"Journal of Battlefield Technology" Vol 1-1 pp 1 a article was
published on HEAT developement and standoff
penetration chart was published for Steel,Copper and Aluminum cone
shaped liners.....here
are provisional figures taken from the chart.
Standoff in cone diameters
Liner | 1.0 2.0 3.0 4.0 5.0 6.0
------------+-----------------------------------
Aluminum | 1.0 1.5 2.0 2.4 2.5 2.5
Steel | 2.8 3.1 3.5 3.5 3.2 2.8 Vs mild steel?
Steel | 3.0 3.5 3.5 3.1 2.6 2.1 Vs ~180 BHN
Copper | 3.1 4.1 4.8 5.0 4.3 3.8 Vs mild steel?
Copper | 4.2 4.4 4.2 3.8 3.4 2.8 Vs 340 BHN
result is the penetration in cone diameters
