DB-605AS/ASM power curves

Recommended Posts

Are there original German power curves for the engines? My brieth search returned only tables for SL and absolute full throttle altitude. It would be better to take a look at the whole altitude range and power ratings.

 

(I am beginning to investigate DBs :) )

Out of interest, why AS/ASM? Or are you just looking general information about DB 605 series?

There is power curve of DB 605 DC with MW 50 in JaPo's K4 book but i don't know if it's original german or not.

Yes, its for general investigation.

Sorry, these are not power curves, just some documents for aircraft performance.

Should be interesting as well - accurate power curves for the DB 605G (later re-named 605AM). Not only it shows the effects of increased boost, it also shows that when the boost is increased AND methanol-water 50:50 (MW50) boost is injected, performance increase also at above rated altitude, without any increase in manifold pressure, probably because of charge cooling.

 

The effect is also noticable on Bf 109K performance curves, where at high alttidue above the "MW abschaltun (MW switch-off)" point the performance drops a bit. MW injection was manually engaged, so even above full throttle height some modest performance boost can be gained by leaving MW 50 injection enabled.

This is from a post war Soviet book (secondary source, so not neccesarily accurate) power curve for DB 605 DC.
