摘要:
为实现某型延时起爆装置预定的延期时间，选用点火药硼/硝酸钾作为毫秒级延期药，通过对延期药原材料及装药结构的分析，尽可能地控制延期时间精度。主要针对延期药的原材料、装药密度、壳体材料、装药结构以及装药条件等对延期时间影响的机理及试验对比进行分析。经研究发现，延期药的延期时间和延期精度受诸多因素影响，一般来说药剂粒度适中且颗粒均匀，或提高装药压力，延期时间精度较高。其他因素（如装药壳体、装药结构、环境条件等）在不同程度上对延期时间精度也有影响，减少这些因素的影响对提高延期时间精度是十分必要的。
Abstract:
As a millisecond delay agent B/KNO3 igniting powder was selected as the military allowable ignition agent to achieve the delay time for a delayed detonation device. The delay time accuracy was controlled as much as possible through the analysis of the delay material and charging structure. Raw delay materials, charge density, shell material, charge structure, charge conditions and other influencing factors, and the method of test comparison were analyzed. It is found that the delay time and its precision are affected by many factors. In general, the delay time accuracy is higher when the particle size of the igniting powder is moderate and even, or the charging pressure is increased. Other factors, such as charging shell, charging structure, and environmental conditions, would make some contribution to accuracy. Therefore, it is necessary to reduce the influence of these factors in improving the delay time accuracy.
