    Even if you’re not sometimes it’s interesting to see the stuff that has been attempted over the years. Many times things that seem revolutionary today end up being something that was looked at 40 years ago but was limited by the materials or analytical capability of the day and put on a shelf somewhere.

    I know i have visited this site, one which is quiet interesting for the reasons you mentioned, but i am much more interested in collecting archives because of the high value of the informations one can find in them.

    Best example i can give you is that i have managed a few years ago to put my hands on CdG’s dimentioned plans (Not detailed design that is!!!) and that from the time it was in service, such official doc was totaly forbiden for publication…

    I have used it for a 3D model importable as add-on to Jane’s F/A 18 sim, didn’t need much for the Rafale i know it quiet well though…

    This is valid for most programmes and once an aircraft is in service, the Security and Commercial guys takes over, we got the bulls and the dark instead of interesting datas and comments…

    So if one want to know more about F-35 NOW is the right time to dig it…

    There is a huge amount of money being poured into propulsion research in the US but where is the money for airframe design?

    Very interesting point you made there..

    There is a fair amount of it (SEE DRYDEN/NASA one of the best sources in know of) but overal the US engine manufacturers had a better time.

    In France for example it have been (nearly) the opposite and Dassault’s designs reflect this very well, not that they didn’t have their little problems (with the loss of the prototype Mirage F1 due to explosive flutter of the horizontal elevator), but generaly their aerodynamicists have been on top of the rest by necessity, they always had to compensate for “traditionaly” weaker engines…

    Something else, The US manufacturers have always been quiet conventional in their approach, they try things but tend to stick to what they realy know and most designs are more of a conventional type even if there were delta-canard configurations considered for both the ATF and JSF at some point…

    For the story, it too the F-106 (or F-102 i can’t remember) to become a target drone for the designers to realise how much Gs it could pull…

    Why is that the US didn’t pursue further their Delta designs and still use a croped delta plan for F-22?

    This is ridiculous, the statements are perfectly clear, the Taranis is both a UCAV technology demonstrator and a UCAV demonstrator. It has weapons bays already integrated, and if the demonstration programme is successful, the Taranis has the potential to become a UCAV. The same is true of the X-47B

    Sorry my friend, what is ridiculous is to pretend that a single non-officlial (and notoriously inacurate) source make of it an UCAV when MoD programe goal statment cleraly indicates it only will be emulating weapon release.

    BTW these goals also indicates OTHER role for the TDP; Weapon release, REAL attack of targets as well as demonstration of weapon systems or real attack capabilties are NOT listed at any time.

    Considering the COST of developing a stealth internal weapon BAY (roughly 1/4th of nEUROn budget), in comparison to that of the Taranis TDP, EVEN taking into acount the much more intensive use on COTS and existing technologies from previous BAe UAVs, you’re welcome to EXPLAIN to the rest of us what would make “Emulation” of an attack more cost-effective than droping the load and make sure the whole thing does what it says on the box? 😀

    Please, MoD definition of UCAV is also there for everyone to SEE, Taranis is an UAV demonstrating UCAV technologies and will be unarmed, the REAL UK UCAV is still planned (perhaps if you’re lucky with economics you’ll see it) and is BTW planned for INTERCONTINENTAL strike capabilties in mind.

    My guess is that it is clearly designed not only to keep up with the rest of Europe but also as a technologic leverage for US collaboration; a technology demonstrator is expansive, a real UCAV is simply unrealistic for the UK on its own even more so NOW (expecialy one with intercontinental range), expect a collaborative programme with the US (or EU country, Germany coming top of the “possible” list) instead.

    Now since you guys keep at it PLEASE prove me wrong then and show us any form of Official stament saying it posses a weapon bay and will be droping weapon as part of its demonstrative goals. I’m waiting.

    =21AnkushONLY OTHER CUSTOMER, AdlA has ordered..

