Abstract |
In this work the influence of the characteristics ofthematerial ofthe striker
(cumulative jet or projectile), moving at speeds of 2-10 km/s, on the volume
of the resulting crater in a metal target, has been studied. The dependence
ofthe crater volume in an aluminum alloy target ofCu-Al, W-Cu-Pb-Al composites,
and steel St45 for a PTFE-Cu composite, were investigated. The outer diameter
and height of the shaped charges were 26 and 28, and 31 and 33 mm, respectively.
The mass of the explosive (phlegmatized hexogen) in these charges was 10
and 18 g. A comparison was made between the ratios of the kinetic energy of the
striker to the volume of the crater formed for the composites PTFE-Al, PTFE-Cu,
Cu-Al, Ni-Al, W-Cu-Pb, and porous materials Cu and Al. It was demonstrated
that the chemical interaction of the components of the porous Cu-Al and Ni-Al
composites during penetration into the barrier is possible at an impact velocity
of at least 2-3 km/s and a porosity of at least 30%. |
