Change of depth...
 

Guys,

are we sure that the changing depth time is not correct?...

I've made some tests myself and it "feels" right. I mean, when you make a little change of depth, it takes longer because the sub is not that inclined ...but when you order a larger depth change, the sub is more inclined and it goes deeper quicker...

Am I missing something here?... :hmm:

The physics engine is not tuned correctly in the BETA patch. The buoyant force is greater than the weight of the subs.

Notice that when you are at max depth and max speed and hit emergency surface, your submarine will pull G's close to a Fighter Aircraft on the way up. :hmm:

Mhm...still I don't get it. That should bring it to a final equilibrium buoyancy... :hmm:

Well, I trust you, guys...just fix what you think should be fixed

That is to say, the subs should act as if they are heavier than they are in terms of their interaction with the water, regardless of trim.

They should not act like balloons full of air, even with emergency surface.

akula should dive faster from surface to 50 meters 4 minuets 17 seconds last time a sub done that was a british K class and it was sinking.

at that speed a skula should be able to get down to 50 meters in less than 3 minuets even 2.5 minuets

Down angle
 

I have tested this and sadly I don't know how to post my results on the site.
But let me say from real life, submarines are able and do make very steep decents. Doing a 20 degree down angle is not all that uncommon, DW, during my testing never seems to go over 7 degrees either up or down, now I did not test emergency blow.
Sonar737 wrote about an evolution subs do that is quite common, Angles and Dangles, we do really steep and rapid depth changes, I have seen 30 degrees. It is fun, good training for planesmen, you defintely find out if you are stowed for sea, and more importantly it lets you practice manuvers you would use in evasion.
Please consider this, the Helmsmen and planesmen have seat belts and use them on orders to prepare for steep angles, everyone else just hangs on. That will tell you that these boats are setup to and will do really steep angles.
One thing I noted in testing, AI will change speed when you go up-average of 6-7 knots, and will go back to the ordered bell during the last 100 feet of the ascent. Also deep depth to PD is much faster, almost like you gave the tanks a shot of air, which you don't normally do. Subs basically fly when submerged and nuke boats have the power reserve so do not use air except in an emergency, they do use the low pressure blower to fully surface of course.
Ballast tanks are full of water, you cycle vents on a regular basis to insure so maybe DW is seeing some type of influence regarding denisty on an up bubble, but I have never heard of that. It defintely increases speed on its own.
I will caution all players one thing I have discovered in DW is during evasive manuvers mind your depth because all the boats tend to sink lower on a hard turn which is new to DW. I have hit the bottom several times until I started testing why, and the debrief screen will tell you you "crashed". I have also discovered DW will over run ordered depth on a dive. E.G. you order 700 feet and during descent change you mind say you are at 400 feet when you decide and you order 500 feet, the boat will go-on an average-60-75 feet below the new ordered depth. In real life this would not happen as the helmsmen would catch the boat, and believe me they are good at putting the OOD right on, they all take great pride in it. I suggest all of you watch the control room screen during some manuvers the helm indicators flop around something awful, and often during a dive or surface the planes will indicate zero. The trim indicator will indicate an up or down bubble, but not the palnes.

Mhm...how difficult is it to make things work right?. I mean, a manual control of the planes as it is for the rudder would be a good step forward...

Well, let me think back to the last time someone tried to code a physics engine that would successful account for playable submarines, surface ships, and airplatforms. :hmm:

Oh wait, no one has ever done that before SCS and Dangerous Waters. :o

It's hard, to answer your question. :up:

But at least the manual controllable planes... :cry:

Yep this speed of depth change topic is old, old hat.

But did you read the notes flagged up at the start of the 1.03 patch instalation process ? -
Oooooh no sorry its '' only a Beta.'' Give me a break ! :nope:

:hmm: BF1942?

...Was a game and not a high fidelity simulation.

I can sink ships on the highest difficulty. No autocrews. How much of a fidelity sim can DW be?

Well, I read somewhere on this site that the US Navy is using it to train its crew... :up:

Actually, they use something that's derived from the game...
