    Outsmarted me by designing a flying brick? Hardly..

    Well, they get paid for doing it. Do you?

    MSphere, why is one of the two of your images reversed?

    I wouldn’t know. I just fix them, not talk about them…..

    I am baffled by the lack of supercruise capability, though.. What exactly is responsible for that?

    High bypass ratio?

    Again, very nice photo’s. That was certainly a day to remember for you all. Well done!

    Nice photo’s, especially the drogue.
    This would have seen it a few times…

    The 24cm difference in intake dimension would indicate a greater mass airflow. Mass and velocity are the key figures to thrust calculation..

    It is engine related. They were used for undoing V-clamps. Very useful when doing an engine change, which was often!
    They came in 4 sizes. 2BA, 11/32″ a/f, 3/8″ a/f & 1/4″ BSF.
    They are actually Vulcan related, the section and ref numbers for them came from Olympus related tools.

    Btw, that last photo, the underside of the edge looks like it has been repaired. Is that so?

    The Tornados are loud. I remember a lot of civilians living close to the airfields getting grants for double glazing when the Tonkas were introduced (Honington, Marham etc).
    I know of one defensive tactic the aircrew used to have when they were WE177 capable, an eye-patch….

    The Foxhunter radar was designed to track 6 targets if I remember correctly, was that so Dazza?

    well it has been a while since I done all that stuff but I believe your question is not complete. I believe you need the two stagnation ratios and some other values to calculate that. I’m almost 99% sure of that, but I could be wrong. I am an old man.

    I’m not so young myself…
    Ok good point. Let’s make it simple and complete. Thrust = M x delta V. M= mass airflow. Delta V= velocity differential (airflow in/airflow out)
    Example jet engine. Variable reheat. SLS (sea level static).
    Ambient: 15 degrees Celcius
    PR (pressure ratio) 9:1
    Mass airflow 156 lb/s
    Rpm maximum 100%
    Jet pipe temp 1000 degrees Kelvin

    Reheat engaged to full
    Ambient: 15 degrees Celcius
    PR 9:1
    Mass airflow 156 lb/s
    Rpm maximum 100%
    Jet pipe temp 1690 degrees Kelvin
    Simple figures. Simple calculation, it’s a ratio. It is a percentage. It’s the simple answer as to how reheat works.
    pressure doesn’t rise when engaging reheat, it is modulated by turbine pressure.

    Of course when actually moving, due to the dynamics, values change. However, the ratios remain the same.
    As I said, it’s about understanding, not just looking it up on wiki or wherever. Andraxxus likes to bamboozle me and others with figures, I’m just asking for clarification…

    The thinking at the time was a longer CAP for bombers. Air combat with fighters was at the time very low priority, and proved to be less successful.
    The F14 and 15 a/c are far more agile. The Typhoon was developed to compensate for that.

    At the time we did point out to the aircrew that the Buccaneer was faster than the Tonka when carrying the same bomb-load (4x 1,000lb).
    I do believe they were looking into stretching the IDS to F2/3 dimensions plus a few extra’s for more capability and higher speed (there was talk of 1,000 mph at sea-level).
    I know the IDS had the intakes locked in the beginning, this also restricted it’s low-level speed.
