This is how the F-35 looks like in reality.
And the F-22.
Yes, and look at all the tape and paste treatment on all the joints! They look like cardboard airplanes with all that composite and taping. Outstanding. We haven't seen this stage for the PAK-FA yet. I can't imagine they won't treat the bazilion riveted joints on that aircraft with some taping like the US jets.
And if you go closer towards the F-22:
There are some access panels that need to be got at on a regular basis as part of pre & post-flight inspections, along with other critical parts of the aircraft that the crew have to get to. Gas port, gun amo port, grounding and electrical connection etc. So there will be some that just have to keep their screws exposed like the one in your picture. No-brainer, especially on the larger panels that can't be made with pop-in & pop-out locking mechanism. All the other permanent panels that are riveted are seamless and you can't see them whatsoever. Some of the panels on the F-35 are even rivetless! They either press them together or connect then in some other way but the process and workmanship is impeccable. We need to see that in the PAK-FA before we give it any accolades on stealthiness, and we haven't.
Otoh, PAK FA is either not painted or is painted using light colours like blue.
The only thing going for it in this respect is that they haven't gotten to any RAM applications yet. So we don't know how they will treat all those riveted panel joints. But the shaping is still worrisome compared to the F-22 and F-35 and even the J-20. If you look at the Chinese bird, they've addressed the panels and RAM aspect in excellent ways, just like the Americans. We have seen nothing from the Russians yet.
Credit the Chinese BIG-TIME for what they've created with this absolute beauty. Look at the panel connetions application. Flawless.
Click on both images to enlarge and take a look at the exquisite quality of the panels prior to even painting! It's unbelievable.
Even the weapon's bay gaps are MUCH tighter on the J-20 than the PAK-FA.
AND, flat belly just like the F-22 and F-35. Why is the PAK-FA ignoring that most critical design aspect?
Look at all the saw-tooth edging they've painstakingly put into every single joint on the BACK of this monster!
They've even saw-toothed the trailing edges of the flight surfaces. Neither the F-22 nor the F-35 are making this application. Nothing close to anything like this that we've been able to see on any of the 11 PAK-FAs to date and the Chines have only 6 of these J-20s! I really don't understand what the Russians are doing.
With the finish paint & RAM.
Those are side bays.
In a pic you posted, you will notice the crease for the door.
Look closely just below the LERX, there is a prominent line there.
Did you even read that that's what I said? Yes you can see some outline of a panel on the fairings so they're obviously for "something," but here's the problem with automatically assuming it's for a missile. The size of the faring is barely enough -- even for an R-73 -- let alone the necessary mechanisms to extend the missile out of the fairing so it can be jettisoned far enough to clear the wing and have its rocket motor fired.
Here's a close-up and I'll get to the circled part in a minute. There's the seam for the fairing panel but it's way too small for a missile and associated, necessary hardware. Never mind hinging mechanisms for the panel itself!
Look at that fairing which is barely big enough for a packed R-73 with completely folded fins and definitely not enough room for an extracting mechanism and panel hinges. If you look at the extraction arms on the F-22 and F-35 weapons bays, there is some substantial amount of hardware that is needed to hold on to those missiles and extend them out to clear the aircraft; far enough from the body, wings and fuselage (similar to a pylon's job) and these fairings don't look like they have anything close to that kind of room. The weapons bays also have large hinges and hydraulic brackets to push open the panel, hold it in place and close it. Nowhere near the room for all that.
The other thing to consider is that those fairings can have a multitude of other functions like I mentioned. They can house sensors, EW equipment etc. Something similar in the Ka-52 we looked into a while back. That helo carries what looks like a weapons pod and there were rumors that it houses a series of small, UAVs that the helo would launch to recon the battlefield ahead of the chopper but we found out that it was neither, and more likely an electronics pod of some sort or even just a toolbox for the pilots.
This is the pod on the left wing of the Ka-52:
Now look at it when it's opened up! All sorts of "stuff" other than weapons.
Those are EW/ECM pods of some sort on the PAK-FA.
Back to that red circle: that's an inlet brace. What do you suppose that will cause when radar waves get into that gap between the intake and the LERX and reach that brace? let's hope and pray that's temporary and will not be on production models.
The same, glaring issue is with the belly of the bird like I've mentioned twice already.
Why do you suppose all these stealthy aircraft (including the F/A-18) have canted vertical stabilizers? I know you already know this so I'm not patronizing you in any way, just trying to make a point. It's specifically to avoid the 90 degree connection at the joints of the tails to the body, basic knowledge. Now look at the belly of the PAK-FA and the joints between the dropped engine runs to the flat, center belly where the weapons bays are. That's a brutal, elongated 90 degree joint. Those radar waves are going to have a field day when they get trapped in that corner and start bouncing around sending back an almost perfect image of the bird! There is nowhere for them to be deflected away (which is the essential function of stealth shaping) and too much material to just use RAM as you also have to consider the temperature factor where the engine nacelles are and how RAM would react to that. This is probably the biggest concern I have about this bird. Is it a spot for plasma? For some SPECTRA-like antennas to help absorb and reshape radar waves? We don't know, but what we know is that specific are of shaping was taken very seriously in the F-22, F-35 and the J-20 but not in the PAK-FA. I would say that's a big problem and nowhere near any level of 6th generation.
As for the radar, the IAF's asked for a "brand new radar which does not exist", so we don't know what that means.
Well, that is a problem because the radar is also a HUGE part of the overall stealth package, and the US has been fielding AESA radars for a lot longer than the Russians who are still trying to produce a viable, AESA production radar. So they're behind US technology levels in that respect which also beats down this notion you have of the PAK-FA being a 6th gen platform.
