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.
Keywords:
high-speed impact, melting, evaporation, space man-made debris.
