Chinese Engine Development

My OCR says it has to do with CNC software. Is that right?
The Chinese texts are "数控", literally means Digital Control. Chinese technical terminology does not give a unique translation of CNC (Computer Numerical Control) different from any other digital/computer control. All are translated to "数控" short form of "数字控制".

For example, FADEC (full authority digital engine control) is 全权数字发动机控制. CNC is 数字控制机床.

In the posted photocopy, they are all referring to turbofan engines, so they are not CNC, but FADEC software.

Around 132000 kgf for both of them.

Thanks. That's barely 130 kN. Puts it in the class of the F110-GE-129. For the J-10 that would suffice, but rather low for 5th gen aircraft. o_O Maybe it has an emergency mode similar to the Saturn 117/117S but at the expense of MTBO? o_Oo_O

I am wondering whether the max dry thrust in the WS-10C is higher than the AL-31. That would help with supercruise for the J-20.

Maybe WS-10 is shorter and lighter..

It would make sense to "overclock" the WS-10C when it's installed on the J-20. Get the extra performance out of it and by the time it burns out the airframe can be re-engined with a WS-15.

The important thing is to increase the total number of J-20s right now. Performance enhancement can wait.

It is really hard to follow the many attempts and milestones of China in the aircraft powerplant field. I am preparing a small Chart to better make sense ( for my very modestly capable brain atleast) of the developments.
I will be expanding this chart to include any and all Turbofan developments of China. I would be excluding very small Turbofans and include Civilian turbofans. I need the occasional help from other members. This chart would really be helpful for anyone ( novices and not-so-technically knowledgeable too, I hope) in understanding all the Progress and setbacks China keeps encountering in this commendable endeavor.
I have compiled te chart from the information available in the thread itself ( posts starting from 2016). Inputs are welcome (and would be really helpful).

Some questions :
1. The Naval version of WS-10 ( H series?) is to have better thrust. Is this true ? If so, what is the thrust improvement?
2. The WS-10H series would also need to have a better power generation (electricity) to support the J-15D (EW subsystems as well as AESA radars). So... Is the WS-10H a higher thrust with Higher electricity output ?
3. Does the J-16 use WS-10H ? ( J-16D specifically since J-16D has a connection with J-15D?)
4.WS-10IPE/G evolved into WS-10H. Is this probable? Or is the WS-10H an evolution of WS-10B (improved) ? This is quite confusing.
5. How do we distinguish between a WS-10C equipped on J-20 with a WS-15 ? The "chrysanthemums" petal design and operation holds the key ( along with the length of the WS-15 engine) Isn't that right?
