    And assuming the early jets are “mistake jets” is more nonsense.

    A vast majority of the early jets are training and evaluation jets. The partner nations are not scheduled to order their jets until the SECOND round of Block 3 jets.

    If we should remind you on the Raptors tail section heating issue, and fin buffeting… Those were problems discovered when quite some aircraft were already delivered and fixing those issues certainly costs more money. The F-35 has at best completed 3% of its intended flight tests and you pretend to know that there won’t be any additional problems, which could increase costs for the early jets due fixing issues which were discovered to late? Sorry but that is nonsense, ruling any everything which does not favour your beloved Lightning II. I should start to save your guys laughable naive comments and show them to you once things are real.

    It’s really not that hard to believe a Typhoon getting a radar lock on an F-22 during unofficial trials, considering that the F-22 flies with radar return enhancers when not in official testing or exercises. The whole thing about the F-22 pilots “crying off” is most likely sensationalist journalism.

    That’s the interesting part, in the first place they stated it never happened, later they stated the Raptors fly with RCS enhancers. Whatever that means. I have seen a good collection of sources about these supposed incident. I could repost it here, but I think it will just heat up old unwanted discussions…

    The reply to Scopion is as follows when asked wht he meant to write.

    Cheers
    (hope you don’t mind me replying to this Scorps.)

    Short answer is – MTOW = 24,500 kg.

    No problem Jwcook.

    Yes, but we know it’s wrong. What we’re trying to work out is what part is wrong. The author could have accidentally confused lbs & kg (probably a typo) when writing it, & an editor later added the conversions to kg. I know that doesn’t explain the 20000.

    The article was written by Jon Lake and I have already forwarded a request to clear up what he meant. I’m certain we’ll soon know what he intended to say. 😉

    There were similar graphics available for the F-22 showing that the last of the 750 would cost less then the F-15E. We know how it ended.

    History doesn’t mean anything to these guys, they swallow the crap spreaded out and won’t even waste a second about how things could go. 😉

    24500 kg would be a slight increase in the notional max T/O weight, to what it’s been reported it has actually been tested at.

    Yes but the article states lb not kg and we know that the MTOW for T1 isn’t 20t, but 23.5t with an overload possible.

    Well actualy my friend you should start to understand something yourself.

    If it is groundspeed you are refering to, he wouldn’t even bother transfering it into mp/h and stick to kt anyway, in the event that HE had to so some navigation involving computing groundspeed HE would have had to use the knot.

    Mph/ is for tourists; as a US (westerners graduated from Edward uses the same datas/procedures) test-pilot he would use standard and procedures according to his profession not that of truck drivers.

    These diverse speeds are expressed in kt, ft/s or m/s there is no point trying to imply that a test pilot will have the time to amuse himself with translating these into touristic measurements while in flight.

    I know these guys are brains but the less they use it the better job they can do of what they do and there is a lot to do during tests and while you’re at it try to find us any aerospacial company calibratring their equipement in mp/h.

    The Mp/h measures are given by PM who try to impress the public but does a pretty bad job of informing those of us who uses these standards for one reason or another.

    Reason for procedures and standard to exist.

    In the end he talked for public consume and the 1600 mph figure might well be suited to the usual citizen, who might not even be aware of knots.

    I’m aware of MBDA own statement and you should have to look at it too, please.

    As i was saying, not there YET and it is only 5 month ago.

    = The problem is that no one is anywhere near to demonstrate a viable solution for firing an AAM behind the shooter otherwise than with a link-16 which negates the idea of stalth and in LOAL mode (Naturaly).

    It was an in service firing at a chasing target. It hasn’t been stated in which way the missile was launched, but there are usually two ways to achieve this with offboard data or the HMS. Threat warning sensors might work as well in theory.

    Supposely Tranche 2 has increased MTOW compared with Tranche 1.

    November 2009 Air Forces Monthly (pg 63) mentions this, but completely stuffs up the weights:
    ‘…increased from 20,000 lbs to 24.500 lbs (9072 kg -11,113 kg)’.

    Anyone have the correct weights?

    That’s obviously nonsense. Empty weight is given with ~11000 kg since the late 90s and it’s for sure not the MTOW.

    F-22 outranges the F-35…

    Yes you read right the F-22 has a longer range than the F-35 with ~6.5 t more empty weight, 13t more thrust with two engines, but just 1t more internal fuel!

    Yes, the F-22 can fly higher and faster, and it has longer reach.

    It must be true, it was said by Mr. Beesley.

    I think these issues have been well documented by the press.

    The real bad news is that F-35 was supposed to be cheap and is comparatively way simpler as a design than F-22.

    Ending up with more design and technical problems than F-22 is no good sign at all.

    And that while the supporters claim that LM learned its lessons:diablo:
    To my understanding the JSF was originally supposed to be less complex than it is envisaged now, which might be part of the dilemma.

    Does this mean that F22A can now be sold to Japan?

    Not necessarily. If the export ban is lifted soon there might be a little chance, but given the fact that F-22’s production is meant to be finished by 2011 it is difficult. I can’t imagine that the US is willed to pay for keeping an unemployed production line open to wait for an uncertain order.

    They probabley talk about the X-31 a joint technology demonstration programme between Rockwell & DASA, with DARPA support and later USAF/USN support. The X-31 looked merely like a down scaled, single engined Eurofighter and featured 3-D TVC. TVC R & D was the main purpose of the programme, which saw 2 prototypes being built, one of them crashed. The other one was used for automated TVC landing trials after being refurbished around 2003 or so.

    I thought the general opinion was that TVC on the eurofighter would be a marginal investment, given it’s dominance other it’s competitors in manouverability already vs the weight penalty imposed by TVC?

    In the more recent past Eurojet mainly investigated in the issue cost and weight. If they can demonstrate that the TVN is reliable and light enough there may be some interest, but I wouldn’t bet on it at all.

    How do TVNs enable more thrust in supersonic cruise?

    The TVN of Eurojet is more a kind of “4-D” nozzle. It can’t only rotate, but also change the diameter not just in the convergent/divergent way. Watch the videos on the link and you’ll know what I mean.
