title = "Distribution of debris cloud caused by hypervelocity impact on AL-foam shield",
abstract = "It's important to improve and optimize the shields used to protect the manned elements against impacts of micro-meteoroids and orbital debris. Tests have identified that metallic foams have a good shielding performance against M/OD hypervelocity impact, so metallic foams may play a key role in the structural design of manned spacecraft and satellite in the future. To investigate the distribution of debris clouds caused by impact on Al-foam shields compared to solid aluminum, numerical simulations were carried out in the velocity range of 3-9km/s at normal incidence angle. The distributions of mass and kinetic energy of debris cloud were obtained at different angles. The mass distribution of debris cloud caused by impact on Al-foam bumper shows two peaks at different velocities within 0-45 degrees. While the kinetic energy distribution of debris cloud shows only one peak within 0-15 degrees. The mass and kinetic energy of debris cloud caused by impact on Al-foam bumper are more dispersive at higher velocities than those of solid aluminum bumper. This feature will help to decrease the risk of spacecrafts against space debris with high speed.",
