Abstract: 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.

 

Key words: warhead dispersion; center tube explosion dispersion; gas pressure; storage test and measurement; low power consumption
