Abstract:
First, we hypothesize that a serious accident related to the use of salutes may be caused by the simultaneous explosion of several salutes or salute components, resulting in an unexpected, abnormally strong shock wave. To prove our theory, we conducted three experiments. In Experiment 1, we examined the transfer of the explosion between salutes with one donor to shed light on the properties of the charges. Experiment 2, which we conducted to examine the transfer in the case of two donors, revealed a localized effect of the transfer. In Experiment 3, we measured the pressure during explosion using a pressure-sensing film, which was used to create pressure contour lines. Our experiments reveal that there is an area of abnormally high pressure, a finding which supports our hypothesis.
