    “i have not seen any reports that stated that the RSAF preferred the Typhoon.”

    I have, both open source (see AFM) and closed.

    I’d would be very interested if you could flesh this out a bit, I had heard the Singaporeans were impressed, especially with the radar, flight dynamics and serviceability issues.

    The french are pushing the Rafale Very very hard, and they may drop the price by an extreme amount to get this order.

    As EADS/BAE can offer access to several areas of Tech transfer, France will certainly have to pull out all the stops to get the ‘orphan’ adopted ;-).

    The F-15 will have the advantage of political clout, but Singaporeans are quite well respected for clever buyers, so this competition is very interesting to observers!!, and is still wide open, Hmmm – what are the bookmakers saying???

    So please Jackonicko give us some hints on the RSAF’s thinking ….

    Cheers

    However they did not fly a test aircraft, but a Tranche 1 series production aircraft, with little test instrumentation. And it was a double seater.

    I know, the aircraft flown in singapore were production standard (IIRC Tranche 1 batch 2) you asked what the differences were between a test aircraft and production aircraft, I tried to give an overview!!, and didn’t do it very well it seems…;-)

    The weight difference between a Double seaters and Single seaters is around 150kg or so.

    Seahawk wrote:- Like What?

    Like the Radar, Pirate, Dass, each test aircraft only had subsets of the final configuration, the rest of the bays had test equipment crammed in, data recorders, sensors, comms, the test equipment weighed considerable more, than production equipment, remember the bays are only half full on a production machine to fulfil its contracted upgrade potential.

    If you mean software then the latest addition is ALSR – Automatic low speed recovery, in the Flight control software,This was one of the problems that qinetiq highlighted in its infamous ‘don’t release to service’ report

    One of the key features of the Eurofighter aircraft is the quadruplex fly-by-wire Flight Control System (FCS), which provides the aircraft its outstanding manoeuverability. FCS is also an important prerequisite for the Eurofighter’s unique carefreehandling qualities, enabling the pilot to concentrate on his mission rather than on basic airwork. With the first flights of GS002, the first flown production single-seater for the German Air
    Force, a new and important feature of the overall carefree handling functionalities was flight-tested at the EADS Military Aircraft Flight Test Center at Manching in late October 2004: the Automatic Low-Speed Recovery
    system (ALSR).
    ALSR prevents the Eurofighter aircraft from departing from controlled flight at very low speeds and high angles of attack. To achieve this, the ALSR, being an element of the overall FCS system, is able to detect a developing
    low-speed situation and to raise an audible and visual low-speed warning. Thus, the pilot will have sufficient time to react and to recover the aircraft manually. If the pilot doesn’t react or ignores the warning, the ALSR will actively take control of the aircraft, select maximum dry power for the engines and return the aircraft to a safe flight condition depending on the attitude by either using an ALSR “push”, “pull” or a “knife-over” manoeuvre.
    The first pilot ever who fully exploited the ALSR capabilities in flight, doing this on Eurofighter production aircraft GS002, was EADS test pilot Karl-Heinz Mai, who described his experience with the new system: “It worked tremendously well – ALSR is a real confidencemaker in the low-speed area of the carefree handling envelope. I’m convinced this is one of the most impressive features of this aircraft!” “After making a cautious approach to a few low-speed recovery corner points, I’ve gained confidence in the system so rapidly that I was able to enter the extreme low-speed recovery set-up with 70 degrees nose-up attitude and power idle without any hesitation”, said Mai.
    “The system then worked as described –without any pilot action. Impressive!” Mai congratulated in particular the FCS engineers, who work in an area where EADS has overall design responsibility. He also praised both the ground- and flight test teams as well as the qualification and certification staff, who had
    made the ALSR and its proof of functionality for the production flight cceptance test of the single-seater aircraft such a success.

    No mention of tradeoffs in there!!!, but the tradeoffs cross over at an optimum point, if you fly at other tempretures/altitudes/air densitys, then your speed suffers accordingly from thrust issues.

    M1.21 isn’t too shabby at all!!!!!, has any other contender mentioned cruise speeds in military power?

    That ‘bit more than mach 1’ was actually M1.21.

    Source AFM:-
    And its reported that one Rafale programme insider grudging said about the supercruise “they didn’t wait for a cool of the evening, they didn’t wait for a cooler day, – they just went out and did it in a hot daytime tropical environment” .

