    X 2 🙂

    What a rubbish argument, why do people assume that ingestion = crash ?

    probably because it ends quite often that way (not to say every time) when a big bird is ingested by a single engine fighter…

    a pigeon or a sparrow may cause just a hiccup, but something like a goose has good chances of messing the engine for good

    what’s more, they may use radar reflectors like the F-22 in order to hide their real RCS values from other participants, making the whole discussion moot

    well, to be honest (and I have no idea of the real motivations they have), no politician will ever admit he just looks to justify his previous and contested choice…

    However, if there is a transparent comparison, it may become difficult to justify a choice if it doesn’t make sense considering the data provided for comparison…

    in any case, we’ll see how it turns out. Funnily, though, they seem to have asked only to boeing and EADS, rather than making it a wide competition in order to get the best possible deal (dassault and saab may eventually find it interesting to propose something, for example…)

    to put it simply:

    denmark needs an aircraft for air policing, meaning, it has to be able to scramble and intercept an aircraft up to the airliner’s performance, over a (very!) small territory…

    that means, it needs a decent interceptor (anything supersonic on the western market (where they do their shopping) will do today).

    If they want to joint some NATO adventure somewhere far from their place, they need a NATO compatible aircraft… again, anything on the western fighter market will do just fine, be it a US product (modernized F-16, SH, F-15, F-35), or the Gripen, Rafale or Typhoon. They all are NATO compatible, and can operate together..

    From there on, it’s quite simple: they can choose whatever they want from all these depending on their amount of cash available and the options they want, the date when the thing has to be ready, delivered, etc…

    one thing that is quite laughable is that argument about russian bombers… to get to Denmark they only have to pass through or just beside several of:

    – Baltic states airspace
    – Polish airspace
    – German airspace
    – Swedish airspace
    – Norwegian airspace
    – all of them

    so, unless they use some space cruisers right out of star wars, methinks they’ll have some trouble long before getting even close to danish airspace… not to speak about the reason that may motivate Russian to go especially after Denmark (they may have much more interesting targets to attack elsewhere long before getting there)

    In basic terms, you kill people WVR by pointing your nose at them…..yes things like JHMCS/HMD muddy those waters a little, but getting into a position to employ weapons is still always the goal. The guy with more nose authority who can bring his weapons to bear quicker than anyone else will win the fight. TVC and high AoA capability are both very effective means to this end.

    it’s true, however, there’s a difference between pointing your nose while floating away as you only manage to go straight ahead (like in the 50° AoA case this all started from) and pointing your nose in a manner allowing for an efficient shot (tracking your target, turning inside it etc…)

    we’re talking about humans firing… 😉

    if you have automatic (radar) guidance, with a computer to do the calculations for a successful aim, it’s another story…

    he could shoot very accurately, but not at “9G”… again, at sucvh load factors, it’s a matter of luck rather than aim to hit something

    to be honest, chances of hitting anything with your gun at 9G are pretty much close to 0, and even lower to record it on camera, as at such G-load, your target would be somewhere below your nose (unseen on camera).

    we agree on that, the fact is that you don’t aerodynamically control your aircraft in such positions (at least, not enough to put it through any manouvers other than straight line)… the only really efficient way to manouver it is through thrust vectoring (which is how Sukhois manage their “awesome” maneuvers 😉 )

    @ djcross

    on that video, when raptor’s engines are at idle, it is basically dropping… descending, falling, call it the way you like… while one may consider it as “high AoA flying”, it’s more like a controlled stall…

    in fact, 360° AoA is 0° AoA (pretty much going ballistic… 😀 )

    considering that at 50° AoA you only have vortexes around your wings, you produce, basically, drag, and … er… drag…. and a lot of it… while your aircraft doesn’t necessarily fall like a brick (thanks to the huuuge thrust at the rear end), it can probably control its roll (meaning, avoid falling to one side) by differential moving of the tail surfaces

    Trying to do anything else than straight line would result in a serious loss of altitude (considering that even a simple roll as visible in various videos they posted, results in a significant drop)

    In this case, “remain controllable” seems more to be “doesn’t fall immediately out of the sky”. In any case, for “hopsalot”: about rafale’s limitation to 29°, during flight tests, it went up to 100° without loss of control, however, besides loosing all its speed, the use for such insane angles is non existent.., which is why the FCS was limited to “useful angles”, pure and simple

    on another hand, standing at 50° AoA is pretty much useless anyway… even for maneuvering, you’re a sitting duck if you pull any similar amount of AoA.

    The interesting thing is: what’s your lowest speed at which you can pull your maximum G and stay there (meaning, “turn in the tightest possible way”).

    a simpler way to answer would be how many F-35s have been delivered?

    How much did the program cots until now?

    make a division and you get a figure around $1bn+ per aircraft as of today..

    once the program is finished, you can calculate how high was the cost, and in any case, your figure of 120 million is “without development costs”, if you iclude these, even by the end of production, chances are that no F-35 will get below the 100 million dollars figure
