E-series:
If you speak of the DB 601A-1 or Aa then please never use the 1100PS for the A-1 or 1175PS for the Aa as this 1-min-rating was not available in the Bf 109. The A-1 had max 990PS and the Aa 1045PS (Take-off Power, 5-min-rating)
That`s half-correct. The DB 601A and Aa had 1100 and 1175 PS output cleared for them at the start of the war, but that was a 1-min special overload function, appearantly for low-level flights and/or takeoff purposes.
Mike Williams has claims on his site stating otherwise, but those are fairly baseless, using selective quoting of manuals. Even French papers of captured Emils from 1939 note to 1100 HP rating. Speaking of it, the absance of Aa powered variants or the claims regarding the DB 601N are baseless as well.
The G-10 used the 605DM, later 605DB, the first with ~1700PS, the latter with 1850PS (later reduced to 1800PS due to malfunctions and overheating), all with MW-50). the G-10 also had the new wooden tail with larger rudder as standard.
The G-10 used the same engines as the 109K.
a, DB 605 DM, with 1800 PS output at SL, at 1.75ata.
b DB 605DB/DC, the same engine as a matter of fact, but it could be set for either DB or DC configuration for B-4 or C-3 fuel.
ba, When set to DB, output was 1850 PS, either with B-4 + MW-50 or on C-3 fuel alone.
bb, When set to DC, there were a number of possibilities:
bba, Set to 1.98ata, running at 1.98ata with C-3 + MW 50 : 2000 PS
bbb, Set to 1.98ata, running at 1.80ata with C-3, no MW50: 1725 PS
bbc, Set to 1.8ata, running at 1.80ata with C-3 w/woMW50: 1800 PS
The DB and DC merely differed in the latter having more power at below rated altitude (6000m static), due to running on higher boost.
The K-4 reached a maximum speed of 715 km/h (~445 mph), a prototype with a special prop reached the well-known 728 km/h (~452mph)
Yes, that`s correct. Max. speed of the 109K was 715 km/h using the serial production propeller, either at 1.8 or 1.98ata (the latter had extra performance below rated alt though) and tests were made with thin bladed propeller resulting 727 km/h, and swept back propeller resulting 741 km/h - but these latter props were not standardized before the war ended.
Re: 109K wooden wings, I think the idea of wooden wings to simplify production came up with the 109G already and was tested, but it was found that wooden wings do not yield a reduction in labour hours needed to produce them, so it was dropped. As for the K-6, there were wooden
mock ups made, but I don`t think it was meant for production, only easy-to-produce 'models' used in the design phase. Even the Tiger I had wooden mock-ups.