    You forgot Marine Nationale… 😎

    besides, I don’t understand where the attitude comes from when the Rafale has failed to secure a single export order so many years since its induction.

    Perhaps they are tired to participate to tenders which have only for results to boost US aircrafts sales? 😀

    Rafale will export in due time, with a 30 years+ service life and 7.000 flight hours guaratee from Dassault (Maximum structural load WAY abvove international stadards at 1.90) it is still early days and the aircraft have to see a litle more technologic growth too after F3 standard.

    Don’t forget that the programme was unfunded (therfore iddle) for so many years it is actualy laughable, but i personaly considers this as a blessing in disguise because there aren’t that many in French forces service to upgrade with AESA, M88, MIDS NG, OSF NG etc, so the overal cost of doing it EVEN without any export (YET) is STILL sustainable which isn’t the case of some concurents.

    Aircraft developement time have increased dramaticaly since the time of the F1s and Dassault/GIE have their sight clearly on the F-35 as the main technologic concurent.

    Wait and see. 😎

    Will these be the only Rafales wired operationally able to carry ASMP-A? Or will it be a simple switch with nother squadrons machine if a Rafale goes tech?

    Ultimately ALL Rafales are planned ot be put to F3 standard, right now only the F3 can accomodate the ASMP.

    59k ft is the upper limit of operational ceiling,

    = NO my friend it IS the Operational altitude and the 2000 for example is well KNOWN to have fabulous acceleration and reaches its TOP Mach at 37.000ft+ the fastest from subsonic speed; precisely because it was DESIGNED for it.

    Otherwise SAID; Dassault, the Top AdA squadron, MN knows their ABC.

    YOU on the other hand insist into refusing to admit these FACTS:

    1) You are WRONG.

    2) You still dont KNOW what you’re tralking about.

    On purpose during an intercept of a high flying target for example they will do so, but not on a regulare base.

    = NO my friend it IS the Operational altitude and the 2000 for example is well KNOWN to have fabulous acceleration and reaches its TOP Mach 2.2 at 59.054ft Operational ceilling the fastest precisely because it was DESIGNED for it.

    = BEST performance for the Mirage 2000C (D/A) M53-5 was obtained only at slightly lower altitude i.e. 57.500ft.

    = And Yes they regularly TRAIN to fly and FIGHT at these altitudes since it IS the role for which they are OPTIMISED and the threat (Mig 25/31) doesn’t wait for Mr Scorpion agreement to cross borders or for the AdA/MN pilots to be ready, they need quiet an intensive and regular training for role.

    These French fighter ALWAYS were designed for interception at the tropopause by requierement since the Mirage III and this means best performances at <> 58,080 ft; the two 5F squadron are well trained at high-altitude interception because it IS their primary role…

    They trained to do just that since the IIIC and later IIIE which best performances were obtained at 50.000ft.
    http://i146.photobucket.com/albums/r279/sampaix/IIIE-Optimised-Mach-Altitude.jpg
    Here to SHUT you off, a composite image which doesn’t need commenting…

    This nice document also show that the IIIE MAXIMUM ceiling with pressure suite was 75.000ft.

    http://i146.photobucket.com/albums/r279/sampaix/super530d8em1.jpg
    HERE: Typical Mirage 2000C (D/A) Intercept scenario with weapon release at 16.000m (Matra Super 530F), they would have to be able to see for (and TRAIN FOR) a SECOND wave, eventualy using Magics IR AAMs in a frontal attack, and THIS from, sea-level up to 55.000ft without pressure suite.

    Your accusations against me for bluring the difference between upper operational ceiling limit and normal operational ceiling can just be given back.

    You clearly didn’t study ANY serious documents on the French AdA nor on its role, doctrines and equipment, more to it, there isn’t any sign of the slightest level of comprehension from your side of the words OPTIMISATION and REQUIEREMENTS.

