飞片起爆技术研究

A STUDY ON THE TECHINIQUE OF FLYING PLATE DETONATION

给出飞片起爆猛炸药技术中计算飞片速度的理论公式及其实测结果,两者有较好的一致性。通过计算速度与临界速度的比较,可判断所设计飞片发生器结构的合理性。文中还研究了影响飞片可靠、稳定地引爆猛炸药的诸因素,给出了一些实验结果。从中看出,最主要的影响因素是飞片材料、尺寸和受主装药的性质。此外,还应注意飞片发生器的输入冲量的影响。

This paper deals with the flying plate detonation of secondary explosives. Formulae for calculation of the flyer velocity are given, together with the experimentally measured velocities. The two are found to be in good agreement. By comparing the critical velocity for the detonation of a secondary explosive with the calculated value, one can judge whether the design of the flying-plate construction is soundly based. Factors that influence the reliability and stability of detonation of the secondary explosive were experimentally investigated. From the experimental results it can be seen that the most important factors are the meterial and size of the flying-plate and characteristics of the secondary explosive (acceptor). At the same time, attention should be paid to the input stimulus necessary to set off explosion.
