进行了一系列小规模爆炸试验，以评估装满水的容器和轮胎减轻装甲车辆爆炸负荷的可能性。实验比较了空水容器、满水容器、与钢板对峙的满水容器、充气轮胎和充水轮胎对钢板上动量传递和变形的影响。水容器和轮胎加水都减少了板块的整体运动，但这只是与系统质量的增加相同的量。因此，车辆质量的等量增加将产生相同的效果。相比之下，充气轮胎能够减缓动量传递，其程度比它提供的质量增加要大。局部变形实验发现，使用充满水的容器可能比同等增加钢的质量更有效地减轻钢板的变形。装载的时间尺度表明，水的主要缓解机制是动量提取，因为在目标装载之前没有足够的时间进行水的分解和蒸发。还需要进一步的工作来确认结果的可扩展性，但这项工作表明，有可能使用水箱作为装甲车爆炸缓解系统的一部分。
A series of small scale explosive experiments were performed to evaluate the potential for water filled containers and tyres to mitigate blast loading on armoured vehicles. The experiments compared the effects of an empty water container, a full water container, a full water container at a standoff from the plate, an air-filled tyre, and a water-filled tyre on the momentum transfer and deformation on a steel plate. Both the water containers and addition of water to the tyre reduced the global motion of the plate, but this was only by the same amount as the increase in mass of the system. Hence an equivalent increase in the vehicle mass would provide the same effect. In contrast, the air-filled tyre was able to mitigate the momentum transfer by a larger amount than the increase in mass it provided. The localised deformation experiments found that the use of a water filled container was likely to be more effective at mitigating the deformation of a steel plate than an equivalent increase in mass of the steel. The timescale of the loading indicated that the primary mitigation mechanism of the water was momentum extraction as there was insufficient time for water breakup and evaporation to occur prior to target loading. Further work is still required to confirm the scalability of the results, but this work indicates the potential to use water tanks as part of the blast mitigation system of an armoured vehicle.
