Rig for silent running
 

Alright folks, I asked this a long time ago, but can't find the thread.

Calling for "Silent Running" the speed goes to 3 knots. I want 1 knot.

Which file do I edit?

Many thanks.

If you use TWoS, on silent running you have 55 RPM and 1 knot.

Regards.

Thanks but not quite what I was asking for.

I known how to hit the "Z" key and hit 1 knot on speed.

But there used to be a place in the files where you could "edit" that so that when you hit the "Z", it went to 1 knot.

I have the same question. Why, when you are in quiet motion (55 rpm), when you press Z or F7, the rpm increase to more than 100 (ahead slow instead set speed 1 knots)? I would like to do it right - so that these buttons lead to silent movement.

For what it’s worth, in reality, the lowest RPMs did not mean the most silent speed. Somebody should mod it if they haven’t done so already to make it so say 100 RPM or slightly higher is more quiet. That would be more in line with reality.

It comes down to 2 factors: resonance, and the motor fields. For the first, every component, even of a U-boat, has a resonance . Just like an old truck, sometimes the bumper rattled at slow speed, until you reach a certain speed where the rattling of the bumper ceased, only to start again at a little higher speed. Every boat went through listening tests as part of its workup. And almost without exception, from the data I have seen, the quietest RPM is typically at 100 or just above 100. The other factor that contributes to this is that in order to achieve a very low RPM like 50 or 55, the motor fields need to be at full excitation, and they get very hot. Per the E-motor manual, in order to run like that for any extended period of time required the motors’ blowers to be on to cool them, and that made noise. So these are all factors as to why slow RPM does not mean the most silent operation. Hopefully somebody can take that into consideration if they are trying to create a new mod or modify an existing one.

How does this fit in with the descriptions and clues? Silent rpm ~55 is written everywhere, the player seems to be waiting for these exact parameters, but in fact we have 110 with "ahead slow". For a long time I didn’t understand why destroyers in silent mode could hear me so well, until I read this forum and started set 1 knots manually. But be that as it may, when you press rig for silent running, increasing the speed from a quiet 55 seems to me to be a mistake or a flaw.

It’s just that the game incorrectly assumes that the lowest RPM is the quietest, and the AI perceives it that way. It’s a mistake that pervades pretty much all existing U-boat games. Maybe at some point it can be changed.

gents,

you know more than you think you know: you walked around the solution.

when a kaleun orders salient routine by pressing the proper key, two things happen:

1. certain pre-programmed, interior noise factors are reduced. we cannot change these.
2. speed is set to slow speed.

#1 is unchangeable and so it will not be discussed here.
#2 is changeable by switching the speed EOT to display knots, and then setting your speed manually that way. you can also change the EOT settings in the Submarine.CFG file in the \data\submarine folder.

so, set silent routine, then set your speed to 1 or somewhere between 1 and 2 kts.

or modify the EOT such that the lowest speed setting will generate speed between 1 and 2 kt.

2. This is exactly what I wanted to do, but I didn’t find a way. I will be grateful if you teach me. In Submarine.CFG i seen parameters of switcher: AllStop=0.00
AheadSlow=0.195
AheadOneThird=0.39
I can’t figure out what figure would correspond to 1 knot, or ~55 rpm. But the most important thing is that if I do find the correct value, will F7 also set it to 55 rpm?

upd: I replaced 0.195 with 0.09. No changes, the rpm is the same - 110.

1. that’s the problem, if I’m running at low rpm, but without turning on silent running (so that torpedoes are reloaded, for example), turning on the so-called silent running will increase the speed and they will hear me, unless I demonstrate a cat-like reaction and take over control, returning rpm to its previous value.

I understand what you are talking about, but still, we are playing a game with certain rules and everyone wants to leave the battle alive, for this we will have to adapt to the game rules, even if they differ from the real world.

in the CFG file, what is the published, MaxSpeedSubmerged?
that's the speed that is used by the game to calculate RPM.

so, .09 times 8 kts (example maxspeedsubmerged) yields .72 kts.
.72 kts should put your boat's RPM at the lowest possible RPM.

players are not allowed to see or change the RPM vs kts table. it has been a source of frustration since the earliest of SH games.

are you giving the boat sufficient time to decrease speed from the previous speed?

That is section [ElectricEngineProperties]
I tried changing the values, but nothing changes.

Those kind of changes won't take effect until you start another career. Maybe the next patrol, depending upon how SH5 works as compared to SH4... You could also attempt to find the setting in your Save game folder and maybe get away with directly editing it there. :salute:

one more question - how do two commands work - F7, which combines rig for silent running from EO and silent speed from CE?
Logically, I would expect that the first would reduce noise throughout the sub (repairs, torpedoes, propellers), and the second would affect exclusively the propeller speed, without affecting repairs and torpedoes. But in fact it turns out that it makes no difference which button you press, they will work the same and will suspend operations with torpedoes and repairs. I see this as incorrect behavior.
Where could I be wrong?
