    My professional involvement with MH17 started within hours of the shoot-down, and I got a lot closer to it than the viewpoint from my armchair.

    Yet you’ve still arrived at some very basic errors of judgement. Case in point – no evidence of high altitude SAM. Whereas all aviation forums globally reached the opposite conclusion immediately after the transport plane shoot down. Sometimes you don’t need the title of expert, you just need commonsense.

    ‘Armchair’ is a figure of speech. You weren’t among those being bombed and rocketed by aircraft, therefore you are judging from the equivalent of an armchair.

    Wrong — it’s the Gripen EWS that is underrated… 🙂

    Nope. If Spectra was anywhere near as good as claimed, it would have scored a comfortable 9 for EW. Gripen claims no active cancellation or any of the exaggerated crap that the Rafale does and yet gave a similar result. Face facts.

    weight is only remotely related to speed, unlike acceleration & turn performance, ,
    as in, lift induced drag is only part of total drag that will determine top speed at a given thrust,
    when drag equals thrust is the point when it stop accelerate, a 10% increase in lift drag is not a 10% increase in total drag,
    the higher the speed, the less percentage of total drag is made up of lift drag
    there is no reason to assume SC below M1.2

    The brochure says M1.1 only for Gripen E, which is effectively not really a supercruise capability.

    That document says the speed was a strong point for the Eurofighter.. It never speaks about speed of Rafale as they put forward other strong points that look obviously more important to them: to put it simply: you have zero data to say anything about Rafale’s speed except that with what it has (whatever that may be) it was able to fulfill all the missions required

    So they only mentioned it for the Eurofighter and deliberately ignored the Rafale having the same capability and then gave it 7 instead of 9 for performance?

    It’s very clear that there are a number of Rafale fanbois here.

    And in Eastern Ukraine on 17 July 2014, an idiot was prepared to order weapon release, and 283 innocent people died as a result. Given that the JIT now has the names of around 100 persons of interest to their investigation, the idiot in question will probably have to shelter in Russia for the rest of his life, or face prosecution in a West European court.

    As always, Jonesy, your postings bring the discussion down to earth. A refreshing change from political rants, and people such as Starfish Prime who persist in asking me questions that the official reports on MH17 have already answered.

    If the report can’t simply admit that after the military transport was shot down, it was clear high altitude SAMs were operating, then it lacks even the beginnings of honesty. And if it fails to acknowledge that diverting over a war zone at the last minute is dangerous, then that is also dishonest.

    Try put yourself in the position of someone subject to air attack. All very well judging from the armchair.

    I am truly staggered at this….I never expected to see Russian stupidity trying to hide behind American stupidity. Its the behaviour of the school playground “well he did it first!!!”. How old are you people?.

    Its war tensions are high…..thats why professional services HAVE RoE’s in the first place!. In 82 the RN taskforce on transit was getting regular visits by an Argentine AF B707. After crossing a specific point RoE was changed to permit a shootdown. A contact came in on the same profile some days later, but, it was realised that the contact was in or close to an established civvy air lane so a hold fire order was issued. Later visident showed that it was a VARIG DC10. Unidentified planes aren’t ‘liable to being shot down’ unless theres an idiot commanding the weapon release.

    So are the USN and USAF complete idiots then?

    After the transport plane was shot down the Ukrainian ATC shouldn’t have had military sorties and civilian flights in the same area period, end of story. And all the airlines with any sense, were avoiding Ukraine during the same period.

    Also, quit acting like this is the first ever case of collateral damage in the whole of military history.

    Playing devil’s advocate here, (as I don’t believe in active stealth- yet), the French wouldn’t turn these systems on during Red Flag, would they? Just as the US won’t use the full extent of their systems capabilities …just in case.

    If it worked as stated, you wouldn’t even know it was on.

    Not as per most here. Is there anyone here that is buying your argument?

    Don’t care, there are people here who think RWR can use monopulse and conical scanning. It’s the same bunch of Rafale fanbois arguing on every thread, so who cares? The link says the ultimate version will be GaN and there is no version after Radar 2. We’ve also seen people argue it’s the same radar as the Euro one, also proven false. We also know GaN will be mature before 2020. If it was the same radar, they could put it on in 2018 and add the extra functionality in a software update later.

