FW-190 A8 Emergency power timer

[Birdman]

Hey guys,

 

I came upon the following German document from 1944 that states emergency power can be used 3x10 mins with a 10 mins cool down in combat power:

 

My German is a bit rusty so that would be awesome if a German speaker that happens to see this can give the original document a quick read (it's not that long) and confirm it.

Thanks a bunch!

JaboRei => G-8 (C3 injection at 65 l/h)

Not the A-8!

 

Use prohibited with the high-alt blower/ supercharger!

 

3x 10min per use with a cool-down period of 10min at combat-power in-between.

I am not expert on 190s but is not the G8 almost identical plane than the A8? aditional armor, bomb racks etc but same engine?

It's based on the same airframe, but has some internal differences - mostly attached to the bombracks, guns and armor.

The emergency-power (C3 injection, also used in the F-8) is diferent to the increased boost solution as used in the A-8 fighters.

Same base motor (BMWD2 F 600), but whereas the G8 had C3 fuel "wet" boost (fuel injected into supercharger) in first stage only -  the A8 had a different "dry" boost system (used air rather than fuel) available for both high and low blower stages. A8 also had high performance fuel pump required to deliver higher fuel loads and 1.65ata in the 2nd blower stage.

 

The FW190A-8 used improvements from BMW801F research engine, and this motor was re-designated BMW801TU. This included the different injection system and higher performance fuel pump and also included higher strength drive components.

 

The ultimate serial production motor was the 2250 hp BMW801TS and new model designation to FW190A-9. The 801F under development never entered serial production but would have pushed 2400hp on C3 fuel.
