    Like it or not, F-35 will dominate the international fighter market, just as what has been achieved by F-16.

    A 13 TM aircraft with a completely new engine, dominating the market?..a program that is still in development, and nobody already knows if will fare well?

    Europeans won’t buy a lot of them, is too heavy for them, what’s next, Turkey? how many will be bought?

    If the F-35 would weigh 9-10 tons, and would share it engine with another aircraft, with the US industrial infrastructure, then yes, it would dominate the market, i don’t know if the program will or not be a success, but i’m ready to bet this program is not a F-16 reincarnation.

    This aircraft is not a ‘western Mig-21’ (aka F-16), is a complex plane full of ridiculous over engineering, I’m sorry to burst your fantastic bubble…but this design won’t achieve such success.

    Expect countries getting out of the program, and a lot of order cuts, after we see the final product.

    It success will be comparable with the F-18 at best..if it ends successfully

    This aircraft is more complex and heavy than a F-15…by a long shot…and you come here saying it will be a F-16v2…keep on dreaming Toan…it will be a harsh awaking.

    Video or marketing video of NETRA, seen a few of these types of UAVs around now. Should be good for coin ops.

    One that i do wonder is if the video feed can be hacked into. The militants have been doing that in Afghanistan and Iraq apparently.

    This is a interesting, wonder why they did place the propellers beneath, and not on top, it seems a bit over complex, but i think there are reasons for such unconventional design.

    ******

    I might understand it better now…these are electric motors…so a single electric motor could be too heavy..so they went with 4 lighter ones, i don’t know, any better insight?

    Why not just wait and see?..I don’t get all this histeria..

    People are fighting here for the date of deployement..some say in 3 years, some say in 5 years…IMO the program is not mature enough to predict a defined date…could be in 3 years ….or 50 years…or never…

    The program is facing problems, who knows what is going on.

    Mr. Hilton, i really respect your contributions in this board, but i think both of you (including the pcfem kid) don’t understand what I’m trying to say :), is irrelevant anyways..

    There is a reliable data over the DSI thingie? as far i understand it did not increase the F-16 mach development, nor did a great deal..only thing we have is the LM claim of the M2 ‘great feat’, but is there something more specific?

    Don’t confuse JSF’s inlet installation with F16’s and both won’t do the same, although the inlet shape is similar.

    No, they are not 🙂 ….i won’t go further, i will just wait and see..but both intakes, and specially the ‘cones’ are not the same 🙂

    pfcem, you gave me a good laugh..

    **********

    Again,the bump acts as a variable ramp in a fixed position, remains to be seen in which position is it, but given that there is no any requirement for the F35 to fly over or near M2 and probably does not have the engine to do so, then i would assume is for a max M1.6 range.

    I don’t understand why people are so obsessed with the M1.6+ performance, there is no sign, no evidence no nothing for for this capability…I’m not a F35 critic, somehow i dislike all the people bashing a program in it early states…as least is not overhyped as a 5ton overweight failure wrapped on shinny PR paperbag…but the LM fanbase is annoying as well…

    f-35 “Sparky”

    What? more secrets?? more ‘classified’ (read failure design goals report) garbage? 😀

    F-35’s case, the inlets aren’t the single point of failure limiting

    Top speed is not the sole factor for engine’s performance, acceleration, maintenance, stalling, etc are important as well, and the inlet does have a influence there, for example.

    An inlet coud be designed to achieve M2, but it acceleration from M1.1 to M1.5 is lower than from M1.5 to M1.7, another inlet designed for M1.5, with better acceleration at M1.1 to M1.5…for maneuvering the stalling probability could be lower at M1.5 than M1.2, the lost of thrust at X AoA should be A at M1.3 and B at M0.8, etc, etc, etc…

    What it means is that the plane’s top speed isn’t limited by the inlets.

    Is still limited, because to achieve higher ranges of speed you need a different shape, so is your choice

    1) dissemble the ‘DSI’ stuffing another ‘DSI’ with different shape

    2) Install variable inlet

    Let’s put it clearer since you are trying to sneak into arguments to believe your fairy tales

    And engine that is not producing significantly more thrust after M1.3 will produce thrust to M1.5 with a special designed inlet for the M1.3-1.5 ranges (which is the DSI thingie)

    The F-35 might be designed for these parameters, while other planes ‘DSI’s could be designed for other parameters.

    Ok , no problem, then the range could be M1.3 to m1.5 for the F-35..according with the requirements, with a max speed of M1.6, and for the F-16 was probably M1.7-M1.9 with max speed M2..

    The point is that having this inlet means nothing.

    I don’t get why all the fuss over this ‘diverted inlet’ stuff..is a fixed inlet for certain speeds, is not a magical solution that some guys think..

    Now at which speed it is optimized? we don’t really know, we can go through a long discussion about this…is the experimental fixed inlet of the F-16 optimized for M2?, but bad for M1.5?, is the F-35 inlet optimized for M1.6?..but a disaster for M1.4-M2?? who knows…

    Let’s remember that Boeing went with a variable inlet for the x-32, and Lockheed went with this diverted inlet thingy (a nice/cool name -so typical in the US industry- for a faired FIXED inlet optimized for certain speed) after their experiences with the magical plasma-coil-alien F22’s inlets….:D

    but understand that the damage was done by an under-the-keel explosion from someones heavyweight torpedo.

    This is the problem of perception in this whole incident

    The torpedo found is not a real evidence

    The analysis over the damaged ship can be taken as evidence.

    The expert is saying the accident was caused by a collision, not by a explosion.

    The ship did not detect any torpedo launching.

    But people will still believe that it was a torpedo, why?, just because they ‘found’ (read seed) a torpedo nearby?

    US subs have been involved in collisions under ‘shallow’ waters, so is not impossible.

    The comment about a lack of scorching on ship internals and bodies is indicative of the lack of comprehension by the writer here.

    A US Navy submarine collide with the ship, and the SK authorities used it to troll the north.

    ever heard of ejector nozzles? seems no

    it’s your problem – it’s just seems that your something-meter has fault due to the lack of education

    I really don’t understand your reply..regarding my original post, are you saying the exhaust transverse area is controlled with the surrounding flow?, read again my post, and answer it.

    If so, then i guess the exhaust wont need movable parts?

    I don’t think you really understand it.

    A bit hard to believe, i can’t see how the exhaust flow could be controlled , unless the inner pads are movable.

    One can see where the cooling for the exhaust comes from… (no, it does not come from the compressor stages)

    My skeptic-meter is 9 on a scale of 10 😀

    Really?!

    Just a blind believer will take that data as granted. Some clean prototypes may have reached that peak values, but a Yak-28P with two R-98 to be a real interceptor will not. 😉

    You missed the point. In real combat a pilot will not care about peace-time limitations

    I really don’t care about this, I’m not here for a cold war macho contest.

    This is applied for every plane as well, with enough starting speed and height a Mig-23 can outurn a F-15, so what?

    The point here is the airframe limitations, and the probability for a fatal failures.
