Forget it; Paralay is a nice guy, but totally obsessed by Russia's superiority and so he miscalculated almost everything! The most funny detail, according to him, it uses three RD-33! ;)

Why would anyone use three RD-33 when two WS-10 would suffice.... we mock the nafo idiots all the time but this russian guy is something else, the thing that impress me the most is the amount of effort he put into it

What can I say man... There are always retards who's pretending to be geniuses:


Like, did he not see those massive internal weapons bay (IWB) and the landing gear bays in the way? If those air intakes are straight like a pencil, those IWB and landing gear bays must've been located in The Backrooms that can only be accessed using some kind of wormhole technology.

IMO, what define fighter generation is base on kill chain. New kill chain=new generation.
J-36 represents the kill chain that vastly out range, out last, out number, out survive the existing one; whether on it's own right or as a node for CCA.
B-21 lack of speed put it out of J-36's kinematic league which compromise it's survivability and weapon range on Air to Air target.
So I don't think B-21 is 6th gen.

Chinese libs usually end up the way they are because they can’t pass primary school geometry.

Another part everyone's ignoring, which I find funny, is how the f* is B-21 designed with no consideration for air to air suppose to detect J-36 with 6th gen stealth, lol

Assume you meant the split ailerons, they're to produce yaw torque to enhance yaw stability since the plane don't have vertical stabilizer. They open up to create drag, so unequal drag (one side open one side close) creates torque in yaw axis.

If you mean why they split the split-ailerons in two sections, I can make a guess:

Notice the angle of the split ailerons on B-2 is obtuse to the planes axis, so that when the split ailerons are deployed they enhanced stability in the yaw axis (slight perturbation in yaw result in larger frontal area on one side and smaller on the other side, creates a torque to correct the plane)

Contrary to B-2, J-36's diamond form trailing edges are at acute angle to the plane axis, if they arrange split ailerons parallel to trailing edge like B-2 does it will cause adverse effect to yaw stability. Hence you can see how the J-36's hinges of split ailerons are not parallel to trailing edges and instead at an angle, at this point you can easily tell why they split it in two sections because otherwise there isn't enough space for it.

Anyway, this is my best guess.
I also speculate that the reason why the split is at an angle rather than parallel is because the top aileron is deflecting over-body vortical flow, which pinches the pressure distribution over the wings laterally, while the bottom provides yaw stability like ventral fins. If my guess is right this arrangement gives the flying wing a good degree of controllable instability.

Wonder if 6th gen can launch hypersonic munitions at speed that their engine can get straight to work without needing boosters.
This is really old way of thinking.

the power of j-36 will not come from itself but also from UCAV that you package around it.

think about something like MD22, both it and J-36 will have 3000 km combat radius. Anything MD-22 drops will be hypersonic just due to its momentum alone.

Mach 2.5+ with high altitude flying means long range missions
No, mach2.5+ won’t be the most efficient cruising speed.

higher speed allows J36 to get to battlefield faster. That carries signifi
Just by eyeballing the J-36, it should have 50% more range than the J-20 because of the doubling of the fuel capacity while consuming 50% more because of the extra engine. Realistically, combat radius should be in the +/- 2500km range.

Which is exactly the range to the 2IC...
no, they specifically said Guam which is 3000 km away. That means 3000 km combat radius + loiter time.

50% more weight does not mean 50% more fuel tank. Also, 50% more weight and engine does not mean 50% more fuel consumption.

with latest material science tech & space + weight reduction tech, I expect doubling of fuel tank.

flywing designs allow for large amount of fuel in the wing and offers lower drag vs conventional designs that have tail

Also the 3 engine 3 intake layout allow for certain subsonic cruise mode that is likely very fuel efficient and low RCS.

If they say 10000 km range then I expect it can be used to strike target 4000 km away.

think Alaska.
Something that I have been thinking since the reveal

I really can't see how the B-21 can work as originally envisioned. Imo a high mach, high range, high endurance CHAD is the perfect counter for a subsonic bomber which has a "penetration" role
Yes, it is a B-21 hunter when paired with a bunch of UCAVs.
For 3km combat range, and some (non)permissions for overfly, it looks like all US bases in Persian Gulf and Gulf of Oman are more or less in range.

This will massively expand Chinese threat vectors towards US forces stationed in Middle East. Could now expand from Asia Pacific to the Middle East theater
Think farther. By the time this thing goes into service, China probably will have more control over central & South Asia, allowing it to presumably refuel overland outside of its territory if necessary. But realistically speaking, that’s not too important long term. Hitting Diego Garcia is a logical target.
This bird looks more like a "regional bomber" (think SU-34) than any kind of fighter. Range, stealth, internal weapons carriage, apparently side-by-side cockpit... it's got all the bomber-vibes in my opinion...
This is really poor analysis that’s very based on 2000s air warfare concept.

this is essentially a forward operating command & control aircraft that will be designed to operate close to enemy bases or far out fleet or loiter for long period of time to 1IC. Because it’s very survivable platform that can outrun AAMs & probably kill them with DEW.

What J-36 carries in its IWB is not as important as what UCAVs you pair along with it.

its inherently a multi role platform because its attacking prowess will come from the nodes that it control.

think of it as a central node (brain) with many other nodes that are manned or unmanned. Those side nodes will help it form one platform that attacks adversary.

they will operate as one unit for sensor fusion to computation to area coverage to attack missions to staying on station (some refueling drones)

hence the need for 2 pilots. It’s going to be controlling many nodes.

One other thing to keep in mind is that neither the J-36 nor the SAC bird is technically sixth gen by themselves. According to Yankee sixth gen is a collection of fighters, drones, and supporting assets. They are all pieces of a bigger puzzle.
Yes, very important to consider.

I spoke about this yesterday on my twitter space.

if you are still wondering what it can carry in IWB, then you are missing the point completely.

think system, think platforms.

that’s what all these old time analysts like Justin bronk doesn’t understand.

JH-XX is such an old concept. Think newer and bigger. It would be better if you think of J-36 as a super fast, maneuverable & survivable forward operating command & control aircraft.

it brings significant more cape than SAC design due to its sheer size, top speed & range.
