This link shows a little bit about it, albeit I don't know the source's credibility.

Su-57 Radar scattering simulation

This is not a "very suspicious photo" but screenshot from GLITz anniversary video. It's interesting that you give link to the original Twitter post that has both link to _original video_ and description of actions author made to inlet screenshot to rise lightning level using _Photoshop_, but even didn't care to use Twitter translate to understand that.
'Aah, Photoshop, familiar word. It's PSed then, period.'

As I mentioned PS is not the problem. If someone used PS to 'expose' that radar blocker it's OK ,both of us were right ( 'cause I wrote that ''it is nothing but PS '' of course my thoughts was that someone inserted that grid inside of the air intake....). By the way, here is the 'original of the original.' ( 19:04 )

Prototype was Bort number 510 blue if I am right. What someone exposed to all is somewhat closest to 'Figure 3' in the Patent doc.

Now as I wrote earlier ,all of this is not the main issue. From all the photos/videos of the serial Su-57's in the KnAAZ that I have, there is no trace of that grid. From the newest doc. film ( 45:57) ,we can see air intake but there is no radar blocker.

Some photos of the air intakes we have on this page ( as sequencies from the doc. )

So my opinion is that it will be good to found those radar blockers during serial production if it is possible.Then we will be sure that serial Su-57's really have coaxial-radial grids.
I am trying to find that radar blockers during serial production for years now but there is no trace of them.When I first saw that PS -pic from 2020 ,I thought they really had those grids( on the prototypes). After a lot of attempts to find them, see them on the serial Su-57's, I started to think that picture was created as a 'real PS', i.e. that someone drew a grid inside that air intake.

Questions are: are they used radar blockers on the prototypes Bort number 509 and 511 that were in the Syria on Feb. 21-23 2018 and later?
Do radar blockers inside of the air intakes have/had air mas flow issues for the engines?
We don't know many details but as any product these radar blockers have their pros and cons,reducing frontal RCS and maybe,maybe producing some problems with air mass flow in front of the IGV.

The Su-57's radar blocker has been discussed on this forum for years.

OK,what was conclusion then ?

Just go on on your own and read thru the thread(s)! It's really annoying at the moment that in almost all flagship-threads new members constantly bring up some unfounded stuff, the discussion goes on for pages all about nothing and nonsense, senior members with a long-established credibility are no longer taken as more credible than newbies as if any opinion would have the same value and instead of being able and willing to read, listen and lean one has to accept all their nonsense or at best have to present former discussions since they are too lazy to do it alone!

Pretty much beat me to it. There are a number of threads devoted to The Su-57 that go back almost two decades, now, & the intake design & the use of a radar blocker have long been sources of contention depending on your opinion &/or priorities, so...have fun reading .

What is YOUR conclusion?

If there is no "radar blocker", how does the Su-57 prevent radar waves bouncing off the engine fans? How cn it be 'stealthy' if this is the case?

The Boeing X-32 was unable to use an s-duct due to main engine location, so it used a blocker.

For crying out loud...

Yes, there is a radar blocker there. That's it. See my earlier post.

I'll take the time to compile a selection of relevant photos, videos and docs, in chronological order, to put a definite end to this crap. Perhaps this evening, unless somebody else beats me to it.

Don't understand why that'd even be necessary, but whatever, I guess?

Nah, just let him read over the threads for himself.

Is there a production aircraft video I could use to put this to rest?
