Estimation for peak delivery of cylindrical propellants by multi-entry augers into reflectors of pulsating explosive devices

The article presents some results of numerical studies on determining the peak supply of cylindrical propellants by multi-entry augers into reflectors of pulsating explosive devices, and also determined the mass of augers with entire and hollow shafts depending on the number of their entries. Respectively the research object is reusable solid-fuel pulsating explosive devices of multi-purpose application, and the research subject is a high-speed mechanism with adjustable supply of cylindrical propellants in the working zone (to the reflector of pulsating explosive devices). The research purpose consist to numerically assess the effect for the entry and mass of augers, as well as the geometric characteristics of the cylindrical propellants used, on the upper specific rate of their delivery to the working zone of the reflector. The research limits include augers with 2 to 7 entries, as well as hexogen and TNT charges with mass of 6 to 18 g and density of 1 g per cube cm, with diameter 20 mm and length 25 mm.
