- Abstract
Simulation and hypervelocity tests were carried out, to analyze the shielding performance of N-shape configuration under impact conditions that the impact points were not on the center of buffer and the impact angles were ±10°and ±20°. The range of impact velocity was from 4.6km/s to 4.8km/s, and the diameter of aluminium projectile was 5.5mm. Results showed that the shielding performance of N-shape configuration declined when projectile impacted the top of the configuration, however, its performance was improved when projectile impacted the bottom of the configuration. The shielding performance of N-shape configuration decreased when the impact angle of projectile was 10°or 20°, and the shielding performance declined slightly when the impact angle of projectile was -10°, however, its performance was improved obviously when the impact angle of projectile was -20°. The performance anisotropy of the N-shape configuration was verified preliminary in the study. Key words: Hypervelocity impact, Shield configuration, Oblique impact, Debris
