    Hi Spock and all, in case you haven’t found them yet, here are the pages from the AP showing the jacking points.

    AP-101B-1902-1A, just over half way through.

    Does anyone know the weight on the nose wheel when the Vulcan in in a three point attitude? Someone from the Vulcan to the Sky team must surely know from C of G calculations? It would give NEAM an idea of the load lifting ability of any crane used to lower the aircraft.

    Hi, if you’ve not already done it, a quick back of the envelope calculation.

    According to the AP, the empty weight of a fully kitted out vulcan is 100,757lb. Yours might be a few hundred pounds lighter from removed equipment, but then you’ve got the bomb rack and front fuel tank.

    The C of G is between 142″ and 156.9″ aft of the datum.
    The nose leg is 175″ fore of the datum (roughly)
    The main legs are 180″ aft of the datum.

    Assuming 319’s within the C of G limits (once the snow’s melted), the weight on the nose leg will be between 2,977kg and 4,898kg.

    Does that sound sensible?

    Sven, good stuff. If you also know the height of the main gear, you could work out the c of g in the tipped position relative to the wheels and therefore roughly how much down push if any will be required to get it started.

    Hopefully, once the snow’s melted, you won’t need to push down at all.

    Of course, feel free to post it wherever.

    It’s a rough estimate, you might want to check to see whether there’s an official version in the APs. Also it only holds if you’re within the CoG limits.

    Last time I spoke to him (November/December time) he was still working towards it (certainly ground running, not sure about taxying) but hadn’t yet run them.

    It’s looking fantastic now, worth a visit for anyone in the area, and I believe there’s another night photo shoot coming up. An ideal excuse to make the trip if you live further away.

    I think its a credit to the design team that the crane only registered 1.5tonnes at any one time. Even with a lot of kit removed the C of G must be all but perfect.

    If she was within the C of G there would have been at least 3 tonnes on the nose leg. That there’s less shows that the C of G must be aft of the rear limit.

    Perhaps there has been more equipment taken out of the nose than the tail.

    Great stuff! I can’t remember, did the Gannet guys manage to sort out the issues with tools? Seem to recall they were being held back somewhere by lack of the right spanners…

    They were looking for the spanner to remove the propellers back in 2012. I think they found it a few months after asking for it, and the props were taken off successfully.

    Agreed but, I make the point that 60 years ago, during what seems now to have been the golden era of British aircraft engineering and production and given the variety then in service, we apparently did so much more with so much less. Or, was that an illusion ?

    I think we did more with more back then, according to this graph (which I’ve not checked in any way so happy to be proved wrong):

    Edit, the part number is Dunlop DR0325T. As far as I know they are only common to the Sea Vixen and are about three and a half feet in diameter.

    Or if anyone happens to have a spare buccaneer tyre they could part with that would be even better.

    No news on the tri-star fleet??

    According to this article a company is looking in to buying them for operation. The one in the static park at the last open day had a US civilian registration painted on.

    And a press release from the company:

    There is no connection. It is blindingly obvious, even from their own photos, that the rivet lines do not match the structure they claim to have matched it to. A scam, pure and simple.

    I wondered that as well. Also, as it’s torn off on one side, how could they know how big the whole piece was?

    Here are a few more photos of it.

    Very glad it ended well for the pilot. I dropped the camera when he crossed the threshold with his gear back up.

    Not a 100% certain answer, but it looks a lot like the Halifax fuselage tank held at NEAM (now NELSAM). There seems to be an older thread where someone’s found something very similar and come to the same conclusion.

    Does anyone at NELSAM/NEAM have decent photographs of the tank?
