Re: List of DB 605A engine construction numbers?
No takers? OK, fair enough this is not all straightforward.
So, first-off, the engine here, Werke Nr 69010 was a DB 601 E, you can tell from the engine database. Daimler-Benz have used this slightly earlier info but, it is still relevant as it had the same 200 hour Grunduberholung planned life with 100 hour Teiluberholung as the DB 605 A-1. However, this lifecycle was rarely achieved, as we can tell.
The horizontal lines of data are as follows:
Top line, is the type of overhaul Teil (T) or Grund (G) and the workshop code.
Middle line is the hours since previous overhaul.
Bottom line is the date of overhaul.
Therefore, this engine flew 18 hrs from new and had a Teiluberholung at Werke 3552 completed in Jan '41. The engine then flew 78 hrs before a Grunduberholung at Werke 3652 completed Sep '41. It then did just 12 hours before it's next T service, after which it managed 51 hours before a G service. The engine is now into it's next nominal 100 hours before another T service.
So, this information shows a great deal. Not least that the flight time between overhauls was very much lower than the nominal. This is not surprising, and it is likely that the reasons are damage, engine partial failure or management decisions to incorporate upgrades/modifications.
The lower section of the Schilde is for recording modifications and other work, recorded this time with: a code for the mod, the Werke and the date, again in a column of three blocks, eg 101-3652-842.
Overall, the "Life" of the Motor is consistently related to the Grunduberholung cycle, ie 100 hrs for a 0-series and 200 hrs for a 1-series, with a Teiluberholung at half that period. However, other combinations of engine build standard could limit these nominal life figures. For example, the previously noted problem with thin-crown pistons attracted a limit of 75 hrs and there were other combinations. It is interesting that the engine Schilde does not seem to carry the life limit for the next overhaul. It is presumed that information was recorded on the engine record.
Cheers
