ABSTRACT

A large-scale shadowgraph technique was applied to a fuel tank simulator in order to visualize the pressure waves generated by hydrodynamic ram. Tungsten, steel, and aluminum spherical projectiles were fired into a fuel tank simulator, capable of containing 3785 liters (1000 gal) of liquid, to simulate hydrodynamic ram and generate pressure waves within the liquid. The pressure waves moving through the large-scale simulator were visualized using a shadowgraph technique that comprised of a 1000-W Xenon arc lamp and a reflective sheet. This shadowgraph technique was aided by a high-speed video and the results were compared to pressure transducer signals acquired at several locations within the tank. The comparison was used to provide a better understanding of each phase of the hydrodynamic ram process and produced clear images of the initial impact wave, which moved through the tank, and several cavity implosions, corresponding to the maximum pressure measured.
