How did the Rüstsatz system work?

Hello Leo,

Slightly off topic, but regarding the engine of Fw 190 A-8, WNr. 171747, your comment that “this aircraft was fitted with a BMW 801 TU engine,” is of great interest to me.

CEA 250 indicates that it was fitted with BMW 801, Motornummer 332379 (BMW F/M, München, Werke Allach, Hersteller code = jha). NOTE: CEA 250 actually says, "Q-2 or G-2" (it’s hard to read) but I have always assumed that it was just another of many errors in the CEA reports.

To that point, I have no records of any “Q-2” engines, and, the “G” was geared differently from the “D” and was used on bombers. Also, MNr. 332379 falls within other documented BMW 801 D-2 MNrn. Finally, I have zero references to any ”801 TU” engines at all.

If you have information or documentation showing that it was actually powered by a BMW 801 TU, I would love to update my files.
