Abstract
The article presents the influence of the wave shaper position on the jet formation and penetration depth of a shaped charge, which uses the liner of the PG-7VM warhead by numerical method and experimental method. The results show that, when moving the plexiglass wave shaper position towards the liner apex, the jet tip velocity and the jet velocity gradient increase. In addition, the results of the study also pointed out the existence of the wave shaper position at which the penetration depth is greatest. They indicate a match between the simulation and experimental results. The differences between simulated and experimental penetration depth are less than 15%. The results of the study are the basis for the evaluation of the influence of the wave shaper position on the liner collapse and the reasonable use of the wave shaper in the structure of the shaped charge.
Highlights
During the explosion process, it is possible to control the detonation wave to focus the energy of the charge that makes up the line, region, and surface where there are extremely high density and pressure
The penetration depth results calculated by the simulation method (Fig. 13) show that, when the wave shaper position approaches the top of the liner, the penetration depth increases gradually and decreases
The influence of the wave shaper position on the jet formation and the penetration depth to the steel target is presented in this study
Summary
It is possible to control the detonation wave to focus the energy of the charge that makes up the line, region, and surface where there are extremely high density and pressure. It may be encountered in the structure of a shaped charge and an explosively formed penetrator. One of the detonation wave control schemes to increase the penetration depth of the shaped charge is the use of a wave shaper in its structure. Er, its position has an important influence on the penetration depth of the shaped charge. This conclusion has been presented in several documents. The quantitative research of the influence of the wave shaper position on the penetration depth of the shaped charge given in some documents was not fully evaluated [1,2,3,4,5]
