Abstract

Abstract:

To study the behind-target damage enhancement effects and mechanism of the reactive material double-layered liner (RM-DLL) shaped charge penetrating into the target plates,the penetration and deflagration behaviors of composite jet impacting a multi-layer spaced target are studied.The damage behaviors and mechanism of the reactive composite jet against multi-spaced target plates are investigated through experiment,numerical simulation and theoretical analysis.The experimental results show that the reactive composite jet can effectively damage the multi-layer spaced target composed of 8 mm thick steel targets and 10 mm thick aluminum plates.it can penetrate into 7-9 layers of target plates within the standoff range of 1.0-1.5 CD.The petal shaped edge damage and large opening damage of 8 mm steel targets are the most serious within the penetration depth range of 2.0-2.7 CD.The maximum damage area diameter of the steel target is 2.5 CD.At a penetration depth of 1-4 CD,it causes a petal shaped edge damage and large openings on 8 mm steel plates,with a maximum opening diameter of 2.5 CD.The simulated and calculated results indicate that the collapse effect of detonation waves,the material and structure of liner,and the penetration process determine the energy release behavior of reactive composite jet.The deformation energy changes of target plates at different positions are basically consistent with the distribution of reactivation mass of reactive materials.The metal jet of the composite jet head penetrates on the target plate in advance,which can avoid wasting a large amount of energetic materials in the early stage of penetration.Most of the reactive materials are brought into the interior of the target,fully utilizing the reaction energy release of the reactive materials,and achieving the enhanced damage effect inside the target through the combined action of penetration and deflagration.By adjusting the action conditions of jet,it is possible to control the position of reactive materials to enhance target damage as needed.The maximum energy release of ractive materials is achieved within the depth range of 2.3~3.0 CD,achieving the best damage effect.

Key words: reactive composite jet, energy release position, damage effect, spaced target
