Ayahuasca, you beat me to it. that westland Wyvern looks like an intresting aircraft. i also hear that the US Navy is lookin to use similar aircraft to support the US special forces......

I remember reading about this and being fascinated by it in the late 1980's as a lad.
The Ultra High Bybass Ducted Fan engine. I think I even have the cutaway that featured in Flight International at home somewhere.
They were supposed to be the next big thing in aircraft engine design but sadly didn't get off the ground (so to speak).

Shot taken at Farnborough 1988 or 90. I was working about half a mile from the runway approach and the noise of that thing was extremely distinctive. It was surprisingly loud and sounded like a butch version of a Beech King Air.The Ultra High Bybass Ducted Fan engine.

I read somewhere that they canned the ductless turbofan engine because it was soooo bloody noisey, and fuel was cheap so they stuck with ducted. Apparantly theyre now back testing them, because they're upto 30% more efficient then normal turbofan engines. They're hoping that with better computing power then can design them better for less noise, and the fuel savings right now would be very well received!

the UK was only 3 years behind the US in developing the H bomb so the transfer of knowledge is unlikely to have been as one way as is generally assumed.
I dont understand the last bit: three years' worth of development is a long time...If the Americans had a working device, what significant information could Britain contibute if we were 3 years behind?Given the incremental pace of development once two stage devices were created I would argue that it is unlikely that the US were greatly ahead in bomb design.
What the British program did achieve was a working two stage device on a fraction of the budget the US threw at it and with significantly less testing. Hence what US got was the knowledge of the techniques the British had used to get more bang for their buck (and the recipe for nasty stuff like VX nerve gas) the British got the economies of scale of being part of the US program and getting the US to do all their testing for them.

I've heard about this too, I'd love to see this engine in operation.I was having a look through wiki and it mentions that the Russian have been working on an cargo aircraft (Antonov An-70) which uses ducted fan technology, however they haven't found any buyers for it yet.
Rizzo, awesome pictures. I had no idea there were any 'proper' style flying boats left.
A bit of internet research reveals it is a Martin Mars.

I finally got around to watching 'Engineering Britain's super weapons' last night.
The Valiant stalling on the escape turn after dropping Grapple X (Not to sure) must of been interesting on the underpants. There was some pretty amazing videos up close of the Valiant and Vulcan.
One of my favourite pictures of a Hercules
Was looking for some Hercules conducting jet assisted landings, but I cant find any. I may of read/imagined they were trying to see if the could land Hercules in football stadiums.
In fact i must of imagined that.

These are still being builtA bit of internet research reveals it is a Martin Mars.

This has been in limited production in recent years
As is this
So the large flying boat isn't quite extinct yet.

I love big flying boats, they really do look fantastic.
