Abstract
Hydraulic ram concerns the dynamic loads and catastrophic
failure of liquid-filled fuel tanks impacted by high speed
projectiles. Hydraulic ram is divided into two phases:
the shock phase and the drag phase. Analytic models have
been proposed for the shock phase by Yurkovich and for the
drag phase by Lundstrom. An attempt was made to correlate
these theoretical pressure predictions with experimental
data obtained from 0.222 caliber projectiles impacting a
small water-filled tank. This comparison showed reasonable
correlation but indicates that more work must be done to
permit predictions of hydraulic ram pressures accurate
enough for the purpose of fuel cell design.
