Shenyang next gen combat aircraft thread

We can see that there are porous panels on both the top and bottom of the fuselage, and there must be a channel connecting the two panels. By this way, the low-pressure area above the fuselage can draw away the boundary layer below the fuselage at the air intake. This also proves the authenticity of this photo,as no CG artist has ever considered this detail before.

But that would be a huge amount of internal volume you will be sacrificing to make it work that way. Doesn’t seem remotely worth the cost as they could have gone with a more conventional intake design and saved themselves all that internal volume for more fuel and avionics.

If they wanted such a design, they could have gone the same route as the J20 and have the vents on the outside of the intake on the side of the plane. You get a similar result without needing to duct through your central fuselage.

Did we get a good look at the side intakes on the two air superiority drones showcased at the 9/3 parade? Wonder if they went with DSI/Caret or something more exotic like what we saw with J-XDS.

One had DSI and one had caret.

Perhaps these are avionics cooling air exits as they seem close to where avionics bay would be placed. The F35 has a real issue keeping its avionics cool and so the Chinese may have foregone dumping heat into the fuel tanks as the F35 does to go for a radiator cooling system that dumps its excess heat into the air-stream via these grills?

Are these vectoring flaps/paddles? 3D exhaust direction in a 2D/flat package?

interesting, I thought they were gonna go with fluidic TVC for yaw, but any form of yaw TVC is excellent since obviously without a tail you'll need other ways to control yaw

i wouldnt be so hasty, its far more likely they are just panels of different materials optimized for the thermal loads of that particular area of the exhaust

The most likely answer is that these models of electronic equipment have strong computing power, so they will generate heat that needs to be actively released to the outside and even worth to punching on the fuselage structure, which is enough to make people guess, isn't it?

Big kudos to J-XDS engineers for major decision to eliminate all non-stealthy protrusions to help minimize RCS and becoming trendsetter for 6th gen VLO design.

Its amazing China is the trendsetter for the 6th gen design without rear vertical stabilizers. I wonder if FCAS/GCAP/F-47 will do redesign to follow suit.

Even if this image is AI-enhanced, you can also see the "yaw paddles" in the "original" photo .

I thought so too, but then how will the jet flow be directed horizontally, if the outer parts can't move?

The inlet porous holes on the lower chin can not physically connect to outside of the intake with airduct, you can imagine it has to go all the way arround the inlet lips and there has to be enough space for a duct. And for the purpose of boundary layer suction the porous holes panel can only be located on the lower chins right before the inlets.

The outer parts are angled outwards as you can see in other images though, perhaps deliberately for flow direction as a guide vane.
