Ballistics

[Logi]

Well my program pretty much auto-generates a whole skew of constants so it should work.

You said you used the F-formula in your thread, however if didn't mention the quality constants you used for F;

Now all we need to do is to fill out the following table*:

   1880 Solid shot      1890 High Explosive      1895 Semi Armour-Piercing      1905 Armour-Piercing      1908 Capped shells
1880 Cast Iron (belt)      ?      ?      ?      ?      ?
   " (deck)      ?      ?      ?      ?      ?
1890 Compound (belt)      ?      ?      ?      ?      ?
   " (deck)      ?      ?      ?      ?      ?
1900 Krupp Cemented (belt)      ?      ?      ?      ?      ?
   " (deck)      ?      ?      ?      ?      ?
1915 All Imp. KC types (belt)      ?      ?      ?      ?      ?
   " (deck)      ?      ?      ?      ?      ?


Feedback is appreciated.

Well, that is the constant I'm lacking.

Stuff

I'm not quite following, but using those functions to calculate the range? As of now, my model does calculations via step-by-step model. It runs through the equations every second until the shell impacts the water. So how would those functions work for such a model?



On another note, I'm trying to writing the hydrodynamic portion, but that'll take me a bit as I have some books to read on that subject.

By hydrodynamic, do you mean you are going to calculate shots that fall short and hit the ship below the waterline?

I'm going to calculate the motion of the ship as well as underwater hits. As of now there is only the ballistics portion written with nothing on the ship or underwater shell travel.

I'm getting freakishly large numbers for armor penetration running the F-formula. Just to make sure, is the F-formula in metric or imperial?

Speed and weight are imperial (ft/s and pound), afaIk.
It's just a matter of the constant you are using though, and units shouldn't matter for diameter/penetration anyway.
