even for a smaller missile like Amraam.

they can rotate the middle missile 45 deg with the one of the fins recessed into the pylon, but then middle missile have to fire first because it overlaps the top 2 missiles.
