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. Analytical models have been proposed for the shock phase pressures by Yurkovich and for the drag phase pressures by Lundstrom. Comparisons were made between hydraulic ram fuel cell entry wall strains predicted using several loading models and those determined experimentally. A reasonable correlation was achieved but more work must be done to permit predictions of hydraulic ram strains accurate enough for the purpose of fuel cell design.
