Chengdu J-20 'BLACK EAGLE' - History, Design, Performance & Discussion

This is maximum thrust it can get in theory. However this is the design and not actual aircraft. 19.1 kN is the stated requirement. I would assume this is achieved under optimal conditions.

It is not the same as discussing 70s engine designs from bench to installed. There may be losses on bench as compared to installed and who knows if the bench number is the actual maximum output in static conditions or if it can handle much higher output at even low or moderate speeds once airflow through the intake is sufficient.

There are too many variables, quit replying to this if you have nothing of substance to use for comparison.

Gunfighting seems to be dead. I’ve never heard of a gun being used on anything other than helicopters.

The J-20 is a pure missile bus with long range designed to hit tankers, AWCAS, and other support elements hard and fast. If it gets into the range or helicopters that PL-10 cant handle then he messed up badly.

Classified numbers are irrelevant for this context, it will be added to the game with the publicly available numbers.

Haven’t they been used on shahed style drones and other large UAV?

You don’t even know that, many of the current in-game fighters use numbers from the land of make believe including stuff like the Su-27 and MiG-29 even when real values are available.

Yeah, but you don’t need a 5th gen for those roles. China has J-16, J-15, and J-10 that have guns.

Yeah but funny stealth plane dogfights.

If it interests you, the J-35 (carrier variant) apparently has an internal cannon.

Mostly on helicopters with rotating turrets

Huh?

anyone have images of cockpit from this?

Do yk how many cms it has? I remember it had cms right next to the engines, but only time i saw them i think they were covered

Can barely count the dispensers, but I think 108?

Uh… No. Absolutely not.

It is inherently variable bypass especially in the model the F-35B utilizes to guide air through the stabilization vents and to modulate how much is making it through. The others simply cannot utilize the variable bypass the same way as a traditional variable bypass would - yet the core and features are still the pinnacle of fighter jet engines on any in-service aircraft.

TL;DR
You’re right, the F-135 is not a traditional variable bypass ratio engine (something we’ve been producing since the 70s), but it does still have a variable bypass air duct.

Ah, I must have missed where the convo was on the F-35B, I had the F-35A in mind.

I believe it can still vent cold bypass air on F-35A without needing to accelerate it in the hot section to overcome losses like on the F119. Could be wrong.