    These childish trick of yours deserve the Airfix award for Mickey-taking

    Se below:

    Scorpion82 =Can the aircraft operate there? Yes it can! Does it operate there on a regulare base? No! And why doesn’t it operate there? Because the performance at such altitude would be insufficient!

    Did YOU or disn’t YOU write the above nonsense?

    For someone who has a flying license and who is consistently playing the smart guy you know surprisingly few about operational realities.

    Who is making FALSE allegation and INVENTING himself standards here?

    Plafond opérationnel : 18 000 m
    http://www.defense.gouv.fr/air/au_coeur_de_la_defense/aeronefs/chasse_bombardement_reconnaissance/mirage_2000_5f

    HERE the Official Defense Minister “Newbies” link for you, what does it say???

    Mr Scorpion I as opposed to YOU do not NEED to DENY on INVENT Operational realities and take on people personaly while trying to pass myself for a poor victim of agression.

    I KNOW my ABC including military since i was precisely equiping the IIIEs with their Matras and AIM9s, which is clearly NOT your case and i am also not exacly a grounded keyboard warrior who pretend to know that a Mirage 2000 best performances are obtained at the upper-limit of its Operational altitude supposed to be <> 55.000ft when the IIIE was capable of 75.000 Maxi.

    This Operational altitude is fixed for a set of very good REASON and YOU keep ignoring them and trying to imply they are inexistant standards, infortunately for you these FACTS are well documented and some of us KNOWS about them if you DON’T…

    These aircrafts have been designed around a set of requierement including HIGH-ALTITUDE/HIGH-SPEED interception and their performances at these Operational altitudes reflect just that.

    As opposed to what you try to imply, these are NOT the “Operational upper limits” but the BEST altitude for performances (that given by the 1/ 2 is the most accurate), they actualy can fly easly higher than that but this would requier them to use a pressure suite for safety reason.

    Higher than that in case of decompression your blood would start to boil (I beggin to suspect this happened to you in your craddle time).

    As Dassault puts it with AdA/MN standard “Operatiopnal” ceilings imposed by the services once the aircraft performances have been validated Operationaly and for safety reasons. = BOTH 55.000ft (artificialy limited).

    As the 1/2 indicates the aircraft ( 2000-5F) REAL Operational ceiling is slightly higher than that.

    You of course wouldn’t know since you keep inventing all you didn’t learn and i’m sorry to say it turns out to be a lot.

    At 3.2808ft per meter this gives YOU 59.054ft Operational ceilling for the Mirage 2000-5F. Cheers.

    sferrin;1346883]Do you have any evidence to support that in this case that’s the issue? You’d have to have some truly incompentent management to pull that off.

    YES is DO.

    Just try your luck with Flight-International archives on the subject of F-35 because the aircraft is so well documented I wonder how you guys managed to miss that; i’ll be looking at my files but i got so many of them it’s a headache to manage… 7.2 (compressed) GB, 73,273 files, 3.114 folders for the subject of military and some civilian stuff, 80% of which is aviation and not included the CDs i burnt to save storage space…😮

    Now I could see the time between the programs having made it so a lot of the old hands with huge amounts of experience retiring but I’d have hoped the noobs would have got up to speed.

    Perhaps not all of them but certainly a good proportion might have done just that, After all ATF definition studies started in 1983, not exactly recently, more to it, the average junior team members looks like they were teenagers at the time.

    That’s the one thing I see as being a BIG problem. You get competent by working lots of programs, seeing lots of things done both the right and wrong way, and then incorporating that into your tool box of what to do and not to do. Some of the older guys worked literally dozens of aircraft types.

    Yes it IS an issue, there is an interesting article in F-I on the subject and one of the admited goal of the F-35 programme was to preserve design skills.

    .Opinion › News Article A dying design art? Unless industry can find some way to sustain its design skills, the JSF may yet prove to be the…industry has developed the capability to design and produce extremely complex and capable…
    http://www.flightglobal.com/articles/2003/11/04/173264/a-dying-design-art.html

    Who does that today when there have only been two fighter types ordered in the last 20 years?

