Great documentary about the Battle of Britain

I didn't hear anything about out turning..

But the facts were, it could out dive out run and out gun the spitfire..

The ME 109 had one major advantage over the Spitfire and Hurricane; it could 'bunt' and pull negative G without the engine stalling. A Spitfire or Hurricane had to roll inverted before diving, to maintain positive G on the carburettors and keep fuel flowing to prevent the engine from starving and stalling.

Rolls-Royce did produce a modification (Mrs. Cottle's Orifice I believe it was called) that went some way to helping the problem, however, they were never able to eliminate it as the Merlin didn't have fuel injection, as per the 109's Daimler Benz engine.

Her name is Tilley and Merlin it did get fuel injection. The injection was single point, not multi point as on the DBs.

As far as I am aware, the early Spitfires (as depicted in CoD) weren't fitted with the modification, so that's why all Battle of Britain era film of Spitfires and Hurricanes shows them rolling onto their backs before diving, to prevent fuel starvation.

It may have been a fuel pump issue rather than carbs, you could be right; to be honest, I'm not that much of an anorak about the RR Merlin engine.

Tilley's Orifice was introduced after the BoB. Sixty series and later Merlins got the fuel injection.

It was a combination of carb and fuel pump. The lean mixture cut out was a minor issue. What was the major issue was the rich mixture that flooded the engine. This was because the fuel flowed into the card unrestricted. Tilley's Orifice restricted this flow of fuel.

Sorry to be a pendantic pain in the rear, but the 'Me' designation is a misnomer. It was always called the Bf 109.

Is that so. Then why do I have a factory drawing for the 109 wing that is titled 'Flugel Me109F, Me109K' and another factory drawing that is titled 'Flugel Me109F, Me109G'?

It seems the 'me' designation is acceptable after all. I just did a fair bit of research and it seems either the 'bf' or 'me' designation is acceptable.

Me is shorthand for Messerschmitt as Do is to Dornier, Ju to Junkers, FW to Focke-Wulf and BV to Blohm & Voss, etc. They were (and still are) valid shorthand for the German manufacturer's names.
