General
Excerpts from an academic paper (published this year) comparing performance parameters of AES100 turboshaft, AEP100 turboprop, and AEF100 turbofan with those of selected foreign counterparts. Of course, these engines are all derived from a common core. Interestingly, there is one more variant (derived from AES100) not yet unveiled: a gas turbine used in armored vehicles with an output of 900kW (table 9), and it was deemed to have comparable performance with its piston-driven counterparts (more on this below).
Excerpts from a 2022 paper on the aforementioned gas turbine for armored vehicles. Conversion and testing begin at the end of 2020. The paper also mentions R&D into a 2000kW gas turbine for armored vehicles (probably derived from WZ10 turboshaft), along with a hybrid drive outputting 250kW.

Allegedly the intermediate compressor case for the next-gen low BPR three-stream ACE. 1349 x 1357 x 328 mm.
Not really news per se.
China is developing a 250kN high-bypass turbofan engine.

There's no doubt China is developing new large high-bypass ratio turbofans. But 250kN is weird in my humble opinion. Nowadays 4-engine commercial jets are fading away. Considering 2-engine models, 250kN is obviously too large for B737/A320 or even B757, but too small for B787/A330. This thrust is good for 150t-200t MTOW, i.e. some versions of B767/A310. But as you can see B767/A310 are also retring, and China has little demands of Trans-Altantic range flights.
If they are really developing a 250kN turbofan, I will prefer the possibilty they wanna join the game of C-5/An-124.

It is exactly in the thrust range a 4-engine 400-plus tonne military transport aircraft would use. And it is also too weak for a new widebody airliner. If this engine is real it would be the strongest evidence for me so far that China is indeed developing a super heavy transport.
if you read my old massages. i have already tell, Shenyang Aero Engine research institute is working on 25 tons High bypass turbofan Engine.
Shenyang also issued a tender on 14th November for certain type of testing equipment.
