J-20 5th Gen Fighter Thread V

He also talks about high degree of sensor fusion. He describes it as if he is feeling the wind on his own skin and being able to see and hear everything.

I noticed the HUD has evolved from earlier versions:

I noticed the HUD has evolved from earlier versions:

I think that was obvious quite a few years ago since prototype 2011, which had the current slimmer HUD (present on all 201X prototypes and current LRIP planes), compared to the J-11B/J-10B pattern HUD on prototypes 2001/2002.

if you missed the parade, J20 and J16 can be seen from the 51 minute mark

Interview with Chengdu J-20 Stealth Fighter Pilots

What I get from Pilot's interview : Confirmed that Chengdu J-20 have Super-Cruise ability.



And also..

The leader of the J-20 squadron said "The maneuverability of our J-20 fighter is especially good. At subsonic speed, its very good already, but once it entered supersonic speed, the world belongs to him."

Supersonic does not mean super cruise.

Unlikely super cruise with old Russian engine.

Yes, however the way the pilot phrases it makes it seem like the aircraft's kinematic performance in the supersonic regime is a normal or routine thing for the aircraft to do, which is rather suspicious if the aircraft must use afterburner to achieve supersonic speeds.

I also thought supercruise is unlikely using the current engines, however I think considering J-20's configuration not only as a stealth aircraft with internal weapon bays to reduce drag, but also an airframe that seems longer and with more of a "long delta" configuration, I would hazard to say that supercruising may not be out of the question.
Obviously any such performance would be well below what could be achieved with the intended WS-15 engines, but if the aircraft is using the more powerful Al-31FM2 engines (145 kN compared to F119's 156 kN), I wouldn't put it past J-20 being able to achieve a lower end mach 1 supercruise even when not using WS-15s.


Of course this is all speculation and I think daniel707 is jumping the gun because the interview with the pilot definitely does not "confirm" J-20 can supercruise as it is, but the interview definitely raises the possibility I think

Supercruise isn't dictated strictly by max thrust. For example, the F-16XL could supercruise with an Al-31 class engine.

Of course, and I wasn't suggesting that.

However max thrust (dry thrust) is an important variable to consider, and if we want to ballpark the possibility of whether J-20 can supercruise or not given its current engines, dry thrust definitely needs to be considered along with everything else we know about J-20 and other aircraft that have been said to be able to supercruise over the years.
