摘　　要：采用点火瞬时性模拟试验装置和旋转中止燃烧试验装置实验研究了点火药为ZrH2 +PbO2 的GC -4 5点火具和点火药为Mg +PTFE的改进型点火具对AP/HTPB底排药柱的点火。实验结果表明 ,前者存在点火延滞期长、燃烧侵蚀现象严重 ,以致造成射弹射程和密集度下降 ,因此建议采用以MgThis paper deals with the ignition process of the base bleed grain consisting of NH 4ClO 4 (AP) and hydro terminated polybutadiene (HTPB) by the GC-45 igniter with the ignition composition ZrH 2+PbO 2 and modified igniter with the ignition composition Mg+PTFE. The simulation device of ignition instantaneity and the rotated combustion interruption device are used in the experiment. It is proved in the experiment that the GC-45 igniter has the problem of long ignition delay and heavy ablation when it is used to ignite the AP/HTPB base bleed grain, and the problems are the important reason that decreased range and ballistic precision. It is suggested that the igniter should be improved.
