    And every one of these points will be the subject of haggling with howls of protest, hair being pulled out, screams of “UNFAIR!!!” and all the rest.

    LOL… The howls, hair pulling and screams of unfair are listed below:-

    We should be absolutely clear about what our bottom line is on this matter … we will not be able to purchase the aircraft.”

    “it is understood that the government is considering alternatives…” which “include prolonging the life of RAF Harriers or buying French Rafale aircraft.”

    “We are approaching important decisions that will impact on both UK and US military capability for a generation.” He said that the US needed to understand that a mutual commitment to the JSF was dependant on Britain having “the operational sovereignty that we require”.

    “Without the technology transfer to give us the confidence to deliver an aircraft fit to fight on our terms, we will not be able to buy these aircraft … I am spelling this out because it is so important to make our intentions clear. I know the British can be accused of understatement.”

    Now your description of howls, hair etc doesn’t seem to fit in with whats being said in a perfectly reasonable manner, (british understatement).

    The US expects countries to sign up to buy the JSF
    (see http://www.smh.com.au/news/national/sign-up-for-fighter-or-pay-more-later-says-us-company/2006/03/16/1142098602856.html)
    and are now putting pressure on the ‘partners’ to sign up quick to avoid being penalised!!, using your style of writing this seem to be pitiful whining from a seller who wants the mug to sign upto a very one sided dodgy deal!!!.

    The latest from the GAO is stating the JSF project be slowed to avoid the pifalls the F-22 has so often fallen into and I quote:-

    The US Congress’s Government Accountability Office said there had been inadequate testing on the fighter for it to be considered a mature design and that production should be slowed.

    “Significant development risk remains, and it is likely that current cost and schedule goals will not be met,” it said in a report.

    “To improve the chances for a successful outcome, we are recommending the JSF program delay production and investments in production capability.”

    According to DOD and the program office, through its cooperative agreements, the JSF program contributes to armaments cooperation policy in four areas
    1• political/military—expanded foreign relations;
    2• economic—decreased JSF program costs from partner contributions;
    3• technical—increased access to the best technologies of foreign partners; and
    4• operational—improved mission capabilities through interoperability with allied systems.

    It seems 1 and 3 are not being given the the weight of 2 and 4;-), in fact 1 is damaging foreign relations, and the opposite is true for the 3…;-) Ah they mean the access is one way -> to the US!!!, I see now….

    So to sum up we have the opportunity to sign up to a plane that is not been tested (only 1% flight testing complete), will not have a flying production representative airframe flying before production starts in 2007!!!, has doubled in cost so far and to top it all we are not be able to maintain or modify without the US’s approval and manufacture. Hmmm BARGAIN!!!, Oh and we have to give the US increased access to our technologies!!!.

    Did i miss something?

    Cheers

    The problem gentlemen is this, the US has a waiver scheme in place at the moment which is allowing tech transfer to proceed, BUT!.
    The waivers cannot contain the following:

    1. Engineering analysis -analytical methods and tools used to design or evaluate performance.

    This means you cannot be given the tools to measure things like its stealth signature, you sort of have to take the US word it meets the criteria;-), so after every sorte you have to return the craft back to the manufacturer to have the coating measured and touched up see No 2

    2. Design methology – which is the underlying design philosophy and engineering used in construction.

    This means you cannot easily develop improved coatings as they should work in harmony with the airframe, which is just as well as you are not allowed to measure them anyway see No 1

    3. manufacturing details – any processes and techniques required to manufacture items.

    This means you can’t build spares for your aircraft, you have to buy them from the US, you can’t make coatings that match the original see No 1 and 2.

    So you see the issue isn’t about posturing or negotiation, as the negotiation has been done it is in effect the following:-
    Either give the buyer access to maintain and modify the product or the buyer will be forced to look elsewhere, now thats not negotiation its an ultimatum!!!.

    I can’t see the president of the US travelling in the EH101 (US101 for the benifit of the USA) with a black box in it with european software running the flight controls or ECM that they have no idea whats in it!!!, imagine if there was something malicious in it… as you would expect the software and access to it will be handed over, or should the president trust the europeans?. (BTW for those in the US the French are European);-),

    Next thing you’ll be telling me is the statue of Liberty was made in France!!!;-)

    Hmmm friends of Dr Kopp perhaps!!! 😉

    Perhaps it would be easier to ‘Typhoonise” the Rafale than Navalise the Typhoon.

    The Rafale is structurally suited to carrier ops, I wonder how easy EJ200 would fit inside a Rafale? and how they would perform?, with the UK Typhoon fit Of avionics to keep it a common as possible with the Typhoon (Of course keeping the cheaper to maintain and technically better suited bits from the Rafale.

    If you were creating a hybrid for carriers which bits would you choose from which aircraft?

    The cost of any TVC must take into account the cost of the software changes to the FCS, this is the expensive part, the actual hardware is quite cheap, I suggest emailing ITP and asking them for a ballpark figure.

    They look like dummy’s, IIRC they are live if they have yellow bands and inert/training if they have blue bands…

    Are there any other colours?

