To analyze the shielding performance of Whipple bumpers, it is essential to clarify the characteristics of a debris cloud that is created owing to a hypervelocity impact. However, lesser attention has been paid on studies on the debris clouds produced by oblique impacts compared to those produced by normal impacts. We thus evaluate the damage of the pressure walls after oblique impacts. Two energy indices are proposed that can determine the destructive capability to the pressure wall. The proposed energy indices are related to the kinematic energy of the debris clouds. These energy indices are demonstrated to show the destructive capability and to uniformly evaluate the damage of the pressure wall. The spatial distributions of the kinetic energy are calculated by the smoothed particle hydrodynamics simulation. In addition to the simulation, impact experiments are conducted with two pieces of apparatus: a two-stage light gas sun and a single-stage powder gun. We discussed the correlation between the characteristics of the debris clouds at the oblique impacts and the damage of the pressure walls.

“…Wang et al [7] established the analysis model of the moving process of the debris cloud formed by the hypervelocity impact of projectiles with different shapes on the multi-layer plate structure. When Bohl et al [8] studied the hypervelocity impact trajectory characteristics of non-parallel double-layer plate structure, the limit size of the projectile in some cases was determined by SPH numerical simulation, and the sensitivity of the angle between the two plates was analyzed. Yan et al [9] carried out a numerical simulation about the hypervelocity impact of the Whipple protective structure and analyzed the debris cloud morphology at different time points in the whole process.…”

Aiming at the Whipple protective structure with a front plate of 3 mm 6061-T6 aluminum alloy and a rear plate of 3 mm 6061-T6 aluminum alloy, two different projectiles were used to conduct experimental research on the low-velocity impact Whipple protective structure. The relationship between the corresponding damage mode and the kinetic energy property of the projectile was analyzed. At the same time, the penetration velocity limit of the Whipple protective structure was explored to obtain the damage characteristics of this protective structure under cm-level low-velocity impact. The damage characteristics of the small projectile to the protection mechanism within the relative impact velocity of 650 m/s provide theoretical and technical support for the later spacecraft reinforcement optimization design.
