The effect of underwater shock wave on different target plates has been studied.An underwater shock wave generator(shock tube) was used to study the interactions between water and different constructed targets which act as shock wave mitigation.Target plates,composed of sandwich of two aluminum sheets with rubber and foam in between,were prepared and studied.For comparison,the target plates composed of triple aluminum sheets were tested.The study includes the testing of the selected plates in water under the effect of different peak pressures and the analysis of the results.The strain gauge data and displacement sensors results showed that the multi-layer plates have higher level of underwater shock wave mitigation than the triple aluminum plates with strain and deflection of nearly 50%. 展开更多

The effect of thermite mixture based on aluminum and ferric oxides for ammunition neutralization has been studied and tested. Thermochemical calculations have been carried out for different percentage of Al using Chemical Equilibrium Code to expect the highest performance thermite mixture used for shaped charge ordnance disposal. Densities and enthalpy of different formulations have been calculated and demonstrated. The optimized thermite formulation has been prepared experimentally using cold isostatic pressing technique, which exhibited relatively high density and high burning rate thermite mixture. The produced green product compacted powder mixture was tested against small caliber shaped charge bomblet for neutralization. Theoretical and experimental results showed that the prepared thermite mixture containing 33% of aluminum as a fuel with ferric oxide can be successfully used for shaped charge ordnance disposal. 展开更多
