To provide some context for the academic paper.
According to the original poster , roughly translated:
1. The general stats of the warplane mentioned in the paper (168-ton designed MTOW, 78.5-ton empty weight, 72.2-ton fuel weight, 17-ton+0.2-ton payload capacity with a combat radius of 4500 kilometers) looks to be close/roughly similar to that of the B-2 Spirit strategic bomber of the USAF.
2. The required bench thrust given in the paper is 114.22kN, but the warplane seems to already have a new, target engine (in the pipeline?).
3. According to the paper, the original engines slated for the warplane has a cruising fuel consumption rate of 0.7kg/(kgf·h), and the cruising fuel consumption rate of D-30KP-2/WS-18 officially given by Saturn NPO is 0.705kg/(kgf·h). Both engine models seem to be comparable to one another.
4. The new, target engines meant to replace the original engines are stated to have a cruising fuel consumption rate of 0.0679kg/(N·h), which is equal to 0.665kg/(kgf·h).
Possible objectives of the academic paper in question:
1. The warplane was to be powered by D-30KP-2/WS-18 at the beginning of the design, and they have already considered to replace them with new, target engines later on.
2. The paper discusses the methods of determining the performance parameters of the new, target engines without significantly altering the structure (of the warplane).
3. In fact, one major contribution of the paper is to explore the avenue of changing the engines without redesigning/reconfiguring the inlets and nozzles of the warplane.
Of course, we won't know whether said warplane subject in this academic paper is fictitious (for concept evaluation purposes only) or real (meant to represent actual plans to a certain degree).
The stats for the engine thrust and MTOW look rather... off, somehow.

he also said, this paper is from 2020..
remember this flight in early 2023.. Engine dimension indicate medium bypass ratio engine. either WS-10 or WS-15 variant. China don't have any application for this type engine other than large stealth bomber like H-20 ..
To be honest, it looks like an old and conservative proposal. The engines are apparently WS-18 derivatives, the MTOW is lower than the B-2 but the empty weight is 10% higher, etc... With that thrust of 46 tons and the 78 ton OEW, I would expect an aircraft above 200 tons in MTOW. These stats look off as you noted too.
