    Speculative? An iteration of the large twin engined Carver. This was the larger “Mirage 4000 type” perhaps?

    From the same source as above.

    I have no idea how accurate or innaccurate these drawings are, or whether they are purely speculative or draw on semi official info.

    The intakes look decently sized to me. And anyway, it is just a mockup and has no engines fitted.

    The last picture appears to have nose mounted canards.

    … and increased fuel consumtion for an overly powerful engine not really needed for the training role. If you limit or govern the thrust, you still have a heavier engine to lug around than is necessary.

    It would be nice for a limited run of LIFT/secondary strike’interceptor class thoough!!:cool:

    And while the UK contribution made Jag the pre-eminent low level aircraft that it is, the superb French undercarriage was the foundation of the type’s rugged deployability.

    While not as versatile as the F1, the Jaguar was (IMHO) streets ahead in terms of usefulness, and was far more deserving of development.

    I notice that the jaguar undercarriage superficially resembles the Mirage F1’s … is there a connection?

    I’m confused by your slightly contradictory last sentence?:confused:

    When MiG first talked about reconfigurable flight control systems on the MiG-AT I was blown away by the idea – the ability to tailor handling characteristics to ape or match those of a particular frontline type seemed to be a compelling advantage to me, as a lay person, and as a PPL with some FJ experience.

    But talking to flight training pros, it soon became clear that this was an impressive capability that was not actually needed, and that wouldn’t really be used. There would clearly be some impact in reducing conversion time to a frontline type, but the pure ‘type conversion’ element of most OCU courses is very brief anyway. A trainer that handles like a Hawk simply isn’t a problem.

    Good point. I suppose the manufacturers will often come up with a new feature to make their product ‘sell-able’, but whether it’s needed or not!

    I suppose there should be a finite increase in engine thrust relative to fuel consumtion if the vehicle is to be used only for training and not for secondary strike/interception duties.

    Points well made Jacko.

    I still think that the next few years will be important regarding additional sales of the Hawk as opposed to sales already in the bag but not yet delivered.

    The Hawk is an exceptionally capable trainer, but it comes with a very hefty price tag. Whilst it has been very effectively upgraded during it’s life, it’s design origin point was 40 years ago.

    Fly-by-wire (and Fly-by-light) in the future, as well as aerodynamic, structures, and fight control design has moved along quite a bit since then. I agree that the driving factor will be cost, but the Hawk is a pricey vehicle. The ability to configure the aerodynamic profile/envelope of the vehicle via software inputs to the flight control system, and not just cockpit/weapons management might also be an important factor.

    I like the Hawk. If I was to buy a trainer right now it would probably be my first choice. I wouldn’t say that with certainty in 3 to 5 years though…

    In its current production guise (LIFT/127/128/129 etc) Hawk is:

    Still the best advanced trainer out there, bar none.

    Still perfectly capable of providing the kind of cockpit environment that is representrative of current and future frontline platforms.

    Capable of downloading current OCU-type training to a cheaper to operate type.

    Supersonic capability is irrlevant for an advanced trainer, and the UAE’s decision, while surprising, is hardly Hawk’s death knell.

    Jacko, while the above points certainly were true for many years, I’m not sure how true the above arguments still are.

    There are now more recent products coming on line, such as the T-50, M-346 et al. Whilst the Hawk has been continueously upgraded and is one of the best advanced trainers still available, I feel this will change within the next 5 or so years. Knowing the length it takes to introduce new systems these days, I feel that the the late 60’s early 1970’s design origin of the Hawk will start this process of change, especially when the new generation trainers start coming on line in the next few years.

    With the emphasis on supercruise and retention of high speed energy in AirtoAir combat now gaining prevelance, perhaps the time for supersonic trainers is now?

    another shot to show that strange tail arrangement !

    And you can see the green twin seater in the backround. It has a low-slung wing.

    The only picture of the complete ac is this blurred picture … and YES – at least for my opinion – the intake looks different !

    Thanks Deino. The intake looks considerably bigger. Seeing as some of the airframes are actually quite recently built, this may mean that the H-6/Badger design will be in service longer than the B-52’s!!

    Analysis: China attains nuclear strategic strike capability
    HONG KONG, Sep. 7
    ANDREI CHANG

    Column: Military Might
    China has been upgrading its H-6 bombers and producing H-6K bombers in an effort to improve its aerial nuclear strategic deterrence. The subsonic speed of the H-6 and non-stealthy sorties prevented it from breaking through the air defense networks of Russia, the United States and Japan. Fitted with D-30-P2 engines of greater thrust power, the new H-6K has a greatly increased range and combat payload. The two engines, each with a thrust power of 12,000 kilograms, may enhance the H-6K’s ammunition capacity to around 12 tons, enabling it to carry large long-range cruise missiles.

    Does anyone have any pictures of the re-engined variant? I’m assuming that perhaps there will be a slight difference in intake/intake size due to the fact that the D-30 is a turbofan with probably a higher airflow requirement.

    Equally they tend to be deflected by things like twigs and branches or sheets of glass that will not deflect a standard 7.62mm ball round.
    In other words the heavier 7.62 x 39mm round is more likely to get to the target in brush and will penetrate a small tree and still have the capacity to kill. Most small calibre rounds will dump all their energy into a tree and do little to anything behind that tree.

    This is the precise reason why South Africa, after replacing their 7,62mmx51 FN’s with the 5,56mmx45 R4, still kept the FN LMG in 7,62mm NATO. The larger round was found to be more effective in the African bush than the 5,56mm, which was more easily deflected by heavy twigs or branches.

    The original AK-47 had a machined body and was heavier than the AKM with it’s ‘cheaper’ pressed lower receiver. the original was also heavier.

    Since the Mirage F-1, the Mirage family has always had a fixed probe (this includes the Rafale as well). My guess is that is just makes for a bit less maintenance (a retractable anything is always a bit more maintenance intensive than something that’s fixed).

    Of course, as noted on another thread, the South African Mirage F1AZ did have a retractable probe of the same type fitted to the Super Etendard. This was as a result of the replacement of the air-intercept Cyrano IV with a smaller AIDA ranging radar, thus freeing up space in the nose.

    I find the latest Russian retractable probes quite interesting in that with a small fuselage plug, a retractable probe can be installed. I think this is because the main body/piping of the probe appears to be set at a much steeper angle relative to the planes forward fuselage.

    Of course it is. A large radar that can look deep into Russian airspace… the americans have never had that before… they must be drooling. Hope it is worth the loss of the INF treaty and other treaties too more than likely.

    Hmmm… that is a good point.
