J-20 5th Gen Fighter Thread VI

[sequ]

If it is indeed related to a carrier-variant, could it be that they are just using one aircraft more or less as it is similar as once one of the original J-11B prototypes was tested?

Could you tell me/us when this test took place and why?

 

[Deino]

Allegedly prior to 2010 in preparation of the tests off the ski-ramp at Xi'an-Yanliang with the true J-15, which then took place on 6. May 2010.

 

[Tirdent]

Yes, for ski-jump tests a fully beefed-up carrier-capable airframe is not necessary (the USSR also used Su-27 prototypes before the first Su-33s were available). Even approach trials at sea would be conceivable (pilot field of view trials with Rafale A & Foch), but no touch downs or even arrested landings.

Could someone translate?

It looks like either the 2011 or 2012 prototype because of the pitot tube.

Hi all,

I was looking at pictures of the J-20 and realised that the aileron actuators are 'slanted' relative to the longitudinal axis in the production models. They were 'parallel' in the early prototypes.
Anyone know what the reason could be?

And could these bumps be eliminated in the future similar to the FC-31's fully flush design?

For comparison to other aircraft;

Those sources could be wrong or only partly true and ignored the fact J-20 is still in competition against FC-31 for carrier borne fighter. Unless they're already testing upgraded engines and/or frames for J-20, and this cartoon is revealing of actual program, they wouldn't be painting those markers. CAC may have realised they can make J-20 carrier ready with some effort but still achieve this around the same time SAC can get FC-31 completed. J-20 program is further ahead after all.

I'm sorry, are there sources suggesting that the J-20 design is still being considered? So far, all of the credible posters and insiders have heavily hinted at a FC-31-derived design with no mention of a J-20 competitor.

By the way, the appearance of calibration markers (aka "crash test dummy logos") does not imply that the J-20 is being adapted for carrier operations in any way.

Wow, impressed by how smooth J-31's underbelly is! It's the only design here without bumps or visible aileron actuators...

According to PB19980515 the future J-XY (which he heavily suggested is derived from the FC-31) has the lowest RCS of all Chinese fighter aircraft.

I kinda assumed that would be true. It's smaller than J-20 and designed more recently with Chinese advances. I expect everything moving forward to be superior (unless China goes for another more modern budget fighter designed on JF-17 philosophy). I'd be surprised if the PLAN would tolerate back-stepping in performance even if it was a different design institute.

Unless SAC pulls another J-16 episode, it will be the PLANAF and suppliers of subsystems that will ultimately determine the capabilities of the fighter. I fully expect the J-XY to match the capabilities of the J-20 and then some, similar to how the F-35 brings new things to the table that the F-22 wasn't able to before.
