701JAC is air cooled. It is in the same class as the air cooled 9HA from GE both in the 1650C+ class.
This is just a reference for state of the art power plant which while different from aero, the material science is similar. The power plant blade materials are all flown down aircraft technology.
If we only just managed to produce E class GT domestically, which is 1300C range, and WS10 is 1500C range, it just shows that we are 2-3 generation behind. (F class at 1400C, H class at 1500C, then J/HA class at 1600+)
Keep in mind that next gen for GE & MHI is 1700+ & 25:1, and F135 is at 1950C for comparison.
We are catching up, and the products are good enough, but we are nowhere near the top yet. When WS15 goes into service, we will probably see F class in China, or H if they make a leap.
Getting to H class would be awesome as the efficiency gains to J class is only around 2% for 200C increase inlet temp. We are at around 65% efficiency today, and to get to the next goal of 70%, there kinda needs to be a revolution, so it isn't like US/Japan will pull away while we catch up.
Russia has similar issues. And as a country rich in natural gas resource you would think they would be in the head pack of this field.
They used to buy German gas turbines from Siemens. After the annexation of Crimea, when the Germans sanctioned sales of gas turbines to Crimea, they started a crash program to develop their own gas turbines.

Personal opinion
Civilian turbofans;
1: US, UK, France
2. Russia, Japan, Germany
3: China
Fighter turbofans:
1: US, Russia
2: China
3: UK, France
4: Germany, Japan
UK and France should be ahead of China in fighter turbofan.
EJ200 and M88? Yeah but none in the 120kn above class.
I forgot about civilian engines. Should China and Japan even be on that list? AFAIK neither have produced their own domestic engine for civilian aircraft

French have their inhouse "Silvercrest" turbofan under development, thought it's for smaller planes like business jets, i'm not sure if they got plans for anything bigger tiebofans since French have their hands on other pies already.
What I know is that French engines are seen very realiable.
