Minimans Are not TempestNut post #5 and MerlinPete post #9 saying that from their experience the Griffon makes the same sound irrespective of overlap and spanning the overlap value of a Merlin, at least from the figures given, 28-43-74? I appreciate that there are also many marks of Merlin. Presumably the overlap in the Merlin’s varies so does this change the sound?
Would this not indicate that fundamentally it is not the overlap that is producing the difference in sound between a Merlin and Griffon?

As far as I’m aware the valvetrain geometry stayed the same in all marks of merlin until the advent of the 100 series engines, my comment was perhaps not to well thought out more a musing after a morning bacon buttie!! But a cam timing with lots of overlap does produce a more crackling growl sound than a cam with less overlap and the Merlin has far less overlap than the Griffon which was the basis for my comment.

[QUOTE=David Burke;2157672]Creaking door -thats entirely true -what we don’t really know is if the prop was helping or hindering!

Webpilot – nothing to do with making a meal of anything – when John Romain put the Buchon down at Headcorn many were quick to indicate a ‘dead stick’
landing – clearly it wasn’t -the Merlin was still producing some power and the Sea Fury must have been producing something or it would have been in the field before the runway.[/QUOT

The pilot stated that he retracted the gear in order to make the runway and then at the last second extended the gear? If the engine was making power I would have thought a nudge on the throttle would have taken place? but obviously it wasn’t making power…..

I believe there’s one in Santa Rosa California being restored and is close to flight…………………

I have just got a copy of “Spitfire the History” by Morgan and Shacklady What a mine of information!! Also a book from the perspective of the man in the street on the Battle of Britain is Spitfire Summer by Peter Haining This is a really good read. and finally British Piston Aero-Engines and their aircraft by Alec Lumsden if your a petrol head like me this book is the most authoritative text on the different makes of Aero engines I have ever read and I’ve read a good few………………….

So the glider was not on approach to land but doing a high speed low level pass at what 12ft?
An official report by the Air Accident Investigation Branch (AAIB) found the aircraft was flying too low, the court heard. So there were more factors involved in this case than at first appears?
And yes in this case I think the risk was greater than I would have thought prudent.

Not to labour a point but has it ever happened that spectators have had the misfortune of an aircraft landing/crashing on there head’s on the approach path? Apart from one reply regarding a motorcyclist (who probably was just in the wrong place at the right time) I have never heard of such a thing?

So instead of being preserved, they are rotting in-place.

So tell me if he hadn’t bought them and left them to “rot in place” where would they be now? Oh I know my mums saucepan……………………………………………
