Study on damage of reactive fragment impacting partially-filled fuel tank

Abstract The damage effect of PTFE/Al/W reactive fragment impacting partially-filled fuel tank is investigated by combining the ballistic gun experiment and theoretical analysis. experimental results show that, with impact velocity ranging from 806m/s to 1331m/s, fragments successfully perforate front plate cause flash-ignition fuel/air mixture, but does not fail obviously. Based on results, a temperature analysis model debris developed energy release characteristic material convective heat transfer model. result shows that high-temperature can effectively ignite which in good agreement results.
