I would like to be corrected if I am wrong. But as far as I know, Izdeliye 30 is the name of the main engine of the SU57 while it was being developed in to AL51-F1. (24000lbf dry and 38000lbf wet thrust). This engine is for Russian use only.
Izdeliye177S is basically the AL41-F1S engine using AL-51 technologies. (~21000lbf dry, 33000lbf wet thrust) This is the engine to be used in export version of SU57 and new SU35 jets.
If memory serves, AL51-F1 engine is the first engine Russians are serially producing that contains single crystal turbine blades.
Izdeliye177S too is supposed to have single crystal technology.
Yes, that's correct.
But there's one interesting nuance, albeit not entirely subtle. The fact is that the "AL51F1 engine, also known as 'Product 30,' is not yet ready. And there's not even a hint that it will be ready anytime soon!"
That's the thing.
In other words, the Russian Su-57 fighter doesn't have an engine! Just like the KAAN, I might add. The difference is that the AL41F1 is Russian, while the KAAN's is American.
Development of the AL51F1 began in 2001.
Product 177 is not a new engine, but a modified AL41F1.
As a reminder, development of the Su-57 began in the late 1990s. The prototype's maiden flight took place in 2010—16 years ago!
During these 16 years, 35-36 units were produced. Just today, a batch of three or four fighters was delivered from the factory to the troops.
Interestingly, India joined the Su-57 development program in 2008 but withdrew from the project in 2018 due to technical requirements.
Yesterday, a video from Algeria appeared online showing an Su-57 in flight. Apparently, Russia has sold two of the 12 aircraft ordered to a foreign customer for the first time.
