Acceleration device based on high explosive charge which contains high modular ceramic tube

Modelling of fast jet formation under explosion collision of two-layer alumina/copper tubes

“…Usage of acceleration devices based on HE charges containing alumina ceramic tubes for generation of ceramic streams with velocities up to 11.0 -12.4 km/s was experimentally substantiated in paper [5]. Theoretical velocity limit was estimated as 19.0 km/s for alumina and 32.5 km/s for BN.…”

“…Theoretical velocity limit was estimated as 19.0 km/s for alumina and 32.5 km/s for BN. Figure 1 shows the movement of a cumulative jet formed from an alumina ceramic tube [5]. One can see that the jet is a flow of dispersed ceramic particles.…”

Influence of the clearance between initiating unit and main high explosive charge on jet perforator efficiency

“…ODVAX code implements the explicit finite differences numerical method of individual particles [5], based on the representation of continuum as population of interacting Lagrangian particles, which move on Eulerian grid. A brief description of the software and numerical method can be found in [6].…”
