RE: Vulcan at Hendon…….
Der, If your linking Black Buck with TFR, your on the wrong track. TFR was Terrain Following Radar, installed when the Vulcan was switched from high level nuclear bombing to low level penetration. Even though the TFR was an early model, a lot of the circuitry within it was still classified when the Vulcan was withdrawn from service. The Black Buck raids were high level conventional raids, so they probably never even switched it on!

RE: What about multi-row radial engines?
I’ve just found this – It’s Hawker Harrier J8325 with the Hydra installed at Filton in 1933!

RE: What about multi-row radial engines?
Hi Christer, The Hydra is one of those engines which defies convention. I’ve not got too much info on it, but it appears to have 8 “double” cylinders, that is 8 outer casings with a double sleeve inside each! Even more unusual is that it is a row of 8 Cylinders, as far as I know, totally unique!! Anyway there’s a picture below. You’ll be as confused as I am. By the way, it’s not a faked or doctored picture, the engine is on display in the “Power for Flight” display at Bristol Docks on the same Quay as the SS “Great Britain”

[updated:LAST EDITED ON 16-01-03 AT 08:23 PM (GMT)]You may also note that the main undercarriage doors, (the large forward square ones) are closed. This could not happen on an operational airframe, gear down, doors down. No other combination is possible. When I pointed this out to the museum I got a very feeble excuse about it being so that the public would not walk into them. But to an ex Vulcan man it’s really annoying when the aircraft is displayed in a totally impossible configuration. Aaahhhh! As for the TFR it was probably removed because the equipment within the unit was still at the time classified, and so some sort of fairing had to be fitted.

RE: What about multi-row radial engines?
[updated:LAST EDITED ON 15-01-03 AT 06:29 PM (GMT)]Hi Multirole, There were 18 and 14 cylinder 2 row radials, you can’t really have a 16 because that would mean an even number of cylinders on a single row and that don’t work too well. You can have a single row or 2 rows or multiples of 2 rows, but not a 3 row without horrendous difficulties in balancing the crankshaft. The Bristol engine company tried to produce a “double Octagon” (16 cylinder) engine called the “Hydra” back in the 1933, it produced 870 HP, it was test flown in the Hawker Harrier (the original version), but they never put it into production. So it’s not impossible to have a 16, or a 3 row, but it’s never been a road that was successful. If you look back at some of my earlier posts on radial engines you’ll pick up some more info.

RE: Turboprop engines in WWII?
[updated:LAST EDITED ON 14-01-03 AT 10:04 PM (GMT)]No Phantom II, your just dead right! A turbo prop is a jet engine where the gas flow is fed onto a power turbine to drive a prop instead of producing thrust. The problem was in the 40’s and 50’s that turbo props just did’nt have a sufficiently good advantage over piston engines to make them worth while. Also the big problem was the prop. A piston engine will accellerate and decellerate very quickly with throttle changes, which makes it very controllable. A Gas turbine engine likes to run at a fairly constant and high speed, which means you have to have a different type of propeller control on a turbo prop. These proved to be difficult to perfect, and it was this that really stopped the turbo prop from becoming an efficient powerplant until the late 50’s. If you take the Alliston T56 in the C-130 as an example, the engine runs at a virtually constant speed all the time, the power output (thrust) is changed by altering the pitch of the prop.
RE: Air museums free entry, good or bad?
Firstly, consider yourself lucky. We only have one aviation museum in Scotland, and that’s not free. It seems that Government funding does not extend across the whole country. Ah! the joy’s of devolved Government! I personally think we need to encourage people to take an interest in aviation, particularly the younger generation. When I was a wee boy, we had very little spare cash, and despite the so called affluent society, I’m sure there are lots of folks who really can’t afford to visit museums as often as they would like. Museums of course also have to employ people, so I have no doubt that having a known budget to work to makes the whole process of running the place a bit easier. So instead of spending millions on rebuilding rusting old piers that nobody cared about until it fell into the sea, or maintaining millenium domes that no one wanted in the first place, lets use the cash to make museums free for those who would like to visit them more often.

RE: Warwick
Hi Guy’s, Thanks for the info. How about we give Merlins site a go for thing’s purely Scottish, then we won’t be boring our English chums!

RE: Help wanted on RAF memorabilia
OK now for some more speculation! The wings probably mean that lofty was a pilot. Most presentations relate to what the individual did. If “Lofty” had been an engineer, ground or air, the presentation would have been more likely to have been a piston or something of that type. Kev also makes a good point on the informality of the inscription. Presentations from Airmen to Officers and vice versa are usually much more formal with rank included. My guess would be that “Lofty” was a SNCO pilot or WO pilot.

RE: New Curator at East Fortune
Hi Alastair, The last time I saw my Bone Dome it was in a glass cabinet marked new acqisitions near the entrance to the main Hangar. It was a standard Tornado type helmet, green with the white cross on top.

RE: Scottish
Der, in the book you mention, does it give the identity and details of the Warwick that went down in the Culbin forest? I’ve attached some photo’s of the crash site.

RE: Help wanted on RAF memorabilia
[updated:LAST EDITED ON 10-01-03 AT 09:44 PM (GMT)]OK I’ll start the ball rolling on this with a guess at the date – pre 1952. Two reasons for this. The clock face looks very much like it has a luminous dial – good old radio activity like the aircraft instruments of the day, secondly and more to the point is the type of crown used. The crown used is the type used on RAF badges up until Queen Elizabeth came to the Throne, the modern one is different. The badges below will illustrate the difference. The 21 Sqn badge is the pre 1952 crown, the 12 Sqn badge is the post 1952 crown.

RE: New Curator at East Fortune
[updated:LAST EDITED ON 10-01-03 AT 09:05 PM (GMT)]I’ve not met him yet. But I’m intending to contact him soon to see if he will allow me to use the presentations room to perhaps start doing some technical presentations and allow access to the aircraft as part of that. I’d also like to find out if they ever intend to use any of the items I donated. So far the only item I’ve seen on display is my old “Bone Dome”. I’m hoping to get a more positive response than I did from the previous incumbent!

RE: Congratulations!!
………..and for you Steve, A JP you’ll probably recognise, it’s XS209 alias 8409M, one of the fleet we used for engine changes and ground running, altogether much easier than the Pembroke – and not so much fun!!
