J-20 turning versus Rafale and Eurocanards, is J-20 a real air superiority?

    If you look at this Rafale turning you can see it barely deflects the canards, in my opinion the difference is related to the light weight configuration the Rafale is flying (low wing loading) and the difference in static stability.

    I think that difference in static stability, reflects a difference in role, as the paper originally claimed



    But the Chinese airplane appears to
    have the center of gravity position somewhere
    at MAC’s edge. It is fairly strange
    for a maneuverable fighter, since balancing
    of the aerodynamic forces and
    the gravity will require relatively high deflection
    of the control surfaces — canards
    in the J-20’s case. Should this airplane try
    to execute high-G maneuvers at subsonic
    speeds, the deflection of the canards could
    be a limitation.

    This was predicted a year ago, in my opinion J-20 is indeed a striker interceptor


    In our view the Chinese designers optimized
    their new jet for M=1.3–1.6.constructed
    Here comes the clue: the J-20 is a missile
    launching platform able to evade enemy
    interceptors by high cruise speed.
    The J-20 may prove a good interceptor, —
    very possibly. But its main task seems to
    be anti-shipping: firing missiles at enemy
    warships while denying their air defense
    cover.

    Compare with J-20 at 4:20 minute, you can see the J-20 is deflecting a lot its canards, reflecting the difference in static stability and role according to the paper

    There were rumors that they develop another stealth fighter for air superiority, but how likely is it that they develop 2 heavy class stealth fighters? If J20 would be meant for interception and strikes only, wouldn't it be more logical to develop it in the medium class, to complement it later with a heavy class air superioirty fighter? The current mix in PLAAF shows heavy class twin engine Flanker versions, with medium class single engine J10s, so they have a clear distinction like US forces as well.

    J20 to me would be an excellent BVR strike aircraft.

    Maybe they are planning to have something like MiG 31 and Su-27 series of Russia.

    I think the logic would be as follows
    J-10 single engined,
    This will be the backbone of the PLAAF, this will be maid of all works and will be in big numbers, it will be something like MiG-21 for IAF but much more dynamic role. It is as capable as Gripen.

    Su-30 MKK: Twin engined
    Medium Heavy class, this is the present premium Multi role combat aircraft, It will handle air superiority, strike roles.

    J-11 : Twin engined (chinese version of Su-30 MK)
    Medium Heavy class, this is the present premium Multi role combat aircraft, It will handle air superiority, strike roles.

    J-20: Twin engined
    It will be the premium plane that will be the top of the line plane, and thus push the planes like Su-30 MKK and J-11 to lower rung from their top of the line to middle of the line.
    It maybe used like how America uses F-22 mainly over its mainland to protect its borders and to avoid as much as possible falling of their top technology. This plane maybe accompanied by other planes like Su-30 MKK where J-20 would make the initial strikes and then let the other planes follow its lead
