You'll be eating those words someday here soon :D

You must adjust those settings for usage with my suggested ratios, otherwise flank speeds will be sensibly lower that the expected, especially for electric propulsion. Reason is that my AheadFlank settings are not equal to 1 :yep:

Really? I thought that one of TDW's patches had fixed it. Anyway, the point is not if we can set electric propulsion on surface or not, but whether game takes conning tower's and external equipments friction into account or not :03:

So, as I see it, I think we (I) don't need to further edit this mod and Fifi has final variant now :yep:
Thanks Gabriele :salute:

EDIT: oops.. didn't see your last post.. anyway, it worth to wait what Fifi will say after tests..

I'm ready :D, whatever you say :D

Don't worry, tomorrow I will check again my sources and my calculations, and I will make a new post which will correct any possible mistake by me and will make things more clear :up:

Bon apétit! :D

Okay, we can wait your final verdict while Fifi is testing current version :yep:

:har:

First test (with latest patcher) with CSP Magui UI in my career with 7a :doh:

3m/s wind calm sea
In Knots

Diesel
- very slow 5.8 Back 6.9
- slow 9.2 Back 8
- standart 11.2 Back 9.5
- full 15.5 Back 12.1
- flank 16.3

Electric
- very slow 2.8 Back 3.2
- slow 4.4 Back 4
- standart 5.4 Back 4.8
- full 7.5 Back 6
- flank 7.9

Reading from Magui left console + gauge inside main room (down right to the knokle guy - and the speed dial, but not that accurate...)

Submerged, i'm going faster backward @ slow speed :o :06:
Where can i read my RPM?

EDIT:
Other test this time using single mission and still 7a ---> got other values!!...but still submerged backward faster...
Don't understand...gonna reinstall fresh NewUIs + mod list on an other install, and see difference with Magui...

RE EDIT: NewUIs is same values...not any better.

Ok, found where to read RPM :D
Forget about above post values...

Latest tests with VIIa still gave me faster speed backward than forward, and i don't know why because in the cfg file, backward ratio is a bit less than the forward :o

Latest speed in Magui:

Diesel
- very slow 5.8 Back 6.9
- slow 9.2 Back 8
- standart 11.2 Back 9.5
- full 15.5 Back 12.1
- flank 16.5

Electric
- very slow 1.4 Back 1.8
- slow 3 Back 3.2
- standart 4.2 Back 4.8
- full 6.5 Back 6
- flank 7.5

What do you think? :hmm2:

I think it's really weird :hmmm:
Maybe Gap could answer..

Maybe the game is using different calculations for forward and backwards speeds? :hmmm:

I will post soon a chart with the target speeds and RPMs that we should aim to. From there we can start doing our adjustements :up:

Yeah, something has to be wrong somewhere...
At first, i thought it was coming from Magui, but no.
In second time, i thought it was coming from patcher not reading correctly or screwind up values, but TDW make usally good work, so...i don't know.

Seems the best way :up:
Even if Cfg file values seems a bit weird after, goal is to get the right speeds ingame :yep:
(At least back speeds slightly lower than forward - i can't imagine german engineers making U-Boot running faster backward!)

Have you tested the stock files? with and without electric engine ratios patch?

Hum...no...just the update you posted...

:03: :)

If you saw some errors/mistakes when you're testing something, always test the stock files too.. thus we always know where is issue.. I mean is this a stock issue or it comes from the current mod.. :yep:

Here we go, sorry for the delay guys. :oops:

Let's start by having a look into a real U-boat telegraph:

http://www.sharkhunters.com/X12.jpg

As in game, it had 5 ahead and 4 astern speed orders. The 5 ahead speed orders are (starting from the slowest one):

Kleine Fahrt - "dead slow"
Langsame Fahrt - "slow speed"
Halbe Fahrt - "half speed"
Große Fahrt - "3/4 speed"
Äußerste Kraft - "emergency speed"

Astern bells followed the same naming, except for the fact that they didn't include "Große Fahrt". The German VIIC manual mentions two additional speeds orders:

2x Große Fahrt - "4/5 full speed"
3x Äußerste Kraft - "utmost speed"

They wont be included among the preset speed orders, but I will set the remaining ones as if they were. It involves that the fastest bell ratios set in U-boat cfg files (i.e. AheadFlank)will get a value lesser than 1 (=maximum speed/rpm).

Let's talk about our sources now. Of them, only the VIIC manual specifies German telegraph orders together with their corresponding speeds/rpm. As for the British report, it doesn't give any special detail about diesel speed names, and for electric propulsion speeds, only English telegraph orders are listed. Yet, only a rough correspondence can be found between the German and the English terminology as far as telegraph order and ratios are involved. As a consequence, I would suggest to adopt engine ratios derived from the German manual, using data from the Admiralty report only as a cross-reference, and for calculation of speed/rpm gradients of "average" u-boats. Boat's cfg files would therefore change as follows:

where:

AheadSlow = Kleine Fahrt (ahead)
AheadOneThird = Langsame Fahrt (ahead)
AheadStandard = Halbe Fahrt (ahead)
AheadFull = Große Fahrt (ahead)
AheadFlank = Äußerste Kraft (ahead)
BackSlow = Kleine Fahrt (astern)
BackStandard = Langsame Fahrt (astern)
BackFull = Halbe Fahrt (astern)
BackEmergency = Äußerste Kraft (astern)

This time, I have calculted the ratios over the fastest speed order (3x Äußerste Kraft) listed in our source (3x Äußerste Kraft), which corresponds respectiveli to 480 and 300 rpm for diesel and electric propulsion.

As for maximum speeds I have calculated them as I did yesterday. That is to say that they were calculated over the aformentioned maximum rpm's and over average speed/rpm gradients, which take both our sources into account (i.e: 0.036575 kts/rpm for diesel propulsion and 0.0271 kts/rpm for electric propulsion). The new maximum speeds are therefore 17.56 surfaced and 8.13 submerged. I have merged the new settings into Volodya's patch (only for types VII and VIIC); here are the files, if you want to test them:

Finally, the below schemes summarize data reported by our sources, my suggested settings and their espected rpm / speed outputs. Starting from them and from the patch posted above, we can further adjust my suggested settings, and try to understand what is wrong about ahead/astern ratios not being applied as supposed :up:

:o Nice work! :up:
Will test that.
You said only for VII and VIIC types...:hmmm: VIIA too?
