    Spud, the downturn in economy had nothing to do with the 2004 redesign, and that was quite a big chunk of the lateness.

    Cheers

    Add the groundings due to technical issues. Would be interesting to see where a “lack of funding” alledgedly blocked the development of the programme!

    Technical issues aren’t unusual for technologically complex programs. The relative transparency the US pursues these days also adds to the sometimes ill perception of the program. Coupled with a deeper lack of understanding of the subject im general it translates into the mess we are witnessing here in these forum discussions.

    et, no, they both flew from Italy to Azores and from there they flew for the USA.

    it is a 4000+nm trip

    if you wanted to go from Italy to the USA, after 2445nm you’d just end somewhere in the middle of the Atlantic

    You are right the distance of 2442 nm applies to the route flown from Lajes to Patuxent River. Doesn’t change anything wrt the statement however.

    Some customers have chosen to add CFT provisions to their T3s. Either would add around 1500 l, i.e. 3000 l in total. Thus far, however, no one has contracted its full scale development. So no CFTs for the time being.

    Gentlemen perhaps you read what is written…

    During the 2,442 nautical mile flight to the US

    With flight coordination handled by NATO controllers in Ramstein, Germany, the F-35 and the Eurofighters refueled three times during the 2,105 nautical mile first leg flight to the Azores.

    and

    An hour before the F-35 was due to land at Patuxent River, the Eurofighter and one of the tankers headed to Pease Air National Guard Base in New Hampshire

    So the trip for the F-35 was 2442 nm, the Typhoon and a tanker diverted ~1 h prior the F-35 landed at Patuxent River, both flew the “first leg” for 2105 nm that leaves an additional 337 nm for the F-35 on the final leg which was probably the last time both aircraft refuelled jointly before splitting to head towards different destinations.

    That appart we are here talking about a clean F-35A with an internal fuel capacity of ~8.3t and a twinseat Typhoon, which even with 3 x 1000 l tanks, has a capacity of ~6.5t!

    One may add that the whole world isn’t employing LO designs of any magnitude any time soon. Many airforces still operate 2nd and 3rd generation types and 4th generation fighters still roll of the production lines as of today. The latter in particular won’t vanish anytime soon and as long as that’s the case 4th gen types remain operationally relevant. Some may argue that the threat posed by advanced IADS will severly limit the survivability no non LO designs, but even that is speculative given the constant race between CM and CCM.

    Leave Christ where he is, before Seahawk took that quote as signature, it was an interview of a german pilot published in a paper magazine (combat aircraft, or air forces monthly, as I said, can’t dig it right now). It was an interview after germans made their few months aur policing over baltic states, and, while the “under the snow picture of the Typhoon is nice, nothing tells you it can do it for long time and remain fully operational.

    In any case, we agree that it is very likely that Canada takes the Boeing offer regardless of qualities of other aircraft proposed

    Possibly sentiments towards the retirement of the F-4 back then. Typhoons are flying in winter as they do in summer.

    Well gents static figures are only a small part of the performance envelope of anything. Whether we are talking about engine thrust, radar range or missile range… If such figures are quoted without a context they are even more meaningless.

    Not sure I get you with the jamming, Rafale jams “much better”, The Typhoon has front and rear hemisphere jammer in one wing tip and a couple of TRD’s in the other tip, one thing I have not looked into is the Typhoons “last ditch maneuver”, I haven’t got a clue as to how effective it could be, it must be somewhat effective as its been provisioned, love to know if anyone knows any details.

    DASS provides three types of maneuvers. Support maneuver are designed to maximise the effectivness of the counter measures. Escape maneuvers are designed to deplete a threat missiles energy state to outrun them, if counter measures ressources are constraint to defeat the threat. Last ditch maneuvers are simply cues to a missile on finals.

    Should be yes.

    A bit later than indicated and not yet a contract, but it’s finally a first step in the right direction!

    Terrible video! Gave up watching it after 2 min of mostly empty skies, jittery etc.

    While not a customer funded program yet, UTAS has at least studied repackaging the RAPTOR sensors into a smaller pod that would fit Typhoon.

    Haarvarla,

    we are talking about two different issues here. Fuel and stores management are inflight tasks that the FCS has to cope with. Ofcourse there is s CG range that an aircraft can deal with, but beyond that the FCS itself is no solution even if it can deal with greater CG ranges! Why? Because it’s about mass distribution and the related inertia. If these change you are automatically loosing performance and have to deal with unnecessary trim drag penalties. That’s why it is important to carrfully observe the impact of anything that you add or remove from the aircraft. If not your FCS might cope with this, but and can only compensate by counter trimming the moments which means a lose of performance!

    Take a meter long stick and put weight on it on variable positions stretch your arm out with which you hold the stick and move it around. You’ll notice that it will be increasingly difficult the greater the weight at the end of the stick. Up to a certain point you can compensate, but only with sufficient force. Put the same weight closer to your hand and it will be much easier and even possible to deal with weights that you can’t handle if they are at the opposite end of the stick. It’s simple physics!

    Fighters’ designs account for a range of Cgs. I’m sure minor tweaks to ballast and FBW would suffice, as has been the case with all the prototypes to varying degrees since the first flight of T-50-1.

    You aren’t messing around with FCS all times the weight changes, hence ballast is the way to go in such cases, unless you have changes that in sum may suffice FCS amendment. And what we were talking about here were changes on the tail sting. I just don’t think they have removed KS-U to make room for a rearwards facing array. It’s nonetheless interesting to see how the OEIS arrangement has changed with virtually all prototypes thus far.

    It will be interesting to see how the final arrangement will look like.

    They will most likely not scrap them, but put them into storage.
