Integrated heat pipes? Fuel as heat sink? Source: https://lt.cjdby.net/forum.php?mod=viewthread&tid=2633928&extra=page=1&mobile=2

According this paper, yes.
It's kinda of mind blogging to know how sophisticated the design needed for 5G fighters.
This heat management system is to reduce weight and infrared signal as the paper mentioned.

From my point of view, photos of those with yellow primer coating indicate that J-20 with WS-10X are already under ongoing batch production.View attachment 649305

The J-20 really has amazing workmanship ... such a huge improvement since the days of the J-10A. I really think the level rivals that of the F-35 or F-22. Meanwhile the Su-57s workmanship leaves quite a bit to be desired.

Fifth generation fighters are more sophisticated than we could even imagine ... just imagine what goes in the stealth coating alone.

Designing engines and aircraft using heat capacity of aviation fuel is old now. Just did not incorporate in WS-10 and works from 1980s and 1990s such as J-10 series. However the theory always ongoing and WS-15 and J-20 design incorporate fuel's heat capacity to manage thermo efficiency of engines and manage heat signature of aircraft. This is old information.

No way F-22 carries so much liquid nitrogen. How does it keep it under such pressures for gradual use? It will take too much space for 2 tonnes of pressurized liquid nitrogen sealed and using valves to release every 10 minutes? I think this is just rumors. They used similar engine heat management like F-135 and F-35 does.

I am just a beginner at chinese... Hope to get better in the future

Someone on CJDBY says that 20 or more of recently built J-20A (J-20 with WS-10X ?) will enter service in coming months.

PS: They definitely look being built in batch production as all test aircraft in China we have seen so far have been painted with finishing coating before their flights. In that regard, a flight with primer coating on the aircraft normally means a trial flight for delivery.

Didnt we get pictures of the Taihang J-20 production types as far as a year ago? Why would it take so long for them to enter service? Or does is the poster suggesting these already entered service?

I think they are still being built in small batches and not in full production.

China should skip this jet and stall for time to get to 6th generation fighter.

WHY TELL US

WHY TELL US

China would be better in all aspects by 2030. New engines, submarines, stealth bombers, better drones, more carriers with jets, more destroyers....

China is not ready right now for war.

How can it skip a 5th generation fighter and move on to 6th generation? Please enlighten us ...

The plan is 2035 for 6th gen right? That's not far away.

J20 feels like a half baked 5th gen. China's next jet should be on par with US next gen jet.
