Abstract

High-speed penetration into soil, rock, concrete, and ice by impactors equipped with a jet thruster is optimized using analytical and numerical methods. It is shown that using a jet thruster with optimum burning programs bears considerable promise for increasing the depth of penetration. In this study, we used modified Young's penetration equations with a smooth approximation of the dependence between the depth of penetration and impact velocity for the description of impactor-shield interaction.
