摘要
为减少战斗部内部装药补缩量不足导致的装药缺陷,提高装药质量,增加装药密度和装药量,优化炸药的爆轰性能,增强战斗部的毁伤威力,文中在常规热塑态装药的工艺基础上,以DNAN基含铝炸药为对象,提出了一种战斗部用DNAN基炸药热塑态装药改进工艺。该改进工艺采取保证保温装置温度、减缓注药速度、减少炸药转运、减小降温梯度、延长保温时间以及重新设计装药补缩装置等措施,以提高战斗部装药的内部质量,减少缺陷,进而提高战斗部的安全性。改进工艺前后的对比试验表明,改进后的战斗部装药密度从1.70 g/cm^3提高到1.78 g/cm^3,增加了4.71%;战斗部装药量和装药内部质量均得到提升,弥补了装药缺陷,抑制了缩孔和空隙的产生。热塑态装药改进工艺简单易行、实用可靠,可为大、中型战斗部热塑态装药质量的提高提供参考。
To solve the problem of insufficient explosive charge shrinkage compensation in the warhead, raise the charge density and charge quantity, and optimize the detonation performance of the explosive, an improved thermoplastic charge technique of DNAN-based aluminized explosive for the warhead was proposed on the basis of the conventional thermoplastic charge technique of DNAN-based explosive. In this improved technique, the measures of ensuring the temperature of thermal insulation device, slowing down the charging speed, reducing the transport of explosives and the temperature gradient, prolonging the heat preservation time and redesigning the charge shrinkage compensation device were taken in order to improve the internal quality of warhead charge, reduce the defects and improve the safety of warhead. Comparative test of the conventional and improved techniques showed that the improved charge density of the warhead increased from 1.70 g/cm^3 to 1.78 g/cm^3, increasing by 4.71%. Both the charge quantity and the internal quality of charge were improved, which made up for the charge defects and restrained the generation of shrinkage cavities and voids. This improved thermoplastic charge technique is simple, practical and reliable.
