prophetic more like……………
wow 3 movies!!!
naww, this is a deliberate ‘spring clean’
That looks too clean a break to be carbon fibre failure, that looks much more like the bonding of 2 sections has failed
i was going to put somthing similar, since there are no broken fibres, and the nose isnt hanging on by fibre threads, but the text did say that it didnt break at a joint……i suppose it could be a layup joint in the mould (layups with no overlap?!) which isn’t neccessarily visible on the finished tub.
it would be good if it did……nice to see one at bristol…think they look great!
i remember reading somthing about vibration fatiguing in the tail cone from the propellors as being fairly critical…..I believe burt still uses his. Cool airplane, don’t know whether I would want to own one purely on the basis of maintenance costs.
Septic,
I’d love to find out just how many structural engineers have any professional familiarity with AVRO’s finest…….bet I wouldnt even have to take my socks off.
What I can’t understand is the massive additional £ 695K that Marshall Aerospace required, where did all this extra money go to, I’m pretty sure it didn’t go on their engineers salaries!
The other point I would like to pick up on would be wether the overhaul by Marshall Aerospace was agreed at a fixed price or not, there should be no grey areas, the statement
‘because we set expectations with MA from day one that the project was in essence a fixed price one’.
This word essence, I would like to see how this was worded in the contract.
I currently run a small business and have learn’t from bitter experience to allow for the unforseen when we provide a quotations for jobs, This is common sense and I’m sure Marshall Aerospace would have done so within their original costings, its not as if the Vulcan is new type or some technological break through, its a know quantity that is relatively low tech.
……………………………
Septic.
1. fully agree septic, i would have thought that a cisco director would have nailed the contract down a bit better than that!
2.I don’t agree thatthe vulcan is a known entity within the engineering world anymore. there will be few people in the engineering world who will be familiar with the calcs of this aircraft…perhaps a few more on the maintenance side, mainly centred around the existing aircraft, but in the current commercial world I would be interested to see if the calcs still even exist, let alone anyone who wrote them still being around (and having to deal with other peoples hand written calcs (for fairly modern projects!) at times, I would’nt want that job!)
since my last post on this topic, I’ve been working on the A350 project, and it has done nothing to convince me (and quite a few others) of the ‘benefits’ of carbon wings, as we are forced to design them at the moment.
As you have seen, the A350 comes in a number of versions suited to take on both the 787 and 777.
I’ve been through a concept trade-off between composite and metallic ribs, and seen composites loose, and I’ve seen the product of new machining technology that can reduce the weight of metallic parts making them truly favourable over composite components.
Still, if Steve Udvar-Hazy wants composite aircraft so will every other airline (as he appears to speak for the airline world (and be bezy mates with boeing)).
Having seen the photos that are out, on centre wingbox construction, there are a couple of differences between the A wing and the B wing.
Rumour has it that the B wing is not out of the woods yet…….and of course, they’ve had to scrap a whole fuselage section because of deficiencies in one small area that was not or could not be repaired (and this can still happen with whole wing skins given the manufacturing process (automated my ar*e).
My perspective and knowledge has changed and I would probably not write my previous posts like they are, if we went back and did it again, but the overall opinion I tried to put across still holds.

thanks for the images Archer, they will be useful!
T6Flyer, I’d love to see what you’ve got on the norseman!
thanks for all your help!
all it is is one aircraft family taking on 2 competitors and eventually replacing part of the existing product range, it seems that a few people are finding this hard to grasp.
check your email!
can i get one from you direct then? 🙂
thanks one-and-all!!
I am plannin on making a very detailed flight sim model, and also going to try plucking up the courage to scratchbuild it in 1/32 or 1/24th!!!! so all and everything is going to be useful!!
I have to go down london way in the next couple of weeks, so will give peter elliot a go, is he on these boards?
Thanks again!
