    Man the Gripen has no STR of 22.5deg/s it has one of only 20 deg/s however a turn is the result of ITR and STR, in a turn the Gripen will start with an advantage that will evaporate as the turns developes, the F-16 will start slower but will surpass the Gripen`s rate at the end.
    The end result is the parity of both designs.
    The MiG-29 will start at 28 deg/s ITR and will end up with 22-23.5 deg/s, so it will catch up fast with the Gripen and at the end will surpass it by a great margin.

    The Gripen starts at 30 deg/s ITR and finishes at 20deg/s STR.
    The Gripen has a very low yield engine compared to a F100 or AL-31 but it has relatively a small weight and size and a huge wing in proportion plus canards.

    These are realities, the Gripen more or less is on par with the Mirage 2000, F-16 and MiG-29

    For the Gripen it has to get the first look first kill at the begining of the turn, once the turns develop the advantage is on the F-16 and MiG-29 that will out turn the Gripen.

    So long turning maneouvres are not the main strength of the Gripen, the Gripen is just slightly better than an Mirage 2000

    this is not the answer i wanted. Your moving away from the subject. the subject was about weaker engine, and energybleed and efficient dynamics.
    And you are still going i circles, with claims without any real facts. just a handfull from one part of the world, stop trolling!

    Why do you think europe, china, and korea see the future in canards but US and Russia dont? Who is really stupid? Whose that doesnt understand or those that see the potential? 😉

    Europe is the only ones that really have experience of the both types (operational). Which way are they going next? It seems to go the canard-way at the moment…
    So once again you loose.

    SAAB knew the Gripen chosen configuration sacrificed STR but in general it offered a good ITR and small size using a single engine with less power than any engine used on F-16s and MiG-23s.
    .

    So as you are saying, gripen with its “weak” engine without TVC, sacificed STR over the a f-16 design, and landed on “only” at about 22deg/s STR?
    this makes no sens…
    With it weaker engine, the deltacanard, really need to be extemely efficient in turns (less bleed), not the other way around.

    Now the question is why use a canard?

    simply because you are using a delta that has lots of lift and little drag and you are using a small canard.

    Now the F-22 has a STR of 28deg/s, can do the cobra and has a Max supercruise speed Mach of 1.7, this means its tailplanes are doing a good job (The T-50 is similar).
    This proves you you can get better results with tailplanes if the designers do a good job.

    I think you are going i circles and not getting anywere. first of all 28deg/s STR (have it ever been displayed?) comes from vectored thust and to big engines, not tailed configuration.
    second, downwash or killing lift of a canard is something a have never read in any literature, so if you got sources on the subject it would be really nice.

    what a lame way to prove STRs without even considering the pilots are trying to do the best STRs or are flying the aircraft at similar weights and configuration, that is not a manual niether an air force assesment

    And the STR for the turn is still 22,5deg/sec. Buy the way, all planes are in the same position, showing of the best of its plane (all in shows, means optimized for making the turns)..
    Tejas is little of, not flying its hole envelope, but thats it!

    check what you posted it says high AoA like i am telling you

    and? Canards wins in less energy bleed and lift 😉

    Where it has demostrated the STR on videos posted here? that is not true the Gripen has a lower STR it has been writen in books and webpage

    An by the way the TWR of the F-16 is not as high as you suppose barely it is 1.1:1 nothing extraordinary or very high compared to the Gripen which is close to 1.

    360deg/16s 1.35-1.51sec= 22.5 STR= better than falcon

    What’s canard “on” and “off”?!
    Never heard of that.

    “off” is when you do mach 6 and they automaticly falls off… :rolleyes:
    Otherwise they are “on”.

    The swedish fighter already compromised more stealth by moving the canard above wing level, the Korean fighter does not, by the way Russia and the US had stealth fighters with canards but they drop them
    why?

    reasons simple the canard has more disadvantages when stealth is applied, their performance will be far more degraded

    you hve no prof of that..
    the above dont think so, and nither do i.

    with external weapons your statement is utterly wrong no eurocanard will have that carrying external weapons

    this is were tactics comes to mind

    because of an stealth patent 😎

    The T-50 will be armed with longer range BVR missiles than meteor and at 150km the T-50 will be unseen, at BVR the Rafale can not even see the F-22;)

    even? in 150km is most modern canard is unseen by another fighter. (RCS around 0,1m2)
    An S-band AESA AEW will see it in a long distance..

    Please all of these points you are claiming are not going along the latest stealth flying fighters like the T-50
    No canards and yes tailplanes and stealth

    and? whats the big scope? ever thinked about next gen stealth?

    In the future, europe, china, korea seems to go the canard way for stealth fighters… and for them, is seems to work?

    PS. and yes the designs are probably tested in RCS testing facilities..

    True, but that’s beside the point and F22 must ignite the AB to stay on M2, just like F15, so the difference will reduce considerably.

    But anyway, the point is F15 is as fast/faster than F22, no matter for how short period of time, or due whatever reasons. Period.
    It’s impossible to conduct an articulate conversation, when fundamental factors get skewed, all the time.

    if it didnt got it coatings to think about the F-22 could probably be faster..