    “But the double flame-out (which cause was actually never explained, only the reason why the engine couldn’t be relit was) that caused the Spanish dual seater to crash still makes me wonder…”

    The reason given for the double flame out was because the software was an upgraded version that was incompatable with the older series of engine.

    The engines flamed out, they tried to relight them, couldn’t and they stepped outside 😉

    Now where the software failed is a good question, was it in the thrust commands which caused the flameout? or was it in the windmill/relight procedure??.

    I’d like to know which, either way that mark of engine has now been superceeded by a few others heres the list.

    EJ200-DVE in 1988 (test-bed only – various changes throughout life to support development of flight engines)

    EJ200-01A in 1995 (first flight standard with C1 DECU)

    EJ200-01C in 1997 (modified HP compressor and reduced smoke combustor)

    EJ200-03A in 1998 (New all-blisk fan, new digital control C2 DECU and Lean-burn combustor with vaporisers replaced by atomisers),(these were the engines on the Typhoon DA6 aircraft that crashed due to software/engine problems).

    EJ200-03B in 1999 (modified LP and HP compressors, and rich-burn combustor with atomisers)

    EJ200-03Z in 1999 (“productionised version” – modified HPC and HPT, new OGV and LPT)

    EJ200-101 in 2002 EIS Production engine (new LPT)

    EJ200-101 in 2004 FOC Production engine (modified HPC and LPT)

    Now if anyone has more to add I’d be interested

    Hhehemmmmmm…

    Scorpion and Jwcook ares from a typhee extremly chauvinistic fan club, they write on a biased eurofighter website full of falses and imaginatives datas from the magical book!

    I didn’t just pull figures out of the air and put them on the website, look atthe bottom of the pages and you will see the references used, you may try to argue that the refrences are not authorative, but they are the best available to the general public, and at least you can see where the information comes from, then its up to you to decide on its accuracy.

    Fonk did you take a look at the ALSR doco, see anything interesting at all!!! 🙂 it may help you correct your position in some of these…. errr umm ‘discussions’

    Typhoon ALSR details

    Some very interesting stuff, some of which I thought was restricted!!!.

    Can anyone provide such details for the Rafale?

    Re the Typhoon DVI specs, you might find these useful.

    http://www.smiths-aerospace.com/Documents/Products/Speech.pdf

    • High recognition performance >95% in flight
    • Fast Response time <200ms
    • DVI vocabulary of 200 words
    • Flight proven counter measures to overcome the Environmental factors of Noise, G loading and Stress
    • Speaker dependent , language independent with full multilingual capability

    and

    http://www.eurofighter.com/News/Documents/DVI_FS.pdf

    The Speech Recognition Module (SRM) is a speaker-dependent, connected word, voice recognition system with a maximum vocabulary of 200 words, of which 107 are implemented in the operational unit. Memory growth to 400 words is now available. However recognition performance is the priority, required to be in excess of 95% in the cockpit environment with development promising stress tolerant algorithms to 98%. The module accepts
    continuous natural speech at 100-140 words/min with an average 120ms response time. The voice generation provides high quality digitised speech encoding at the rate of 120-160 words/min utilising a 200 word vocabulary.

    So the proof is there,
    Vocab = upto 400
    Av response= 120ms
    Recog= >95% increasing to 98%

    That said, they do seem rather similar.

    Enjoy

    I just looked it up, is the number of Raptors not included in upgrades 59!!, at least thats what I’m gathering from comments like

    “Pilot production for the F/A-22 is proceeding apace. Eventually, Tyndall is expected to have a fleet of 59 Raptors for pilot training. They will have full air-to air capability but will lack some of the ground-attack gear slated for later models.”

    http://www.afa.org/magazine/feb2005/0205raptor.pdf

    I have a couple of questions, how many will not be ‘improved’, and why???.

    in reply to: 50th production Eurofighter delivered #2622539

    And of course all Eurofighters will be upgraded to Tranche 3?

    AFAIK that depends on the airforces concerned!, the tranche 2 mods should be fleet wide, there is not reason why they can’t be upgraded to tranche 2, tranche 3 may include more radical changes (if they go ahead with tranche 3 that is).

    Each national airforce may not wish to fully upgrade their aircraft, or indeed be able to afford it at that time, so there is bound to be some differences as there are now (LWR not on German Aircraft).

    So the answer is they will try to keep a common standard as much as possible subject to national requirements, there are no technical reasons why its can’t be fleet wide (the first couple of T1a’s may be excepted unless they change the fuel system in the wings)

    The difference with the Raptors is they have stated the first 49 will not be upgraded, Hmmm is that due to differing production standards I wonder!!!!, 49 is not an insignificent number for the estimated buy, in fact 49 training aircraft is a bloody large number, any reason why?.

    cheers

    However re the F-22’s IIRC 49 of those are not to be included in the spiral upgrades and will remain ‘training’ aircraft, so the production numbers may not tell the whole story.. 😉

    Those laser detectors, two forward of the canards and two at the wing roots (towards the top rear) where are the others?.

    somewhere below??
