Parametric Study on the Ground Landing of Re-Entry Capsule Using Coupled Eulerian–Lagrangian Method
摘要
This paper presents a parametric study on a re-entry capsule during ground landing. The dynamic characteristics and behavior of the re-entry capsule during ground landing were analyzed using the coupled Eulerian–Lagrangian method. In this study, a simplified re-entry capsule considering the Hayabusa re-entry capsule model was employed, and a parametric study of the landing conditions was performed. Specifically, landing velocity, posture at ground impact, and landing soil were considered as the parameters for ground landing. A tilted posture of the capsule was found to be more conducive to safe ground landing by absorbing the impact energy during the landing process.
