Given that the Il-76 and Tu-214 will continue to demand these engines , it will probably be useful to make a PIP that can be easily slipped into new aircraft and replace older engines too.
PS-90 will be in production for a long time in one variant or the other simply because it used on IL-76, IL-96, TU-204, etc. PD-14 amd PD-35 are new and untested. Time will tell.
PD-14 can replace it on IL-76. PD-35 for IL-96. If they are redesigning Tu-214, the PD-14 can be a better option. All are future predictions of course. In short term, PS-90A will be in production.
if you look at the USA C-17 transport jet - similar to the Il-76 .... its engines aren't that different in performance to the PS-90. P&W 2000. Interestingly that same engine was used widely on the Boeing 757 which is very similar to the Tu-2014/214. there are numerous gas industry uses of the PS-90 too ... for power generation and gas pumping and its reliability ensures its future for a long time
While one PS-90 version may be produced for Tu-214 and IL-76 for sometime, ultimately PD-14, will take over these functions for better performance matrix. I am sure if C-17 Nd 757 would have seen re engine project if they had the required volumes.

PD-8 and PD-14 are currently undergoing tests, the 2 engines may complete the test in 2025,

PS-90 is a bit of an overkill for Il-76. The plane is smaller than C17 but have almost same thrust engines.
How about it when compare to Progress D18T turbofan.
D18T is meant for heavier like the An-124.
There should be a special comparison for those engines that no one makes.
You are comparing *NOT EXISTING(!!!) engine PD-35* with existing and used on many aircrafts engine PC-90.
It exists actually. Although is not production ready yet.

PD-35 ? Better focus on PD-14 & PD-8 first. Get the production volume of those two variances first.
I think they need to put this engine and il 96-400m into the production soon in order to get their money back. RnD has never been cheap.
