Abstract

In order to improve the underwater damage ability of underwater weapons

a non-axisymmetric composite shaped charge (NACSC) with high explosive heat charge on the outer layer and high detonation velocity charge on the inner layer is proposed.A simulation model of NACSC is established through numerical simulation

theoretical analysis and experimental verification of underwater forming.The underwater formation of NACSC is optimally designed.The optimized results show that the detonation wave is obviously asymmetric in the axial and radial directions of the composite charge

and the shaped charge penetrator is formed into a flat shape due to this influence.Adding a shell structure between inner and outer charges can enhance the reflected pressure of symmetric inner charge acting on liner

reduce the transmitted pressure of asymmetric outer charge acting on liner

and weaken the influence of detonation products of asymmetric outer charge on the forming process of shaped charge penetrator.The experimental results show that the optimized NACSC can form an effective shaped charge penetrator under the water

and penetrate the double-layer spaced target under the condition of 5 times the diameter and explosion height of the inner charge.The influence characteristics of non-axisymmetric detonation pressure on the forming morphology

head velocity

length and other factors of shaped charge penetrator are obtained

and the forming ability and penetration performance of NACSC are verified

which provides support for expanding the application of shaped charge warhead in underwater complex environment and compact space.
