Rig for silent running

Sandman_28054 · 07-20-20, 07:09 AM

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.

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.
