A '109' returns to Biggin.
A quick post before I go through all my Biggin photos.
The stunning Aircraft Restoration Company Hispano Buchon which is now resplendent in the colours and markings that it carried some 42 years earlier whilst being flown for the Battle of Britain film. The Buchon was flown over the weekend by John Romain.

Of course it's a 109. It was built by Messchershmitt [bit early for accurate spelling] for goodness sake. Just because it was supplied to the Spanish as a kit of parts is irrelevant. If I bought a kit plane in the States, and built it here, it would still be named by it's manufacturer, even if I changed the engine in it. It's a 109, built in Germany, assembled in Spain. Simples.

I gather they were showing the footy at Biggin on Sunday.
I wonder if they got this '109' to do a flypast afterwards...
Great photos, look forward to seeing more!

why can't the Merlin be mounted upside down
You'd probably have to take a few inches off the prop diameter too, unless you were planning on cutting the grass rather than flying.

By no stretch of the imagination is that thing a "109"

Thanks GEERAM. Mis-information from a trusted friend!!!
Just looked it up for myself, and it was the HA-1109-J1l which had some Messerschmitt built airframes. Cheers.

So if most(all) piston engines are only able to be inverted for a short time how did Herrs Daimler und Benz manage to get their 601 to be mounted inverted in Herr Messerschmitt's little aeroplane? Presumably then the oil thingies were different.

Clearly part of an engine's is design is related to which way up it is mounted.
Despite most aero engines being dry sump an upright engine will have some sort of oil scavenge system from the sump where any surplus oil will collect by gravity. Turn it upside down and that oil will fall into the bores and pistons when operating and collect there when not running which has to be addressed and minimised in the design as neither pistons nor spark plugs like operating whilst filled with oil. An inverted engine must also scavenge oil from below the valve gear wheras an upright one will drain the rockers by gravity. The inverted time limitation on an engine will partly be due to these oil issues, but may also include hydraulic and fuel considerations (fluid pickup from tanks, cavitation of pumps, flow from tank breathers etc). Highly likely the Benz engine had an inverted limitation too. Perhaps someone here knows?

As for radial engines, perhaps they likewise were designed to operate at a given orientation, though given the reluctance of some to start, I wonder whether they ever really cracked the problem.