    SAAB, Dassault, first their teams are small which makes it much easier to train new comers, second the apply the same technologies to their civil sector, plus it is also an admited goal of the nEURON programme with an operational follow-up already launched at perelimiray study level by DGA and very much the SAME for the Mirage 2000/Tornado replacement.

    Countries (the US in this case) would be doing themselves a favor to allow some of these prototype/experimental programs to go forward even if they are risky if only to improve the quality of the design teams.

    You’re right there expecialy because they have larger teams and perhaps less design work for them, but they don’t do themself a favour when the result is a HUGE cost over-run and totaly missed time schedule…

    The Gascogne EC-2/7 rafale squadron is being reactivated (former mirage IV P nuclear deterence squadron which was closed in 2005).

    The first rafales with the “colors” of this squadron can be seen in St dizier AFB.

    It will be fully operational in 2010 with the ASMP-A nuclear missile.

    source : air&cosmos from the 9th january.

    Good info thanks!

    Si i’ll take it they will be equiped with ASMP-As and endorse their traditional Nuclear role?

    How much does it have to cost to be a waste of money? The problem is that nobody knows what it will cost.

    http://www.theherald.co.uk/news/news/display.var.2479977.0.Spiralling_costs_threaten_British_Armys_US_fighter_jet_order.php

    Extract from above:

    I know thast that with much other programmes they have been pushing the technology envelop, but quiet frannckly, with the amount of redesign they ahd to go through i wonder how qualified the design team was in the first place.

    Missing their weight target by 33% in the first place was a clear indication that something went fundamentaly wrong (management or else) from day one…

    THEN i was AMAZED when some guy posted a picture of a water-tunnel testing of the LAST design with comments such as; “Something is pulling these wortexes inward”…

    The two last configuration side by side with the latest on the right.

    Quiet OBVIOUS what:

    They deleted the LEX which could have dynamicaly supported the expension of the vortexes outward as they use to do with the previous configuration.

    This phenomenon is known as EXPENSION and expension Wave at supersonic regime.

    Vortexes are sensitive to overal local pressure and from the inlet LEX they vaccate toward the nearest region of low pressure which is situated behind the canopy and along the dorsal spine…

    So as a result; they had to redesign the FINS forward beam and change its material, adding weight and loosing EM stealth in the process, because the now displaced vortexes were threatning to cause structural damages by aerodynamic strain.

    A problem already encountered with the F-18 AND F-22.

    Go figure how they can missmanage a design that much with the most advanced design tool in the world…

    http://i146.photobucket.com/albums/r279/sampaix/yourfile-2.gif
    I use CATIA myself in preparation for a simulation and i know what the package is capable of, entering material density datas you got little chances to miss your weight targets in the first place because as your design part evolves the package is going to tell you exactly what its weight will be and how resistand in ALL-AXIS it will be…

    My opinion is that the team which is in charge of F-35 is lacking the skills acquiered by the one which put F-22 together previously, and THIS is no free assumtion, it is actualy a known problem with US and other LARGE design houses due to the swap of skills from aerodynamicist and mechanic technicians and engineers to CG technician with much less experience…

    pfcem The comments made BY THE TEST PILOTS WHO FLEW THE FLIGHTS!!!

    Appart for the FACT that it did not at any time go supoersonic nor above 8 Gs of so this is PURE speculation.

    SPECIFIED MINIMUM ACCEPTABLE PERFORMANCE REQUIREMENTS!

    FALSE: Requierements weren’t giving ANY Mach (Supersonic DASH) but what DOES is the DESIGNED Mach LIMIT.

    You COMPLETELY missed it AGAIN!!! To LM, the US DOD & the USAF when talking about 5th generation aircraft (i.e. F-22 & F-35) the supercruise threshold is Mach 1.5. 🙂

    FALSE: Supercruise definition EVEN for L-M have little to do with a Mach value but CRUISE as defined by the USAF standards; the FACT that you don’t know them is YOUR problem, not mine.

