底部排气弹点火具特性对底排工作影响的分析

点火具是底排弹中一个起着特殊作用的部件,对底排弹的射程及散布有着不可忽视的影响.本文着重分析不同类型点火具,及不同质量点火剂,在目前底排弹试验中所带来的影响及其作用,试图寻求一种能增加射程,减少散布的方法。

AN ANALYSIS OF THE INFLUENCE OF IGNITER ON THE PROPERTIES OF THE BASE BLEED PROJECTILE

The igniter is a part that has special function in the base bleed projectile.The test shows that, it not only plays an imporant role in igniting effect, but also hasinfluence to a great extent on the burning of base bleed and on the range dispersionof the base bleed projectile. This paper gives emphasis on the analysis of the func-tion and influence on present base bleed projectile for some types of igniter and dif-ferent weight of propellant. Finaly, try to get the method of increasing the range andreducing the dispersion of base bleed projectile.
