The article discusses the numerical simulation of interaction between shaped charge jet
(SCJ) and explosive reactive armor (ERA) units containing different materials. Numeri-
cal simulation shows a small advantage of ERA with ceramic plates over other materials
in case of equal mass of high explosive and plates. Protection ability value of such reac-
tive armor is 0,95L
0
and 0,93L
0
(L
0
is the depth of penetration cavern in homogeneous
steel armor) for ERA with steel plates. Extension of hole diameter for ceramic ERA plates
is much smaller, thus ceramic ERA plates can interact with SCJ directly after ERA high
explosive detonation. It is obtained by numerical simulation that value of protection abil-
ity for reactive armor with inert filler is the smallest (0,87 L
0
).
Keywords
: shaped charge jet, explosive reactive armor, non-explosive reactive armor,
inert filler, steel and ceramic plates.
