一种平板式微小型爆炸序列的传爆性能研究

Detonation Transfer Performance of a Flat-sheet Style and Micro-scale Explosive Train

设计了一种平板式微小型爆炸序列,将HMX基导爆药JO-9C(Ⅲ型)在薄板空腔内压装成长条形代替柱形导爆药,在其两端分别使用轴向与条形导爆药表面垂直的微小型电雷管和传爆管作为输入和输出,形成包含两个直角的传爆路径。对比研究了不同温度(高温、低温、常温)条件下的爆炸序列在条形导爆药高度为0.8 mm和1.8 mm时的传爆性能。结果表明:微小型电雷管、传爆管与药高为0.8 mm的条形导爆药组成双直角传爆路径的爆炸序列能够逐级传爆;爆炸序列温度越高,作用后对约束件破坏性越大。

A flat-sheet style and micro-scale explosive train of loaded HMX-base lead explosive JO-9C（ Ⅲ） in a thin sheet to form strip-shaped lead explosive instead of columned lead explosive was designed. Micro-scale electric detonator and booster in two terminals of explosive train, whose axes are upright with surface of strip-shaped lead explosive, were used as input and output of explosive train, and the detonation transfer route which includes two right-angle was formed finally. The detonation transfer performances of explosive train with strip-shaped lead explosive with the thickness of 1.8 mm and 0.8 mm under different temperature （high temperature, low temperature, room temperature）conditions were studied and compared. Results show the detonation of the explosive train with double right-angle route composed of micro-scale electric detonator, booster and strip-shaped lead explosive with the thickness of 0.8 mm can transfer step by step. The higher the temperature of explosive train, the greater the destructivity to the restrictions after action.
