子母弹抛撒火药燃气压力测试系统设计及理论分析

针对子母弹中心爆管抛撒环境恶劣及传统测试系统安装布线困难等问题,设计了一种存储测试系统,用于完成子母弹抛撒火药燃气压力的采集。文中阐述了系统工作原理及低功耗设计方案,推导了圆柱状密实接触中心管爆炸开舱战斗部内部压力变化过程的算式,并进行了相应的实弹测试试验。经试验表明,该系统能够完整的记录抛撒过程中火药燃气压力的变化过程并与理论推导相吻合,符合试验标准。

Design and theoretical analysis of test system for propellants' gas pressure in warhead

Aiming at harsh environment of cluster bombs center tube explosion dispersion and difficulties in installation of traditional test systems,a storage test system based on 16-bit ultra-low power microcontroller MSP430 is designed in order to acquire gas pressure during cluster bombs dispersion.To meet the requirement of low power consumption,the working states of system＇s modules during data acquisition are elaborated and the equation to calculate the gas pressure change during cylindrical center tube opening the hatch is deduced.The field test is conducted and good test results are obtained.
