Hydraulic Ram Pressure Measurements.
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.
