Abstract

The penetration of an aluminum jet into an aluminum alloy target with a speed of 8–11 km/s is investigated. An analysis of the kinetics and parameters of introduction, and the condition of the surface of the cavity after penetration suggests that the hydrodynamic nature of penetration is violated at speeds of more than 9 km/s because of fusion of interacting metals. The results of the study are intended to develop screen protection for spacecraft from the most dangerous fragments of space debris.

9 km / s以上速度下相变对铝合金相互作用的影响

摘要

研究了铝射流以8-11 km / s的速度穿透到铝合金靶中的情况。对引入的动力学和参数以及渗透后的腔表面状况的分析表明，由于相互作用的金属融合，以超过9 km / s的速度违反了渗透的流体力学性质。这项研究的结果旨在为航天器提供保护，使其免受最危险的空间碎片碎片的侵害。
