German Prop Pitch Lever

[IvanK]

Again Kurfurst as in the other thread:

Do you have documentation that indicates Auto was in general operational use before late 1940 ? If you do it would be great to see it.

i personaly hope if/when this will be changed, the 109's propeller pitch is still controlable with a radial axis (i have mapped the pitch on the thump wheel of my X52 Throttle) and we are not forced to map two new buttons , a "increase" and "decrease" propeller pitch button, espacially for the 109........

I've mapped the prop pitch to hat buttons on my CH pro throttle now instead of an axis (to be more realistic)

However in the current implementation you hit the switch once and the clock arms start spinning until they get to their new position. The movement is random and imprecise ranging from about 35 minutes to 40.You don't know where the hands are going to stop.

I wonder if it was like this in real life? It would be easier if the minute hands movement was proportional to how long you hold the switch down, i.e. let go and the hand stops moving. Of course this means the clock indicates the pitch you've selected and not the current pitch settings as it takes the prop a while to cycle, as shown in it's current form.

In the current form you don't actually know what setting you have selected until it stops spinning so if you hit it quite often it could go back several hours and you don't notice until it keeps spinning past what you wanted. If it's realistic then so be it, but it does seem wrong and not helpful for the pilot.

Does anyone have any information on how this worked?

Anyone have any contact with Russell Aviation Group who have that Bf109 E?

well, as long the CoD 109 has no thumb switch on its throttle you have to map these buttons on your Keayboard to get 'realism' i would guess

no offence !!

No you are right. I just don't want to map prop pitch 3 times. I'm banking on the E4 having the rocker switch.

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?

Pressing the two-way rocker switch up, the RPM increase , by pressing down RPM decrease. The original switch returns automatically to neutral.

From version E-4, the switch was replaced by a thumb switch on the throttle. The opening in the instrument board was sealed with blank sheet metal. Marked on the instrument board: E9.

The original pitch indicator "clock" is graduated so that 1 hour equals 6° of blade pitch or, 10 minutes equals 1°. The Bf 109E-3 VDM propellor can be placed in any position from 22.5° (fine pitch/high speed) to 90° (fully feathered) by 1-minute steps, equals 0,1° blade pitch.

Happy landings

As an aside. The range of the BF109E-3 propellor (CloD beta v14413) is from 12.00 full fine to 02:40 full coarse. ClOD BF109E-3 Propeller pitch comes with available positions in 5% increments from 0% to 100%, control can also be assigned to an axis that allows "finer" control at 1% increments. Assuming, that 10 minutes on the pitch indicator "clock" equals 1° you are able to adjust the pitch in steps by 5,6 minutes. I wonder if this equals a pitch range of 90°-22,5°=67,5°.

Hi Varrattu,

Thanks but I think you misunderstood me; I'm aware of the rocker switch and the lever and what they each do. What I meant is does anyone know how the switch, pitch and indicator functioned together, as a system, in real life.

The link I posted in my last post had the following quote in it:

"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."

This is how I imagined a system like this would work. The game doesn't do it this way, if you use buttons to replicate pushing the lever up or down, the clock hands start to spin on their own for a bit and stop at an arbitrary position. This is just from one push of the button and not holding it down.

In the example above this wouldn't happen; the length of time you hold the switch or lever in a position, is directly proportional to how much and how long the hands on the indicator clock move and the prop changes pitch. This sounds like you could have very precise control and know exactly what setting you are selecting and where the prop pitch is at that moment. You want 11:17 you can set it, try that right now, you'll be lucky to get 11:17 or even close. Even with a lever/axis touch it a bit and the prop pitch cycles through several degrees in one go.

If you try using the buttons in the game, rather than a lever/axis, the clock indicator is almost useless as reference instrument. With a lever/axis the clock is also useless but you can memorise positions in degrees on your lever.

Of course you can count how many clicks you've done with the buttons too but what's the point of the clock then? It doesn't sound like it's historically accurate according to my link. My link is copy from a post so I have no idea what the original source is so it's not hard proof. Hence me asking if anyone has any information on how this worked in real life.

Hi xnomad,

look here:

http://marseillegruppe.com/foro/view...f328cb9d3b84f4

the considerations / ideas in the a.m. thread are interesting but we should careful deal with in connection with CloD.

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

regards Varrattu

Sorry I'm confused, that's the same link I posted 4 posts above this one on this page. Did you intend to post a different link and pasted in the wrong one or was it an oversight?

Yep, it was an oversight
