What is the black rim material on the weapon bay doors?
Probably ram coated seal to cover the gaps ..? Since, incase of engagement, the bay doors are likely to undergo a lot of mechanical activity under high stress conditions.
All very neat pictures, but picture 1 shows the canard with downward pitch related to the main wing, obviously creating vortices lift, my Bud the Engineer would note that there is significant alignment with the relative wind, while the main wing is likely about 4 or 5 degrees positive angle of attack, but I would suggest that it has a slight negative angle to the relative wind in order to generate a substantial vortices, and enhance lift produced by the main wing, the aft surfaces on the main wing are therefore "pitching the nose up for a positive angle of attack"...
this photo illustrates the complexity of the FCS, and those computers, sensors, angle of attack probes are punching a LOT of information into the FCS,,, this is a very busy FCS, the distant coupled canard adding to that complexity....
Picture #2 is awesome from an aesthetic standpoint, the 15 degree or so bank angle with the backdrop of being in a valley below the trees on the ridgeline, beautiful picture, and shows the "meta material" on the leading/trailing edges, just an amazing little airplane!
Actually they can't, the Raptor is able to work its magic with supercruise up to Mach 1.8, the Raptor has excellent range, and yes it is the instrument of choice for a deep strike fighter as it's speed and L/O are the best...
there are faster fighters, but they are throwing a radar/IR return the size of a "steel mill"! the Raptor is quiet in respect to RCS and IR in comparison, and its range is much better than fighter with Reheat at Mach 2+...
but we are the J-20 thread, LOL, so the J-20 would stack up fairly well with the Raptor, but is anxiously awaiting those WS-15s and their projected supercruise....
Last batch...
lots and lots of RIVETS on top where they don't cause a problem.. with RCS, lots of bonding in other places and lots and lots of meta-material on every exposed leading and trailing edge surfaces as well as gear doors and weapons bay edges..... this is a very pretty airplane with a very high build quality...
Deino, did you get to see any of those Chinese Flankers or J-10's up close??
Some very detailed high-resolution close-ups of J-20... The first one is especially excellent. Note the two white rectangular devices installed at the front edge of the belly bay. They are likely there to deflect air flow.
that's right, you don't want that turbulent air in your weapons bay interfering with weapons release and ignition, that turbulent air in the weapons bay could also contribute to a very heavy buffet particularly if your supersonic....
There's definitely some kind of treatment on the canopy; in almost all of the high quality photos we can see the canopy isn't transparent but some of the light reflects in a rainbow in a way not seen on other Chinese fighters.
Considering some other aircraft like J-10B/C have a slight gold sheen to their canopy suggestive of a treatment, I suspect J-20 likely uses some sort of coating as well.
Its a darker colored Meta Material designed to absorb radar waves during the period of time that you have those bay doors open.
