Detailed weight breakdown of DB 605A as installed..?

Kurfurst - do you have any charts with Hp as function of altitude for the 605A and A/S with 1.42 ata? Point me in the right location on your website?

Regards,

Think the AS Einbaumappe or some other doc has them, but I surely have some power curves for the AS versions. The Einbaumappe has a simplified power curve (ie. straight lines w/o the typical DB-curve shown, compare with DB 605A-curves which are more smooth and 'bent'.) showing output of

1435 PS at SL
1520 PS at 2100m
1200 PS at 8000m
925 PS at 10000m
810 PS at 11000m

at 1.42ata man. pressure.

In fact I had a semi-complete comparison handy, so I will post it here. It compares DB 605 series with the Merlin 61 (the only RR engine I have reliable/comparable power curves for). The similiarity of the AS and the M61 is striking. The powerful effect of GM-1 (that was subsituted with the AS/D engines in 1944) on altitude output can be seen as well.

If you have V 1650-3 and -7 curves, I would happily add them as well, after all, given your deep interest in the 44/45 air battles between escorts and interceptors, from which we have all fruited so far if I may add, I believe this is the core of the interest...?

Note :
DB 605G ~= maiden name for DB 605AM(= 605A + MW50)
From tabular data available for the ASM (output at SL and at FTH) it was relatively easy to estimate the other points. I wonder how accurate it is though, so if anyone has a 'proper' ASM curve...

Its also worth to take a look at this climb graph of the DB 605AM powered G-14 and the DB 605ASM powered G-14/ASM (both laden with MK 108 hubcannon and underwing gondolas). The climb curves should give a good idea of the power curves of the two engine.. http://kurfurst.allaboutwarfare.com/...SNplusMW50.jpg

Unfortunately, the G14/G14ASM performance paper from the Mtt Projektbüro, which seems to have such a curve for AM and ASM is in such a poor shape that the particular page is totally unreadable, almost completely black... :/
