What is the AEP400 for, and how does it contrast with the AEP500?

And what does it say about them, for the benefit of this English language forum?
it didn't say anything meaningful except the title.
The title says it is bidding "the spring" used by AEP400 and WS-19E. (dunno what E stands for)
If AEW500 stands for power output 5,000 kW, AEP400 probably stands for 4,000 kW.

General
Not sure of the provenance and reliability of this table, but sharing it nonetheless. It lists several engine cores and their derivative products. Item No. 5 could be the WS-15 core (flow-rate of 30kg/s, turbine inlet temperature of 1,850K) and comes in three derivatives:
– low-bypass turbofan with afterburner (13,000 to 17,500 kgf thrust) for fighters.
– low-bypass turbofan w/o afterburner (10,000 to 11,000 kgf thrust) for attack and bomber aircraft.
– high-bypass turbofan (10,400 to 18,700 kgf thrust) for large transports, strategic bombers, and airliners.
– low-bypass turbofan with afterburner (13,000 to 17,500 kgf thrust) for fighters.
– low-bypass turbofan w/o afterburner (10,000 to 11,000 kgf thrust) for attack and bomber aircraft.
– high-bypass turbofan (10,400 to 18,700 kgf thrust) for large transports, strategic bombers, and airliners.
This is an old paper from the engine program’s pre-research days. It’s popped up in this thread several times over the years.Not sure of the provenance and reliability of this table, but sharing it nonetheless.

AEP400 is 4000kw compared to 5000kw of AEP500.
It is likely the engine for Y-30 which is a deriative of Y-8 lineage. WJ-6 family used by Y-8 and Y-9 is 3500kw class, the latest is 3800kw. 4000kw is a further improvement for something new like Y-30.
Odd.
Shouldn't the Y-30 be a complete upgrade upwards over the Y-8/9 (e.g. greater payload capacity, better flight performance, longer range)?
Why should the Y-30 opt for a less powerful engine?
