A utility patent that might be of some interest or at least interesting to look at. The illustration is obviously based on a J-20 fuselage, although this by itself doesn't mean the concept or idea necessarily has a connection with J-20 or has to be confined to J-20. Note the movable surfaces have been greatly modified to allow for flexible aerodynamic configurations. The link below contains a full English translation.
Abstract: The invention proposes a kind of variant invisible plane and its changing method and applications.The aircraft is designed by stealthy requirement, moves canard and two deflectable formula slab tails entirely using lifting body strake wing allosteric type aerodynamic arrangement scheme, including two deployable and collapsibles. Deployable and collapsible canard takes in fuselage when aircraft cruises or high speed is flat winged, to reduce radar cross section, improves stealth. Deflectable formula slab tail is then deflectable to different angle under different flight state, thus as V-arrangement tail, horizontal tail or abdomeinal fin.The transformation of the aircraft aerodynamic arrangement, including canard configuration, anury formula layout and three-surface configuration are realized with this.The switching of three kinds of aerodynamic arrangements can combine the advantage of this three, preferably meet the requirement under each flight profile, mission profile and state of flight to air maneuver and stealth.The variant aircraft can be used as a kind of high lift-drag ratio, high maneuverability, the good someone of new generation of stealth and unmanned air fighting platform, for executing air superiority combat duty.

Nvm i guess it's like a tomcat vanes sorta
might as well just design a new jet with all those changes

Split rudder like the B-2
Based on the concept sketches the aerofoil seemingly forms an anhedral shape, which enhances directional stability
Awesome analysis. I have become a fan of that guy. He has lots of other cool videos as well.
Check out this video of him comparing J-20 with other 5th gen planes.

Will that be enough for a fighter? TVC being necessary for something like that J-20 is a given. Interesting there are some leaked concept drawings. Who's applying for these patents? If it's a government/AVIC project what's the point of applying for patents?

There might be more to this patent than you think.
A CAC employee was recently commended for his hard work on a "special type of aircraft wing". Some people speculate that this involves foldable vertical slabs/canards.
So people on that thread at cjdby are guessing that these variable geometry things are to optimise stealth. When cruising and needing to penetrate heavily monitored airspace you retract the canards and place the tail horizontal for optimum stealth (and there's probably some aerodynamic advantages, ala F-14's swing wings). When in combat and you need agility those things are extended.
Nice, it's got a whole "lock S-foils in attack position" thing going on.

Please don't post content from that channel, because it doesn't meet SDF's standards. He's simply not a credible commentator. Also, comparison threads or posts are forbidden by SDF rules.
