    So Norway’s F-35s will get the same RCS as the US ones. But if, say, Brazil or India buys F-35 they may or may not get the same RCS…

    By the time of the potential purchase, Brazil and India will be producing much better RAM materials then the current american.
    The worse thing the F-35 will bring, is make the world react to the current american technology and advantage.

    Strange that you still didn’t get it: when is loaded with weapons (internally) the F 35 is clean aerodynamically…

    No it is not!!!
    An aircraft having an internal weapons’ bay, is penalized by the extra weight of the structure, skin, and door mechanisms, which is hardly trivial, plus a slight shape compromise, from the aerodynamic ideal.
    This extra weight will be translated to the wing, which in turn is going to operate in higher A. Of course the drag in this case is less, but, this aircraft will have to carry its penalty, all the way to and back from the target(s), whistle a non stealth will be clean (real clean) half the way!

    If the internal carriage of weapons had any advantage, other then LO, then many 2nd 3rd and 4rth generation aircraft would have simply adopt it.
    Internal carriage of weapons was not discovered yesterday.

    Just because its printed doesn’t mean it’s true. :rolleyes:

    Nobody said that.
    On the contrary.
    The idea of the F-35 being a bad concept (NOT a bad design, in some aspects it is brilliant), from the first place, is a questioning I personally had since …..ever.

    But it seems that a lot of “credible” people pose the same questions, might mean something.

    Think THIS is it

    True.

    I wonder which is worse. F-35 prove to be a lemon or Carlo Kopp corect? :diablo:

    If I’m not totally wrong, those guys belong to the so called fighter mafia. And they didn’t have to say anything positive about any US fighter programme in the last 20 years.

    The possibility of all the fighter mafia guys being correct, after all, is completely absent according to you ???????????

    I didn’t find it, could you post a link ?

    Sorry I can’t

    All the same, Shame….

    Any critic to the F-35 end up in insults, some of them personal, from some of the members of this forum.

    Just a quick question, IIRC the Hellenic air force is supposed to choose a fighter sometime late this year?

    The Typhoon was a front runner till the Olympics intervened.

    Now if the ‘late this year’ decision is still on have the Greek been testing other aircraft such as the Rafale?.

    Cheers

    Unofficially the Rafale is out…

    The candidates are the EF, F-16B60, and the Super Horror.

    I wonder if DAS detects inbound missiles when their engines and turned off, either because they burned their fuel or because some of them have of throtable ramjets…

    I suggest the doctor thesis “Signal Processing for Airborne Bistatic Radar” from Kian Pin Ong

    Then take a look in the Acknowledgements. 😉

    So Dr Juergen Kruse, of EADS, is already working on energy distribution of stealth aircraft?

    Except they say that the “TARGET DATA” was received through MIDS. they didn’t say the plane were in bistatic arrangement nor that they were just linked via MIDS.

    And if they were in bistatic arrangement they’d make it very clear… and would brag about it all over the place.

    Nic

    But of course, this is what they say, and they are very positive about that.

    But as you very well know, in military technology, nobody speaks the complete truth.

    Is your monstatic RCS low then is your bistatic RCS high, you can only eat a cake one time!

    The laws of physics maintain that energy must be conserved. If the monostatic RCS is reduced by shaping, the incident energy must be distributed elsewhere. As such, the target signature is increased at some or all bistatic angles!

    So I guess you agree with what I am saying, or not?

    If the radar was in passive ‘receive’ mode, there wouldn’t be the need to receive target data through MIDS obviously

    Not that obviously, Nic.

    If the 2 EFs were forming a bistatic arrangement, MIDS data exchange would still be necessary, but different.

    For the passive radar to extract accurate info, it still needs
    a. The exact position of the “shooting” radar,
    b. the shooting angle,
    c. the shooting timing and
    d. the exact waveform.

    When reading such a press release, one should take note of all the significant words.

    E.g. “unique AMRAAM firing”.

    “The objective of the testing was to fire the AMRAAM missile from a Eurofighter Typhoon whilst its radar was in passive mode and thus “invisible” for Electronic Support Measures (ESM) Systems. The necessary target data for the missile was acquired by the radar of a second Eurofighter Typhoon and transmitted using the Multi Functional Information Distribution System (MIDS). Both aircraft were separated by quite a distance in range.”

    “IPA4 led the trial as the “firer”, while IPA5 as the “cooperator” illuminated the target with its radar active. This trial is the first known testing of its kind”

    Now, what exactly is it saying? Is it saying it is the first AMRAAM firing of this kind? The first radar-guided missile firing of this kind? Or the first missile firing of this kind? And what is meant by “of its kind”? One fighter, with its radar not emitting, fires a missile using data from another fighter? Or a non-emitting fighter fires using data from another source – any source? Is the fact that the aircraft which fired the missile was not emitting the significant claim?

    Unfortunately, it’s rather imprecise, & I’m not sure what’s actually being claimed as a first.

    Here is a good question.

    When quoting that the firing aircraft radar was in “passive” mode, what exactly does he mean?:confused:

    The most probable answer would be that that radar was switched off, not emitting not receiving. Right?

    But then again, why call it a “passive” radar?
    And of course, why even claim that was something extraordinary, whatsoever?????

    Could it be, that both aircraft were forming some kind of bistatic radar arrangement:dev2:, one emitting (the further away) and the other (closest to the threat) receiving?

    Things get just a little bit more interesting, if one takes account one presentation for the Norwegian AF some years ago.
    Nobody of us was present to listen to what was told,
    but,
    the RNoAF uploaded the slide show of the presentation, on the net, and there was, a rather peculiar slide:
    http://img268.imageshack.us/img268/336/879798.th.jpg

    Aha, The passive radar again? Could it be a coincidence?

    And against what? The mighty stealthy, and upcoming F-35. Hmmmmmm
    Getting interesting, right?

    And now here is the best part:
    EADS, and ch Merkel are doing everything possible to secure the Greek order.
    That is for 40 (+20?) Eurofighters, no less.
    From their presentations in the Greek media, their stress for providing a credible anti-stealth solution was more then obvious**.

    The Hellenic dep. of defense has ordered a study, from the KEAT (part of EPA, center of air tactics*) to evaluate whether the EF could fight and counter the F-35T. The study is due this summer, just prior of the final (possibly) decision for the new fighter purchase….

    …..and next to this Unique AMRAAM Firing.

    Just food for thought

    Here you can see how the obsolete Typhoon and the futuristic F-35 will fight Su-35s and who will survive and who will die.

    …and of Hollywood quality, no less…:D:D:D

    due to work, I didnt log in for a couple of days
    this forum was an aviation forum, and this thread a euroighter one.

    What happened?
