摘要
对一种新型云爆药剂及其试验装置进行了外场静爆试验，并对其爆炸／冲击波参数和后续燃烧现象进行研究。结果表明：总装药量为30kg的试验弹其爆炸火球最大直径可达17．4m，是原始装药直径的75．65倍。从所测爆炸场超压曲线发现存在前后两个正压作用区，第二个正压区呈现较好的规律性；二次冲击波在火球区外形成，火球区内是后续燃烧反应对爆炸波加载而引起的压缩波积累压力平台；二次冲击波峰值压力不小于第一个冲击波的40％，二次冲量占总冲量的12．5％～43．7％，其对爆炸／冲击波威力的贡献不可忽略。
The outfield static blast experiment of a new type single-event fuel air explosive （ SEFAE ） and its test equipment was carried out. The blast/shock wave parameters were measured and the after-burning phenomena were studied. Results show that the biggest blast fireball diameter of the testing bomb with 30 kg SEFAE is 17.4 m, which is 76.65 times of the original diameter of charge. According to the overpressure curves, two positive pressure zones are found. The second positive pressure zone which is aroused by after-burning is in regulation. The second shock wave is formed outside fireball and the pressure fiat roof accumulated by compressed waves is inside fireball. The peak value of the second shock wave is no less than 40% of the first one＇s and the second impulse is 12.5% -43.7% of overall impulse. Thus the effect of the second shock wave on blast/shock wave power can not be neglected.
