German Constant speed props

Many Thanks Taz. This makes much more sense.

With best wishes,

Hello YavorD, and Taz, Rammjaeger and Scott ;-),

i think you are right, the propellor (or screw ;-) ) does not always reach the intended revolutions of the engine on a climb (hanging on the prop), in high altitudes (because of the engine performance decreases - nothing to do with the propellor), or even faster in shallow glides (overrevving because of the wind helping turning the prop), but those conditions do not affect performance, security or reliability.

This "Turenaufholen" means the Reaching of tours (as if the prop trys to keep up with the engine revs), or better revolutions of the prop trying to reach the engine revolutions, but being affected by varying conditions. It is really a strange word in this context, implying different speeds of prop and engine, which is not meant here.

Greetings,
Catfish

Catfish is right that these lines were even hard to understand in German language but I think the explanations above hit the nail on the head.

By the way "übertouren" (over-revolving) in dives was a very dangerous thing for another reason. It could cause the synchronisation gear to fail if the pilot fired the fixed MGs for an attack in a dive.
