You need to calm tf down.
Chengdu next gen combat aircraft (?J-36) thread
- Thread starter Blitzo
- Start date
hmmmmmmm is this comment an attempt at preserving military secrecy??
How could he know what "experts" are thinking? Expert opinion are not yet publicised ... experts meaning Pentagon, not youtube "experts" or SDF "experts".
Assumign all this at face value, it would therefore indicate the CHAD is less of a long range , high speed, possibly high altitude BVR focused fighter/A2A arsenal aircraft. Maybe CHAD is JH-xy?
A multirole JH-xy - supersonic air superiority and strike also possibly separate EW, C4ISR platform.
Which would make Shengad the air superiority focused 6th gen, with variable airframe to fit different flight profiles.
H-20 therefore is strategic stealth bomber and have very limited A2A role. Unlike B-21 is hinted to take.
Orca commented on a translated version of this:
Here's a more effective explanation regarding the EOTS on both sides of the aircraft nose. Have you heard of stereoscopic vision? It simulates human binocular vision by using two cameras to capture the same scene from different positions. By calculating the disparity of corresponding points in the images, the distance to the object can be derived.
We have discussed too many irrelevant aircraft, so let’s go back to the J36. I always thought this aircraft would do something maneuverable. Take TVC for example. If you enlarge the image, you can clearly see the three jagged structures of the tail jet port, plus 6 huge raised action cylinders. Such a huge transmission mechanism will only be needed if it is foreseen that it will be subject to huge pulling force. It is maneuvering at high speed that produces such a large g-force. Compared with two-piece flaps, which only need to move at low speed, there is no bulge in the transmission mechanism at all.
It sacrifices high AOA capabilities you see in knife fights for better supersonic maneuverability.
Position over pointing.
Imho here you see it has TVC clearly, since the nozzles are quite literally pointing at different directions.
It's just a question of how exactly it was achieved with so minimal movable surfaces.
Since there is a real stability problem present with removing vertical surfaces on designs like the J-36 in terms of yaw stability, I don't really think thrust augmentation with two engines by reducing fuel injection on one and increasing it on the other (not possible at maximum thrust), provides enough transience to deal with the rapidly changing flow characteristics at high speeds. Engines would require too much time to slow down and speed up to react to the changing conditions of the flow. I think it is very possible the PLA thought they could solve this problem by bleeding air from the side engines into the center one through some sort of valve or door downstream from the turbine and upstream of the convergent-divergent nozzle in order to obtain such rapid reaction times. A solution like this may also help with preserving speeds since thrust isn't lost, but rather transferred to the center engine where no moment is being produced in the yaw direction. Just a thought that popped up in my head and thought it was worth sharing.
It is well known the TVC on the F-22 isn't just there for dogfighting. It is also used for pitch and roll stability at altitude in order to keep the control surfaces from moving and preserve LO integrity, because canted stabilizers require other control surfaces to kick in, so without TVC, the control surfaces would be very busy. The other advantage of doing this is the nozzles have more air volume at higher speeds than forward motion alone, so lower deflection degrees may be needed on the nozzles than ailerons and flaps, further helping LO.
Since the J-36 heavily prioritizes RCS reduction and lacks vertical and canted surfaces, it may very well use TVC for the same reasons I mentioned above. TVC also helps greatly with STOL, which may be necessary for the J-36 wing configuration and MTOW.
You may be right, but the slits between the nozzles that @Nx4eu mentions, do remain a big question mark. They have to be there for a reason.
