J-20 5th Gen Fighter Thread VIII

Jokes aside, I too think that more powerful two engines would have made the design, stealth characteristics and the logistics better.

more powerful variable cycle engines are in final phase of development.

even if not VCE/ACE, they could have produce enlarge WS-15 engine just for more thrust. just build large engine. but they still goes with three engines configuration. it means J-36 is extremely power hungry aircraft for electronics/avionics so twin engines cannot fulfil the demand.

so your logic doesn't make sense. we have large low bypass ratio engines since 60's.

Reduce the size of the aircraft slightly, increase the thrust of the engines to 200 KN levels. Why prioritize supersonic characterstics over stealth characteristics and manufacturibility and economics of production? Every piece of hardware should be attritable in the modern battlefield.

I agree, if it just lack of more powerful engines they could just put 2xWS-15 as interim engine just like they put Al-31 and WS-10C on J-20. This means J-36 requires 3 Variable Cycle Engines to fully exploit its combat capability.

200 kN x 2 definitely wouldn't cut it for the J-36. Would've been fine if it's a bomber, but this is a fighter.

We're talking at least 250 kN x 2 class ones here.

Gyus ... we are in the J-20 thread? So why discussing here engine/powerplant options for the NGAD vs whatever the J-36 may use?

It's interesting to see how the discourse has shifted about China's existing 5th gen fighters since the J36/J50 has been unveiled. I haven't seen a single post about how the J-20 or the J-35 is actually a 4.5th gen fighter and not a true 5th gen ever since the 26th and comments about how China can only copy and steal, or how the J-20/J-35 is actually a F-22/F-35 clone have decreased a lot. Those two planes really woke a lot of people up it seems.

Every time I read something to the effect of "XX is a copy of YY because they look vaguely similar" I repeat a little mantra. Just because two things look similar does not mean they are the same or took the same pathways to get there. A bat and a bird look similar but they are not the same. Details matter.

Sometimes even very senior pundits and talking heads are as guilty of it as random commentors. They should know better, but at some level I think they may just be pandering. Unless they actually believe what they hear from parrots and want to join in the groupthink.

Generally it is way harder to enlarge an engine than to put another copy on. Like orders of magnitude harder. Both require airframe redesign, but enlargement of the engine is a whole new engine, new parts, etc.

Guys ... final kind try: We are in the J-20 thread!

LOL. It even cites 114514's evidence here. He is a troll among Chinese military fans and is constantly creating some paper that can make Chinese jets look inferior. The last famous incident was when he blurred a screenshot of a PLA internal document about J16 chasing F35 to imply that J20 was...
