This scheme practically begged for my little addition.

LOL! I wasn't sure at first if I wasn't imagining things

That's probably the idea. I wonder if they'll start trying to encode hacks in their camo schemes to reset optical seekers.

Interesting story.

Is that an alien from Space Invaders on the right side???????

Yes.

 

[flateric]

In real life.

I'd indicated I doctored it. I saw the pixelated scheme and that's the first thing that popped in my head to do. (I blame growing up in the early days of video games. ;D )

Finally T50-11 '511'

[stealthflanker]

and as said before.. the 510 would made late appearance :3

 

[flanker]

Certain modifications had to be done while both were in production after testing of earlier frames. Since -11 was earlier in production flow it just received the modified parts while -10 had to be reworked, hence taking longer.

I've read the September 2017 Air International article on the Su-57, and the electro-optical systems of the aircraft strike me as odd and rather redundant. The missile warning systems appear to be UV-based, which is optimal at detecting a burning rocket motor, but considerably less effective when the missile is coasting. Meanwhile, there are (at least) three separate IR sensors: the IRST located by the canopy, landing/navigation FLIR camera on one of the SRAAM bay fairings, and a targeting pod. I can't help but feel that there's quite a bit of redundancy there and that that something like the F-35's EOTS could've served all those functionalities.

 

[kaiserbill]

After rumours earlier in the day about the first flight on one of the Su-57 prototypes of the new Izd-30 engine, pictures and videos have emerged on the web of the Su-57 flying with what appears to be a shorter engine/nozzle with that new recently seen serrated nozzle.

 

[flateric]

recently seen serrated nozzle has nothing to do with Izd.30

 

[LowObservable]

According to Google Translate, the T-50 design incorporates "innovative digital stuffing". That'll get you fired from NBC these days.

I believe it's because they are all developments of existing systems rather than a brand new design. Cheaper and easier but less capable.

Do you have a single piece of evidence suggesting any of them is a development of an existing system, let alone all of them? What system is the predecessor of KS-U? Or KS-O? For example Su-35S uses an IR-based system for MAWS and it looks totally different.

The new LOAN-type nozzle seems slightly shorter and possibly slightly larger diameter. It doesn't seem like the engine nacelles would be reshaped much, if at all.

As I understand it, the electro-optical systems of the Su-57 are developed by UOMZ (the firm that also made the OLS-27), while the Su-35's systems, at least the missile warning systems, were developed by a different firm; how much technology is shared between the two aircraft's systems is unknown. Regardless, the question still remains as to why the Su-57 has three separate infrared sensors with a fair bit of overlap between them; at the very least, I would imagine that the landing/navigation FLIR camera and targeting pod could've been rolled into one onboard system.

 

[ScrutorAudax]

I don't know if these were posted yet, but here is what I found.

 

[Deino]

AFAIK the image of T50-10

 

[Deino]

Two more nice shots ... one showing again 510 and one another bird with an RF-number. ???

Also, none of the camo-pattern fits to 09, 10 or 11? Any idea?

 

[Trident]

Well spotted!

T-50-11 repainted and assigned a RF-reg for deployment to Syria?

T-50-10 seems to lack the MiG-29/Su-35 style windshield heating elements.

Indeed ... RF-81775 was allegedly:

First Sukhoi Su-57 in service with Russian Air Force, has been to Syria. First one to wear RF- registration.

But I agree with "Red Samovar" that it is most likely a slightly modified T50-11:

[flanker]

It is -11 of course.

Surprised no one talking about India pulling out of the SU-57. Is the program in that much trouble?

Surprised that you still don't know the difference between PAK FA and FGFA

[stealthflanker]

and it fire stuff i guess

https://www.youtube.com/watch?time_continue=4&v=iACk08Gp2HE

apparently it's Kh-59MK2

Which is wonderful, i always fascinated on Kh-59MK2. Compact, long ranged and certainly can be carried in numbers. Would make wonderful standoff weapon alternatives for Flankers.

An interesting video, I wonder what other weapons they will be test firing or dropping (in the case of bombs) from the Su-50 weapons bays and hardpoints? B)

 

[LowObservable]

As reported three years ago...

 

[FighterJock]

Oops, sorry about that, my mistake. The sands of time. :-[

 

[Avimimus]

I missed it! I've only ever seen CGI of weapon releases.

 

[LowObservable]

Sorry, FJ!

The video is new. The weapon was at MAKS 2015 and was linked to the Su-57 at the time.

The expert, speaking on condition of anonymity because of the sensitive nature of the stealth work, highlighted six major problems with the pictures.

The seams between the flaps on the aircraft are too big. Taking the F-22 stealth jet from the US, the flaps on the end of the wing have very tight seams that don’t scatter radar waves and therefore maintain a low profile.

Secondly, the Su-57’s vertical rear tails have a wide gap where they stray from the fuselage and according to the scientist, it is essential that a stealth keeps a tight profile.

Looking at the F35’s rear tails, for example, and they touch the whole way.

The nose of the Su-57 is also problematic as it has noticeable seams around the canopy, which eliminates stealth, while the F-35 and F-22 feature a smooth, sloped appearance.

 

[LowObservable]

That entire story appears to have been created via Google Translate. And the original Business Insider story is by the same guy whose "scientist" source was dumping on the J-20 a couple of weeks ago.

Can you refrain from reposting BS from tabloids? Thank you.

 

[kcran567]

I can see some features like rivets/screws on the fuselage that would affect stealth, and is there yet any pictures of an installed radar blocker for the inlets yet?
