底排点火具参数设计及其与底排药柱的匹配

Parameter Design of Base Bleed Igniter and Matching with Pellet in Base Bleed Projectile

介绍了点火具静止测时装置的设计思路，论述了点火具的主要技术指标──常温燃烧时间的控制以及提高其精度的途径；研究了点火具喷气孔径、装药量对底排弹弹道性能的影响以及点火具技术参数与底排药柱力学性能之间的匹配关系。

The design idea of static meassuring time device of igniter was introduced in thispaper. The main qualifications of igniter were discussed. The influence of the jet hole diameterand charge weight of igniter on ballistic performance of base bleed projectile and the matching relation between the technical parameters of igniter and the mechanical properties of the pellet inbase bleed projectile were studied.
