Abstract
Hydraulic ram concerns the dynamic loading and catastrophic
failure of liquid filled fuel tanks impacted by high
speed projectiles. Hydraulic ram is divided into two phases:
shock phase and cavity phase. The shock phase was studied.
Theoretical predictions of shock radius versus time were compared
with experimental results. The theory was found to be
reasonably accurate for blunt shaped projectiles.
Included in the theory were predictions of shock pressure
and pressure profiles behind the shock. Theoretical pressures
are presented graphically but were not validated by
experiment.
Velocity decay of the projectiles in the liquid was investigated
and correlated with theory to provide information
for further studies of the cavity phase.
