Sub Cavitation Parameters?

[captinjoehenry]

Subs have CavitationParameters and I am wondering what the numbers mean as I am messing around with fictional high speed subs :P

"The in-game formula for this is 'Cavitation depth = 20 * SpeedInKnots - 100'. What this means is that for every 5 knots of extra speed, cavitation happens 100 feet earlier. "

http://gameplay.tips/guides/653-cold-waters.html

20 * 5 knots -100 = 0 feet
20 * 10 knots -100 = 100 feet
20 * 15 knots -100 = 200 feet
20 * 30 knots -100 = 500 feet

I am talking about the line in the submarines data file. It looks like this:
CavitationParameters=15,-155
And I am wondering what those 2 numbers mean and how they effect the subs cavitation speed.

Based on goldfish716 (http://www.subsim.com/radioroom/member.php?u=370302) post, one would guess that the parameters that you spoke of "CavitationParameters=a, b" (with a= 15, and b = -155 in your example), would be plugged into the formula "'Cavitation depth = a * SpeedInKnots - b'".

But the above is just a guess, I can't test it right now...

[goldfish716]

Right. The first number is the number of feet you have to go (per knot) before cavitation stops.

The second number moves the whole plot up or down.

Its essentially just a linear equation like you learned in school ax+b=Y.

Where x is knots and y is depth.

So the deeper we go, the faster and the less likely for cavitation?

As where more shallow, more likely to cavitate unless slower prop rotation = slower boat speed?

As in more dense the water, the less bubble creation = less noise?
(for those of us that suck at ax+b=Y :-p


The reverse is true that

I found that this combination lets my particular sub go at 500 knots with no cavitation even at the surface. Sure not balanced but I don't care as I am playing for the fun. So if you want to have some fun and unbalance your sub go ahead and change your parameters to these. Just make sure to backup a copy of your original file so you can revert back if you desire to.
