Abstract. Simple models for the internal, external and terminal ballistics of
a tank gun firing a long rod penetrator are described
and used to determine the penetration that can be achieved
for a typical system. The models also show the effect
on penetration of modifications to the penetrator geometry, charge parameters
and barrel length. The results show that there are many
interdependencies, and that an apparently simple modification to improve penetration
may be accompanied by unacceptable consequences elsewhere, particularly high breech
pressure and sabot stresses, and an inappropriate all-burnt position. It
is also shown that these effects can only be mitigated
by further modifications which tend to negate the apparent improvement.
The most promising improvement in penetration is based on more
energetic propellant and is about 12%.
