Abstract:
The pressure-profile measurement results obtained in the shock-wave front in bromoform upon detonation of HMX charges of diameter 40 mm and length 22–110 mm are reported. The initial density of the charges was 1.81 g/cm$^3$. In all the experiments, a monotonic decrease in pressure occurred, and a chemical peak was not observed. With increase in the charge length, the maximum pressure values first increase and then decrease. An analysis of the pressure measurement results shows that, for the given charge size and the initiation system used, the process of HMX detonation occurs in a nonstationary regime.
