Title: DB603C
Post by: moot on April 14, 2009, 07:24:44 PM
Has anyone heard of such an engine?  It seems to be the source of "1900hp" quoted in various books/articles as the engine specs for the Me 410.

It's "G" not "C".

Otherwise, I know no more.

i found this:

    * DB 603G; DB 603A mit höherer Verdichtung; 100 Oktan C3-Treibstoff, Entwicklung 1944 gestoppt

    Startleistung: 1395 kW (1900 PS) bei 2700 U/min

maybe this C of the spezial 100octan c3 fuel made the confusion?
cant find any c model only one page shows a c. and says 603A-N till 2400hp but noting more :-(.

Er... I heard about this engine having been installed in several (just enough for inclusion into AH, as it were) 109F's.

Chris, Mazz, can you give your sources for these?  It's under the "experimental/planned" category, so there'd have to be concrete evidence it was used in combat...

A few 109F fuselages were used to test several design features of the Me 309, which was to be equipped with the DB 603.

"Entwicklung 1944 gestoppt" = Development halted in 1944. Prototype engine.

Both the A and B series Me 410 were powered by the DB 603A or DB 603AA with a rated power of 1,750 metric hp. Some of the heavy fighter versions had GM1 injection (replacing the gun barbettes) increasing engine power at high altitude; there might have been MW50 injected versions too, but the majority if Me 410's had neither.

I was being facetious when suggesting that an early-war, light-weight airframe be equipped with a late-war, high HP engine, in game.

But basically  that's exactly what happened with the 109: Going from a 680HP engine weighing 440kg  in the pre-war 109B-1 to a ~2000HP weighing 730kg in the K-4  ;)

Granted... but it appears as though the engine in question, installed in an F tub, would likely give an F15 a run for its money in as far as ballistic acceleration.  :D

1900ps != 1900hp, maybe that's the cause of confusion? I've read a few things that mixed up ps and hp over the years.
Title: Re: DB603C
Post by: moot on April 17, 2009, 01:53:13 AM
PS = metric HP.  1900PS is ~1874 "international" horsepower. On B4 fuel and in metric HP, on WEP, the 603A is supposed to do 1750 @ SL and 1850 at ~7000ft.  The 603AA is supposed to do 1670hp @ SL.   So it wouldn't match any other figure I've seen, other than the 603A @ ~7kft.  It's gotta be that experimental unit "C".

1 PS = 0.9863201 HP

1,900PS = 1,874HP

Substantially no difference unless you find yourself flying in the Alps with a map and a stopwatch in a plane with no windows.  ;)

i only found this in my books about the DB603 A,C,E

DB 603
Leistungsstärkere Vergrößerung des DB 601, der in verschiedenen Varianten bis Kriegsende gebaut wurde.

DB 603 A, C, E
Version mit 1750 PS Startleistung

i try to translate-
The DB 603 is a ubgraded DB 601 built in diverent variants til end of war.
The DB 603 A, C, E are versions with 1750PS.

sorry i cant find any more in my books.

Would say the 603 was more than just an upgraded 601. The 605 was more of an upgraded 601.

cc thats true. my boock says the 603 is an "Leistungsstärkere Vergrößerung" (the same as 601 but biger with more power) of the 601.
and the 605 is an technical ubgraded 601.
