Abstract:
The process of cutoff of low-velocity areas of a shaped-charge jet with the help of a reverse-action shaped charge adjacent to the base of the shaped charge and having an axial channel where the shaped-charge jet passes is considered. The operation of the cutoff device and the shaped charge is synchronized by choosing an appropriate thickness and material of the cutoff device liner. An engineering method for synchronization of operation of the cutoff device and the shaped charge is proposed. Recommendations on choosing the cutoff device are given for a particular case of practical interest.
Keywords:
