Bob and I have been in touch with each other since the early days of Aviation Archaeology which is now over half a lifetime away. Would still welcome sight of your negatives after your house move.
Sicobra its a shame you could not share your images with us to ensure authenticity with our paint scheme which will be unveiled to all in the coming days.
Beaufighter II’s also flew with dihedral tailplanes, the flat tailplane was preferred for the night fighter as it made the aircraft unstable but more manoeuvrable, Google Beaufighter II images.
Other issues include radiators and a totally different propeller, Dowty no less.
Everything is possible, simple, no!
PL983 at East Midlands many years ago.
When an aircraft propeller rotates under power it grabs air to move forward and its efficiency depends on the density of the medium, the greater the altitude the air becomes less dense the less efficient the propeller is. Even so the bending moment on the propeller blade is in a forward direction.
When producing no forward thrust the bending moment on the blade due to drag is in a rearwards direction.
Substitute a more solid medium , then for one revolution under power the blade can move further forward than it does in air and the bending moment increases in a forward direction. No power it grabs nothing and bends backwards.
“At 1345 hours on November 11, 1940 two formations of Italian bombers escorted by fighters were intercepted by the RAF off the Suffolk coast. Approximately eight German and seven Italian aircraft were brought down in the sea, and three aircraft made forced landings in Suffolk, including a Fiat CR.42 biplane – the pilot was arrested and taken to force headquarters at Ipswich.
Sergente Antonio Lazzari of the 85a Squadriglia crashed with MM6976 (‘16’) near Corton Railway Station and was taken prisoner.
In response to your question Jason, still looking for bits, unlike P-51’s hard to find.
Markings are of this aircraft, taken in Belgium probably just before it’s last sortie to England.
Colour shots not being shown yet, keep you guessing.
Markings are of aircraft brought down on the same day as the aircraft in the RAF Museum.
Photos taken yesterday.
A taste of things to come!
I messed with a lot of a/c in the Royal Air Force, Canberra’s, Hastings, VC-10, Belfast, Whirlwind, Wessex, Chipmunk, the BBMF a/c, etc.
The most fun time was the Beverley in the Far East, as others say, I’d better get my coat!
Who needed a nav on the Beverley, it was so slow and low you could read the street signs. One trip I was on took two days to cross Australia.
Seems we have a bit of thread drift.
The size of the sump I guess would be to do with the horse power of the engine and the amount of heat that would need to be dissipated by the oil. More heat more flow.
On the Centaurus fitted to the Beverley we always lost a lot of oil on start up, it had drained to the lower cylinders whilst stationary. On the odd occasion it would be necessary to remove the lower spark plugs to drain the oil. Consumption not a problem as the aircraft was fitted with overload oil tanks and the oil could be pumped by hand to each engine.
Cruise power was not that high, I think ECB (economical cruising boost) was +4, but flight times could be long, in the Far East ten and eleven hour legs were not unusual.
On the Hercules 216 fitted to the Hastings I don’t recall the problem.
I did consider the R-2600 fit but it just does not look right. Same with the Merlin fit.
Just to clarify the Hercules position on the Beaufighter, answered in previous posts.
The later Hercules will fit even though they are longer and wider. Some years ago we designed a replacement engine bearer to cope with these problems. Moving the engine further forward by three or four inches was not the major problem. The later engines have a very large sump which gets in the way of the bearer cross bracing. The early engines have half the number of induction pipes as they are “siamesed” and a much smaller sump which makes life easy. The early engines have a carburettor whilst later engines have a Claudel Hobson injector.
We are currently helping an Australian company with information on the overhaul of early engines.
Can anybody help with manuals for the A.I.T 132 MC, & M , A.I.T 122 MB & M,carburettors?
