Optimization of penetration into geological and concrete shields by impactor with jet thruster

Gabi Ben-Dor, Anatoly Dubinsky and Tov Elperin

Vol. 3 (2008), No. 4, 707–727
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.
