    Perhaps you’d better read the blurb more carefully. It does state the first Merlin powered Mustang flew from Hucknall

    Excellent, it’s really good to see under the skin of these beasts.
    I bet those inlet guide vanes have caused some language when caught against re-emerging legs and other soft dangly bits!

    They’re actually called vortex generaters. Ooh all those young lekkies sent to find new fuses for them:diablo:

    Re the “vortex generators”, were these not introduced as “flow straighteners” for the Avon302C engines, to allow the 102% rpm in the SaudiKuwait temperatures, rather than the 100% of the avon301 fitted to the F6??

    I may be getting on abit and I was rather young (17) when I worked on Lightnings but I do remember vortex generators in the intakes of 3’s and 6’s. I had to navigate them often enough. Thinking about their use I would imagine they were fitted to ensure enough flow separation to ensure number 2 engine wasn’t starved of air.
    Was the 301 limited to 100%. I know the 300 series engine was limited by the intake. When the zero stage was added it increased the airflow through the engine from 156lb/sec to about 171lb/sec. The intake couldn’t take the increased flow at speeds below 1.6Mn, so a T1 control was fitted to trim the engine governor. There was also a P2 limiter set to 140 psig to protect the jet pipe and other components.

    That is where Military Operating Standards (MOS) come in, for they enable the commander to quantify the degree of risk and weigh it against the mission priority. With the single runway at Ascension and the multiple movements required to mount the Black Buck sorties the risk management process would have been applied to the fuel reserves required by recovering aircraft. I do not know what those figures were, or even if they differed from the normal ones, but suffice to say if the Vulcan had ended up in the water halfway back from Port Stanley and the sea around Ascension littered with half the AAR force then the mission would probably not have been judged a success!

    What also made it difficult was the fact that most of the Victors were limited to 110,000 lb instead of the usual 126,000 lb. This was due to certain wing fatigue issues at the time.

    It was certainly a way from the domestic site going towards the other side of the airfield. I can’t be more specific now. That was back in ’77. I was posted to ASF, did a short stint on the teams then into the tank bay.

    When I was at Binbrook there was a wreck of an AVRO Lanc/Lincoln on the base area. I did visit it once but I can’t be more specific as to type or reason it was there.

    I have read somewhere that the 302 is slightly longer. Not sure if it’s true.
    The 300 is longer than the 200, but then it does have a zero stage.

    You are correct, that is Sqn Ldr Dave Bagshaw.

    Maybe my user name will give some clues how I am so sure!!

    Are you he? The great and thrifty user of recce film?

    Good old ‘Baggers’? Didn’t he serve on II (ac) in the early ’80’s?

    No, I am not he! But I spent a very enjoyable 4 years on 41(F) Ops

    So you’d know abit about wet film then.

    The Canberra had a cartridge starter. 780 grams of cordite if I remember correctly. It makes a fair noise when it goes off.

    The rear fuselage section of XZ999 was eventually scrapped at RAF Laarbruch shortly before it closed. I tried to acquire it for a university for displat but was unsuccessful. I have no photo’s unfortunately.

    i wouldn’t say the starter cartridges on a canberra were particularly hard to change, they were a daily use item, so were designed to be changed easily.
    hunters also used the same cartridges as the canberra.

    I take it you have never changed one on a Hunter. The top one was abit of a stretch.

    small chance I can help – haven’t the slightest idea what an Akratork rig is though!

    PM inbound just in case

    Akratork rig it’s for checking/adjusting torque wrenches. I have a number of torque wrenches that have no scale but need to be checked. I did bid on a number of lots and got the lot.
