German Prop Pitch Lever

I found this info on what I was talking about earlier, and it seems to agree with my ideas about the switch having to be held down. I have no idea what the source is but I think 'Wastel' was on the Ubi boards?

Hi.

This very interesting topic, who wrote the original post (schwarze-man), it is possible to contact him somewhere? I did not find it in my documents from the velocity of the propeller pitch accurate information.

But, if this true:
"The prop will adjust its pitch at a speed of 1.5° (degrees) per second for as long as the rocker switch is held and then stop when the switch is released. The movement of the pitch indicator is clockwise=fine,anti-clockwise=coarse. 1 Hour=6°,10min=1° so,1.5°/sec is 15min/sec or 1hour in 4sec! The range of the propellor is from 12.30 (full fine) to 08.30 (full coarse) and this equates to a pitch range of 22° to 46° "

...It is necessary to fix this in the game then! In COD (1.01.14588 patch), PP moving from 08:30 to 12:00 (21°) takes 58 sec! This means it, that PP moving speed 0.36°/sec. Compared with the value written early (1.5°/sec, or even in other documents 1°/sec), this huge difference, huge disadvantage (totally irrelevant, that PP are automatic or manual)! Some authentic source would be very good from this.

The speed seemed fine after the patch, but now the hotfix has definitely slowed it down. It can't be realistic now because, as you mentioned, it takes forever to move and is a serious disadvantage in a fight.

I've seen the degrees per second mentioned somewhere else, I'll have to dig it up again.

Yes, I remembered something like this. Great, thx.

I agree that the pitch ctrler is much too slow for any use in a fight.

4 sec per hour (needles) seems to be a more realistic value. 40 doesn't !

Otherwise the spring loaded lever (centered) works fine.

a speed of 3° per second is giving for a VDM propeller.
So, as one hour on the gauge is showing a difference of 6° of propellerpitch change , with the actuel speed of ~16sec for one hour , CoD is to slow indeed.

CoD = 6° in 16sec
real (according to linked book)= 6° in 2 sec

Which VDM propeller and in which aircraft ? Fw190 kommandgerate operation has a different pitch slew rate to the DB system that lacks kommandgerate.

i dont know. And wondering why the electric system of a VDM should work in different speeds with a BMW or DB601.

Anyway, if you choose 1° , 3° or something between per second, all is better than this 0,3...°

Maybe that the manual "D.(Luft)T. 3810 - VDM-Verstell-Luftschrauben Gerätehandbuch" can help us. But I didn't find anything of its content in open sources.

PS: Have a look at this
http://www.enginehistory.org/Convent...20Electric.pdf

From the book, The Messerschmitt Bf.109 by James F. Craig.
"Another departure was the propeller pitch control, which was mounted near the centre of the instrument panel instead of on the throttle quadrant, and the prop pitch indicator, which was in the form of a clock face, complete with hour & minute hands. Blade angles of the VDM electric propeller, which were infinitely variable from a low pitch position of 22.5 degree to fully feathered 90 degree position, were read as clock settings. About ten minutes on the clock face was equivalent to one degree of propeller pitch."

Schwarze-man has been responsible for a number of DB605 engine restorations he is about as "experten" on DB engines as you are going to get !

I did not know him, but im spoken with Kürfürst an afternoon, he said who he is. He tries to establish the contact with him (there were a couple of exchanges of e-mails with years before). But - according to these - he totally reliable source, there is not a claim onto an other document. Right?
