You guys just don't get it. You don't seem to understand decks and overheads, and ladders and bulkheads and port and starboard either.
If your soon-to-be victim is coming at you from dead ahead, he/she/it bears 0 degrees relative, thus zero aspect. If 180 aspect, better check your six!

The Allisons in the P-40Q (and some other late war aircraft) had a crankshaft with 27lbs worth of counter weights added.
Ask ShortRound6 or GregP, but I bet you'll find those were put there not to ballance power strokes, but to reduce bearing loads as individual cylinder power outputs climbed ever higher and pistons and conrods heavier. The "natural ballance" of any even number cylinder bank refers to power stroke balancing, while single cylinder mass ballance in rotary motion is where crankshaft counterweights come in. The torsional loads on a long (hence more flexible) 12 cylinder crankshaft are massive.So much for the natural balance of V-12's.
My dad!!! He loved the Spitfire but it was not a good tropical fighter. He liked the Kittyhawk but it was like flying a truck compared to a sports car. Given the conditions at Milne Bay, it was pretty good and tough. It was a much roomier cockpit than the Spitty.Did your grand father have anything to say about the Kittyhawk?
I only just found your reply! Many thanks for it. I'll have a good read of it. I'm not sure how dad got that copy being 'Most secret'.Attached is the full file that your document was extracted from and you will note two differences. Whoever copied the pages you posted did a far better job than the National Archives of Australia when they copied the file, and there is no note on the bottom of the first page.
Incidentally Sydney Cotton also designed the famous WW1 Sidcot flying suit and had a lot to do with developing aerial photography
I think I commented but, its unlikely anything beats the Spitfire in that matchup. The SPitfire has so many versions, too, that I can't imagine either one beating the SpitfireHow good was Zero against famous Spitfire or German FW 190?
Can a Zero beat them any chance at all?
If you read through all the past discussions on this and other threads on this forum, you'll discover that the first confrontations between Zeros and Spitfires turned out disastrously for the Spitfires. The Spit pilots tried to use ETO tactics against the Zeros and discovered to their chagrin that Zeros were NOT MEs or FWs. They were far more nimble.I think I commented but, its unlikely anything beats the Spitfire in that matchup.

Nothing can do a low speed vertical loop as tight as a Zero. Ditto a tight turn.Yep, once the Spit has bled off it's speed in a turning fight, the A6M has it right where it wants it.
We could always start a thread with something like "GM 153 versus BMW M10" and see what happens!Damn, a small drag racing discussion a few pages back and I missed it.
You don't suppose there's a relationship between this and the fact that Allisons could handle oversquare (high MP, low RPM) much more smoothly than Merlins, thus giving them superior long range cruise efficiency? (Guadalcanal->Yamamoto->Gaudalcanal)Ask ShortRound6 or GregP, but I bet you'll find those were put there not to ballance power strokes, but to reduce bearing loads as individual cylinder power outputs climbed ever higher and pistons and conrods heavier.
