Abstract:

The technical route of fuze self-neutralisation and self-deactivating of cluster submunitions is analyzed,and the self-neutralisation routes of two kinds of cluster submunition fuze are introduced. A reliability model of cluster submunition fuze is established,and the reliability of all the modules in the fuze is figured out using the experiment results, and the comprehensive firing rate and self-neutralisation rate are simulated using Monte Carlo method. The experiment and simulation results indicate that the reliability of fuze self-damage/ self-neutralisation module is higher than that of firing device. Also, the fuze comprehensive firing rate of sub-munitions launched by multiple launch rocket system(MLRS) is difficult to achieve 99%. Besides, self-neutralisation device is auto-checked.