    NO, NO LESS THAN Mach 1.6. It is a KPP THRERSHHOLD.

    FALSE: DESIGNED MACH LIMIT. Hard for you to comprehend what it means?

    YES IT IS! It is part of the requirements.

    NO it AIN’T, requierements are SPECIFICATIONS, NOT which aircraft it will replace (AGAIN).

    You’re simply atempting to rewrite history and the ol’ book here.

    NO, they have PURPOSELY NOT GIVEN ACTUAL PERFORMANCE VALUES & have instead just regurgitated KPP THRESHOLDS since they are already public & the aircraft EXCEEDS them.

    FALSE: They designed the aircraft with features which DEFINES its performances, another aspect of the industry you keep ignoring as well as the word LIMIT.

    NO, NO LESS THAN Mach 1.6. It is a KPP THRERSHHOLD.

    http://i146.photobucket.com/albums/r279/sampaix/2006familyws5.jpg
    FALSE: It is the airframe DESIGNED Mach LIMIT, meaning it is NOT designed for reaching higher speeds BTW it is quiet OBVIOUS looking at its design features only.

    Since you’re not aware just YET:

    The ability to supercruise will be mostly defined by the design CRITICAL Mach which depends on wing sweep angle.

    Considering F-16 with a higher level of optimisation for Operational ceilling and Max Mach can only reach 1.1 M with 40* swept leading edge and a laminary wing profile designed for supersonic speed, you GENIUS are going to tell us how you are planning to get F-35 supercruising AT ALL with a supercritical profile draging MORE in supersonic, a 33* swept wing and a similar TWR.

    So we established FACTS from L-M documentation no??

    No supercruise, structural G limitations from 7.0 to 9.0 G and M LIMIT of 1.6.

    Scorpion82 =Can the aircraft operate there? Yes it can! Does it operate there on a regulare base? No! And why doesn’t it operate there? Because the performance at such altitude would be insufficient!

    http://i146.photobucket.com/albums/r279/sampaix/2000-5F-1-7.jpg
    Please go and tell the 1/7 pilots their knowledge is insufficient, their webmaster incompetent, their aircraft not performant enough at Operational altitude…

    I SERVED at the SAME A-B it is the SOLE Air Defense A-B of the AdA, so i think these people from the simple PETAF to Pilots knows damned WELL what Operational altitude means…

    At 3.2808ft per meter this gives YOU 59.054ft Operational ceilling for the Mirage 2000-5F. Cheers.

    haavarla, you know sometimes people have documentation which is hardly available in the internet.

    Personaly i use a huge amount of it, and as i work with webmasters often enough i know for a fact that the net, as large a source of information as it is, represents only abot 0.5% of the declassiofied informations one can find…

    Best example are Jane’s datas, you can find article for free in their site but a year book would cost you near £500 and if you want the info in the CG format it will be much the same…

    Super Nimrod;1346704]It is one thing to demonstrate that it can integrate weapons and quite another to demonstrate that it can use them in anger. There is quite a lot about it on the UK Parliament website and it does suggest that some sort of integration will take place although no specific weapons are mentioned.

    Only in the furure and not wit this vehicle… This one is only meant to demonstrate technologies it is an UAV.

    It has to demonstrate some sort of capability in this area to justify its expense as like nEUROn

    Several Millions on the weapon bay and integrated systems only, the difference is visible with only a look at the budget.

    So it must be able to offer more than just a bit more autonomy to justify its existence, particularly when the UK is already flying a platform that already is attacking targets in Afghanistan.

    It’s technology demonstrator also meant to acquier the necessary slills to be able to design an UCAV in the future, IF the budget allows for it, forthe time being they still have issues to overcome to achieve full IR stealth and in this respect nEUROn will be the FIIST European Vehicle (UAVs or UCAVs) to be fully L.O…
