Creaking Door – I think your question is very valid – yes the larger round housing is definitely aluminium and you can see the casting mis-matches in places.

One thing – could it be considered as a lubricator perhaps based on the fact I like the idea of adjustable wicks and the aluminium housing is for containing oil. Then the narrow tube part would be upright and uppermost. We have not see the attachment on the end where the cast iron bracket attaches to – is that a sealed end for the larger part holding oil when the tube part is uppermost?

Then where the tube joins the large cast body, is there a gap there for something to pass through and for the wicks to touch? Or is it for a flame to share out at that small gap – too small for my liking and the tube part is not really setup for smoke gathering – I don’t know, wicks are usually flat ended and charred as they burn away aren’t they? Not formed over in a rounded end as these appear to be (better for contacting something passing through…?)

Sorry, just another out of the square sort of thinking, but that’s sort of what I am trained in… no idea is too silly when performing HAZOPS and engineering design and process studies…

He obviously hasn’t heard that wonderful song – or listened to the words either!!

In actual fact, it reduces the propensity to form a crack from the thin cut edge. It reduces the chance of vibrations flexing the original thin flat plate at that point and thus causing fatigue cracks through the vibration. The flange, in effect, does stiffen it to reduce the flexibility.

I’ve not been on here long but I do note a paucity in introductory comments and personal interpretation of the links you share – don’t just dump them into a new empty thread alone, please add some remarks to explain your intention by posting the outside link or comment. I have been on fora for about 12 years (cars, weather – 3 and aviation – 3) and find your posts rather empty or lacking in substance of your own volition.

Interesting that the Typhoons were operating from 41 through to the end of the war, they were never phased out and had become quite reliable and very effective at ground based offensive and lower altitude aircraft fights. The Tempests never supplanted the Typhoon.

Rolls-Royce were indeed in a race to get their version of the hyper engine into the Typhoon/Tornado as the pre-eminent supplier for fighter engines. Their version of two Kestrel V12 engines married together in an “X” configuration using a single crankshaft had several problems, some were based on whip in the crankshaft, some on the yoke and blade conrod clamping bolts failing, piston rings and a heap of failures they had not seen before. The engine was not a straight marry either, it needed a longer crankshaft for wider main and conrod bearings, and added counterweights etc. It was 42L and finally produced 1980HP in the Model V in August 1941 giving (0.76HP/cuin) (2850rpm and 2613ft/min) vs Napier Sabre engine 37L – 2250HP (3700rpm and 2929ft/min) June 1940 (1.10HP/cuin) which became an embarrassment to RR. Hence I think it became their desire to wrap it up at the end of the war after purchasing English Electric engine manufacturing which included Napier.

As it turned out, the radial engined Centaurus from Bristol hardly got into the war – provided to two squadrons as Tempest II’s late in the war in 45. This engine was huge at 53.6L (cf RR Merlin at 27L) and had huge torque which became a problem in itself during taxiing but did have good HP. Version VII developed 2520HP in ’41 (0.77HP/cuin) (2700rpm and 3150ft/min).

Sorry – a bit off topic with comparisons…

I certainly enjoyed reading The Cruel Sea at age 12, I remember seeing the movie on TV too. The other movies listed above I have seen as well, but quite some time ago. Can’t remember much of them although they were all moving and enthralling and some I have seen on TV as well. I also remember Paul Brickhalls historical books too – The Dambusters, Reach For the Sky and The Great Escape, all turned into movies.

I watched an old pre-war movie last night – well it was made in 1942 – and was an historical movie of R. J. Mitchell – the Supermarine designer of the Spitfire and the story of his adult life – passing at age 42 (June 1937) of cancer just after there was an approval for Vickers to build 310 Spitfires – his final desire achieved. Seemed quite factual with the Schneider Trophy races but ignored his work on a lot of his other designs for bombers and flying boats.

The First of the Few (1942) acted and directed by Trevor Howard and acted by David Niven.

I found it on YouTube.

Also there is a Typhoon at Hendon Museum as well… (photos c/- Calum Gibson)

I am not sure what difference there was between the Tempest and Typhoon radiators and thus the shape of the cowlings may have had slight differences too. This one is easier to get to though being arranged on the floor.

Oops! Sorry it is so big, stretches everything over the end of the page. Other forms of image store can offer different sizes to download.

Oh, there is a Sabre engine on a frame beside it on far left!! NB This is the only Typhoon on display in England that I know of.
