    My god the ignorance and arrogance in this thread is immense!! it has already been established that the UK Wont build it’s own national aircraft for bean counting reasons not that it can’t, Quite the opposite considering BAe’s fingers are in alot of aviation pies combined with vast experience of it’s predessesors and RR being argueably the most successful engine mfgr in Europe.

    the systematic destruction of British aviation industry both civil and military in the 60’s by both foreign entities and the labour party definitely damaged British capabilities to make matters worse the truly brilliant british designs at the time didn’t acheive the export success they deserved(i could make a list but everyone knows what they are), Harrier and Hawk only mustered a slight reprise but the capabilities to create a go it alone project are still there

    PS: anything i say on this subject is not to be taken seriously as i am a British Aerospace engineer, thus my bias is far greater than anyone else’s.

    I do agree, however the post-war financial situation in Britain precluded lots of high cost projects even if they were good. We just didn’t have the money to back them up.

    So, where’s the River RB-211 then ??? :diablo:

    Sorry – I’ll get my coat……

    Ken

    Yeah, I’m still looking for the river EJ200.

    The same again……………

    We just hope it doesn’t become a surface to air car then?

    The EJ200 should give them plenty of power over the afterburnng Spey engines that were fitted to Thrust SSC.

    EJ200 approx 20,000lb static full reheat
    RB168 (Spey 202) Approx 20,500Lb static full reheat
    Thrust SSC had two Spey’s the Bulldog 1 EJ200 (plus a rocket of course).
    I think the aerodynamics are going to be the most important aspect.
    The engine intake will also play a role, those on Thrust SSC were quite restrictive.

    Have you ever sat in the cockpit of a Lightning?

    The Blue Danube was more like the mk1 ‘bomb’. It was the first British atom bomb in service, or as they prefer to call such things ‘bomb, special’.

    just from (old:D) memory,wasn’t one of the victor losses caused by pitot/static problems ??

    cheers baz

    I must admit my (equally old) doesn’t always get it right.

    Ah the joys of the Victor and the Vulcan. Far preferred the latter as most of the bits acually fitted. Did a Victor taiplane change at Saints during a major- we had to try three different t/p’s before we found one that would fit and as for panels- forget it. All replacement panels needed cutting and drilling to fit unlike most of the Vulcan ones which just needed a bit of a trim. As for the small amount of Victors 2’s built it would appears that the CAS of the time was more enamoured with the Vulcan as there were questions concerning the structural strength of the Victors back end.

    Both the mk1 and mk2 prototypes were lost due to tailplane failure. The first was attributed to weak design. This was rectified on subsequent a/c. I heard from the older BAe workers that the second one failed because the pilot pushed it a little too far.

    [QUOTE=alertken;1314096]RH: CB is addressing “repeatability”. Boeing worked “to” drawings; UK parent-production teams worked “around” [QUOTE]

    There was an element of that in the Victor, I’ve often said of the mk2 that there were 33 built, 33 different ways.
    Engine doors, tank manholes even the spectacles (fairings around the jet-pipes) were very much original fit.
    Flaps, RATs including scoops, fuel tanks, airbrakes etc could be interchanged with varying degrees of success.
    There were some items that really took the biscuit. A couple of airframes had differently routed fuel-lines at the wing break (rib 330 joint) for which there were no spares provided (at the time). There was even one airframe that had eccentric bushings for the main u/c legs, again with no spares. Most notable about these sort of problems was the responses we’d get from Woodford. It always started with “oh yeah, we know about that”.

    Rob,

    Didn’t you once tell me that the parts of the Victor weren’t interchangable between different airframes?

    Cheers

    Cees

    About the only thing I found that was interchangable was a drain line from the HDU to the scoop. 😉
    But seriously, most systems were completely different.
    There was a stub-wing added (18in) at the root as part of the wing span increase.
    The inner mainplane to rib 212 was different.
    Different engines
    CSDU’s with a/c generaters
    The fuel connections were different.
    RAT’s.
    The mk2 had no 2 or 9 tanks.
    The shock-bodies on the wings (Whitcomb pods or window boxes)
    An air cooling intake at the fin root.
    Longer wing tips.
    Alot less batteries.
    Just off the top of my head.

    Mind you, it still had a morse key at the AEO’s station.

    How about a full stick of 31 bombs?………

    Wouldn’t want to get in the way of that lot!!!!!.

    John.

    If you look carefully you’ll see that it was five sticks of seven bombs, a full complement.
    Btw the Victor actually had enough room for 48 bombs but they were never loaded operationally.

    There were Vulcan tankers as well – XH558 was a tanker for a while. Vulcans needed an external gondola to perform that function though.

    That wasn’t a gondola that was a skip 😀

    The Victor could acually carry more bombs than a Vulcan (35 as opposed to 21), it’s maximum speed was about the same as the Vulcan but couldn’t quite fly so high. There were also less Victors produced than Vulcans.
    I think the biggest inherent flaw for the Victor was the mainspar in the Valiant. When the Valiants were grounded, there was an urgent need for tankers, and the Victor got picked.

    you mean this one?

    One that does NOT limit its speed to Mach 1.6.

    The KPP THRESHOLD (aka minimum accepatble) top speed is Mach 1.6.

    WHAT type EXACTLY is that? Pitot? Shock? VG? I’m interested.

    Really, what I am trying to say is Top Speed is not everything! The F-15 can do Mach 2.5 and the F-22 ~ Mach 2. Does that mean the F-15 is Superior hardly. The advantage of the latter is it can fly around @ Mach 1.5 – 1.8 Mach for extended periods. So, top speed is a relative term in fighters…….

    A high top speed coupled with high acceleration means you can break-off or re-enter a combat when it suits you. All other things being equal of course.
    However, it has been known for more than 30 years that most air combat takes place at high subsonic speeds.
