Abstract

Abstract

Graded-impedance shield is a kind of structure against space debris with excellent protection performance verified by experiments. Graded wave impedance material is used as its core buffer. In order to further optimize the design of graded wave impedance material and promote the engineering application of graded-impedance shield, it is necessary to deeply understand the protection mechanism of the shield against hypervelocity impact. The difference of debris cloud characteristics is an important factor affecting the protection performance of shields against space debris. Further study on the debris cloud characteristics of graded-impedance shield and comparison with aluminum alloy Whipple shield with the same areal density can deepen the understanding of the protection mechanism of graded-impedance shield against hypervelocity impact. In this paper, the hypervelocity impact experiments were carried out at 3.5, 5.0 and 6.5 km/s for the graded-impedance shield and aluminum alloy Whipple shield with the same areal density. The characteristics of the debris cloud formed by the projectile impacting the graded wave impedance material and aluminum alloy material with the same areal density were compared after the experiment, and the characteristics of debris cloud fragmentation was quantitatively analyzed and compared through numerical simulation, including the characteristics of cloud mass, quantity and temperature distribution. As results, it is shown that the fragmentation characteristics of projectile fragments in debris cloud structure are obviously different when the projectile impacts the graded wave impedance material and aluminum alloy material, respectively. When the impact wave impedance gradient material is used, the projectile head is broken more fully, and the projectile lateral expansion degree is increased. In the high-speed section (6.5 km/s), due to the joint action of impedance gradient and material melting effect for the graded wave impedance material, the delamination phenomenon appears in the head of debris cloud. The results show that the change of debris cloud characteristics under hypervelocity impact is one of the key factors that the protective performance of graded wave impedance material is better than that of the aluminum alloy with the same areal density.
