Abstract:
A method and results of calculation of parameters of long-term shock loading of solids, generated by a gas-dynamic former containing a combined charge with explosive initiation, are described. A calculation model based on the concepts of the hydrodynamic theory of detonation and on the theory of combustion of condensed substances is considered. The forcing pressure and the physical laws of combustion of the combined charge are determined in calculations and experiments. The dynamics of the process is studied by an example of calculation of parameters of the loaded solid acceleration pulse in the case of initiation and combustion of a charge consisting of two batches of high explosives: black powder and pyroxylin powder. The effect of the combined charge parameters and combustion-chamber size on the parameters of the shock loading pulse is studied.
