Stop the damned engine!

Ula Jolly · 07-23-05, 07:05 PM

I'm not really sure how submarines work when it comes to this, but if I order "Stop the engine", CAN WE PLEASE TURN IT OFF?

I want to nail my helmsman to the spinning prop so maybe HE can muffle its sounds, because no matter what vessel, in no matter what seastate, the engine will NEVER stop running.

Something for 1.02, perhaps? :hmm:

Some subs keep the prop spinning even when stopped to continue lubing the shaft and to prevent leaking around the shaft seal.

How about the noise? If they want a halt - yet to spin the prop - it can't be very fast, and the noise must be minimal. I want a minimal passive signature, but have no way to obtain one.

Depending on the class of sub, they may be able to change the angle of the screw blades to ensure that there is no forward motion and minimal or no cavitation. spinning at such slow speeds and with the screw in this configuration would be as good as having the screw not moving. In DW when all stopped passive signiture is no problem i find.

The screw is an animation. It has nothing to do with the sound you are emitting.

Being all stop is not going to make a difference if you are trying to be quiet. The sub still has the reactor running to power the generator so you can have electricity for all the systems on board.

if say an oscar class submarine stops her screw then water comes in through the shaft this is what killed the men of the kursk or one factor of it

it well know that the oscars have to have special clamps to put on the shaft when the screws do not turn otherwise you would end up flooding the place same with DW i think just going on with real world knowlage

kgsuarez · 07-24-05, 03:48 PM

I doubt that DW models anything like that.

The reason for the never stopping screw is simple. SCS didn't think that anyone would want to stop their sub, so they didn't bother modeling anything like this.

None of the (playable) subs in this game have any business stopping... Well, that's how I feel about it at least.

im forever stopping my sub thats all i do stop start stop start i need to stop my sub dont fancy going head on to a ice burg etc that and i also stop to hide and on sea floor sometimes

Caseck · 07-24-05, 04:08 PM

Is he talking RADIATED NOISE, as in the sound/speed fix? Or is he just talking the noise you hear from sub's crew positions?

Kapitan · 07-24-05, 04:12 PM

who what eh ? who talking to who? quotes please

Ula Jolly · 07-24-05, 04:38 PM

"He" is talking about a fluctuating sound that sounds bubbly, much the one one has when MOVING.

Try placing a Trafalgar to your 90 deg running at 3, and at an equal distance, to your 270, a Trafalgar standing still. Isn't the difference in noise very, very little?

Kapitan · 07-24-05, 04:47 PM

hmmm yeah that is true

is 1.02 out yet?

Ula Jolly · 07-24-05, 06:19 PM

Nope. That's why we can continue to make suggestions.
