Replica scale modelling of long rod tank penetrators
conference paper
Experiments and simulations have been conducted using scale size tungsten alloy penetrators at ordnance velocity against an oblique plate array consisting of an inert sandwich and a base armour. The penetrators are made from 2 types of tungsten alloy with different tensile strength. Two scale sizes have been used: scale size 1:6 using simple cylindrical rods and scale size 1:3 with a more realistic geometry including a threaded shaft section. The purpose of the experiments is to establish the difference in behaviour between the 2 types of penetrators and to assess the differences between the scale size 1:6, scale size 1:3 and full scale results. The purpose of the hydrocode simulations is to assess the influence on penetrator performance of the yaw angle of the penetrator prior to impact.
