摘　要：针对某火工装置在飞行试验中出现入水后熄灭现象，对装药进行了水下燃烧等试验研究，研究结果表明，药剂具有较好的水下燃烧性能。对于飞行中入水熄灭问题，分析认为主要是受气象条件影响，在伞的拖拽下，灌入的水不断冲刷燃面，导致燃面温度无法维持在燃点以上，从而熄灭。

Abstract：According to the quenching phenomena of some fire device entering water in flight experiment，experiments such as charge burning in water are done.Experiment results show that the charge has excellent burn⁃ing performance in water.The main reason of quenching in flight experiment while into water is the long duration towing of parachute.On this condition，water pours into case and swash the burning surface constantly，so tem⁃perature of the burning surface can't be kept above burning point，then quench happens.
