Increasing the Performance of Shaped Charges by Using High-Modulus Ceramic Lens Assemblies

The possibilities of increasing the performance of shaped charges by using lens assemblies made of high-modulus ceramics are considered. In this case, an increase in the loading parameters of a shaped-charge liner can be achieved if the detonation wave enveloping the lens will propagate through the precompressed but unreacted explosive. Precompression of the explosive charge without detonation initiation can be achieved by its shock desensitization by the advancing wave transmitted through the ceramic lens. Numerical simulation of detonation wave propagation in a shaped charge with different lens assemblies provides a promising outlook for the use of compound lenses in which the inner part adjacent to the axis of symmetry is made of high-modulus ceramics and the outer part is made of an inert material.
