In the network published a photo of the secret "Product 30" for the Su-57
In the web there were photos of the new engine for the Russian fighter of the 5th generation of the Su-57 (PAK FA).
The new jet engine has the factory designation "Product 30". It was developed by NPO Saturn in almost ten years. Such an impressive time is due to the fact that this is not a modernization of any of the existing engines in aviation, but a completely new unit. It uses completely new design solutions, some are unique, not having world analogues.
"Product 30" significantly exceeds the engine AL-41F1, which is on the plane PAK FA at the moment. Its non-flexural traction is 11000 kgf versus 8800 kgf for the AL-41F1. On the afterburner - 19000 kgf against 15000 kgf. There are other differences: higher reliability, economical fuel consumption, increased overhaul interval, cost of operation.
Flight tests of the Su-57 with new engines should begin before the end of 2017.

So what is it? Al41 with Izd30 nozzle or whole Izd30?

How are we suppose to know for sure 
Austin's article says it's Izd 30

Through comparison with the Al41. I checked pictures of it and they look very similar aside from some pipe layout.

Doesn't prove they're the same....unless your a engineer familiar with the Al-41 I doubt you could say for sure

Said to be an early prototype of the Izd 30 nozzle

From an AL-41F1S (Su-35S) if I am not mistaken.

So there are plans/experiment/projects for a low-observable nozzle for the Su-35S?

I doubt it. I think they simply used the nozzle from a Su-35S and serrated the petal tips to trial it for RCS improvements?
For comparison:

Well the low observable tube on the F-35 just has serrated edges so doesn't that make this serrated edge model the stealthy one?

So, It's official.
The Izd-30 has flown in the Su-57.

Well this will blow some specific minds

Nice. They put the engine on an old prototype?

Is it just me or is the new engine shorter?

Izd 30 is noticeably less smoky on full afterburner during takeoff. That's a signature of a high tech engine delivering full combustion

B-b-but Gorenburg told us that it won't be ready before 2027?
And many Western publications proclaimed that Russia can't develop new engines? Certainly not anytime soon. Massive delays. How is this possible?
(I'm not an expert on engine development, but there's no way it's going to take another 10 years to become fully operational, right? Su-57 is already flying with one, ffs.)

The West will always find another excuse like what they did with Olympics to get Russia banned. Russia needs and should retaliate hard.

Afterburner is not engaged during this take-off. But the no smoke observation is a positive sign for good quality.

Maybe the engine was not working hahaha
They could reduce the price of the engine making more of them for future su-30 and su-35. So that maintenance of Su-57-30-35 will be the same and it will be simplier and faster.

OK folks, now we have new engine that is quite a bit shorter than old one. Here is a pic of airframe with covered engines. Once they put new engine in airframe like this one only thing that will be sticking out will be tip of the nozzle.
So one more nail in the coffin of the old ''Russia cannot into stealth'' fairytale.
Someone cold draw how the whole thing will fit now that we have both covers and engine size.

Absolutely great progress . Now the T-50 has a much higher T/W ratio than the F-22 or any other fighter being designed.
BTW is it possible for a serrated round nozzle to be made as stealthy as an f-22's flattened nozzle?
