    the difference with the F-35 is that the rafale was delayed due to political decisions (based on budget reductions), and not dassaults inability to deliver the product as it was supposed to do the rafale demonstrator (prototype if you like) flew by mid 1986, and the C prototype six years later (the M prototype a little later the same year (1991) )

    it took it about a decade to start entering active service with a couple of years standing by on political decision

    @ mrmalaya

    Airbus has been looking into flying wings, but they don’t consider that as a viable option because of the airport space limitations. They are more and more crowded and it’s difficult to fit a flying wing into that, with sufficient interfaces to embark passengers efficiently, etc…

    for a flying wing to work, you’d need to come either on top of the wing, or undereneath it, and that would require a complete redesign of airport terminals (or building specific ones), and that, all around the world, which is highly unlikely

    Some will appreciate the title of this post. Almost certain VADM Dave Venlet will.

    Bob Cox over at the Ft Worth Star Telegram has this to say about what now seems to have become annual event – specifically, the third restructure in three years of the F-35 program:

    http://blogs.star-telegram.com/sky_talk/2012/01/dod-officials-to-review-update-f-35-program-plans.html

    As Bob says, provision of this information is due in no small part to the diligence and hard work of Jason Sherman and the Team over at Inside Defense (subscription).

    Inside Defense reports that two (2) meetings of the DAB have apparantly been scheduled and, as Bob Cox says in his article:

    The outcomes from these meetings should provide yet another opportunity to calibrate (if not verify and validate) the estimates from the independent assessments made via the risk based cost modelling done by the team at Air Power Australia back in 2006:

    “flawed analysis”…. yeah sure… :rolleyes:

    he talks about the passenger version. for cargo, you can always have a ramp onboard for easy loading and unloading

    but as far as passengers go, you have to be able to embark and dismebark them efficiently (how do you park a flying wing near the terminals?), not to speak about evacuation

    aerodynamically, it is obvious that the flying wing is the best solution (most efficient), but if it is considered ok from a “operational standpoint” with all the modifications you’d have to do, that would simply mean that all the fuss about the A380 was just bs… πŸ˜€

    very low because they delayed that buy for years already and their fighters need replacement badly, if I’m not mistaken

    as for “two more weeks”, it sounds very “olegish” to me πŸ˜€

    however, one phrase from the last link

    Officials say β€œlife-cycle” maintenance costs of each plane will determine the winner of the deal.

    if they determine the winner on lifecycle costs, does that mean that the ToT packages proposed from both sides were similar?

    In such case, the rafale may have the edge there, especially if india takes into consideration the other export customers experience, like austria whose flight hour cost more than tripled from what EADS annonced them

    considering that the marines never went anywhere without the navy supporting theml in the last decades, they had no need for harriers anyway, the carrier group being not so far away, other naval assets were there, and, as far as deployment on the ground goes, the USAF was usually quite close as well, as soon as they had access to an airbase.

    Basically, they’d probably just drop the STOVL as such and the USMC would simply use a CTOL/CV version as the other services do, which would be a wise decision from operational and from budgetary PoV (for the USA, at least)

    You couldn’t say that about the Rafale program when only 30 odd examples had been built either, but I agree the programs aren’t comparable.

    you’re right on one thing: they aren’t comparable, as dassaul delivered what was asked from them, not LM and the delays in rafale program were due mainly to politicians will to reschedule orders for budgetary reasons, not dassaults inability to make the aircraft up to specs (changeable ones, besides, while LM has trouble getting just to the original ones)

    in the end, there are over 100 rafales (not “only 30 odd examples, as you incorrectly imply) in service right now which is over a third of the French total planned number, with dassault having a quite clear idea on how much profit they make out of every aircraft, so, if they say thay can make it profitable even without exports, chances are they have a clue what they are talking about… about LM, that last point still has to be proven

    So has the F-35C. 3 successful captures in fact. Despite this it failed one set of tests, obviously the conclusion therefore can and should be drawn that the aircraft is a failure…

    :rolleyes:

    just a reminder, for every take off an aircraft has try to land back at least once. if it caught the wire three times out of three tries, it’s ok. if it caught it three times out of a hundred tries it’s a failure in that domain

    That is not the issue

    not yet… if may become an issue if they increase the efforts on the parts involved, which is considered as an option

    Why interesting? If he came to say “there’s nothing to be seen yet”, why would he make any comment on rumors (started by whoows who)? Ignoring them is the best way not to give any clue to speculators to start with, plain and simple

    From Thales:

    http://www.thalesgroup.com/Portfolio/Defence/Aerospace_Product_SPECTRA/?pid=1568

    The SPECTRA system for the Rafale combat aircraft operates in electromagnetic, laser and infra-red domains. Using sophisticated techniques, such as interferometry for high precision DOA and passive ranging, digital frequency memory for signal coherency and active phased-array transmitters for maximum effectiveness and covertness, the highly advanced multi-sensors and artificial intelligence data fusion capabilities of SPECTRA provide the Rafale aircraft with the best chance to survive in harsh and lethal environments. The Rafale combat aircraft and the SPECTRA system are fully operational onboard the French Navy’s Rafale.

    Offering unique high sensitivity detection and multiple threat capability, and operating smart data fusion between multi-spectral sensors, it provides identification, location, jamming and decoying against an extensive range of electromagnetic, infra-red and laser threats.

    Additionally, SPECTRA fulfils new functions in a combat aircraft, while significantly participating in the determination of the aircraft’s tactical situation, and providing the crew with operational advantage by performing accurate threat location.

    By virtue of its fully passive situational awareness capability, SPECTRA is a major contributor to the low observability concept of Rafale.

    BTW, the DAS does provide indeed SIRTS (situation awarness IRST) and acts as a cueing sensor: the DAS will just establish the precise direction of the IR contact (no zoom) and slaves the EOTS (this one while having a minuscule FOV, can zoom at impressive ranges). The combinatrion of these 2 sensors is a deadly one.

    sounds a lot like what SPECTRA does already πŸ˜€

    one may also ask: if you apply a stronger force on the hook to keep it against the deck, how will it affect the durability of the hook and supporting system?

    more force meaning higher efforts to withstand, meaning, in return, higher fatigue and shorter lifetime for the parts involved

    Since there are already design solutions to the F-35C’s hook problem I guess this will be as big a non issue as the melting flight decks of LHDs…

    http://4.bp.blogspot.com/-snJZR7orgJk/TurXfH_aX1I/AAAAAAAABno/xOotNBWCOFI/s1600/f_35chooksideviewgraphic_566.gif

    you see, there’s another thing that bothers me about that design (the red one aka “the solution” )

    in blue, you can easily see where the arrstor wire would lay “in the hook”, as the “row” is somewhat deep in order to catch it well and stay that way.

    The red one, however has a much shallower “row” so, I wonder, even if it manages to catch the wire, once it will be pulled hard back, will the wire stay caught or will it drop out of it? When you look at videos of carrier landing, the wire behaves like a whip most of the time, with a sharp rise and then goes just into a couple ondulations somewhat, and during that second part, with such a shallow row in the hook, I have to wonder if it will stay there. an example you can see many traps here, and some are filmed from very close where you can see the cable moving very well:

    actually, what you find “strange” is how things work in real world: you develop something, test it and, if it works consider your problem solved.

    it is only in LM fantasyland that you make a nice drawing on your computer and consider the issue over before even knowing whather ot works. that’s exactly what they do in this program since the beginning and why it’s such a budgetary mess: it is called “wishful thinking”, not engineering
