And here's the link to the TGA with the Ausdampfverfahren method:

All,

I have posted video demonstrations of the Ausdampfverfahren and Auswanderungsverfahren, see links at bottom of second and third posts.

How to calculate Ausdampfverfahren with my DR Slide Rule mod!

Place your speed under 90°, read target speed for the TDC opposite to target bearing.

First example from derstosstrupp video:
3.5 x sin(69.5°) = 3.2783

Second example from derstosstrupp video:
4.2 x sin(54°) = 3.3978

Thanks Tycho, I wouldn't have figured that out by myself, I would have just wasted time picking up a calculator, when all I really need is one click to slide out your slide rule, and one sliding movement to match my speed with 90 degrees. Then I just look what the result is.

Doing this with a calculator would have required me to push a calculator button 10 times AND getting my eyes off the game. The slide rule way is 5 times less the work and unhindered concentration on the game

Tycho,

This is outstanding. I've added this to my game. "Target speed" for both Ausdampfverfahren and Auswanderungsverfahren can be computed using this, and, as sublynx said, no need to get eyes off game.

Well done!

Great post,

One question though. I try to figure out the maths behind it. Why do you use a AOB of 90? Wouldn't you require the actual AOB?

Just tried my 2nd attempt at the Auswanderungsverfahren method and whoah, I think this is one method to keep. First attempt I botched up but the 2nd hit home. Took a bit of studying the video and I wrote down on paper my own version of the steps for quick reference.

Two things I wonder about:
Is this method dependent on fast setting for the torpedo or will it work equally well on any speed setting?

Where does the number 1820 come from? I understand it's there to convert from metric to nautical units but 1820 is not a number that rings any bell. I was expecting 1852 but for some reason, 1820 seems to work splendidly.

Been away for a while, but since returned. I have since fleshed out the Auswanderungsverfahren In a comprehensive guide which I have linked to my signature. Hopefully this is helpful in guiding folks through an engagement from A-to-Z, in a manner that seems to be historical based on what I’ve read.

A 90° AOB is used in the Ausdampfverfahren Due to the convenience of the sine of 90 being 1 - Makes the calculation more straightforward. Also, the method can be used with any speed setting, as you are still reliant on the TDC To set the shot up.

Good stuff, thanks!

(old thread reborn). Good method, but only for submerged attacks due to exposing your side profile to the target resulting in a high chance of being spotted in a surface attack.

Very true! Check out my comprehensive Tutorial, that has recommendations for night attacks as well as incorporating these methods.

Yes, been following your links. Outstanding, thanks for the work !

Hi again;
Been reading your "Comprehensive......" work. Question: On the overhaul, you state get to the point where the target indicates 0 aob.
My understanding of 0 degrees aob would mean the target's bow would be pointing directly at either my bow or my stern; either is 0 aob.
Is this your interpretation also ?
