Default Miss Shilling's Orifice

I found this and it is very interesting. I don't think we have this device installed on our Spits and Hurris?

Yes the Mk1 and Mk2 did not have the orifice... I think it only came along around the Mk5 if IIrc?

This still didn't entirely remove the problem, not until the Bendix-Stromberg carburater in the Mk IX was brought in.

Krupi is absolutely right. See the Spitfire in Il-2 1946 (Mk.Vb early for instance - neg G only sorted at full boost)

Did the brits not manage to create a fuel injection in 40-45?

IIRC, Rolls Royce considered the advantages and disadvantages and felt that the carburettor system was better for acheiving max HP from the Merlin.

The Luftwaffe fitted a FI engine (can't remember which model but one that was already in service in one of their bombers) to a captured early Spit and, from the accounts I read, Luftwafe pilots really enjoyed flying it. I am pretty sure It was sent to the USA at the end of the war but was written off in an accident.

Thank you for liking my Wikipedia article! I wrote it after a discussion on the UBI forums that had enough technical details and sources for making an article.

The "Tilly Orifice" (I can quite see the airmen of the RAF toast to that!) war retrofitted to all Fighter Command planes from late 1940 onwards. The device falls outside the Battle of Britain period in the narrow sense, though front-line units would have it during the late autumns fights against intruding jabos.

Unfortunately for red pilots this wasn't ready for BoB, good find though. I hope the devs have found this little gem when they have been 'poring over Spitfire data', for later periods of course. Also I hope that they spot the 12 and 15 pound boost variants of the merlin which I'm sure were available in the BoB.

the 12 boost is afaik already available (spit2a) even if the dial does not read it. I have some doubts that a 15 lbs boost spit ever made it to front line during BoB.
