    I know the N001VE could track 2, and the export version (designated N001?) only 1.
    lol, they really need to catch up with the west. american radars can track up to 10-12 targets now, maybe more right?

    N001 could track 10 targets, but only engage 1 (2 on later versions) at once.

    Zhuk family radars tracks 10-30 targets and engage 2-8 at once, depending on the exact model. Basic Zhuk is roughly on a par with the original APG-65.

    Also they look cool like flying saucers…. 😉

    Blue Vixen is a pretty decent radar which has had AMRAAM capability for ages. India should buy the Sea Harrier FA2s off Britain in 2006 when the UK retires them.

    Huh? They went from mildly complicated to extremely complicated because they couldn’t make the easier version work? And what do you think the AL-41 nozzles are lined with? Ceramic tiles.

    Sean, the problem with the square 2D nozzles is the asymmetrical distribution of loads. A circular nozzle is much better in this respect. The F-22’s nozzles are made of some fairly exotic materials in order to withstand the stresses imposed by the rectangular shape. You remember the size of the metal 2D nozzles on that test Su-27, right?

    The required materials technology to make square nozzles that weren’t hugely bulky wasn’t available, so they went with a circular design, with the structure made in metal. The ceramic tiles aren’t load bearing.

    “Ataka” is a modernised version of the “Shturm”. I expect they got a pile of older “Shurm” cheap to shoot at targets, with the longer range and bigger warhead “Ataka” for real warfare.

    However, it is possible that- if your calculations are correct- this radar is actually intended for the J-11.

    Rough translation:

    Chinese fighter plane owlet dragon two will stand by waiting for orders end of the month as soon as flies flushes the day chart
    2004-04-01 08:47:42

    The morning paper news (Reporter Meng the plum intern Yang Sichuan) last September flew “owlet dragon” the fighter plane also to have 3 twin brothers. Yesterday, reporter obtained the accurate news from the related channel, “owlet dragon two” the fighter plane as soon as will fly in the end of this month flushes the day. Although “owlet dragon two” and “owlet dragon” is twin brothers, but airplane internal disposition actually each has his good points, therefore this “owlet dragon two” the heaven next step will operate to the owlet dragon fighter plane the vital role.

    Owlet Long Yuan is a quadruplet

    The first batch “the owlet dragon” altogether has 4, they completely are “outside does not marry” the testing aircraft, truly will sell “the commodity” to the market machine is two years later matter. This batch “owlet dragon” although the semblance is similar, but each airplane internal disposition each has his good points. “The disposition is different mainly is for test the owlet dragon overall performance. ‘ Owlet dragon two ‘ the trial flying general further consummates the owlet dragon series type the function.” Becomes flies the technology center experiment department person in charge to say.

    “Three” special-purpose to experiment

    Enters flies the group static, the intensity experiment center, then saw the quilt “ties hands” hangs in the midair “the owlet dragon”, on its body like the scale pastes the full adhesive tape, pulls the full thick rope, is connecting under the organism hydraulic pressure. Several dozens staff methodically are bustling about.

    “This owlet dragon airplane specially performs the static experiment, it cannot ascend the sky the movement.” This is “owlet dragon three”, other “owlet dragon four” are a model. Becomes flies the technology center experiment department staff to say that, “The static experiment is front when each airplane test flight one of indispensable working procedures, the owlet dragon series each airplane will ascend the sky all uses this airplane to perform the static experiment, therefore it will have continuously to achieve the retirement to be able to dismount the whole body ‘ the military ‘.”

    “Owlet dragon two” stand by waiting for orders

    Already entered finally tested the stage “owlet dragon two” already to enter the hangar to await orders. “02” the right nose writes China to name “Fc-1” marking, left side is the overseas naming “Jf-17” and this country air force’s marking. This direct-viewing expressed it “the international background”.

    According to becomes flies company vice- chief engineer to lead to face the forest the understanding, the Fc-1 meaning is “Chinese fighter aircraft” (Fighter China No.1); A J meaning “Join”, Italy is the union development, another meaning is it stems from China “to annihilate” the series, but “F- 17” “indicated hoped it can surpass the American fighter aircraft ‘ F-16 ‘”.

    Although “owlet dragon two” in the contour also appeared very disorderly, but it slightly downward searches the incisive nose, the line smooth fuselage, still caused the entire airplane to present one kind of aggression.

    Guys, the leading Russian “Stealth” research institute have said that plasma stealth as an external “shield” is impractical. They are looking at using plasma technology as a switchable “shroud” for the radar- you have a radar-transparent container filled with gas in front of the radar, which can be quickly switched on and off. When its on, the gas becomes plasma and absorbs/deflects the radar signals. When you want to transmit yourself, you turn it off momentarily.

    If the leading Stealth researchers in Russia think its impractical, I’d tend to agree with them.

    Yes, of course… the Russians can’t design an AESA radar… Have you ever seen the radars they use for their current SAMs?

    Of course they can design AESA… they just haven’t got a fighter radar sized one they can put in a plane. The Radars used for the S-300 and S-300V are bigger than the phased array antennas used on AEGIS cruisers…

    Well thats exactly what you said, Garry.

    I’ve seen the SAM radars, and they are passive phased array. Just like Zaslon.

    That is absolutely irrelevant to whether they can design and build an AESA radar. Its totally different technology.

    I am sure Phazotron and NIIP could design an AESA, they are just starting from scratch in this field where the US has been working over a decade.

    Its scaled to fit. It might not be exactly the right size, but the proportions (antenna size to overall size of radome) are what I was showing. You could use a different planar array radar and the results would be similar.

    Heres a pic showing a MiG-29 Zhuk-M installation grafted onto the J-10. This shows you how measuring the “outside diameter” of the radome doesn’t give you the diameter of the radar.

    Well, none of the S-300 associated radars I have seen have been actively scanned phased arrays- they are all passive.

    Which radar is AESA?

    The intended production version had different intakes, more similar to this test model below, cranked delta wing, and would generally have been “cleaner” in appearance.

    The Berkut’s RCS was cut by a factor of 10 from the initial design by TsNII (they also reduced the Tu-160s RCS by a factor of 6 with RAM in the intakes and other minor measures- check out pictures and you can see easily these modifications)

    Erm well- the composites used in the MiG-29 failed badly and were replaced by metal.

    The Su-27 used practically no composites.

    The 2D nozzles for AL-41 were abandoned because the Russians couldn’t make the needed high temperature composite/ceramic, and reverted to a 3D metal nozzle.

    Oh, and the Russians recently commented how working with HAL (India) was good because HAL was up to speed on modern composite technology.
