【摘要】 以外径Φ45.5 mm、内径Φ8.2 mm、长度40 mm、密度1.61 g.cm-3的双基推进剂空心药柱为研究对象,在推进剂装药结构中设置一定间隙,并在间隙中分别填充空气、水、沙、木屑、橡胶片、含氧化剂弹性体等材料,研究了间隙及填充物对推进剂爆速及其爆炸作用效应的影响。结果表明:当间隙为2 mm,在间隙中填充空气时,主发药柱被激发后,被发药柱发生爆炸。当间隙大于3 mm,在间隙中仍填充空气时,被发药柱不发生爆炸;当间隙中填充其它材料后,则被发药柱可以被激发,爆速超过6000 m.s-1,10 mm厚的A3钢板能够被击穿。更多还原

【Abstract】 By using the double base propellant with hollow center,the outer diameter Φ45.5 mm,inner diameter Φ8.2 mm,the length 40 mm and the density 1.61 g·cm^-3,the distances between the initiating booster and sympathetic charge were set into a series of （different） clearances,and these gaps were filled with materials including air,water,sand,sawdust,flake of rubber and elastic gel with（oxide）.The effect of clearances and different fillers on new explosive detonation velocities and actions were studied.The results show that with 2 mm clearance filled with air,when the main charge is aroused,the sympathetic charge is equipped with detonation performance;with larger than 3 mm clearance filled with air,when the main charge is aroused,the sympathetic charge is not equipped with detonation performance;but after the same clearance are filled with other materials,the sympathetic charges are formed into steady（detonation）,and the latter（detonation） velocities are more than 6000 m·s^-1,and the A3 steel of 10 mm thick can be broken down.更多还原
