What you just laid out is roughly what I've been thinking for the past year or so. I have a theory that the PLA will become less risk adverse with military development as they get a better handle over newer technology, which means the conservative timelines we're used to to make our projections may be accelerated somewhat. This presumes that the project goes smoothly and they don't encounter setbacks however, which is always a possibility.

To bad it reports of now 1800 shp while i remember reading of 2200 shp WZ16 somewhere.

the difference could be continuous power vs takeoff power.

Anyone know what's the difference between WS-10A and B engines?
Thrust.

I really hope so, the 2200 shp would catapult WZ-10 to 2nd highest Attack Helicopter of shp/t in NTOW and MTOW.

Re: Shenyang J-31 Fighter
Brat, the RD-93 has been made a lot less smoky. If certain reports are to be believed, Chinese have tweaked it so that it runs at a higher temperature and produces more thrust as a result. Obviously fuel consumption would have improved too.
I can not say if these sources are perfectly credible, but PAF people are saying that RD-93 thrust has been increased by Chinese to the point where FC-1 / JF-17 TWR approaches 1.1
So one can think that this is a part of the progression of 'little' improvements that you were talking about in your post.

Re: Shenyang J-31 Fighter
I doubt Chinese could have make it run at higher temperature and produce more thrust, because that would mean changing some critical parts (like turbine blades and others ) that have to endure said high temperature . Russians are still somewhat ahead in material science (no disrespect to China , just facts ) and best they have for now in this class is RD-33MK with moderate increase of thrust . There is also prototype of RD-133 with TVC and max thrust in A/B mode of 91kN , but neither of these engines have been offered to China , not to mention Pakistan .

Re: Shenyang J-31 Fighter
You are presuming that RD-33 is still state of art and Chinese technology has not improve to the level of the Soviet technology as of twenty years ago, while Russian technology has not improve much since the fall of the Soviet Union due to the lack of resources and dispersion of expertise. And now China has some tools and methods that even Russia does not have. The fact that China has engines in development such as WS-15 that exceed the performance of the RD-133 makes your reasoning suspect.
