Torpedo Spread Angle Calculator

Nisgeis · 10-10-08, 12:51 PM

I've done a quick replica of part of the gizmo that the USS Torsk has on its gryo angle solver bay that allows you to calculate the formula:

No. of degrees total spread = (Target length in feet / 1,000) * (2,000 / Torpedo Run yds) * Sin(Torpedo Track Angle)

It does this in a graphical way, that you can easily and quickly trace out to get the total spread angle for a target. It's much easier than trying to work it out!

Now, it's a prototype at the moment and I had to make a few adjustemnts because I can't see anywhere in the game that tells you what length the topedo run is (it was on the gyro angle solver RL). Would anyone who is interested, particularly in manual targetting like to test it? It works to calculate spreads for auto targeting as well, but it less important.

EDIT: Released here: http://files.filefront.com/TSAC+v21p.../fileinfo.html. Get the torpedo run time from the attack map and follow the instructions.
EDIT2: Changed file to V2.1 as V2 had a slight error in it.

"I have awesome, but would anyone want it?" Silly question, of course we would!

Rockin Robbins · 10-10-08, 02:39 PM

I volunteer! That is a great improvement to the by guess and by golly spread.

And it would get me out of my Dick O'Kane attack rut. It's about time I found some innovative wrinkles in conventional targeting.

Do I get feedback this time?

.

If there's one thing I've learned, it's that the more realistic your mod/guide, the less people are interested in it. Personally, I think that plotting a target from radar readings and getting a track is the best way to use your stopwatch with it's authentic world war two tick-tock sound, but what do I know.

Count me in

PM me or post here a link to what you want to test, I think I can be able to give it a try this weekend

I would like to help test your gizmo. I use MoBo alot for intercepting but would love something to assist with spead angle.

It would be neat having devices (working models) that were used in the war such as you are referring to. They also had a thing-of-a-gig called a "was/is". Maybe it is the same item you are talking about or one that does something else, I can't remember.

what you are talking about is an is/was, and this is old news here at subsim - many of us have made our own and use them regularly

the original thread, including pdfs for making your own

http://www.subsim.com/radioroom/show...ighlight=iswas

original instructions for using it

http://www.hnsa.org/doc/attackfinder/index.htm

note, this tool is not the same as a spread angle calculator

breadcatcher101 · 10-12-08, 11:37 AM

An is/was it is/was then.

I had read about it's use in one of my books, forgot which one, maybe "Clear the Bridge", about the Tang. Anyway I checked out the link and I have a new project now in trying to make one.

I thank you for providing the link and for setting me straight on the correct name.

Nisgeis · 10-12-08, 01:31 PM

Thanks to all the victims, er, I mean volunteers. I'll send you a PM with the download link in it on Monday. What I have atm is a replica of what is on the Torsk, but I can think of some improvements.

Rockin Robbins · 10-12-08, 02:52 PM

Clearing a spot for it in my S-boat. Hope my TDC operator is up to it. He just missed four of four in a Dick O'Kane. Shooting torpedoes is harder in RFB and the sugar boat! No ice cream for him tonight though...

Matilda · 10-12-08, 03:54 PM

Looking forward to it. Just let me know.

Nisgeis · 10-13-08, 06:39 AM

Testers should all now have a PM from me.

Matilda · 10-13-08, 12:07 PM

I got your PM and DL'ed the file. Went over the examples and have a decent grasp of how it works. I'll let you know what kind of results I get in game.

Nisgeis · 10-13-08, 03:43 PM

Looking forward to feedback. One really useful thing is the maximum torpedo run time. You can use this to see if your shots will actually reach the target. I was a bit surprised how low some of the run times were for maximum range. It'll cut down on some wastage I'm sure.