    The Typhoons apparently flew 28 missions totalling 35 hours,

    reported quotes :-
    “The Singaporeans are over the moon”
    “Typhoon exceeded all expectations and blew their f-16’s out of the sky”

    So it looks like the Typhoon is in with a chance.

    it’s RBE-2 and I wonder how you can tell that :rolleyes:

    if by “mediocre” you mean it has a shorter range than the captor, than yes, you’re right…

    But you may learn that range is not necessarely what make a radar better …

    BTW, tell me what advadage this better range gives to the EF ?
    Can it shoot before the rafale ? no…the amraam still has the same range.
    Can it detect a rafale first ? no… the captor’s microwaves will be detected by the rafale RWR first.
    Can it lock the rafale first ? well probably…it’s the only advantage.

    No one can give you any real answers, its all pure conjecture, both aircraft are going to AMSAR, so both systems must have shortfalls somewhere!.

    As for an easier upgrade path, well it may be easier technically to upgrade the RBE-2 than upgrade the Captor, but will the finished product be better, If what your saying has any merit is an ‘easier to upgrade’ RBE-2, or a ‘virtually all new’ Typhoon AMSAR system the better system..

    BTW from what I’ve heard the Captor is getting new software/hardware that will ease the upgrade path, I have not got a clue how much it will ease it though….

    In the RAF they are called Eurofighter ‘Typhoon’s’

    The company Eurofighter GmbH make the Typhoon and they are furthur identified by numbers:-

    There are twin seat Typhoon T.1’s (12 x batch 1 trainers) or twin seat Typhoon T.1A’s(batch 2 Trainers), it really depends on the fuel guage thingies in the wings!!!. the batch 1 trainers didn’t have the fuel guage modification that the batch 2 have, AFAIK they will stay as T.1’s and will not be upgraded to batch 2 T.1A status.

    The single seaters will be Typhoon F.2’s.

    I would imagine these designations should hold together as tranche 2 come along, because as tranche 1 aircraft are upgraded to the next tranche level, all aircraft should be at the same level.

    BTW it looks like the Typhoon can supercruise at 36k at M1.2 with full AAM load and fuel tanks… thats about what I thought it could do clean, but someone said they got an answer from Eurofighter saying it could do it in this config, exceptional eh…

    It seems an simple equation doesn’t it.

    but the rafale is supposed to have active cancellation of radar returns, so maybe its actually more stealthy than the JSF, depends on what the real specification are.

    Adrian_44 Just out of interest, where did _you_ look to get those RCS figures, where there any conditions put on those figures, such as freq, aspect etc?.

    or are we talking about some the (hmmm… whats a polite way of saying this) ‘less credable’ resources on the web!.

    Hyperwarp IMHO it looks quite a bit like like AMSAR!, and looks like around 1000 mmics (IIRC there are two MMIC per card).

    Yet another optomistic news snippet:-

    Finmeccanica: ‘optimistic’ on II tranche orders for Eurofighter, We are moderately optimistic that the thing can happen shortly ‘. Cosi ‘ the president and a.d. of Finmeccanica has said: ‘ We are to the final phase ‘ of negotiatation even if there still exists a small resistance in the English Government ‘.

    Its in Italian, so any better translation into English would be greatly appreciated.

    Could something be moving?.

    It can be fired from height and it dives down to cruise to the target.

    I’ve been a little pessimistic about the signing for a while, but recents snippets like this http://business.timesonline.co.uk/article/0,,8211-1294304,00.html
    seem to indicate that something is moving, there have been several little bits of news that may point to an imminent signature.
    I usually rely more on what the stockmarket is saying as they have money tied up in the Business and so have a vested interest.

    Lets wait and see if anything happens in the next two weeks……

    BTW Hoons off to India!!!, they could be an export possiblility! $$$.

    Not being party to the negotiations or having access to anyone that is, I would’nt begin to guess the stage negotiations are at.

    The program looks like having to renegotiate prices on parts a second time due to the UK’s delay in signing, some manufacturers are producing parts out of their own funds (while not having a contract). others are on go slow manufacturing or switching to other work in the meanwhile(layoffs have been mentioned)

    The UK is causing all sorts of problems with its ‘delay’, the Four partners have until now agreed to share the cost increases, this looks like an increasingly fragile arrangement with the germans in particular getting a bit upset(quite bloody rightly IMHO).

    Signature by the 15th?, I don’t know, its possible I assume, Bridging contract for long lead items may be an option!!.

    I don’t quite understand it, the UK MoD have said they are commited to the Jets, the long lead items are not going to change specification, Bridge the gap with long lead contracts!!, its not that hard to do (except they may have already done this, so it might be a bit hard:-)).

    Someone has to get a move on..

    Cheers
