摘要:
为研究不同装药结构的爆速及其对钢板的破坏影响,以外径为45.5 mm、内径为8.2 mm、密度为1.61 g/cm3的双基推进剂单孔药柱为研究对象,在推进剂结构中设置不同单元药柱长度、不同单元药柱间隙长度,在间隙中有无填充氧化剂弹性体。通过爆速测试和见证板方法得到:在充填间隙后,装药结构完全爆轰,爆速范围为6.7~7.25 km/s;在间隙无充填时,随着间隙长度的增加,爆炸性能下降,在单元药柱长度低于50 mm且间隙长度大于3 mm后不能爆轰。测试得到了单元药柱长80 mm,间隙为5 mm装药结构的爆速为1.9 km/s,并用见证板和高速摄影手段进行了验证。
Abstract:
To research the detonation velocity of different charge structures and their destruction influence on steel,a double base propellant with single hole is studied,with the outer diameter of 45.5 mm,the inner diameter of 8.2 mm and the density of 1.61 g/cm3.Different unit length,different unit gap length and whether the gap is filled with a oxidizer elastomer is set in the propellant structures.The results of detonation velocity test and testimony board show that the charge structures are detonated completely and the detonation velocity changes from 6.7 km/s to 7.25 km/s if the gaps are filled with oxidizer elastomer.If the gaps are empty,the detonation performance is decreased with the increase of the gap length,and the charge structure can not be detonated if the unit length is less than 50 mm and the gap length is more than 3 mm.The test results show the detonation velocity of the charge structure with the unit length of 80 mm and the gap length of 5 mm is 1.9 km/s,which is verified through testimony board which speed photograph.
