Experimental Study on the Short-Duration Shock Initiation of Explosives

摘要

The loading technique of explosives shocked initiation by high-velocity flyer generated by electric gun is introduced simply at first. By means of this technique as well as Up-and-Down method, the shock sensitivities of HNS and PETN are studied primarily in experiments. The results show that with the average particle size 1μm and 90 %TMD of pressed density the shock sensitivity of HNS is lower than that of PETN, that is to say that refined HNS is inerter than refined PETN, and for PETN, with higher pressed density the shock sensitivity is lower on the condition of same particle size 1μm.