    Wish we could have Scorpion82 come in and settle this for good.

    It’s settled for good. Radar 2 is coming in 2021. It’s a well established fact that 1 and 1+ are GaAs and 2 is GaN. Show me a radar 3 if you believe otherwise.

    LOL it’s even more amazing then that wheras the Rafale is a mature, well polished multirole a/c with a production AESA the Typhoon is struggling with numerous issues of whic lack of AESA is but one. It is actually you who choose to believe in the mythical GaN because it seems to suit you.

    No, I choose to believe it because it’s stated so.

    It very clearly is not the same radar at all.

    Typhoon development has been held back by debt-ridden and unwilling partner nations.

    So what is the real difference between intake ram and spliter plate? aren’t they both supposed to slow air down?

    A ramp system can be fixed or variable. The idea of using a ramp stems from the fact it can produce an oblique shock rather the normal shock seen with pitot intakes. The oblique shock occurs less total pressure losses and is hence more efficient. Now a single oblique shock followed by a normal is optimal for low supersonic speeds, but nearer M2.0, it becomes desirable to have more than one oblique shock prior to the normal shock, hence variable geometry comes in. At M1.2 it makes pretty much zero difference, and despite the fixed geometry ramp, the Typhoon still manages M2.35, which is more than the MiG-29.

    The splitter plate is simply the thing separating the intake to each engine. All explained here.

    With all that “active stealth”, it’s funny that you never hear of them ruling the skies at Red Flag :stupid:

    And why they only finished 0.5 ahead of a Gripen’s EW in Swiss Eval.

    Spectra is good but it’s incredibly overrated nonetheless. Marketing it as substitute stealth is grossly misrepresentative.

    Not my bad if you do not understand what iFi mother company electronicians wrote. He wrote the system was designed using active cancellation BECAUSE a linear regulator would NOT have fit. And after you pitifully attempt to disclaim “explaining” (sorry copy pasting wikipedia without sourcing your comment) how works what they DID NOT use to say it is not active cancellation… Of course a linear regulator isn’t… And they did not build one!
    How typical from you…
    Which acronym did i use? Cite one? Lying again…
    And you did not write down any definition, you simply copied wikipedia attempting to explain something you do not comprehend. (otherwise you would have been able to explain it by yourself). How would you the heck know who i was talking to at Abingdon Music Research? You claim it was a PR? Prove it! (your way to act usually no)? I

    Of course, i guess you know their stuff better than the company involved… And i cite what i want to cite, it is not an anonymous armchair expert in wikipedia that will dictate which part of conversations i have i will -or not- cite.

    Fairly well explained by the company here. Nothing to do with wave interference as electric parasitic noise has nothing to do with radioelectric waves. Still the active cancellation principle is applied (although not using half wavelength displaced signal as it would for radar waves cancellation). NVM…

    By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. ANC+® is the perfect ‘antidote’ for power supply noise, the bane of USB audio.
    ANC+(3)
    With ANC+® the power line is filtered for audio band and RF noise. The measured noise floor of 0.1uV (0.0000001V) is at the measurement limit of what even the most sophisticated Audio Precision equipment is capable of.

    Measured noise drops by 100 times or 40dB in comparison to the common noise filters.

    Sonically, the background and inner resolution to recordings is brought to the fore and no longer hidden. Sonics are much smoother, just like how good analogue should be. Nothing comes close.

    Pathetic again…

    Comical marketing stunt. Not even a remotely similar application.

    For the record, I bought a noise cancelling headset. Returned it immediately, stupid thing cancels half the frequency in the actual music too.

    depends, math suggest gripen E out ranges EF significantly and rafale slightly in A2A configuration,
    but will be inferior to both with heavy loads.

    on the rafale M1.4 SC, i dont buy it, simple as that, its a repeated myth IMO,
    i would think it can do around M1.2

    And here’s proof. In Swiss evals the Typhoon was praised for its supercruise, attained M1.4 with whatever load (M1.5 according to Austrians). Rafale was not. Enough said.

    I like Gripen but both of these things are wrong.

    I’ll second that. Check out the very low TWR.
