Non-homogeneous armor(NHA) in WW2
Re: Non-homogeneous armor(NHA) in WW2
Some great info on the matter, something I will sort through at the latter date: http://www.navweaps.com/index_nathan/Mi ... enetration

Re: Non-homogeneous armor(NHA) in WW2
Thanks, Boy those early graphs are primitive. CV/1 they tried to make the logrithmic range scales with a typewriter. Coverting to metric is confounding.
Re: Non-homogeneous armor(NHA) in WW2
What irritates me most about the graphs is the quality of scan. I can barely read anything on the last three images - it probably does not help that I don't own the best display.

They must of been scanned long ago or the paper didn't age well.seppw wrote: ↑09 Jan 2019, 14:57What irritates me most about the graphs is the quality of scan. I can barely read anything on the last three images - it probably does not help that I don't own the best display.
Here is what a firing table of the 2 - pdr would look like if used the strike velocity of the Russian table. It is pretty close to the graph range numbers but they don't have tic marks so their positions are hard to judge.
Re: Non-homogeneous armor(NHA) in WW2
Whelm. do you also have CV/28? That is a revised CV/1 and will probably have a better range scale.
Re: Non-homogeneous armor(NHA) in WW2
Thanks, whelm! This scan is of great quality.
Re: Non-homogeneous armor(NHA) in WW2
Thank whelm. CV/28 fixes problems with CV/1 ranges beyond 1000 yds.
I've put those CVs to use as wiki or Warthunder doesn't seem to want to use real historical data.

Thanks. Two marks of Littlejohn. Something I didn't know.

This is pretty much exactly what I've been looking for: https://apps.dtic.mil/dtic/tr/fulltext/u2/a954860.pdf
And also this is somewhat informative: https://apps.dtic.mil/dtic/tr/fulltext/u2/a954407.pdf

Re: Non-homogeneous armor(NHA) in WW2
Something I've realized while reading this: if in the live tests on proving grounds the researches are using specially made ammunition, it's likely to have better average quality than the mass produced ammo used in the field tests. Since the performance of FHA is heavily dependent on whether it can break the projectile or not, we have another source of error to account for.

Re: Non-homogeneous armor(NHA) in WW2
The Pz III FH plates are interesting because they happened to shatter early 2pdr capped A.P. as if they had no cap at all. It´s not a rare event (if the shot head is too hard, f.e.) but what is interesting here is that this happened without the plate beeing much inferior to a regular homogenious armor, indicating a good balance between toughness and hardening and little, adverse scaling effects.
